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.
Canadian Army
Prior to Confederation in 1867, the British Army, which included both "Fencible" Regiments of the British Army—recruited within British North America exclusively for service in North America—and Canadian militia units, was responsible for the defence of Canada. Some current regiments of the Canadian Army trace their origins to these pre-Confederation militia and Fencible units. Following the passage of the "Militia Act of 1855", the Permanent Active Militia was formed, and in later decades several regular bodies of troops were created, their descendants becoming the Royal Canadian Horse Artillery, the Royal Canadian Dragoons, and the Royal Canadian Regiment. Regular Canadian troops participated in the North West Rebellion in 1885, the South African War (Second Boer War) in 1899, and, in much larger numbers, constituted the Canadian Expeditionary Force in First World War.
