The Inuvialuit Settlement Region, located in Canada's western Arctic, was designated in 1984 in the Inuvialuit Final Agreement by the Government of Canada for the Inuvialuit. It spans 435,000 km (270,000 mi), including 90,650 km2 (35,000 sq mi) of land and 12,980 km2 (5,010 sq mi) of subsurface mineral rights. The ISR is mainly North of the tree line, and includes several sub-regions: the Beaufort Sea, the Mackenzie River delta, the northern portion of Yukon, and the northwest portion of the Northwest Territories. The ISR includes both Crown Lands and Inuvialuit Private Lands. Most of the ISR is represented by Nunakput, the territorial electoral district, meaning "our land" in Inuvialuktun.
