  • It left the rules behind

    ALTO Used the Rulebook’s Numbers. It Left the Rules Behind.

    ALTO’s new economic report takes two key figures from an Ontario appraisal manual and names that manual as its source. The manual attaches conditions to those figures. The report uses the figures and leaves the conditions out.

    ⚠ The Document Under Examination

    In August 2026 ALTO published Canada’s Moment: The Economic Opportunity of High-Speed Rail, an 83-page report setting out the economic case for the Toronto–Québec City high-speed rail corridor. Its central figure is $49.5 billion in benefits to travellers and society, set against a construction cost of $60 to $90 billion.

    To turn sixty years of future benefits into one number in today’s dollars, the report needs two things: a rate at which to shrink future benefits back to present value, and a price for an hour of a traveller’s time. For both, it names one source — a public appraisal manual published by Metrolinx, the Government of Ontario’s transit agency for the Toronto and Hamilton region.

    Critical Finding

    The Metrolinx manual does not simply publish those two numbers. It publishes them as part of a package. For any project over $500 million, the same manual requires that the numbers be re-tested at different values, that results be reported as a range rather than a single figure, that early-stage construction costs be topped up to correct for known optimism, and that the project’s benefit-to-cost ratio be published. ALTO’s project is roughly a hundred times larger than that threshold.

    None of those requirements appears in ALTO’s report. There is no test of the discount rate, no range around the $49.5 billion, no optimism adjustment to the cost, and no benefit-cost ratio. The two numbers were carried across. The conditions attached to them were not.

    This brief does not argue that ALTO used the wrong discount rate. The rate it used is a mainstream, defensible choice. The finding is narrower and, we think, harder to answer: the report presents a set of choices as though they were simply facts, and a reader has no way of knowing that anything was chosen at all.

    Why this matters

    Imagine a builder quotes you a price for an extension. Asked where the figures come from, they name the standard industry pricing guide. That guide does set those rates. It also says that on a job this size the quote must show a high and a low figure rather than a single number, must add a fixed percentage on top because early quotes are almost always too low, and must set the total against the value of what you are getting.

    The builder uses the guide’s rates and does none of the rest. The quote may well be sound. You have no way of telling — and nothing on the page tells you that anything was left out.

    That is the situation this brief describes. ALTO’s economic report takes two figures from a public appraisal manual and names that manual as its source. The same manual attaches a set of mandatory checks to those figures for projects of this size. The figures were used. The checks are absent, and their absence is not disclosed.

    It matters because of what rests on the result. The $49.5 billion benefit figure is the number now appearing in news coverage and public statements as the reason to build a railway costing $60 to $90 billion of public money, ahead of a federal decision in 2029. Presented as a single figure with no range, it reads as something measured. The report’s own tables call it an upper estimate.

    What the report gives you

    One benefit figure, $49.5 billion, built on a rate and an hourly value of time presented without explanation of where they came from or what else was possible. No range. No benefit-to-cost ratio.

    What its own cited source requires

    The same figures re-tested at different values, results published as a range with a confidence level, a 64 per cent top-up on early-stage construction costs, and the benefit-to-cost ratio reported.

    What that leaves a reader with

    No way to judge how firm the headline number is — and no indication in the document that this is a question worth asking.

    One thing this brief does not do: argue that the numbers ALTO chose are wrong, or that high-speed rail is a bad idea. The rate it used is a mainstream choice, and the one test the manual requires would, if anything, make the benefits look larger. The ask is simply that the tests be run and published, as the cited manual says they must be.

    The Two Numbers

    What the report borrowed, and from where

    3.5%
    the discount rate ALTO uses, taken from the Metrolinx manual
    Appendix A, footnote 65
    $22.32

    justified as following Metrolinx method
    64%
    the top-up the same manual requires on construction costs at this stage of design
    not applied in the report

    The discount rate. A benefit that arrives in 2085 is not worth as much to us today as the same benefit next year. Economists handle this by shrinking future amounts back to a present-day value at a fixed annual percentage — the discount rate. ALTO uses 3.5 per cent a year, applied over a sixty-year period. The rate matters enormously: over sixty years, small changes to it move the headline benefit figure by billions.

    The value of time. Most of the $49.5 billion is not cash. It is hours — time that travellers would otherwise have spent on the road or waiting at an airport. To put a dollar figure on those hours, you have to decide what an hour is worth. ALTO uses $22.32, and applies the same figure to every trip: business or holiday, commuter or tourist. The report tells us its own ridership model did separate business from non-business travel, and that this distinction was set aside in favour of one blended figure.

    Where both come from. The footnote attached to the discount rate cites one document and one only: the Business Case Manual Volume 2: Guidance, published by Metrolinx in August 2021. The single blended value of time is defended on the grounds that it follows Metrolinx method. So a manual written for regional transit projects in the Toronto and Hamilton area is the published authority for how a national intercity railway has been appraised.

    Metrolinx guidance is not binding on a federal Crown corporation, and nothing here suggests otherwise. But a citation carries the terms of the thing cited. If you name a manual as your authority, it is fair to look at what else that manual says on the same page.

    The Manual’s Own Terms

    The numbers come as a set, not a menu

    The 3.5 per cent rate appears in a table of standard parameters. The text introducing that table is direct about their status: any departure from them has to be explicitly agreed during the work, with a clear justification recorded. It is a list of defaults you may leave, provided you say so. Below is how each of those defaults is treated in ALTO’s report.

    What the Metrolinx manual specifiesWhat ALTO’s report does
    Discount rate: 3.5 per cent. The rate at which future benefits are shrunk to present value.3.5 per cent. Adopted exactly as specified, and correctly footnoted to the manual.
    Status:Carried across
    Value of time: one blended figure. A single hourly value across all modes and all trip purposes, rather than separate values for business and leisure travel.One blended figure, $22.32. Adopted, and expressly justified by reference to the manual — in preference to the business and non-business split that ALTO’s own ridership model had already produced.
    Status:Carried across
    Growth cap: stop escalating benefits 30 years out. The manual caps growth in the inputs thirty years after the base year, expressly to reflect the fact that nobody can see that far ahead. User benefits are named as covered by the cap.Applied to two small lines, not the big one. Accident rates are capped after twenty years, and vehicle emission factors run to 2050. No cap is stated on travel-time benefits — which are 78 per cent of the total.
    Status:Applied selectively
    One price year throughout. All values discounted and escalated to a single common year, fixed at the start of the study, so that every figure in the document is in the same money.Two price years in one report. The appraisal and the capital cost are in 2024 dollars; the economy-wide GDP result is in 2019 dollars.
    Status:Not consistent
    Test the value of time at 0.75 per cent real growth. The manual’s base case assumes the value of an hour does not rise in real terms — but pairs that assumption with a required test of what happens if it does.Zero growth assumed; no test run. The assumption was carried across. The test that the manual attaches to the assumption was not.
    Status:Left behind

    One footnote on the money. Adjusting the manual’s 2021 value of time for inflation to 2024 gives roughly $21.40 — within a few per cent of ALTO’s $22.32. We are not claiming ALTO derived its figure that way, and ALTO does not say how it did. The point is simply that the figure sits where you would expect a Metrolinx-derived figure to sit, which makes the omission of the accompanying test harder to explain as an oversight.

    The Missing Tests

    What a project this size is supposed to publish

    The Metrolinx manual scales its requirements to the size of the project. Anything above $500 million is treated as large scale, and a specific list of tests and disclosures becomes mandatory. ALTO’s cost estimate is $60 to $90 billion — roughly a hundred times that threshold. Here is that list, and where each item stands in ALTO’s report.

    Re-run the numbers at a different discount rate

    The manual requires the calculation be repeated at 2.5 per cent so the reader can see how sensitive the answer is to the rate. Not done, and not mentioned. Note the direction here: the required test is at a lower rate, which would make the benefits look larger. Nothing in the manual supports an argument that ALTO’s rate is too generous. What it supports is the narrower point that the manual’s author expects the rate to be tested and the test to be shown.

    Re-run the numbers with a rising value of time

    Required at 0.75 per cent real growth per year. Not done.

    Run the costs and assumptions through a range analysis

    The manual requires costs and modelling assumptions be run thousands of times with the inputs varied, and the result reported as a range with a stated confidence level. Not done.

    Report the odds that the project is worth doing

    The manual asks specifically for the probability that benefits exceed costs. Not reported — the report publishes no benefit-cost ratio at all.

    Publish the standard indicators

    Net present value, benefit-cost ratio, capital utilisation, return on investment, internal rate of return. None published.

    Model low, medium and high growth scenarios

    Required, with the ridership growth rate stated for each. A ridership range is shown; the underlying growth scenarios are not stated.

    This is not a theoretical requirement

    The manual works the method through on a real example: an extension of the Yonge subway line in Toronto, at an early stage of design. A single cost estimate of $5.65 billion becomes a range of $6.16 to $6.84 billion, with the confidence level attached. The reader is shown a central figure, a spread, and how sure anyone is about it.

    That project is roughly one per cent the size of ALTO. On uncertainty, the manual ALTO cites tells its reader more about a subway extension than ALTO’s report tells its reader about a national railway.

    The Missing Lower Number

    The report concedes a range it never publishes

    The two tables carrying the entire $49.5 billion case are both headed with the words upper estimate. Every figure in the narrative is prefixed the same way: up to 24 million riders, up to 9.3 billion hours saved, up to 400 fatalities avoided, up to 39.1 million tonnes of emissions.

    An upper estimate is one end of a range. The other end does not appear anywhere in the document.

    The claim built on top of those figures goes further still. The report states that the benefits hold across a wide range of scenarios, and repeats the point in its conclusion. But demonstrating that a result holds across a range of scenarios is exactly what the missing sensitivity analysis does, and exactly what the cited manual requires be reported at this scale. The scenarios may well have been run. Their results are not shown.

    And the report clearly knows how to show them. Elsewhere in the same document, the ridership forecast comes with multiple scenarios and a published band around it. The economy-wide GDP figure rests on nearly a hundred separate model runs with the assumptions varied. Between a tested input and a tested output sits the largest single number in the report, presented as a single column of point estimates.

    The Optimism Adjustment

    A top-up the manual requires, and the report does not mention

    Early cost estimates for big infrastructure projects are, as a matter of record, too low. Not occasionally — routinely. The Metrolinx manual is explicit about the evidence behind this: in an international sample of 258 rail projects, ninety per cent were undercosted, by an average of forty-five per cent.

