Northwest Territories (electoral district) Northwest Territories (electoral district) Northwest Territories () is a federal electoral district represented in the House of Commons of Canada. This riding was created in 1962 from Mackenzie River riding. It was composed of the entire territory of the Northwest Territories. In 1979, the riding was divided into the ridings of Western Arctic and Nunatsiaq (later Nunavut). Following the creation of the territory of Nunavut in 1999, the riding of Western Arctic was made coterminous with the new Northwest Territories. After 1999, Western Arctic was an anomaly in that, unlike Nunavut and Yukon, it did not share the name of
British Arctic Territories the Province of Manitoba and the new Northwest Territories, which originally included northern Ontario, the rest of Manitoba, all of Saskatchewan and part of Alberta, and what is now Nunavut territory, with the name Northwest Territories retained by the successor government in the region flanked by the Mackenzie River drainage to the north of Alberta. The North-Western Territory was to its northwest, and included parts of British Columbia north of the Stikine Territory and including all of today's Yukon territory, and parts of Alberta not in the Hudson Bay drainage, as well as today's Northwest Territories.
