ALTO is starting where rail already works
The Ottawa–Montréal segment is ALTO’s first construction phase — and the corridor’s weakest case for high-speed rail.
ALTO has confirmed that the Ottawa–Montréal segment will be the first phase of construction, with work to begin in 2029–30. ALTO CEO Martin Imbleau publicly describes the segment as “shorter and technically simpler”; Transport Minister Steven MacKinnon called it “relatively short, flat and straight”; ALTO’s own consultation materials describe it as a “learning segment” — a test case to refine before scaling to the rest of the corridor.

The case ALTO is starting with is the strongest case for HSR that the project can publicly make. If the case fails on this segment, it fails on the corridor.
The Ottawa–Montréal segment is ALTO’s strongest case for high-speed rail. It is also the corridor’s weakest case for it. VIA Rail owns the bulk of this 185-km line — the 110-km Alexandria Subdivision from Ottawa east to Coteau Junction, Québec — and on this VIA-owned segment, on-time performance runs at approximately 90%, well above any other corridor route. The freight-conflict problem that ALTO exists to solve is confined to the ~65-km CN-owned approach into Montréal from Coteau Junction.
ALTO’s CEO has publicly refused to estimate the segment cost. The project will require crossing approximately 1,700 properties, including roughly 500 farms, in a 60-metre right-of-way through Eastern Ontario and western Québec farmland, with construction taking 8–10 years — to save approximately 25–30 minutes of travel time. The alternative — upgrading the existing line to High Performance Rail — would deliver nearly the same time savings at a fraction of the cost, decades sooner, without greenfield expropriation. The federal government has never produced a public comparison.
ALTO picked Ottawa–Montréal because it’s the easiest. They said so.
In December 2025, the federal government announced that the Ottawa–Montréal segment would be the first construction phase of the ALTO project. The rationale offered, publicly and consistently, has been that this segment is the most straightforward to deliver. ALTO CEO Martin Imbleau has described it as “shorter and technically simpler” than the rest of the corridor. Transport Minister Steven MacKinnon called it “relatively short, flat and straight.” ALTO’s own consultation materials describe Ottawa–Montréal as a “learning segment” that will be used to refine delivery methods before scaling to the Toronto and Québec City segments.

This framing is not incidental. The Toronto and Québec segments are technically harder, politically harder, and considerably more expensive. The Toronto segment must enter a constrained urban transportation system; the Mount Royal tunnel approach to Montréal on the Québec end carries McGill engineering estimates exceeding $1 billion per kilometre. ALTO is leading with Ottawa–Montréal because it is the demonstration most likely to succeed, and because demonstrating success here is the political precondition for proceeding with the rest. The whole project’s institutional credibility now rests on a segment ALTO itself has framed as its strongest case for HSR.
The test-case logic, stated by ALTO itself
Imbleau told the US High Speed Rail Conference that the Ottawa–Montréal segment is “a learning segment to refine delivery methods before scaling to the full network.” By starting here, the project “can validate assumptions and manage scope responsibly before expanding east and west.” The strongest case ALTO can make for high-speed rail is the case on this segment. If validation fails here, the rest of the corridor cannot inherit a successful demonstration.
The Ottawa–Montréal train is the corridor’s most reliable service
VIA Rail Ottawa–Montréal currently runs 34 or more scheduled departures per week over 185 km, with an average travel time of 2 hours 4 minutes. The route’s defining characteristic is not its speed; it is its reliability. Unlike most of the Québec City–Windsor corridor, where VIA passenger trains share track with CN-owned freight operations, VIA Rail owns the bulk of this line — specifically the 110-km Alexandria Subdivision running from Ottawa east to Coteau Junction in Québec. CPTDB Wiki VIA Rail
VIA Rail confirmed to CBC News that on-time performance on this VIA-owned segment runs at approximately 90% — significantly better than any other corridor route. By comparison, VIA’s national on-time performance has hovered between 65% and 75% over recent years, with the gap explained almost entirely by passenger trains being held in sidings while CN freight passes through. Where VIA controls the dispatch, the trains run on schedule. CBC News
The reliability problem is a freight-conflict problem
ALTO repeatedly cites VIA’s poor on-time performance as the justification for HSR investment. That problem is real on most of the corridor: across VIA’s national network, 97% of the track it operates on is owned by other companies, mostly CN. But the poor reliability is concentrated on the freight-shared segments. On the segment ALTO is starting with, the problem is already substantially solved — not by ALTO, but by VIA’s existing ownership of the line.
The freight conflict ALTO exists to solve barely exists here
ALTO’s entire rationale — what justifies the $60–90 billion estimated price tag for a dedicated passenger-only high-speed line — is that VIA passenger trains share CN-owned freight track across most of the Québec City–Windsor corridor and get pushed aside whenever freight passes. Building a new dedicated passenger-only line is presented as the solution. ALTO consultation
On Ottawa–Montréal, the problem is already mostly solved. The 110-km Alexandria Subdivision from Ottawa to Coteau Junction is owned and dispatched by VIA Rail. Passenger trains on this segment have priority because VIA controls the line. The 90% on-time performance reflects exactly that. The freight conflict that does exist on this route is confined to a relatively short stretch — the approximately 65-km CN-owned approach into Montréal from Coteau Junction, where VIA trains pick up CN’s Kingston Subdivision into Central Station. CPTDB Wiki
The proportionality problem this creates for ALTO’s case is significant. If the freight-conflict problem on Ottawa–Montréal is confined to roughly 65 km of CN-owned approach to Montréal, the corresponding intervention is a 65-km fix, not a 185-km greenfield replacement. The targeted alternatives — track-sharing reform, capacity upgrades, dedicated passenger right-of-way on the CN section, or a publicly negotiated priority agreement with CN — have not been publicly evaluated against the cost and disruption of the ALTO HSR plan on this segment.
