3 Military Police Regiment (Canada)
The Military Police in Halifax trace their roots back to World War I where, in 1917, the Canadian Military Police Corps (CMPC) was stood up and Number 6 Detachment was formed. Their main duty was to maintain discipline, enforce the Conscription Act, and apprehend deserters and draft evaders. The CMPC was stood down in 1920.
