Alto’s demand case, in its own words

In an April 17, 2026 opinion piece published in the Toronto Star and La Presse and reproduced on altotrain.ca, Alto’s chief executive set out the demand case for the Toronto–Québec City high-speed line. Its central figures are a headline market of ninety-five million intercity trips a year across the corridor, rising to one hundred and forty million by 2049; a population of eighteen million reaching twenty-two million within fifteen years; and a target of twenty-four million annual passengers by 2055, presented as consistent with international outcomes. The piece is framed to reassure — its very title insists that high-speed rail is no leap of faith.

This brief tests the claim on its own terms. It does not dispute that the corridor is large, that it is growing, or that its intercity system is under strain — all three are true. It disputes the inference the commentary draws from them: that a twenty-four-million forecast is therefore measured, modest, and safe.

Read against three independent bodies of evidence — the corridor’s roadside traffic counts, the population path Statistics Canada now projects, and the international record of what comparable high-speed lines actually carry — the demand case rests on optimistic framing rather than measurement. Where the commentary offers large round numbers and a single favourable analogue, the evidence points to central ridership near a third of the headline, and to a growth story built on a population Canada has already walked back.

Six findings

The findings rest on four independent methods, each built to be reproducible from public data: a reference class of comparable corridors, a modal-shift ridership model, a market-by-market demand build-up, and a re-basing on Statistics Canada’s current population. A fifth lens — the standard appraisal treatment of optimism bias — governs how all four are read.

What comparable corridors actually carry

Rather than model the corridor from assumptions, the reference-class method asks what corridors with similar car dependence, density, and trip lengths actually achieve once fast rail opens. Each candidate corridor is scored on a Car Dependency Index (CDI) — a composite of car mode share, population density, and transit provision at the endpoints. The Toronto–Québec City corridor’s high car dependence places it with reference cases that, rescaled to this line, carry the equivalent of roughly 4 to 5 million corridor trips a year at maturity. This is the risk-adjusted floor: what the evidence says the corridor is most likely to do before any speed, fare, or density assumption is layered on.

Demand, counted not modelled

A fast service on this corridor draws from three distinct current populations: the car market, the air market on the competitive city pairs, and the existing rail riders. Each is measurable from public data. Because they are distinct populations, they add without double-counting.

The car market is read at the Highway 401 screenline where it crosses into Québec, after Ottawa-bound traffic has left via Highway 416 and Cornwall-local traffic has loaded, stripped of the 30 to 35 per cent commercial-truck share and short regional trips: roughly 8.8 to 11.0 million end-to-end car person-trips a year across the triangle at an occupancy of 2.0. Applying the road-market capture rates converts these into the rail ridership the car market alone would yield.

The car market is only one of three. A fast corridor service also draws from the air travellers on the same city pairs, and it retains the passengers already riding the train. The corridor air market on the competitive pairs — Toronto–Montréal, Toronto–Ottawa, and the smaller Ottawa–Montréal — is on the order of 2.5 to 3.0 million point-to-point passengers a year, of which a fast train on these distances captures about two-thirds.

Existing conventional rail is now reported directly in VIA’s 2025 annual results: 3.34 million passengers a year on the Corridor East service group (Québec City–Montréal–Ottawa–Toronto), within a Québec City–Windsor corridor total of 4.18 million. Essentially all of the triangle share is retained by a faster, more reliable service. VIA’s audited subsidy figures also fix the shape of the trip-length distribution: 48.51 dollars per passenger over 0.22 dollars per passenger-mile is an average trip of about 355 kilometres — roughly a third of the end-to-end corridor distance. Even the passengers already choosing rail are, on average, taking journeys well short of the full corridor.

The 6.3-million deficit

Every ridership figure scales with the population beneath it, so the choice of population path is decisive. The brief uses Statistics Canada’s January 2026 projection (catalogue 17-20-0003), which incorporates the 2024–25 federal Immigration Levels Plan.

Against the pre-2024 growth path that older corridor forecasts — and the commentary’s twenty-two-million figure — assume, this is materially lower: the corridor reaches about 19.8 million by 2055 on the current path, versus 26.1 million on the counterfactual, a deficit of 6.3 million. Because ridership scales with population, a forecast on the old path is inflated by roughly the same proportion the population has been cut — before any question of mode share or capture even arises.

Where Alto’s target sits against every independent forecast

The three methods converge. The demand-side build-up sums to about 8 to 9 million a year; the bottom-up modal-shift model lands in the same place; the reference class puts a floor near 4 to 5 million. Set beside the full band of independent corridor estimates, Alto’s 24-million target stands alone above every one.

Where the 95-million figure appears — and where it doesn’t

A demand denominator on which a $60–90 billion capital commitment rests should be reproducible from published sources. Alto’s is not. The ninety-five-million and one-hundred-and-forty-million figures are stated in the April 2026 commentary without citation and are absent from every canonical planning document the corporation has published.

The finding does not, on its own, resolve whether the 95-million figure is defensible. It resolves whether the figure is auditable. On the public record as it stands, it is not: no derivation has been published, no methodology has been described, and no independent source has adopted it.

Three things follow

The demand case that anchors a 1,000-kilometre corridor, a $60–90 billion capital commitment, and a multi-decade delivery programme cannot responsibly rest on figures that have not been made auditable. Three steps would meet the standard.
