The Quebec City–Windsor Corridor (French: Corridor Québec-Windsor) is the most densely populated and heavily industrialized region of Canada. As its name suggests, the 1,150 km (710 mi)-long region extends from Quebec City in the northeast to Windsor, Ontario in the southwest. With more than 18 million people, it contains about half of the country's population and seven of Canada's 12 largest metropolitan areas, 3 of which are in the top 4 (based on the 2021 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".
