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. On 1 February 1920, the Dominion Police was merged with the North-West Mounted Police to form the Royal Canadian Mounted Police as the new federal police force of Canada.
Royal Military Police
The RMP's origins can be traced back to the 13th century but it was not until 1877 that a regular corps of military police was formed with the creation of the Military Mounted Police, which was followed by the Military Foot Police in 1885. Although technically two independent corps, they effectively functioned as a single organisation. In 1926, they were fully amalgamated to form the Corps of Military Police (CMP). In recognition of their service in the Second World War, they became the Corps of Royal Military Police (RMP) on 28 November 1946.
