North-Western Territory
After the 1870 transfer, some of the North-West Territories was whittled away. The province of Manitoba was enlarged in 1881 to a rectangular region composing the modern province's south. By the time British Columbia joined Confederation on July 20, 1871, it had already (1866) been granted the portion of North-Western Territory south of 60 degrees north and west of 120 degrees west, an area that comprised most of the Stickeen Territories.
