Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, making it the world's second-largest country by total area, with the world's longest coastline. Its border with the United States is the world's longest international land border. The country is characterized by a wide range of both meteorologic and geological regions. It is a sparsely inhabited country of 40 million people, the vast majority residing south of the 55th parallel in urban areas. Canada's capital is Ottawa and its three largest metropolitan areas are Toronto, Montreal, and Vancouver.

Canada ranks 37th by population among countries of the world, comprising about 0.5% of the world's total, with more than 40 million Canadians as of 2024. Despite being the second-largest country by total area, the vast majority of the country is sparsely inhabited, with most of its population south of the 55th parallel north. Just over 60 percent of Canadians live in just two provinces: Ontario and Quebec. Though Canada's overall population density is low, many regions in the south, such as the Quebec City–Windsor Corridor, have population densities higher than several European countries. Canada has six population centres with more than one million people: Toronto, Montreal, Vancouver, Calgary, Edmonton and Ottawa.
