North-Western Territory
From the 18th century, the territory was claimed by the British, with portions of Nunavut administered as a part the Rupert's Land, the North-Western Territory, or the British Arctic Territories. After the Deed of Surrender was signed in 1870, ownership of Rupert's Land and the North-Western Territory was transferred from the Hudson's Bay Company to the government of Canada. In 1880, the British Arctic Territories were also transferred to the Canadian government. Present-day Nunavut was initially administered as a part of the Northwest Territories, although by the end of 1912, the territory only administered the lands north of the 60th parallel north and east of Yukon.
