Region in Canada
The Quebec City–Windsor Corridor is the most densely populated and heavily industrialized region of Canada. As its name suggests, the region extends between Quebec City in the northeast and Windsor, Ontario, in the southwest, spanning 1,150 kilometres (710 mi). With more than 18 million people, it contains about half of the country's population, three of Canada's four largest metropolitan areas and seven of Canada's twelve largest metropolitan areas, all based on the 2016 census. Its relative importance to Canada's economic and political infrastructure renders it akin to the Northeast megalopolis in the United States. The name was first popularized by Via Rail, which runs frequent passenger rail service in the region in its service area known as The Corridor.