    The manual’s response is a mandatory top-up applied to the construction cost when it is compared with benefits, over and above whatever contingency is already in the estimate. The size of the top-up depends on how far the design has progressed. At the earliest stage — nought to ten per cent designed — it is 64 per cent.

    ALTO’s cost estimate is described in its own report as an AACE Class 5 estimate, which is the earliest and least developed class there is. Applied as the manual directs, a cost of $60 to $90 billion would enter the comparison at roughly $98 to $148 billion, before any comparison with benefits is attempted. That range is our own arithmetic on ALTO’s published estimate at the manual’s stated uplift; ALTO publishes no uplifted figure.

    The report applies no such adjustment and does not mention the concept. It is worth noting where this reasoning comes from: the manual grounds the adjustment in the research on transport megaproject cost overruns that this Initiative has drawn on since its first publication. That reasoning is already embedded in the appraisal manual ALTO chose to cite.

    The Central Inversion

    Too early to divide, but not too early to multiply

    The report declines to publish a benefit-cost ratio — benefits divided by costs, the single number a reader would most want. Its stated reason is that the cost estimate is too immature to support one.

    Under the framework ALTO cites, that reasoning runs backwards. The manual sets out what is required at each stage of a project’s life. At the earliest stage, the very stage ALTO is at, the requirement is a single line: conduct sensitivity testing to understand the key drivers and the level of uncertainty in each option.

    Early-stage uncertainty is not an exemption from testing. It is the reason testing is required. The report treats it the other way round: immaturity on the cost side is given as grounds for publishing nothing, while single-point figures are published on the benefit side of the same ledger. The same uncertainty is treated as decisive for one number and immaterial for the other.

    And a business case for this corridor has already done it. In December 2021 the Joint Project Office — VIA Rail and the Canada Infrastructure Bank — published a benefit-cost ratio for High Frequency Rail, the cheaper predecessor to ALTO, at a comparable stage of development: about 0.13, or roughly 0.4 on an expanded basis counting fare revenue and agglomeration as benefits. It published a net present value of minus $21.1 billion and a thirty-year public subsidy of $37.1 to $42.2 billion alongside it. Its economic parameters were drawn from Metrolinx and Ministère des Transports du Québec guidance — the same two sources ALTO cites. Immaturity did not prevent a ratio then. The companion explainer Hours Are Not Dollars sets out those figures in full, including why 0.13 rather than 0.4 is the anchor.

    A related point arises elsewhere in the report. In explaining why one set of results is excluded from the welfare account, it refers to those results as therefore not being included in the benefit-cost ratio — speaking of it as a thing with a settled boundary about what enters it. One page says a meaningful ratio cannot yet be produced. Another treats the ratio as already drawn up. The two are difficult to read together, and the report does not reconcile them.

    Limits of This Analysis

    What this brief does not say

    Stated here rather than left for others to find.

    On the analysis

    The rate is not wrong3.5 per cent is a defensible choice, used by the United Kingdom Treasury and by Metrolinx, and well supported for long-horizon public investment. This brief does not argue that ALTO’s rate is too low or too high.
    Metrolinx does not bind ALTOA provincial agency’s manual has no legal force over a federal Crown corporation. The argument is about the coherence of a citation, not about jurisdiction.
    One choice runs in ALTO’s favourThe 3.5 per cent rate is applied flat across sixty years. The UK Treasury, whose Social Time Preference Rate this figure matches, steps its rate down to 3.0 per cent after year 30. Applying that schedule would have made ALTO’s benefit total larger, not smaller.
    One cited source was not reviewedGuidance from the Ministère des Transports du Québec is cited separately for the value of time. The Initiative has not reviewed it and takes no position on what it requires.

    On the report and its source

    The report does apply conservatism in placesAccident reductions are capped after twenty years, and car emission factors are assumed to improve to 2050, which the report notes limits the emissions benefit. These are the two smallest monetised lines. No equivalent constraint is disclosed for travel time, which is 78 per cent of the total.
    The manual itself is datedMetrolinx said in 2021 that a revised version with updated values would follow in 2022. Five years on, it has not. That is a limitation of the source document, not a fault of ALTO’s — but a reader assessing where a federal appraisal input came from is entitled to know it.
    Which figures are whoseEvery figure attributed to ALTO, Metrolinx, the Joint Project Office, HM Treasury or Statistics Canada is quoted from the sources listed below and can be checked there. Three figures are our own arithmetic and are marked as such where they appear: the $98 to $148 billion uplifted capital range, the $21.40 inflation-escalated value of time, and the five per cent effect of the declining Green Book schedule. Where the report does not state something, we say so rather than inferring it, and we make no claim about why any requirement was or was not carried across.
    This is a public report, not a formal submissionA business case submitted to Cabinet in 2029 may well contain material this document does not. The claims examined here are the claims ALTO has chosen to put in public.
    What Would Settle It

    Two questions ALTO can answer without releasing a model

    Both are answerable from work ALTO has already done. Neither requires disclosure of a model, cooperation from staff, or agreement about what the correct discount rate for a national railway ought to be.

    1. Was the calculation ever run at a rate other than 3.5 per cent?

    And if so, what were the results? A negative answer is itself informative — it would mean the required test was never performed. An affirmative answer is the sensitivity table the report does not contain.

    2. Which parts of the cited guidance were applied, and which were departed from?

    The Metrolinx document requires that any variation from its parameters be agreed and clearly justified. The report records no variations at all — while, on the evidence above, departing from several.

    Where Things Stand · August 2026

    Summary ledger

    Measured against the requirements of the manual ALTO names as its authority:

    Carried across
    The 3.5 per cent discount rate, correctly cited to the manual.
    Carried across
    The single blended value of time, expressly justified by reference to the manual.
    Partial
    The thirty-year cap on benefit growth: applied to accident and emissions lines, not stated for travel time, which is 78 per cent of the benefits.
    Partial
    A single price year throughout: the appraisal is in 2024 dollars, the GDP result in 2019 dollars.
    Left behind
    Discount rate sensitivity test at 2.5 per cent.
    Left behind
    Value of time sensitivity test at 0.75 per cent real growth.
    Left behind
    Range analysis of costs and assumptions, reported with a confidence level.
    Left behind
    The probability that benefits exceed costs, and the benefit-cost ratio itself.
    Left behind
    The standard set of performance indicators: net present value, benefit-cost ratio, capital utilisation, return on investment, internal rate of return.
    Left behind
    The optimism-bias top-up on construction costs, 64 per cent at this level of design — not applied and not mentioned.
    Left behind
    The lower end of the range, on figures the report itself labels an upper estimate.

    ALTO names an appraisal manual twice — once for its discount rate, once to justify a single blended value of time — and leaves behind the testing, the ranges, the optimism adjustment and the benefit-cost reporting that the same manual attaches to those figures at this project’s scale. What remains is a column of numbers labelled an upper estimate whose lower estimate is never shown, resting on parameters presented as facts rather than as selections, in a report that declines to divide that column by the cost while describing the benefits as holding across a wide range of scenarios.

    Every document relied on here is public. Nothing in this analysis requires access to ALTO’s models, cooperation from its staff, or a view on what the correct discount rate for a national railway ought to be.

  • Winter, Ice and the Weather Envelope

    ALTO HSR Citizen Research · Technical Brief

    Wind, Ice & the Weather Envelope

    Winter snow is not the only weather that shapes a high-speed railway. The faster a line is built to run, the more it must spend to stay reliable when the weather turns — and the government’s own record shows this question was raised, and left unanswered.

    Winter Weather De-Icing & the Karst Economics
    ⚠ On the record: the speed-in-winter question was answered in 2020

    An October 2020 Ministerial Briefing, released under the Access to Information Act, found that the government’s advisers could not identify any high-speed rail system that operates at 300 km/h in −30 °C conditions. The only cold-climate comparator they identified — China’s Harbin–Dalian line — reduces speed from 350 km/h to 250 km/h in winter. The finding was briefed to ministers more than four years before the project was announced. ATIA A-2024-004

    In June 2026, the tabled government answer to a Parliamentary question on winter-weather readiness confirmed that, “at this point in the design process,” Alto has not commissioned a comparative freezing-rain, snow, or ice assessment, nor a full winter-weather cost analysis, and that its freezing-rain reliability targets are “currently in development.” Sessional Paper 8555-451-1191

    Why this brief

    High-speed rail runs successfully in some of the world’s harshest weather — but never for free, and never without operating rules that slow or stop trains when conditions demand it. Every mature operator lives inside a “weather envelope”: the range of conditions in which full-speed service is safe. Crosswinds, tornadoes, freezing rain, and heat all sit at its edges.

    Because wind forces grow with the square of speed, and because cold, ice, and heat mitigation all cost more the faster and longer the line, the decisive question is not whether high-speed rail can run here. It is how fast the line should be designed to run, and whether the weather-hardening that speed requires has been counted. This brief draws on published engineering research, the operating experience of networks in Japan, China, and Europe, and the project’s own record released under the Access to Information Act. It is not an argument against high-speed rail.

    On the Record

    The question was examined internally — and never reconciled in public

    This is not only an inference from international experience. Documents released under the Access to Information Act show the federal government examined exactly this question years before the project was announced — and in June 2026 the government confirmed to Parliament that Alto has not yet commissioned either a comparative winter-weather assessment or a full winter-weather cost analysis.

    What is advertisedWhat the record shows
    “300 km/h or more. Even in winter.” Alto’s public promotion assumes consistent 300 km/h running, and the advertised journey times depend on it. The October 2020 Ministerial Briefing found no HSR system was identified that operates at 300 km/h in −30 °C. The only cold-climate comparator, Harbin–Dalian, reduces 350 → 250 km/h in winter.
    Reliability is “designed into every kilometre,” with “heated switches to de-icing systems.” The June 2026 answer confirms that, “at this point in the design process,” Alto has not commissioned a comparative freezing-rain / snow / ice assessment or a full winter-weather cost analysis; reliability targets for freezing-rain conditions are “currently in development.”
    A 300 km/h specification is presented as the project’s baseline. The May 2025 Corporate Plan contains no cold-climate operating standard, and the 2020 finding has never been publicly addressed.

