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 Canadian government says it is moving ahead with a multi-billion dollar plan to build a high-speed rail network between Quebec City and Toronto

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.
