The Crown acquired Rupert's Land and the North-Western Territory from the Hudson's Bay Company in 1869 (though final payment to the Hudson's Bay Company did not occur until 1870), and then transferred jurisdiction to the Dominion on July 15, 1870, merging them and naming them North-West Territories. In 1880, the British assigned all North American Arctic islands to Canada, right up to Ellesmere Island. From this vast swath of territory were created three provinces (Manitoba, Saskatchewan, Alberta) and two territories (Yukon Territory and North-West Territories, now Yukon and Northwest Territories), and two extensions each to Quebec, Ontario, and Manitoba. Later, the third territory of Nunavut was carved from the Northwest Territories on April 1, 1999. The Yukon territory was formed as this was during the Klondike gold rush. People from all around Canada and the United States flocked to the area due to rumours of unlimited gold and an easy way to get rich. The Canadian government sought to regulate this migration and tax any and all gold findings, whether American or Canadian.