    Two further items on the record bear directly on the speed choice. First, the procurement was structured as a speed comparison: each of the three bidders was required to submit both an enhanced-conventional option (up to 200 km/h) and a high-speed option (300+ km/h). A slower, cheaper design was therefore a live, formally-evaluated alternative — not a hypothetical. Second, the 2011 EcoTrain feasibility study of a Windsor–Quebec City high-speed service concluded that the full Québec City–Windsor corridor would not be financially viable on a standalone commercial basis and would require substantial public funding — though it found the Montréal–Ottawa–Toronto segment could generate net economic benefit. When a corridor’s commercial case is that fragile, avoidable cost — including over-specifying speed and the weather-hardening it demands — matters more, not less.

    Why this matters for speed and cost

    The gap is now a matter of record. The government’s own briefing established that 300 km/h has not been demonstrated in extreme cold, and that the nearest cold-climate line runs slower in winter — yet the advertised journey times assume full speed year-round, and Alto has confirmed it has not commissioned the comparative assessment or full winter-weather cost analysis that would test the assumption. A lower-speed option was on the table and formally costed. That is precisely the speed-and-cost question this brief is about, and it remains open.

    Wind & Crosswind

    The everyday wind risk is overturning — and it scales with speed

    For a high-speed train, the routine wind hazard is not a dramatic storm but a strong steady crosswind catching the train side-on. Aerodynamic side and lift forces rise with the square of the combined train-and-wind speed, so a lighter modern trainset at line speed becomes sensitive to winds that would barely trouble a slower, heavier train. The failure mode that governs design is overturning, not wheel-climb derailment.

    The threshold is closer than it looks

    In one published dynamic simulation, a high-speed vehicle running at 300 km/h overturned when the crosswind reached roughly 24 m/s (about 86 km/h) — a strong gale, but far short of tornado strength. Chinese railway practice treats an overturning coefficient above 0.8 as the danger threshold, and the overturning coefficient in these conditions typically runs about twice the derailment coefficient. Crosswind-induced overturning has been blamed for derailments in China, Japan, Belgium, and Switzerland.

    The speed lever

    Because the force grows with the square of speed, a line designed for 300 km/h is markedly more wind-sensitive than one designed for, say, 250. A higher design speed means the safe crosswind threshold is crossed more often — so a faster line needs more wind fencing, more sensor coverage, and lives with more frequent speed restrictions. Exposure is also geometry: viaducts and high embankments are the danger zones, cuttings and tunnels are sheltered, and running fast across open, elevated country is the most demanding combination of all.

    The mitigation is well proven — anemometer networks feeding automatic speed control, backed by physical wind barriers on exposed stretches. After a December 2005 derailment on the Uetsu Line, Japan’s JR East revised wind-based speed limits system-wide and installed windbreak fences and a strong-wind warning system; porous barriers can cut a train’s crosswind response by around a quarter. China’s Lanzhou–Xinjiang line runs long wind-fenced sections through the Gobi’s windy zones. None of it is free, and the bill rises with the speed being protected.

    Tornadoes

    Rare, extreme, and hard to see coming

    Tornadoes break the crosswind playbook, and it is worth being precise about why: they are managed by avoidance, not by building a train that can survive one. An EF2 tornado carries winds well above 180 km/h and EF3 higher still — far beyond the ~85–100 km/h band where overturning becomes likely. No practical trainset or wind fence keeps a train upright through a direct strike at speed.

    Detection is the hard part

    Fixed anemometer grids are calibrated for the prevailing winds that blow along the line. A tornado is a narrow, fast-moving, erratic feature that a line-side sensor network may never register before a train is in it — the opposite of the seismic case, where Japan’s earthquake system gets seconds of warning and automatically cuts power and brakes. Even a near miss throws trees and debris onto the alignment.

    The corridor sits in Canada’s tornado belt

    Most Ontario tornadoes are concentrated in a narrow corridor from Windsor to Ottawa and into parts of southern Quebec — the geography the proposed line traverses. Tornadoes up to F4 have been documented in the region; the 2018 National Capital outbreak produced a high-end EF3, and Canada records an estimated 230 tornadoes a year. The mainstream response is warning-triggered service suspension — hold the trains — not survivability engineering.

    In proportion, the tornado question is a genuine but low-frequency tail risk managed through hold procedures — the more dramatic hazard, but the smaller line item. Routine crosswind exposure, which shows up as everyday speed restrictions, is the larger and more quantifiable one.

    Freezing Rain

    Freezing rain is an electrical problem as much as a track problem

    Snow can be ploughed and blown clear. Freezing rain cannot — and its most serious target on an electrified line is not the rail but the overhead wire, the single power path for the whole train. Ice on the contact wire degrades the pantograph’s ability to collect current; it can flash over insulators, set the wire into large-amplitude “galloping” oscillations, and cause arcing — in severe cases, disconnection. Freezing rain is a recognised cause of equipment malfunction and delay wherever winters hover near 0 °C — precisely the St. Lawrence Valley profile documented in our Winter Weather analysis.

    The mitigation is real, proven, and continuous — which is another way of saying it is a permanent cost line. France’s SNCF illustrates the toolkit: electric switch heaters, resistive heating circuits that keep catenary above freezing, a fleet of de-icing “scraper” locomotives, and a hydrophobic anti-icing lubricant on the contact wire. China’s purpose-built cold line pairs catenary de-icing with turnout snow-melting and a dedicated snow-and-ice monitoring system. Freezing rain is beaten by equipment plus surveillance plus standing procedures — all carrying capital and maintenance cost that scales with the length of exposed line.

    And a second question: which de-icing method?

    Mitigating ice raises a choice with its own consequences. Alto’s own winter-operations material lists chemical de-icing using “glycol- or saline-based solutions,” while its June 2026 Parliamentary answer instead illustrates winter mitigation with electric methods — ice-breaking equipment and running high current through the catenary to melt ice. Glycol and chloride de-icers carry serious environmental constraints over the Frontenac Arch and Napanee karst, where contaminants can reach the aquifer before any collection point exists.

    As our De-Icing analysis sets out, that pushes the corridor toward electric heating as the primary de-icing technology on sensitive sections — effective, but a permanent energy and cost load. The freezing-rain problem and the environmental problem point at the same answer, and the same bill.

    Heat & Water

    The other ends of the envelope

    Summer heat and rail buckling

    Continuously welded rail expands in extreme heat and can buckle (“sun kink”). Operators manage this with real-time rail-temperature monitoring, heat-related speed-limit orders, and — in some networks — spraying track with water. A corridor with a >70 °C annual temperature swing, like the cold-climate reference lines, must design for both extremes at once.

    Heavy rain and flooding

    Intense rainfall drives washouts, embankment and slope failure, and landslides — which is why high-speed operators monitor rainfall and river levels alongside wind, and impose speed controls or shutdowns when thresholds are crossed.

    What It Costs

    Weather-proof is achievable — the reference projects show the price tag

    The strongest evidence that severe-weather high-speed rail works is also the strongest evidence that it is expensive and route-specific. Two reference cases are instructive.

    China · Harbin–DalianJapan · Shinkansen
    The world’s first alpine high-speed line runs through a −40 °C to +40 °C range. To beat frost heave, 70% of the line was built on viaduct and about 20% of the at-grade track was rebuilt before opening. Final cost ran roughly 25% over budget. It historically dropped to 250 km/h in winter and, even after resolving frost heave, runs a unified 300 km/h year-round — still below its 350 km/h design speed. Snow-related cancellations were cut from a 1976 peak of 635 to essentially zero since 1994 — but only through sprinkler systems, slab track, snow-removal teams, and undercarriage sensors, and delays of 10–20 minutes still occur in snow. A high-speed train has derailed in blizzard conditions (Akita, 2013, no injuries). Reliability is engineered; it is not free.

    The lesson is not that weather makes high-speed rail impossible — it plainly does not. It is that weather resilience is a design choice priced in both dollars and speed: a purpose-built cold line still ran over budget, and still ran slower in winter until the problems were solved. The faster the promised service, the steeper both penalties climb. That is why weather belongs inside the speed-and-cost decision, and why those figures should be visible in a public business case.

    And the cost-risk itself is unquantified

    The un-commissioned winter-weather cost analysis sits inside a capital estimate the government describes as preliminary. Asked in June 2026 for its estimate of the risk of Alto exceeding $90 billion, the government replied that it has no quantitative estimate of that likelihood, or of any overrun amount, because the cited $60–90 billion is “a preliminary, high-level planning range and not a final project budget.” Un-costed weather-hardening therefore sits within a capital range whose own overrun risk has not been quantified.

    Where things stand · July 2026

    The winter-weather accountability ledger

    Measured against what a defensible 300 km/h “even in winter” claim would require:

    Not shown
    A precedent for 300 km/h operation in extreme cold. The government’s own advisers could not identify one in October 2020; the nearest comparator reduces to 250 km/h in winter.
    Not commissioned
    A comparative freezing-rain / snow / ice assessment. Alto states it has not commissioned one “at this point in the design process.”
    Not commissioned
    A full winter-weather cost analysis. Alto states it has not commissioned one; winter costs are to be folded into operating-cost estimates instead.
    Absent
    A cold-climate operating standard. The May 2025 Corporate Plan contains none.
    In development
    Freezing-rain reliability targets. Stated to be still in development.
    On record
    A lower-speed alternative. The procurement required an enhanced-conventional (up to 200 km/h) option alongside the high-speed one — a slower, cheaper design was formally evaluated.

    Questions for the process

    What design speed is being committed to, and how much of the capital cost is weather-hardening for that speed — wind fencing, catenary de-icing, switch and pantograph heating?
    What weather-related speed-restriction and service-suspension frequency sits behind the advertised journey times — would passengers actually see 300 km/h as often as promised?
    Given that a lower-speed option was formally evaluated, has the speed-versus-weather-cost trade-off been quantified and published — and why was the higher speed chosen?
    Since the comparative winter-weather assessment and full cost analysis have not yet been commissioned, when will they be undertaken and published — and will that happen before design speed and cost decisions are locked in?
    Have the severe-weather cost overruns seen on comparable projects (Harbin–Dalian, ~25% over budget) been reflected in contingency and risk provisions?

    By Their Own Standard

    Build Canada’s case for high-speed rail, measured against the megaproject method the memo itself invokes.

