<p>Map of the provinces and territories of Canada as they were between 1905 and 1912. On September 1 1905, Alberta and Saskatchewan were created from parts of the North-West Territories and the District of Keewatin; the remainder of the District of Keewatin was remerged into the North-West Territories. On May 15 1912, parts of the North-West Territories were given to Manitoba, Ontario, and Quebec. Also note that in 1912, the official name dropped the hyphen, changing to "Northwest Territories".
