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 force added "Royal" to its name in 1904. It merged with the Dominion Police, the main police force for all points east of Manitoba, in 1920 and was renamed as the "Royal Canadian Mounted Police". The new organization was charged with federal law enforcement in all the provinces and territories, and immediately established its modern role as protector of Canadian national security, as well as assuming responsibility for national counterintelligence.
