The Canadian government is moving ahead with a multibillion-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.

If it does happen, a high-speed rail line could mean a trip between Montreal and Toronto would take less than three hours, far shorter than the current trip on Via Rail or by car — and in some cases quicker than a flight, after taking into account the trip to the airport and passing through security.
