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.
Canadian Forces Military Police
The first embassy to employ MP personnel as Military Security Guards was Beirut, Lebanon in 1976. The Military Security Guard Unit (MSGU) was declared an official unit of the CF in 1990, and was officially renamed the MPSS in 2009.Originally established as one of several military detention centres, the CFSPDB, located at CFB Edmonton, is now the sole, permanently established military corrections facility remaining in the CF. The roles of the CFSPDB include: provide imprisonment and detention services for Canadian Forces service detainees, service prisoners and service convicts; to adjust detainees and prisoners to service discipline, and prepare them to resume an effective role in the CF; to return prisoners to civilian life, where appropriate, with improved attitude and motivation; and to provide subject matter expertise and guidance in support of Canadian Forces disciplinary programs and deployed prisoner of war/detainee operations.
