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.
North-West Mounted Police
The North-West Mounted Police (NWMP) was a Canadian police force, established in 1873 by the Prime Minister, Sir John Macdonald, to maintain order in the North-West Territories. The mounted police combined military, police and judicial functions along similar lines to the Royal Irish Constabulary, and deployed the following year to the Alberta border in response to the Cypress Hills Massacre and subsequent fears of a United States military intervention. Their ill-planned and arduous journey of nearly became known as the March West and was portrayed by the force as an epic journey of endurance. Over the next few years, the police extended Canadian law across the region, establishing good working relationships with the First Nations. The force formed part of the military response to the North-West Rebellion in 1885, but faced criticism for their performance during the conflict.
