The Canadian Provost Corps was the military police corps of the Canadian Army. The Canadian Provost Corps was authorized on 15 June 1940. The Canadian Provost Corps was amalgamated with the police forces of the Royal Canadian Navy and Royal Canadian Air Force to become a new, unified branch of the Canadian Forces in 1968, known as the Canadian Armed Forces Security and Intelligence Branch.

Corps is a term used for several different kinds of organization. A military innovation by Napoleon I, the formation was first named as such in 1805. The size of a corps varies greatly, but two to five divisions and anywhere from 40,000 to 80,000 are the numbers stated by the US Department of Defense.