    ALTO HSR Citizen Research Initiative · Methodology Brief · Published June 2026 · ALTO consultation closed April 24, 2026
    ⚠ The Document Under Review

    Build Canada’s February 24, 2025 memo, Let’s Show the World How Canada Builds, was published one week after the federal high-speed rail announcement. It endorses high-speed rail in the Toronto–Quebec City corridor and names ALTO directly, while contesting only how the project is delivered — not whether the demand exists or whether the benefit–cost case closes. This brief takes the memo’s argument on its own terms, and holds it to the analytical standard the memo itself sets. Build Canada · original memo

    Critical Finding

    The memo reaches for exactly the right tools. It quotes Bent Flyvbjerg, the leading scholar of megaproject cost overruns; it calls for reference-class benchmarking against comparable lines; it demands contingency discipline; and it warns that without these, ALTO becomes another HS2 or California High-Speed Rail. On the diagnosis, the Initiative agrees.

    The memo then abandons each principle at the moment it matters. It caps contingency at the level that, on its own logic, guarantees overrun. It imports foreign unit costs from a reference class that is not comparable. And it promises true high-speed rail at a unit cost that, in Canadian conditions, only high-performance rail can plausibly reach. Applied honestly, the memo’s own method points away from its conclusion.

    The evidence produced since the announcement confirms the diagnosis the memo made and refutes the targets it set. The corridor is still being fundamentally re-routed in the project’s second year; the friction the memo proposed to legislate away has surfaced exactly where the method predicts. The case for caution on ALTO does not require rejecting Build Canada’s framework. It requires applying it.

    The Argument’s Shape

    What the memo contests, and what it does not

    The memo’s argument has a particular structure. It accepts ALTO’s entire benefit case without examination — 40 per cent of the economy, 18 million people connected, up to $35 billion a year in added GDP, travel times halved — and contests only whether the project can be built cheaply and quickly. Every one of those headline figures is the proponent’s own number, repeated approvingly. The memo never asks whether the ridership exists to fill the trains, or whether the benefits exceed the costs.

    It asks one question: can Canada build it the way France, Spain, and Japan did? To answer, it reaches for the right instruments — Flyvbjerg’s work on megaproject overruns, reference-class benchmarking, contingency discipline, and the cautionary record of HS2 and California. That choice of tools is what makes the memo worth engaging seriously, and what makes its conclusion fail. The same tools, applied with honest inputs, do not support the case the memo builds on them.

    Held To Its Own Standard

    Three flaws, by the memo’s own method

    On three load-bearing claims, the memo prescribes the opposite of what the method it cites requires. The left column states the memo’s own prescription; the right column applies the memo’s own standard to it.

    What the memo prescribesHeld to its own standard
    1. Cap contingency, including inflation, at 10 per cent. Presented as following global best practice, alongside meticulous benchmarking against French and Japanese lines.Reference-class forecasting — the very method the memo invokes — requires a larger uplift the less design is complete, because the unknowns are still unpriced. The memo itself concedes Canadian projects sit at 1–10 per cent design maturity. At that maturity, the honest uplift is routinely 40 per cent or more; a 10 per cent cap is defensible only near design completion. The prescription specifies the precise conditions under which budgets break, and calls it discipline.
    Verdict:Self-contradictory
    2. $25–40M per km; a corridor for under $50B; payback within two years. Drawn from the cost record of France, Spain, and Japan.A reference class works only if the cases are comparable, and these are not. The cited figures come from older lines, on flatter and cheaper terrain, in earlier cost eras, with no adjustment for what this corridor crosses: the granite of the Canadian Shield, the Frontenac Arch, the wetland and karst of eastern Ontario, and dense urban approaches at both ends. Importing an unadjusted foreign unit cost is exactly the non-analogous-reference-class error Flyvbjerg’s method exists to catch — committed in the section that cites him. The Initiative’s complexity-adjusted estimate runs several times higher, with a central benefit–cost ratio far below the break-even the memo treats as obvious.
    Verdict:Wrong reference class
    3. True high-speed rail at that same unit cost. Dedicated track, full electrification, grade separation, 300 km/h — delivered for $25–40M per km.In Canadian conditions, $25–40M per km is not a high-speed-rail figure at all. It is roughly the cost of a high-performance rail upgrade — incremental improvement of existing alignments, the option the memo dismisses in a single line. The memo promises high-speed performance at high-performance-rail prices. The headline product and the headline number belong to two different projects; you cannot buy the performance of one at the price of the other.
    Verdict:HSR promise, HPR price
    $25–40M
    per km — the memo’s claimed unit cost, from France / Spain / Japan
    Build Canada memo
    ≈ $143B
    reference-class capital for the corridor delivered as high-speed rail
    CRI reference-class analysis
    ≈ 0.06
    central benefit–cost ratio — against the memo’s implied two-year payback
    CRI NPV / BCR matrix

    “Payback in two years” implies a project that returns many times its capital. The reference-class evidence points to one that returns a small fraction of it. The gap between the memo’s number and the comparable record is not a rounding difference; it is the entire argument.

    What Has Happened Since

    The diagnosis confirmed, the targets refuted

    More than a year on, events have tested the memo’s promises against reality. They vindicate its diagnosis of Canadian megaproject failure and dismantle the targets it set against that diagnosis.

    A corridor still being re-routed in year two

    The memo set a target of a high-value section carrying passengers within five years, on standardized, locked-in designs, at 10 per cent contingency. Yet the corridor is still being fundamentally re-aligned — a southern-corridor study, a conditional new station at Kingston, an alignment still unchosen between north and south. That is direct evidence of the planning immaturity the memo flagged on its first page — and it makes the memo’s own targets incoherent. You cannot run trains in five years on frozen designs while you are still deciding where the line goes.

    Friction exactly where the method predicts

    The memo’s prescriptions — sever environmental review from planning, legislate automatic approvals, reduce municipalities to suggesting where infrastructure is placed rather than whether — were aimed at the precise constraints this corridor turns out to be full of: two UNESCO designations, species at risk, organized community opposition, and rural-character concerns that public consultation surfaced in volume. The Initiative’s Community Friction Index has risen from 43 to 54 since consultation began and is projected to climb further. The memo’s answer to friction is not to resolve it but to override it — and on this corridor, that is neither lawful nor likely.

    The memo’s own number makes the HPR case

    The memo dismisses improving existing rail as insufficient, insisting dedicated high-speed track is the only way. But its own affordability figure, $25–40M per km, is a high-performance-rail number — and the consultation recorded clear public appetite for improving VIA service first and preserving existing Kingston and eastern-Ontario connections. Strip the rhetoric and the memo makes the affordability case for the alternative it rejects.

    Conclusion

    The antidote that recreates the disease

    The memo casts ALTO as Canada’s escape from the HS2 and California failures. Trace its logic, though, and the resemblance runs the other way. “We will build it cheaply and quickly like France and Japan — just cap the contingency and clear the obstacles” is not the cure for optimism bias. It is the textbook expression of it, almost word for word how California began.

    The memo’s real service is that it concedes the entire framework. Flyvbjerg, reference classes, contingency discipline, planning maturity: take those tools, feed them honest inputs, and the conclusion does not survive. The case for caution on ALTO does not require rejecting Build Canada’s method — it requires applying it. Done honestly, it points not toward a sprint to high-speed rail at imported prices, but toward a high-performance upgrade of the corridor Canadians actually use, at a cost the country can defend.

    Where The Method Lands

    Summary ledger

    The memo measured against the standard it sets for itself:

    Sound
    Diagnosis — planning-maturity gap. Correctly identifies that Canadian projects enter procurement at 1–10% design versus 30–70% abroad.
    Sound
    Delivery authority. Rightly prefers a strong, technically competent public authority over dependence on a consultant consortium.
    Sound
    Reference-class benchmarking. Rightly names it as the antidote to optimism bias.
    Violated
    10% contingency cap prescribed at 1–10% design maturity — manufactures the overrun the memo warns against.
    Violated
    $25–40M/km imported from non-comparable lines without adjustment for terrain, era, or urban approaches.
    Violated
    HSR promised at HPR price. The headline product and the headline cost belong to two different projects.
    Violated
    Override of environmental review and municipal consent — aimed squarely at the corridor’s real, documented constraints.
    Refuted by events
    Five-year passenger target on frozen designs — incompatible with a corridor still being re-routed in the project’s second year.

    The memo is at its strongest where it agrees with the Initiative — on method. It is at its weakest where it abandons that method to reach a predetermined answer. Applied honestly, Build Canada’s own framework makes the case for high-performance-rail realism, not for a high-speed sprint at imported prices.

  • Norway-review

    What a Norwegian-Style Review Would Ask of ALTO

    Norway has spent twenty-five years subjecting every major public investment to mandatory independent review at two decision gates. Measured against that standard, ALTO’s $75 billion figure has not yet cleared the first gate — and the conceptual choice between the corridor alternatives has never been independently reviewed at all.

    ALTO HSR Citizen Research Initiative · International Precedent Brief · Published May 2026
    ⚠ What This Brief Examines

    Since 2000, Norway has run a mandatory two-gate external Quality Assurance scheme — QA1 on the choice of concept, QA2 on cost estimates before funding — under its Ministry of Finance, for every major public investment project.

    This brief sets out how the scheme works, what twenty-five years of evidence across roughly 160 reviewed projects shows about whether independent review improves cost discipline, and what that working institutional template implies for the ALTO corridor decision and for the High Performance Rail (HPR) alternative the Initiative has advocated.

    Headline Finding

    Twenty-five years of operating evidence shows that systematic external review materially improves cost discipline: roughly three-quarters of post-QA2 projects have been delivered within their parliamentary cost frame, against pre-QA cost overruns documented at 59 to 183 percent on Norwegian transport projects.

    ALTO’s published $75 billion cost figure is a concept-stage estimate that, by Norwegian standards, has been subjected to neither external concept-stage review (QA1) nor stochastic pre-budget cost validation (QA2). A federal investment of ALTO’s scale would unambiguously fall within mandatory independent review under any institutional design comparable to Norway’s.

    Section 1 · Origin and Purpose

    A scheme built to filter flawed investments

    Norway’s Quality Assurance scheme — kvalitetssikringsordningen, rendered in English as QA1 and QA2 — was established in 2000 by the Ministry of Finance in response to a recurring pattern of cost overruns and weak strategic justification on megaprojects through the 1980s and 1990s. It was built with two objectives: to avoid budget overruns on projects already under construction, and to filter out flawed investment cases that should not have been started at all.

