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.
Rocky Mountain Rangers (1885)
The Rocky Mountain Rangers were one of the volunteer militia units raised in Canada's North West in response to the 1885 North-West Rebellion. It was a body of mounted irregulars, mostly cowboys and ranchers from the area around Fort Macleod (District of Alberta), the headquarters of the North-West Mounted Police (NWMP) located at the base of the foothills of the Rocky Mountains, about west of Medicine Hat (in what was then the District of Assiniboia). This unit is not to be confused with the present-day Canadian Army Reserve unit The Rocky Mountain Rangers of Kamloops, British Columbia. Rather, it is the ultimate ancestor of the South Alberta Light Horse.
