Province of Buffalo

Its main proponent was Sir Frederick Haultain, the premier of the North-West Territories.

However, Haultain's frosty relations with Canadian Prime Minister Sir Wilfrid Laurier did not help his cause, and in 1905, his proposed province was divided into Alberta in the west and Saskatchewan in the east.

The Province of Buffalo was one of several proposals for the area of what would become Alberta and Saskatchewan.

Laurier eventually decided to carve two provinces out of that section of the North-West Territories by dividing the land up with a north–south line.

In 2005 Canadian Geographic magazine ran a cover story, "How the West was divided", on Haultain's proposal.