    In its initial form (2000–2005) the scheme was QA2 only — assurance of cost estimates immediately before parliamentary approval. From 2005, QA1 was added as an upstream gate covering the choice of conceptual solution itself, before a project enters preliminary design. The two-gate structure has been substantially unchanged since, with periodic recalibration through Ministry of Finance circulars; the current governing circular is R-108/23, superseded in part by R-108/25.

    The scheme is mandatory. It applies to all government investment projects above a threshold of roughly one billion Norwegian kroner — about CAD 130 million in 2026 terms — and about CAD 39 million for digitalisation projects. The petroleum sector is exempt; state enterprises such as Bane NOR, Nye veier and Statnett run parallel internal regimes that mirror the central scheme. Essentially every Norwegian federal infrastructure investment of comparable scale to ALTO would face mandatory external review at two decision points.

    Section 2 · The Two Review Gates

    One gate on the concept, one on the cost

    The scheme’s power lies in where it intervenes: once on whether the right concept has been chosen, and again on whether the cost presented to Parliament is honest. Each gate has a defined deliverable and a defined methodological standard.

    QA1 — Quality assurance of concept choice

    Performed before Cabinet decides to start a pre-project. The proponent must prepare a Conceptual Appraisal (KVU), and the external reviewer assesses whether the alternatives analysis is genuine — whether the do-nothing case and conceptually different options were evaluated rigorously, rather than treated as nominal foils to a predetermined preference. The recommendation goes to Cabinet on the public record.

    QA2 — Quality assurance of cost

    Performed before the project goes to Parliament for funding. Its core is stochastic cost estimation: not a single figure but a probability distribution, with the budgeted cost normally set at P85 and a P50 target committing the executing agency — because deterministic estimates are systematically skewed and under-assure against overrun.

    The KVU underlying a QA1 review must contain a defined set of elements, and the reviewer checks each:

    • A needs analysis identifying the underlying problem the project is intended to address.
    • A goals and objectives statement specifying the societal outcomes the project is meant to deliver.
    • A requirements analysis identifying functional and operational specifications.
    • An alternatives analysis covering at minimum the zero option (do nothing) plus at least two conceptually different alternatives.
    • A cost-benefit analysis covering each alternative.

    QA2 adds a forward-looking management challenge assessment of operational, procurement, scope and schedule risk, and produces a project-specific reduction list (kuttliste) — pre-identified scope items that can be removed during execution if costs trend toward the upper bound. This preserves flexibility within the parliamentary cost frame rather than requiring re-authorization for each overrun.

    Section 3 · Who Reviews, and How Independence Is Preserved

    The funding ministry picks the reviewer — not the proponent

    The reviewers are external private-sector consultants on a Ministry of Finance framework agreement. The current framework (September 2023) covers seven consortia — including Holte Consulting, Menon Economics, A-2 Norge, Dovre Group Consulting and the Institute of Transport Economics. Use of a pre-approved consortium is compulsory; ad hoc retention outside the framework is not permitted. Several features preserve independence:

    • The Ministry of Finance selects the reviewer — not the project-proposing ministry — removing the conflict that arises when a proponent can choose its own reviewer.
    • Pre-defined methodology. The reviewer follows requirements set in the Ministry circular and cannot redefine scope or renegotiate methodology with the proponent.
    • Conflict-of-interest restrictions. A consortium that did concept-stage advisory work on a project is generally precluded from reviewing the same project.
    • Public reporting. QA reports are public documents (with limited commercial redactions) and are catalogued by NTNU’s Concept Research Programme, which has tracked every review since 2000.

    The review itself is cheap relative to what it examines — typically a fraction of one percent of project capital cost — and is funded by the Ministry of Finance rather than charged against the project ministry.

    Section 4 · The Empirical Record

    Twenty-five years of evidence: review works

    NTNU’s Concept Research Programme has tracked the cost performance of every project subject to the scheme since 2000 — roughly 160 QA2 reviews and 60 QA1 reviews, a sample large enough to draw robust conclusions. The finding is consistent: post-QA2 Norwegian projects substantially out-perform international cost-overrun benchmarks.

    ~75%
    Of post-QA projects delivered within their parliamentary cost frame (Welde & Klakegg, 2022)
    59–183%
    Cost overruns on pre-QA Norwegian transport projects (Odeck, 2004)
    45%
    Mean rail cost overrun across 258 international projects (Flyvbjerg et al., 2003)

    A multi-country study of Scandinavian rail and road projects completed 2008–2022 (Love et al., 2025) concludes they are generally delivered “on cost, over time” — within approved budgets, though often behind schedule. The introduction of mandatory external QA materially compressed the cost-overrun distribution.

    The harder finding: front-end escalation persists

    The more nuanced result concerns the front-end — the period between QA1 and QA2. Even with mandatory concept review, average cost escalation between the two gates has run at about 40 percent (Welde & Odeck, 2017). As a project moves from concept to detailed pre-design, scope clarification reveals cost drivers the initial estimate missed; Norway’s Planning and Building Act, which gives municipalities significant influence over alignment and siting, is a documented contributor. In response, the Ministry introduced a continuous change-log requirement in 2019, tightened further in the 2025 circular.

    Implication for ALTO’s $75 billion

    ALTO’s published $75 billion is a pre-QA1-equivalent estimate. The Norwegian record predicts ~40 percent escalation through the equivalent pre-project phase — which alone would lift the figure to roughly $105 billion, before any of the further adjustments the Initiative’s reference-class analysis applies.

    Section 5 · Norway QA versus Canadian Practice

    The gap is structural, not incidental

    Set side by side with current Canadian federal practice, the differences are structural. The most consequential is at the concept gate: Canada has no equivalent of QA1 — no mandatory external review of conceptual alternatives before a project enters pre-design.

    FeatureNorway QA1 / QA2Canada (federal practice)
    Mandatory threshold≈ CAD 130M (NOK 1B); CAD 39M for ITNo threshold-triggered mandatory external QA
    Concept-stage external review (QA1)Required before Cabinet approves pre-projectInternal departmental review only; none mandatory
    Pre-funding external review (QA2)Required before Storting funding voteTreasury Board review; not external; not stochastic by default
    Cost basis for ParliamentP85 of probability distributionTypically a deterministic point estimate
    Reviewer selectionMinistry of Finance call-off against frameworkProposing department selects its own consultants
    Public availability of reportPublic document (with redactions)Generally not published; subject to ATIP
    Concept alternatives requiredZero option plus ≥ 2 different alternativesVariable; not standardised
    Track record≈160 reviews; ~75% on budgetNo comparable institutional record

    ALTO is a paradigmatic example of the gap. The conceptual choice between high-speed rail (ALTO), high-frequency rail (HFR, the 2021 Joint Project Office concept), and high-performance rail (HPR, the Initiative’s alternative) has never been the subject of structured external review. Under Norwegian rules, that comparison would be the literal substantive content of QA1 — and Cabinet could not authorize a pre-project on any one concept without first having the comparison externally reviewed.

    Section 6 · Application to the ALTO Decision

    Five things a Norwegian review would find

    Applying the Norway framework as an analytical lens to ALTO yields five specific findings.

    1

    The cost figure would not be acceptable to a Norwegian Parliament

    QA2 requires the parliamentary cost frame to be set at P85 of a stochastic distribution. ALTO’s $75 billion is a deterministic point estimate — not acceptable as a funding basis by Norwegian standards, however rigorously derived internally. The Initiative’s reference-class range ($143B central; $264B P97.5) is a conservative analogue of what QA2 would produce.

    2

    The conceptual-alternatives requirement has not been met

    QA1 requires the zero option plus at least two conceptually different alternatives. The comparison among ALTO, HFR and HPR has not been structured, has not been externally reviewed, and is not in public ALTO documentation. A QA1 reviewer would not have approved corridor selection on the documentation produced to date.

    3

    ALTO is the kind of investment QA1 exists to filter

    The Initiative’s iso-BCR analysis finds a benefit-cost ratio of about 0.11 at central reference-class parameters — roughly eleven cents of benefit per dollar invested. That is the textbook profile of a flawed investment case, precisely what QA1 was built in 2000 to flag for substantive reconsideration.

    4

    The HPR alternative warrants concept-stage review

    HPR — electrified passenger service along the Highway 401 corridor with freight relocated onto a parallel dedicated corridor — is a substantively different concept, developed to a level comparable to proponent-stage QA1 documentation. The next institutional step is an independent concept-stage review of all three alternatives before any final corridor selection.

    5

    An adapted Canadian framework is feasible and proven

    Norway is not unique — comparable schemes operate in the UK, the Netherlands and at the European Investment Bank. The absence of a Canadian equivalent is a gap in institutional design, not a settled choice, and the design work is substantially complete in the English-language academic literature.

    Section 7 · Recommendations

    Three steps, project-specific to institutional

    Three recommendations follow, ordered from immediately applicable to the ALTO decision through to broader federal investment governance.

    1. Independent concept-stage review of the three corridor alternatives. Before any final corridor selection, the Department of Finance should commission an external review of ALTO, HFR and HPR modelled on QA1 — conducted by a consortium not previously engaged on any of the three, against pre-defined methodology, with a public report tabled before the Cabinet decision on the preferred concept.
    2. Stochastic cost framing for any preferred concept. Whichever concept is chosen, the Treasury Board submission should rest on a probabilistic cost distribution, not a point estimate — with the parliamentary frame at P85, a P50 target committing the agency, and a documented reduction list. This is the QA2 standard and the minimum-acceptable framing for an investment of this scale.
    3. A Canadian QA scheme. Canada lacks a federal equivalent of QA1/QA2, and the absence is structural. The 2021 JPO Business Case for HFR — still unreleased, with the Initiative’s Access to Information request pending — would under Norwegian design have been a public QA1 deliverable. Establishing a Canadian analogue would address a weakness documented across multiple Auditor General reports.
    Where Things Stand

    A working template, and an unreviewed decision

    Norway has demonstrated, over twenty-five years and 160-odd projects, that mandatory independent review at the concept and cost gates materially improves how major public investments perform. Canada has no equivalent — and ALTO, a federal investment of paradigmatic scale and policy importance, is advancing toward corridor selection without its conceptual choice having been independently reviewed, and on a deterministic cost figure that by Norwegian standards could not anchor a funding vote. The template exists; the decision has not yet been tested against it.

    Reading the Complexity

    How hard is the ALTO corridor to build — and why the answer decides whether its cost forecast can be trusted?

