North-West Mounted Police in the Canadian north
The history of the North-West Mounted Police in the Canadian north describes the activities of the North-West Mounted Police in the North-West Territories at the end of the 19th century and the start of the 20th. The mounted police had been established to control the prairies along the Canadian-United States border in 1873, but were then also deployed to control the Yukon region during the Klondike Gold Rush, and subsequently expanded their operations into the Hudson Bay area and the far north. The force was amalgamated in 1920 to form part of the new Royal Canadian Mounted Police, who continued their predecessors' work across the region.
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.
