Oh Canada. It was on Sept. 1, 1905 that the districts of Alberta and Saskatchewan were split from the Northwest Territories became full-fledged provinces.
The southern border of the provinces once belonged to the United States as they were part of the Louisiana Purchase. They were traded in 1818 for parts of Rupert’s Land which include large parts of North Dakota and Minnesota. The treaty established the 49th parallel east of the Continental Divide the boundary of Canada and the United States.
