Dominion Police
The Dominion Police, although the federal police of Canada, was mainly active in the Eastern Canada region, while the Royal Northwest Mounted Police handled the expansive and sparsely populated Northwest Territories of Western Canada. In May 1918, the 969-member Dominion Police was reassigned under the Department of Militia and Defence and became a civilian wing of the Canadian Military Police Corps (CMPC). In the early 1900s, the Royal Northwest Mounted Police had declined as the Northwest Territories was divided into new provinces and territories, and due to the general unpopularity of the force for conduct during industrial disputes such as the Winnipeg General Strike. On 1 February 1920, the civilian members of the CMPC, including the Dominion Police, were merged with the Royal Northwest Mounted Police to form the Royal Canadian Mounted Police as the new federal police force of Canada, and the CMPC was disbanded on 1 December 1920.
State police
The Royal Canadian Mounted Police (RCMP) provides provincial-level policing in the remaining land area of Newfoundland and Labrador, as well as the remaining 7 provinces and 3 territories of Canada. The RCMP began being contracted to provide provincial policing in the late 1920s as provincial police forces were disbanded and their duties inherited by provincial divisions of the RCMP. The last provincial police force to be disbanded, the British Columbia Provincial Police, existed from the mid-19th century until it was incorporated into RCMP "E" Division on August 15, 1950.
