In recent years, Canada’s Alto High-Speed Rail programme has transitioned from concept to a structured delivery phase. As outlined during the US High Speed Rail Conference, the initiative is now in early development following federal approval, with construction set to begin as early as 2029.
The programme aims to connect Toronto, Ottawa, Montreal, and Quebec City along a roughly 1,000-kilometre corridor, serving a population of approximately 18 million people in Canada’s most economically active region. Designed for speeds of up to 300 km/h, the system is expected to cut travel times roughly in half, reducing Toronto–Montreal journeys to under three hours and Toronto–Ottawa to under two.
With speeds reaching 300 km/h or more on approximately 1,000 km of dedicated and mainly electrified tracks, Alto will connect millions of people living along the Toronto–Québec City corridor

At the USHSR Conference, the project’s progress was presented by Karla Avis-Birch at Arup, Maria Luisa Dominguez from ALTO, and Clémentine Sallée representing CDPQ Infra and Cadence. The speakers highlighted the programme’s move from planning to execution under a structured delivery partnership.
The Crown corporation, Alto, is leading the programme, supported by a private-sector consortium, Cadence, with infrastructure and mobility specialists, such as CDPQ Infra, and engineering advisors, such as Arup. This structure reflects a deliberate “co-development” model, where design, risk assessment, and market engagement are advanced in parallel rather than sequentially. This approach is allowing multiple alignment options to be developed simultaneously, enabling the government to select the optimal solution based on cost, performance, and constructability.
Maria Luisa Domínguez (ALTO – Canada) said:
Before making the decision of building the first high-speed line, a lot of discussions and technical and economic studies happen. That’s normal. But on February 19, 2025, everything changed when the Government of Canada announced it was moving forward with Alto, Canada’s first high-speed line between Toronto, Ottawa, Montreal and Quebec City, covering more or less a thousand kilometres of track. It is going to be one of the largest infrastructure initiatives in the recent history of the country.
One of the most advanced elements of the programme to date has been its public consultation process, described as the largest in Canada’s history for a transport project. More than 10,000 Canadians participated in in-person and virtual sessions, generating approximately 19,000 pieces of feedback. Early results indicate approximately 69% public support, though concerns remain around land use, station placement, and property impacts.
The corridor design is currently defined within a broad 10-kilometre study area, which will progressively be narrowed to an approximate 60-metre operational footprint as alignment decisions are refined. The first construction segment is expected to focus on the Ottawa–Montreal corridor, selected due to its shorter length and strategic value as a ‘learning segment’ to refine delivery methods before scaling to the full network.
The programme is currently estimated at up to 90 billion CAD over an 18-year delivery horizon, with projections suggesting it could create up to 50,000 construction jobs and 5,000 long-term operational roles. However, the speakers emphasised that these figures remain under active refinement as alignment and technical studies continue.
Indeed, a key theme throughout the discussion was the importance of cost certainty without premature commitment. Instead of locking in fixed figures early, Alto is using market sounding, geotechnical investigations, and iterative design to progressively ‘de-risk’ the programme before procurement decisions are finalised.
Clementine Sallée (CDPQ Infra / Cadence) said:
One of our main goals is to translate project outcomes into a manageable and reliable system, meaning safety, passenger experience, affordability and value for money. We are not transferring risk at this stage — we are de-risking the execution phase. This is about identifying and evaluating risks early, testing them with the market, and ensuring that when we allocate them later, we do so with the best possible information.
Governance of the programme has been structured around frequent, multi-layered decision-making forums, ranging from weekly technical working groups to monthly leadership boards. Decisions are taken collaboratively under a unified governance framework designed to avoid bottlenecks while ensuring accountability between the Crown corporation and its delivery partners. Domínguez stressed that this combination of both internal and external governance is key to resolving contradictions between provinces and ensuring the most effective decisions can be made.
Notably, Sallée also intentionally framed Alto as a programme rather than a single project. This distinction allows the corridor to be broken into multiple segments and packages, enabling staggered procurement, continuous mobilisation of the supply chain, and phased delivery. This segmentation strategy is likewise intended to manage complexity across jurisdictions, particularly as the route spans multiple provinces and requires coordination with federal, provincial, and Indigenous stakeholders.
While major uncertainties remain, including final alignment, station placement, land acquisition strategies, and total cost, project leaders emphasised that the current phase is deliberately designed to resolve these questions before construction begins. Currently, the focus lies in aligning technical design with public consultation outcomes, market capacity, and long-term operational performance.
Alto thus remains in a critical transition period, moving from political commitment to engineering definition, and from early planning to structured execution.
