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.
1st Battalion, Canadian Mounted Rifles, CEF
The 1st Battalion, Canadian Mounted Rifles, CEF, was an infantry unit of the Canadian Expeditionary Force in the First World War. Originally a mounted infantry unit named the 1st Regiment, Canadian Mounted Rifles, CEF, it was formed on November 7, 1914, in Brandon, Manitoba. Part of the 1st Brigade Canadian Mounted Rifles, the unit landed in France on September 22, 1915, where the conditions of the Western Front made its mounts more of a hindrance than a benefit.
On January 1, 1916, both CMR brigades (six regiments) were dismounted, converted to infantry and reorganized as the 8th Infantry Brigade (four battalions). The 1st Regiment, CMR, became the 1st Battalion, CMR, and it absorbed half the personnel of the 3rd Regiment, CMR (the other half going to the 2nd Battalion, CMR).
