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.
Royal Canadian Mounted Police
The Royal Canadian Mounted Police (RCMP; , "Royal Gendarmerie of Canada"; colloquially known as The "Mounties", and internally as "the Force") is the federal and national police force of Canada. The RCMP provides law enforcement at the federal level. It also provides provincial policing in eight of Canada's provinces (Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Prince Edward Island, and Saskatchewan) and local policing on contract basis in the three territories (Northwest Territories, Nunavut, and Yukon) and more than 150 municipalities, 600 aboriginal communities, and three international airports. The RCMP does not provide provincial or municipal policing in either Ontario or Quebec.