Starting where the problem isn’t
ALTO is starting construction by replacing the segment of the corridor where reliability is already strongest, and where the freight-conflict problem ALTO claims to solve is structurally smallest. That is not a demonstration of HSR’s necessity. It is a demonstration of where institutional and engineering risk is lowest — precisely the segment where the case for HSR specifically is weakest on the merits.
ALTO refuses to put a number on this segment
Asked directly at the December 2025 announcement to estimate the cost of building HSR on the Ottawa–Montréal segment, ALTO CEO Martin Imbleau refused. “It would be difficult to have an estimate,” he told reporters. He added that it would be “kind of absurd to have an independent budget” for a portion of the corridor. Eight months later, no segment-specific cost figure has been published. The project’s overall $60–90 billion estimate is, in Imbleau’s own May 2026 characterisation, a working assumption rather than a cost estimate; reliable estimates are expected only in 2027 or 2028, after engineering follows alignment selection. CBC News
What ALTO has confirmed about the segment is what it would take to build it. The line will cross approximately 1,700 properties, including roughly 500 farms (about 40% of the total acquisitions), in a 60-metre fenced right-of-way through Eastern Ontario and western Québec farmland. Construction will take 8–10 years, with no passenger service on the segment until the late 2030s. The travel-time saving, as currently projected: approximately 25–30 minutes, taking the Ottawa–Montréal journey from 2h 4min to roughly 1h 35min. CBC News
The price ALTO has named, even without a cost figure
Twenty-five minutes saved on a route that already arrives on time approximately 90% of the time. For an undisclosed cost. Crossing 500 farms, in the segment ALTO itself has chosen as its strongest case for high-speed rail. The federal commitment is not to a price; it is to a process — corridor narrowing in autumn 2026, formal letters to property owners before that corridor is publicly disclosed, acquisition beginning in late 2026 or early 2027, ahead of any segment-specific cost estimate the public can scrutinise.
High Performance Rail on the existing line
There is an alternative that addresses the corridor’s actual problem — reliability where freight conflict exists — without replacing what already works. High Performance Rail (HPR) on the existing Ottawa–Montréal line means upgrading the VIA-owned track to dedicated passenger speeds of approximately 200 km/h, with targeted intervention on the CN-owned Montréal approach to address the reliability bottleneck where it actually lives. Operational time on the upgraded line would be approximately 1 hour 40 minutes — within minutes of ALTO’s projected 1h 35min on a brand-new HSR alignment, and roughly 25 minutes faster than today.
| ALTO HSR (planned) | HPR on existing line | |
|---|---|---|
| Travel time Ottawa–Montréal | ~1h 35min projected | ~1h 40min projected |
| Travel time saved vs. current VIA (2h 4min) | ~25–30 minutes | ~20–25 minutes |
| Operational by | Late 2030s (construction 2029–30, then 8–10 years) | 3–5 years from project start |
| Capital cost | Undisclosed; project total $60–90B | A fraction of ALTO’s segment cost |
| Properties affected | ~1,700, including ~500 farms | Minimal — existing right-of-way |
| Right-of-way | New 60-metre fenced corridor | Existing VIA-owned alignment |
| Downtown stations | Mount Royal tunnel required for Central; Ottawa station status “not ideal” | Ottawa rail station and Montréal Gare Centrale preserved |
| Rolling stock | New procurement | VIA’s already-purchased Siemens Venture fleet |
| National network impact | Cross-subsidy from corridor revenue diverted to private operator | VIA’s national network preserved |
The federal government has never produced a public comparison of HSR against HPR on this segment. The procurement process has moved from concept directly to dedicated-corridor HSR design without an intermediate evaluation of whether the existing line, upgraded, would deliver most of the benefit at a small fraction of the cost. This is not a question of opposing modernisation. It is a question of what modernisation is being procured, against what alternatives, and at whose recommendation.
The integrated-network case
HPR on Ottawa–Montréal would be one piece of an integrated rail network upgrade: dedicated passenger track on the existing Toronto–Montréal CN Kingston Subdivision, upgrades to existing alignments where they already work, targeted new construction where genuinely needed. The result is faster trains on every existing corridor route, not a single greenfield HSR line bypassing the network that exists. The federal government has commissioned twenty-eight studies into the 300 km/h vision. None into this.
Three questions for the Minister of Transport
Construction on the Ottawa–Montréal segment is currently scheduled to begin in 2029–30, with corridor narrowing in autumn 2026 and acquisitions beginning shortly after. The window to compel the government to produce, and publish, an independent comparison of HSR against the HPR alternative on this segment is narrow. Three questions, the kind that must be answered or visibly declined, are sufficient to make the case for that comparison politically unavoidable.
- Publish a cost estimate for the Ottawa–Montréal segment specifically, before construction begins in 2029–30. ALTO’s continued refusal to do so on a publicly funded project of this scale is not justifiable.
- Publish a public comparative analysis of HSR versus HPR on the existing Ottawa–Montréal line — time, cost, disruption, and timeline side by side, with the methodology disclosed.
- Refer ALTO to the Parliamentary Budget Officer for independent review of the fiscal, ridership, and station-location assumptions underpinning the project before construction commitments are made.
Also write to your Member of Parliament — Ottawa-area, Eastern Ontario, and western Québec MPs in particular have constituencies that will bear the operational consequences of the choices made now. The decision to refer the project to the PBO for independent review can be initiated through any MP.