    ALTO HSR Citizen Research Initiative · Engineering Methodology Brief · Published May 2026
    ◆ Engineering-Complexity Methodology

    Cost forecasts for major rail projects are usually defended by comparison: the proponent points to a built line elsewhere, cites its per-kilometre cost, and applies it here. The comparison only holds if the two corridors are genuinely alike in how demanding they are to build. Most of the time, that question is never asked explicitly.

    This brief sets out a way to ask it. A ten-dimension rubric scores the engineering complexity of any high-speed corridor on a common 100-point scale, so that a proposed project can be placed against a worldwide database of built and under-construction lines. The point is not to produce a single number, but to make the comparator-selection step — the step where cost forecasts quietly succeed or fail — auditable.

    Critical Finding

    Scored against the rubric, the ALTO corridor reaches a composite of 82 out of 100 — in the Extreme band (81–100), and the highest of fourteen corridors in the worldwide reference database, seven points above the next-highest (California HSR, 75). No corridor at a comparable score has finished construction. ALTO therefore sits outside the range for which directly comparable delivery precedent exists.

    This matters for one reason above all: under reference-class forecasting, a project without a dimensionally matched precedent cannot be reliably costed from international benchmarks. A forecast built by borrowing the per-kilometre cost of a European or East Asian line scoring in the 40s or 50s will systematically understate what an Extreme-band corridor should be expected to cost.

    The Framework

    Ten dimensions, one hundred points

    The rubric scores a corridor on ten dimensions, grouped into four natural clusters: the ground and climate the corridor must cross (subgrade, bedrock, hydrology, climate); the geometry and hazard of the terrain (topographic relief, seismic and geohazard exposure); the environment and community it encounters (ecological footprint, heritage and Indigenous-rights constraints); and the corridor as a delivery and integration project (land acquisition, urban engineering content).

    Each dimension carries a weight reflecting its typical role in driving capital-cost dispersion across the reference class. Four cost-dominant dimensions — bedrock, climate, topography, and urban engineering — carry the maximum weight of 15 each. Subgrade and hydrology carry 10. The remaining four carry 5. The weights sum to 100, so the composite reads directly as a score out of 100. Each dimension is then scored on a granular scale up to its weight, against five descriptor levels: Minimal, Low, Moderate, High, and Extreme.

    20–60
    Low to Moderate — routine to standard HSR engineering
    most commissioned European and East Asian lines
    61–80
    High — multiple elevated dimensions; reference-class forecasting essential
    wide cost dispersion, overrun risk absent strong governance
    81–100
    Extreme — frontier engineering on several dimensions at once
    few or no directly comparable precedents

    The rubric reports two composites that answer different questions. The Peak Severity composite sums the granular scores, treating a dimension as fully present wherever its worst severity appears on the alignment — it characterises the engineering capability the corridor must provide at its most demanding locations. The Exposure-Adjusted composite scales each dimension by the fraction of corridor length at which that peak severity is actually present — it characterises the aggregate engineering burden spread across the whole route. Both are reported, because both bear on cost and schedule.

    Why this matters

    The rubric’s primary purpose is to discipline comparator selection. The standard failure mode in infrastructure forecasting, identified in the reference-class literature, is anchoring a forecast on favourable comparators while omitting the corridors whose complexity profile actually matches the proposed project. Explicit scoring against ten dimensions makes that selection step visible and checkable — only corridors with a similar dimensional profile are admitted to the reference class.

    The Application · ALTO

    The ALTO corridor scores 82 — Extreme

    Applied to the proposed ALTO corridor, the rubric returns a Peak Severity composite of 82 out of 100. The complexity is not attributable to any single factor; it arises from the simultaneous presence of multiple elevated dimensions across the ground, climate, environment, and land-acquisition clusters — the rubric’s definition of frontier engineering. Three dimensions reach their maximum, and two more sit at granular “High-plus” levels between the High and Extreme descriptors.

    ALTO Engineering Complexity Profile — Peak Severity, score / weight
    D1 Subgrade & soil — Leda clay
    10/10Extreme
    D2 Bedrock & excavation — Shield / karst

    D8 Heritage & Indigenous-rights

    D9 Corridor integration & land — greenfield
    5/5Extreme
    D10 Urban engineering content
    9/15Moderate
    Composite 82 / 100 — Extreme band (81–100). Three dimensions at maximum (subgrade, ecological, greenfield integration); two at High-plus (bedrock, climate). Bars show score as a fraction of each dimension’s weight.

    The two maximum scores that most distinguish ALTO are the subgrade dimension (10/10) and the greenfield land-acquisition dimension (5/5). The corridor traverses extensive Champlain Sea sensitive marine clay — Leda clay — across the Ottawa and St. Lawrence lowlands, a class named explicitly in the rubric’s top descriptor and associated with documented historical quick-clay failures. And the southern alignment is predominantly greenfield through actively farmed land, with property interests expected to number in the tens of thousands. The ecological dimension also scores at maximum: federally listed endangered species with designated critical habitat, a UNESCO biosphere reserve traversal, and significant wetland complexes.

    An interaction the score does not capture

    The composite treats dimensions as independent, but one coupling on ALTO deserves explicit attention: the interaction of maximum subgrade sensitivity (10/10) with elevated geohazard exposure (4/5). Ground-improvement works in sensitive clay can themselves destabilise marginally stable slopes — a failure mode with Canadian precedent. This is not reflected in any linear composite and should be treated as an explicit risk-register item, not a footnote.

    The Comparison

    Highest of fourteen corridors — and alone in the Extreme band

    Ranked against the worldwide database, ALTO occupies the top position by composite engineering complexity, and is the only corridor of the fourteen to fall in the Extreme band. The seven-point gap to California HSR crosses the High–Extreme boundary — a more substantive difference than the raw number suggests, because it marks the line beyond which directly comparable delivery precedent runs out.

    CorridorCompositeBand

    Madrid–Sevilla AVE (1992)50Moderate

    ALTO (proposed)82Extreme
    Selected corridors from the fourteen-corridor reference class. Full thirteen-corridor table in CAPEX Note 2.

    The comparison also shows why no single line is a clean match. California HSR’s complexity concentrates on seismic, topographic, and urban dimensions — factors well understood in California practice — but it does not face ALTO’s maximum subgrade and greenfield-integration scores. Harbin–Dalian is the nearest cold-climate reference, but it did not encounter sensitive marine clay. Ostlänken, in Sweden, is the closest analogue on ground conditions and climate, sharing the sensitive-clay and shield-bedrock profile — but not ALTO’s Extreme ecological footprint or the cold-climate severity of eastern Quebec. No reference corridor combines ALTO’s pattern of maximum subgrade, ecological, and greenfield-integration scores.

    A Fair Reading

    Concentrated, not uniform — the exposure-adjusted view

    The Peak Severity composite of 82 treats a dimension as fully present wherever its worst severity appears. But ALTO’s complexity is not uniformly distributed: Leda clay occupies a majority of the corridor, while the hard-rock Frontenac Arch crossing is concentrated in roughly 40 km and urban engineering is confined to four metropolitan termini. The Exposure-Adjusted composite, which scales each dimension by the share of corridor length at which its peak severity is present, comes to 73 out of 100 — in the upper High band, nine points below the Peak Severity figure.

    The gap between the two indices is itself the finding: it quantifies how much of ALTO’s complexity is concentrated rather than spread along the whole route. The dimensions with the largest downward adjustment — bedrock, urban engineering, and ecological — are real, significant engineering burdens, but ones concentrated in specific segments. Reported honestly, both numbers belong in any cost forecast: Peak Severity drives the design-capability case for independent peer review; Exposure-Adjusted informs the corridor-scale cost envelope.

    The 82 is also presented as a conservative baseline, not a worst case. The scoring follows a stated conservatism principle — where evidence straddles two levels, the lower score is taken unless the higher is documentably met. Six dimensions are identified where fuller review could justify an upgrade; if all six conditions were met, the composite would rise to 92. The defensible range is therefore 82–92 — all of it within the Extreme band.

    The Alternative

    Where the High Performance Rail alternative changes the score

    The complexity score is not a fixed property of the route — it is a property of this design choice for the route. The High Performance Rail (HPR) alternative is structured to avoid the most consequential maximum-score dimensions by design, and a parallel scoring of HPR against the same rubric is recommended as a companion exercise. Preliminary assessment places it in the Moderate-to-High transition, a range for which the database provides abundant delivery precedent.

    Land acquisition (D9): 5/5 → toward 2/5

    Greenfield land acquisition — ALTO’s maximum-score dimension — is substantially replaced by upgraded use of shared existing corridors, removing the tens-of-thousands-of-property-interests problem that places ALTO at the Extreme archetype.

    Subgrade & ecology (D1, D7): materially mitigated

    Following existing corridors means the sensitive-clay and critical-habitat crossings have, in large part, already been engineered or disclosed — rather than encountered fresh along a new greenfield alignment.

    Urban engineering (D10): unchanged

    HPR uses the same existing urban rail corridors into the same metropolitan termini, so urban engineering content stays at or below its current score — a useful reminder that the alternative is not a free lunch on every dimension.

    The Honest Answer

    What does an Extreme score oblige?

    The rubric is explicit on this point, and it is not a matter of opinion: an Extreme-band project requires independent peer review and reference-class forecasting as mandatory, not discretionary. These are the mechanisms by which a frontier-engineering project is costed responsibly. They are not discharged by a public consultation, nor by a standard environmental assessment.

    The primary governance finding of the scoring exercise is the absence of those mechanisms from the current procurement trajectory. That is not, in itself, a verdict that the corridor should not be built. It is a statement that the cost number attached to it cannot yet be relied upon — because the discipline that would make an Extreme-band forecast trustworthy has not been applied to it.

    This is the same shape of argument the Initiative’s financial work makes elsewhere: the question is rarely whether a number is high or low, but whether the method behind it can be audited. A reader who knows the corridor scores in the Extreme band can ask, of any cost forecast presented for it, which comparators were used — and whether they were dimensionally matched, or merely favourable.

    For the Next Cost Estimate

    Three questions to ask of any HSR cost forecast

    Each follows directly from the rubric. None presupposes opposition to any project. Each is the kind of question the method requires to be answered before a cost figure can be trusted.

    1. Which comparators were used — and what do they score?

    A forecast anchored on lines scoring in the 40s or 50s is borrowing the cost of a fundamentally less demanding corridor. Ask for the complexity score of each comparator, and whether any of them is dimensionally matched to the proposed corridor rather than simply convenient.

