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
The Royal Canadian Mounted Police (RCMP; , "Royal Gendarmerie of Canada"; colloquially known as The "Mounties", and internally as "the Force") is the federal and national police force of Canada. The RCMP provides law enforcement at the federal level. It also provides provincial policing in eight of Canada's provinces (Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Prince Edward Island, and Saskatchewan) and local policing on contract basis in the three territories (Northwest Territories, Nunavut, and Yukon) and more than 150 municipalities, 600 aboriginal communities, and three international airports. The RCMP does not provide provincial or municipal policing in either Ontario or Quebec.
