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.

The force controlled postwar unrest. Perry was a principal adviser to the government during the Winnipeg General Strike in 1919. 
After the war, he reorganized the force as the Royal Canadian Mounted Police. By modernizing the force's equipment and methods, he transformed the frontier police to a modern national police force. In 1919, he worked out the details of the force's expansion and the move of its headquarters. The Force absorbed the Dominion Police, extended police services throughout Canada and moved headquarters from Regina, Saskatchewan, to Ottawa, Ontario. The Force emerged as the Royal Canadian Mounted Police in 1920.
By February 1, 1920, the Royal Canadian Mounted Police were operating throughout Canada. Perry retired from the Royal Canadian Mounted Police in 1923. He was conferred the equivalent military rank of major-general. He died in Ottawa, Ontario, on February 14, 1956, in his 96th year. He was the last surviving member of the "Old Eighteen" from Royal Military College of Canada.