    2. Has independent peer review and reference-class forecasting been done?

    For an Extreme-band corridor these are mandatory, not optional. If they have not been performed, the cost estimate is provisional by definition, however precise the headline figure looks.

    3. Have the interaction effects been costed, not just the dimensions?

    The composite treats dimensions as independent; real corridors do not behave that way. For ALTO specifically, the subgrade–geohazard coupling — remediation works in sensitive clay potentially triggering slope failures — belongs on the risk register as an explicit line item.

    None of these questions presupposes a view about whether the corridor should be built. Each is the kind of question a reasonable reader would ask before forming one — and each is a question the published cost materials have so far not been pressed to answer in the terms the method requires.

    Reading Lovegrove

    What the UK Cabinet Office’s review of the HS2 Civil Service failures tells us about ALTO.

    ALTO HSR Citizen Research Initiative · Governance Brief · Published May 2026
    ⚠ New UK Cabinet Office Review Published

    In May 2026 the UK Cabinet Office published a review by Sir Stephen Lovegrove — former National Security Adviser and former Permanent Secretary of the Ministry of Defence — into how the British Civil Service failed to identify and act on the deterioration of HS2 before its costs reached £82.2 billion for the London–Birmingham section alone. The review is short, unusually candid, and addresses the institutional architecture Canada is now using to deliver ALTO. gov.uk

    The Lovegrove Review is not about why HS2 went wrong as an engineering project. Its purpose is to explain how a senior G7 civil service, with all the oversight tools a Westminster-system government has, failed to see the disaster coming. That makes it directly relevant to the question Canadians need to ask about ALTO.

    Critical Finding

    The Lovegrove Review documents a four-fold real-terms increase in HS2 Phase 1 costs between 2012 and 2026 — from £20.5 billion to £82.2 billion in constant 2019 prices — on a 225-kilometre stretch of railway. A directly parallel Canadian cost-escalation trajectory has already occurred on the corridor ALTO now proposes to serve: from under C$5 billion for the abandoned High Frequency Rail option in 2016 to C$80–120 billion for ALTO as confirmed in February 2025, a sixteen-to-twenty-four-fold increase within a decade.

    Three Lovegrove findings translate directly to ALTO. First, the corporate form of an arm’s-length delivery body funded entirely from the public purse — HS2 Ltd in the UK, ALTO HSR Inc. in Canada — is, in Lovegrove’s words, “fundamentally ill-suited to this type of arrangement” because the commercial disciplines the corporate form is supposed to deliver do not flow from grant-in-aid funding alone. Second, HS2 Ltd’s board and executive developed a “fortress mentality,” becoming cheerleaders for high-speed rail rather than rigorous delivery managers — a pattern the CRI has been documenting in ALTO’s recent public outputs. Third, and most directly applicable: external reviews must not substitute for official advice on alternative ways of delivering a project before a Final Investment Decision.

    The Lovegrove Review also contains an unusually explicit vindication of dissenting analysis. Lord Berkeley’s January 2020 dissent from the Oakervee panel was dismissed at the time as methodologically unsound. Six years later, the Cabinet Office writes that the thrust of his judgements has proved correct and his estimates closer to today’s outturn than those on which ministers gave the go-ahead. This is the most authoritative G7 government statement to date on the credibility of structured citizen reference-class analysis in high-speed rail governance.

    A Published Reference Class

    The cost trajectory the UK Cabinet Office published this month

    The single most useful artefact in the Lovegrove Review is its published trajectory of HS2 Phase 1 cost estimates over time, all expressed in a 2019 price base for comparability. Phase 1 is the London to West Midlands section of approximately 225 km — the only section now being constructed, after the cancellation of Phase 2 north of Birmingham.

    YearPhase 1 cost estimate (£bn, 2019 prices)
    201220.5
    201326.8
    202044.6
    202354
    202466
    202682.2

    In 2019 prices, the 2026 estimate is more than four times the 2012 estimate for the same 225 km of railway. The increase from 2024 to 2026 alone — two years — is larger than the entire original 2012 budget. This is not a critic’s estimate. It is not an academic reconstruction. It is the British government, today, publishing the official trajectory of its own project’s cost.

    For ALTO, the importance of this trajectory is twofold. The comparator is not ancient: HS2 Phase 1 was at roughly the same stage of pre-construction maturity in 2012–2015 that ALTO is at now. And the trajectory is now an official UK government data point — not contested or speculative — which removes one of the standard rhetorical defences used in ALTO’s framing.

    The Canadian Parallel

    The same trajectory has already occurred on the Toronto–Quebec City corridor

    In 2016 the federal government funded a serious study of High Frequency Rail (HFR) for the Toronto–Quebec City corridor: 170–177 km/h conventional rail on largely dedicated tracks, costed at under C$5 billion in 2016 dollars, or under C$10 billion adjusted for construction inflation to 2024. A December 2021 Joint Project Office Business Case prepared by VIA Rail Canada and the Canada Infrastructure Bank confirmed the preferred option. tc.canada.ca

    In March 2022 the federal government issued a Request for Expressions of Interest that pivoted the procurement to a Design-Build-Finance-Operate-Maintain (DBFOM) structure and explicitly invited proposals for speeds above 200 km/h. In February 2025, without publishing a side-by-side comparison of the HFR and high-speed options, the government confirmed the project would become ALTO at 300 km/h+, costed at C$80–120 billion. Passengers will not board until the 2040s.

    The escalation from HFR’s published baseline to ALTO’s announced range is of the same order of magnitude as, and on a comparable timescale to, the four-fold real-terms increase Lovegrove documents for HS2 Phase 1. The HS2 cost-trajectory table above is not a foreign curiosity. It is the comparator for a transformation that has already occurred on the project Canada is now committing to deliver.

    The “Original Sins”

    Lovegrove’s consensus diagnosis — and its ALTO analogues

    Lovegrove summarises the consensus diagnosis of why HS2 cost forecasts proved so wrong. The list is short and direct: original gold-plating of the high-speed concept; a decision to begin construction at the hardest points of the route; changing objectives and political priorities; award of the Main Works Civils Contracts at insufficient design maturity and on terms which did not manage risk; and costs and risks badly underestimated.

    The pursuit of 300 km/h electrified high-speed running across a route with the geological and ecological profile of the proposed southern corridor is itself a gold-plating decision. Reference-class analysis shows that the marginal capital cost of moving from a conventional or near-conventional dedicated passenger railway to a fully grade-separated electrified high-speed alignment is the dominant driver of total programme cost — and is the primary mechanical reason the HFR-to-ALTO transformation generated the cost escalation set out above. An alternative configuration — a lower design speed in the order of 200 km/h, on a route making use of the 401 corridor rather than a new southern alignment across Eastern Ontario — would shift the project into a different cost class and a different environmental and community-impact profile. Whether such a configuration is preferable, on a full set of criteria, is precisely the comparative question the Lovegrove framework says government should answer before a Final Investment Decision.

    The HS2 phasing parallel is not exact: ALTO plans to begin with the Ottawa-to-Montréal segment, which involves real engineering complexity including Leda clay deposits and the Ottawa River crossing, but is not the hardest section of the proposed corridor. The more challenging geological and ecological terrain remains to be worked through downstream of any Notice-to-Proceed-equivalent decision. The category of risk Lovegrove identifies nonetheless applies: committing to a DBFOM contractual architecture spanning the full corridor before the hardest sections have been designed in detail locks in contractual obligations under the same design-immaturity conditions HS2 entered when it awarded its Main Works Civils Contracts. The HS2 mistake was not solely the geographical choice to start in the Chilterns; it was the contractual choice to commit before maturity, and that part of the parallel remains direct.

    Sir Jon Thompson, the Executive Chair of HS2 Ltd, set out the resulting contractual problem directly in evidence to the House of Commons Transport Committee on 10 January 2024. parliament.uk He told the Committee that the Government and the company had decided to let cost-plus contracts under which 99% of the financial risk sat with the Government and only 1% with the contractor, describing the arrangement as extraordinary. Under a fixed-percentage fee, he noted, a contractor who runs over budget receives the same percentage of a much larger number, which effectively incentivises overspending rather than restraining it.

    The risk allocation under the ALTO co-development contract with the Cadence consortium has not been publicly disclosed. Whether it replicates, mitigates, or improves on the HS2 risk allocation cannot be assessed from public information. Under Lovegrove’s framework, that absence of disclosure is itself the relevant problem: the contractual terms that drive cost outcomes over the lifetime of a project are exactly the terms that the sponsor department, Parliament, and the Auditor General require visibility into before, not after, commitment.

    The Crown Corporation Problem

    Lovegrove’s structural critique of the delivery vehicle

    Lovegrove’s most pointed structural critique is of HS2 Ltd’s status as a Company Limited by Guarantee with government as sole guarantor. The Review concludes that this construct was institutionally incoherent. The arguments traditionally offered for it — independence from government, ability to hire at market rates, commercial discipline, decision-making at commercial speed — are real benefits, but they only work when the entity has genuine third-party shareholders with capital at risk.

    “Company structures are arguably fundamentally ill-suited to this type of arrangement.”

    — Lovegrove Review, May 2026

    HS2 Ltd received 100% of its funding from government grant-in-aid. There were no third-party shareholders, no commercial counterparties with capital at risk, no governance mechanisms forcing cost-benefit discipline from below. The advantages of the company form were thus retained only in name. What HS2 Ltd actually got was the freedom to hire at private-sector rates and to operate at arm’s length from ministers, without the corresponding discipline of having investors who would have insisted on cost control.

    ALTO HSR Inc. is in a structurally comparable position to HS2 Ltd at the corporate level. It is a federal Crown corporation, 100% publicly funded, with no third-party shareholders in the corporation itself. The contractual relationship with the Cadence consortium under the DBFOM arrangement is not publicly disclosed in sufficient detail to assess how risk, financing, and return are allocated between the parties or over what time horizon. What can be observed from the public record is the corporate-form question: a Crown corporation receiving 100% of its funding from the federal purse, used to obtain independence from political cycles and freedom to hire specialist talent, is in the same structural category as HS2 Ltd — the category Lovegrove diagnoses as institutionally incoherent because the disciplines that normally accompany the corporate form do not flow from grant-in-aid funding alone.

