northern Manitoba, and mainland Nunavut. The government of Keewatin was based in Winnipeg, Manitoba. The territory did not have any representation in federal parliament. Population The vast majority of Canada's population is concentrated in areas close to the Canada–US border. Its four largest provinces by area (Quebec, Ontario, British Columbia and Alberta) are also (with Quebec and Ontario switched in order) its most populous; together they account for 86% of the country's population. The territories (the Northwest Territories, Nunavut and Yukon) account for over a third of Canada's area but are only home to 0.3% of its population, which skews the national population density value. Canada's population grew by 5.0% between the 2006 and 2011 censuses. Except for New Brunswick, all territories and provinces increased in population during this time. In terms of percent change, the fastest-growing province or territory was Nunavut with an increase of 12.7% between 2011 and 2016, followed by Alberta with 11.6% growth, while New Brunswick's population decreased by 0.5%. Generally, Canadian provinces have steadily grown in population along with Canada. However, some provinces such as Saskatchewan, Prince Edward Island and Newfoundland and Labrador have experienced long periods of stagnation or population decline. Ontario and Quebec have always been the two biggest provinces in Canada, with together over 60% of the population at any given time. The population of the West relative to Canada as a whole has steadily grown over time, while that of Atlantic Canada has declined. Territorial evolution Ontario, Quebec, New Brunswick, and Nova Scotia were the original provinces, formed when several British North American colonies federated on July 1, 1867, into the Dominion of Canada and by stages began accruing the indicia of sovereignty from the United Kingdom. Prior to this, Ontario and Quebec were united as the Province of Canada. Over the following years, Manitoba (1870), British Columbia (1871), and Prince Edward Island (1873) were added as provinces. The British Crown had claimed two large areas north-west of the Canadian colony, known as Rupert's Land and the North-Western Territory, and assigned them to the Hudson's Bay Company. In 1870, the company relinquished its claims for £300,000 (CND$1.5 million), assigning the vast territory to the government of Canada. Subsequently, the area was re-organized into the province of Manitoba and the North-West Territories. The North-West Territories encompassed all of current northern and western Canada, except for the British holdings in the Arctic islands
