Named Alto, Canada’s new $3.9B high-speed rail line will run from Toronto to Québec City, with speeds forecast at up to 300 km/h, the federal government has announced.

MONTREAL — A high-speed rail link between Toronto and Quebec City could deliver billions of dollars in economic benefits, a new report says. The C.D. Howe Institute study found that the promised line would generate between $15 billion and $27 billion in value for Canadians over six decades.

The Liberal government launched a six-year, $3.9-billion design and development plan Wednesday that Prime Minister Justin Trudeau says will eventually connect Quebec City and Toronto with a high-speed rail line.