    The “Fortress Mentality”

    A cultural pathology, and a downstream information failure

    Beyond structure, Lovegrove identifies a cultural pathology that should be familiar to anyone tracking ALTO’s public communications. The Review records that HS2 Ltd’s board, and particularly its executive management and chair, developed what interviewees described as a fortress mentality — becoming cheerleaders not only for HS2 but for the cause of high-speed rail in the UK more generally, framing the project as ushering in a new era. The Review is unambiguous that this conception of the company’s role was misguided. Transport policy is for ministers; the company’s job is delivery within scope and budget.

    “The Board, and especially the executive management and Chair, had adopted a ‘fortress mentality’ and had become ‘cheerleaders’, not merely for HS2 but for the cause of high-speed rail in the UK more generally.”

    — Lovegrove Review, May 2026

    This cultural finding matters because it generated a downstream information failure. Lovegrove quotes board members and reviewers describing the management information packs given to the HS2 Ltd board as forming a veil behind which less good news became difficult to assess or even identify, with the same problem persisting unaddressed years later — packs remaining unwieldy, format-inconsistent, and lacking prioritisation. Because the same data flowed through to government, the sponsor department was working from the same compromised information.

    The CRI’s post-consultation work has documented precisely this pattern in ALTO’s public outputs. The disclosures in Q-923 on cost, ridership, and the self-sustaining claim use confidence framings that do not survive parametric stress-testing against McGill TRAM and Munk School sources. The marketing pivot identified through the Cossette ATI disclosures, and the unanswered status of TRAN Report 18 — published by the House of Commons Standing Committee on Transport, Infrastructure and Communities and left without a government response when Parliament was prorogued — are the documentary symptoms of an executive culture that has begun to treat advocacy as primary and delivery information as secondary. Lovegrove’s framework gives that observation a name and an authoritative diagnostic basis.

    The candour of Sir Jon Thompson’s evidence to the Transport Committee on 10 January 2024 is worth pausing on, because it confirms the Lovegrove diagnosis from inside the institution. Thompson — himself a former Permanent Secretary at HM Revenue and Customs and at the Ministry of Defence, and a double-qualified accountant — told the Committee that when he joined the HS2 board in 2021 he was struck by the lack of data and scrutiny of programme finances; that the management information presented to the board was not robust enough to assess whether main civils contractors were meeting productivity targets; and that significant improvement only arrived in October 2023, two and a half years later. He described it as a shocking thing to say, but acknowledged that the quality of board-level management information had not been good enough. That is the senior executive of a major UK arm’s-length delivery body, on the parliamentary record, confirming the exact information failure the Lovegrove Review now documents externally.

    The Notice-to-Proceed Moment

    When external reviews substitute for official advice

    The Lovegrove Review devotes substantial attention to the Notice to Proceed decision in early 2020, when government formally committed to construction of HS2 Phase 1. The sequence is instructive. The Oakervee Review, an independent panel chaired by a former HS2 Ltd chair, recommended proceeding with the full route. Its report was published shortly after a Prime Minister–Chancellor–Secretary of State trilateral meeting had already reached the same conclusion. The formal Notice to Proceed was confirmed in March 2020.

    Lovegrove’s criticism is not that the Oakervee Review was conducted in bad faith. It is that the official advice provided to ministers alongside the Oakervee report did not address alternative ways of delivering the project — as distinct from alternative projects — including options which would have led to a delay in construction while alternative designs, options, or contractual arrangements were sought. The external review effectively substituted for official advice on strategic choice.

    “Reviews by external actors (including this one) have their place in informing policy formulation, but they should not substitute for official advice.”

    — Lovegrove Review, Recommendation 14

    This is the recommendation with the most direct bearing on where ALTO now sits. The work being produced by Cadence under its co-development contract, the public outputs of ALTO HSR Inc., and the materials prepared for the parliamentary process are all in danger of functioning as external review substituting for official advice on alternatives. The category of alternative Lovegrove insists should not be foreclosed before a Final Investment Decision — different speed classes, different route alignments, different contractual structures, different phasing — is exactly the category that has not been comparatively analysed for ALTO. A lower design speed in the order of 200 km/h, and a route making use of the 401 corridor rather than a new southern alignment, are concrete examples of the alternatives that would normally be costed and compared at this stage. They have not been.

    The CRI’s March 2026 brief From HFR to ALTO already constitutes the kind of structured comparison Lovegrove says government itself should produce. It identifies eight pivotal changes that occurred between the December 2021 HFR Business Case and the February 2025 confirmation of ALTO as a high-speed system, and documents the absence of a published side-by-side cost-benefit comparison between the two options. The point under Lovegrove’s framework is not that citizen research is a substitute for official advice. It is that when an arm’s-length delivery body and the sponsor department do not produce that comparison themselves, and the government nonetheless proceeds, the conditions Lovegrove identifies as the proximate cause of the HS2 failure are present.

    Vindication of the Dissenting Voice

    The lone dissenter the Cabinet Office now says was right

    One paragraph of the Lovegrove Review deserves to be read by every parliamentarian considering ALTO. When the British government was deciding whether to proceed with HS2 in 2020, it commissioned an independent panel chaired by a former HS2 chair, Douglas Oakervee. The panel recommended proceeding with the full project. One member dissented — Lord Berkeley, a peer and former rail executive. His dissenting report cast doubt on the costings, the schedule, and the capability of HS2 Ltd to manage the project. He was dismissed at the time as methodologically unsound. His report was excluded from the panel’s formal conclusions.

    “There is no escaping the fact that the thrust of his judgements, in particular about the capability of the Company to manage the project, have proved to be correct, and his estimates much closer to today’s outturn than those upon which ministers ultimately gave the go-ahead.”

    — Lovegrove Review, May 2026

    That is the UK Cabinet Office, six years later, on the public record, telling Parliament that the man it ignored was right. His estimates were closer to reality than the ones ministers used to make the final decision. The institutional process designed to test his concerns failed.

    This matters for Canada because it is the most authoritative statement any G7 government has ever made about the value of structured outside-the-tent analysis on a major infrastructure project. It does not validate every dissenting analysis automatically — Lovegrove notes that some of Berkeley’s specific methodological steps were questionable and that some of the cost increases arose from factors Berkeley did not identify — but it establishes that the dismissal of dissenting reference-class work as inherently less credible than insider forecasts has now been formally repudiated by one G7 government.

    Corporate Overlap

    Two Cadence members were inside HS2

    Two of the six members of the Cadence consortium selected by Canada to design, build, finance, operate and maintain ALTO were directly embedded in HS2 work during the period that the Lovegrove Review now criticises.

    AtkinsRéalis

    The Canadian engineering firm that rebranded from SNC-Lavalin in 2023, and the lead Canadian engineering member of Cadence, was part of the CH2M / Atkins / SENER Engineering Delivery Partner joint venture for HS2 Phase One. That ten-year contract was awarded in 2016 and was valued between £250 million and £350 million. The Engineering Delivery Partner role placed Atkins inside HS2 Ltd, fully integrated, with explicit responsibility for supporting the preparation and procurement of the Main Works Civils Contracts — the contracts that the Lovegrove Review identifies as awarded at insufficient design maturity and on terms which did not manage risk. Atkins’s UK arm was acquired by SNC-Lavalin in 2017, mid-way through the contract, and is now part of AtkinsRéalis.

    SYSTRA

    The French rail engineering firm and a Cadence member was part of the Mott MacDonald / SYSTRA design joint venture working alongside the Balfour Beatty VINCI construction joint venture on HS2 Lots N1 and N2 of the Main Works Civils Contracts — the 90 km West Midlands stretch including the Long Itchington Wood Green tunnel and the Birmingham approaches. SYSTRA was also a partner in the BBV-SYSTRA (BBVS) joint venture for the Old Oak Common station in London. SYSTRA’s role on HS2 was thus across both design and construction-management functions on the very contracts whose financial architecture HS2’s own chair has publicly criticised before the UK Public Accounts Committee.

    These observations are factual, not attributive. The Lovegrove Review is explicit that the institutional failure on HS2 lay primarily with HS2 Ltd’s governance and culture and secondarily with the Civil Service, not with the contractor firms per se. Many of the firms involved are world-leading rail engineers, and their inclusion in Cadence reflects that. The point is that two firms whose immediately prior major HSR engagement is now the subject of a Cabinet Office post-mortem on cost control are now central to ALTO’s design, build, and ongoing operation under a DBFOM structure. For parliamentarians and analysts considering whether the lessons of HS2 are being absorbed into ALTO’s procurement and oversight, this is a fact that warrants disclosure in any briefing material on the project.

    Implications for ALTO

    What this changes

    Canada has the same parliamentary system as the United Kingdom. The same Treasury Board controls. The same Crown corporation tools. The same Public Accounts Committee. The same Auditor General. The institutional architecture that failed at HS2 — and that Lovegrove has now diagnosed in unusual detail — is the architecture being used to deliver ALTO.

    The HS2 cost trajectory is now an official G7 reference class

    The Cabinet Office published trajectory — £20.5bn (2012) to £82.2bn (2026) in constant 2019 prices — is now an official G7 data point. It belongs in every cost-related submission, briefing letter, and parliamentary communication on ALTO between now and a Final Investment Decision.

    The Crown corporation critique applies directly

    The structural critique of the Company Limited by Guarantee model translates directly to ALTO HSR Inc. The case for Crown-corporation delivery has been overstated; the commercial discipline its proponents claim does not flow from the structure adopted when 100% of funding comes from the public purse.

    Recommendation 14 creates a concrete obligation

    Government, not contractors, must produce the comparative analysis of alternative ways of delivering the project — including alternative speed classes and route corridors — before any Notice-to-Proceed-equivalent decision. Doing it after commitment is, in Lovegrove’s framework, too late.

    Berkeley’s vindication establishes a precedent

    The Cabinet Office’s 2026 vindication of Lord Berkeley’s 2020 dissenting report establishes a public-record precedent for the credibility of structured citizen reference-class analysis in HSR governance. That precedent is now available to be cited.

    The AtkinsRéalis / SYSTRA overlap warrants disclosure

    The involvement of two Cadence members in the HS2 work the Lovegrove Review now criticises is a material fact for parliamentarians considering whether ALTO’s procurement reflects institutional learning from HS2, or the application of the same contractual architecture in a different jurisdiction.

    The Lovegrove and Stewart Reviews together represent the most current, most senior statement by a G7 government on what arm’s-length high-speed rail delivery requires of a Westminster-system sponsor department. The lessons set out in the Lovegrove Review are not lessons Canada needs to learn the hard way. They are available now.
