Dominion Police
The Dominion Police Force was the federal police force of Canada between 1868 and 1920, and was one of the predecessors of the Royal Canadian Mounted Police. It was the first federal police force in Canada, formed the year following the Canadian Confederation to enforce federal laws and perform policing duties for the Federal Government of Canada.

Canadian Provost Corps
At the outbreak of World War II, the Canadian Army was without any form of military police. On September 13, 1939, the Royal Canadian Mounted Police (RCMP) requested and received permission to form a Provost Company using volunteers from its ranks. This was designated 1 Provost Company (RCMP), of the 1st Canadian Infantry Division, Canadian Active Service Force. Initially, it was 120 men; many of them were in the UK by the end of 1939.
