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.
