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 Canadian Mounted Police
Prime Minister Sir John A. Macdonald first began planning a permanent force to patrol the North-West Territories after the Dominion of Canada purchased the territory from the Hudson's Bay Company. Reports from Army officers surveying the territory led to the recommendation that a mounted force of between 100 to 150 mounted riflemen could maintain law and order. The Prime Minister first announced the force as the "North West Mounted Rifles". However, officials in the United States raised concerns that an armed force along the border was a prelude to a military buildup. Macdonald then renamed the force the North-West Mounted Police (NWMP) when formed in 1873.
