Police
In Canada, the Royal Newfoundland Constabulary was founded in 1729, making it the first police force in present-day Canada. It was followed in 1834 by the Toronto Police, and in 1838 by police forces in Montreal and Quebec City. A national force, the Dominion Police, was founded in 1868. Initially the Dominion Police provided security for parliament, but its responsibilities quickly grew. The famous Royal Northwest Mounted Police was founded in 1873.
The merger of these two police forces in 1920 formed the world-famous Royal Canadian Mounted Police.
Aylesworth Bowen Perry
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.
