North-West Territories
The boundaries of the region were subject to frequent change. The region north and sometimes east of Manitoba was established as the District of Keewatin in 1876. The boundaries of Manitoba were changed in 1877, and enlarged in 1881 and 1912. Yukon Territory was created in 1898; and the provinces of Alberta and Saskatchewan created in 1905. Internally, 4 administrative districts were created in 1882: Assiniboia, Saskatchewan, Alberta and Athabaskan. It was into these districts, in the Southern portion of the Territories, that the great bulk of the settlement population would flow, and consequently on which most government attention was focused prior to 1905.
