The Parliamentary Budget Office reports that the Alto high-speed rail project between Toronto and Quebec City could cost between $75 billion and $113 billion, surpassing initial estimates of $60 to $90 billion. The higher costs are attributed mainly to tunneling and elevated structures, with each additional kilometer adding significant expenses. The report also notes that including a potential stop in Kingston adds uncertainty due to mixed construction challenges and environmental factors.

Story summary
The Parliamentary Budget Office (PBO) released a report on Thursday indicating that the cost of building a high-speed rail line between Toronto and Quebec City, known as the Alto project, could range from $75 billion to $113 billion. This estimate exceeds the federal government's previous projection of up to $90 billion. The PBO noted that adding a stop in Kingston, Ont. would increase uncertainty due to easier construction but higher population density and ecological sensitivity. The project aims to connect Toronto and Montreal within approximately three hours, aiming to revitalize transportation infrastructure but raising concerns about the growing national debt under Prime Minister Mark Carney's administration.

Alto high-speed rail project likely to cost more than originally thought: budget watchdog
New report says Toronto-Quebec City corridor project could between $75B to $113B
Building the proposed high‑speed rail project between Toronto and Quebec City could cost between $75 billion and $113 billion — higher than the official initial estimates, according to a new report from the Parliamentary Budget Office.
Following a request from the House of Commons' finance committee, the federal budget watchdog released a report on Thursday trying to put a dollar figure on the government's controversial Alto high-speed rail corridor, which promises to connect Toronto and Montreal in about three hours.

Alto, the Crown corporation responsible for the major infrastructure project, is also looking at a potential stop in Kingston, Ont.

The Parliamentary Budget Office said based on analysis of international construction experience and assumed characteristics of the proposed Canadian route, the baseline route, excluding Kingston, could cost between approximately $75 billion and $113 billion to construct.

The main drivers of the cost are the tunnels and elevated structures used in the project.

The budget watchdog said international evidence indicates that each additional kilometre of tunnel will add $169 million to the total cost of this project, while an additional kilometre of elevated structures will add $153 million.

Adding a stop in Kingston, Ont., is expected to increase uncertainty, the report notes, "due to the counter-balancing effects of easier geography for construction, but higher density of regional populations and greater ecological sensitivity."
