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.
North-West Mounted Police
Sir John Macdonald acquired approval for his new force on May 23, 1873, after Parliament, following a cursory debate, passed the Mounted Police Act into law unopposed. At this point, Macdonald appears to have intended to create a force of mounted police to watch "the frontier from Manitoba to the foot of the Rocky Mountains", probably with its headquarters in Winnipeg. He was heavily influenced by the model of the Royal Irish Constabulary, which combined aspects of a traditional military unit with the judicial functions of the magistrates' courts, and believed that the new force should be able to provide a local system of government in otherwise ungoverned areas. Originally, Macdonald also had wanted to form units of Métis policemen, commanded by white Canadian officers in a similar manner to the British Indian Army, but he was forced to abandon this approach after the Métis revolt of 1870 called their loyalty into question.
