The submachinegun was the primary weapon carried by Canadian MPs in the field and by the late 1950s, World War 2 vintage Sten submachineguns were replaced by the SMG C1. The SMG C1 was a "Canadianised" version of the British Patchett Stirling SMG. It was manufactured by Canadian Arsenals Ltd at Long Branch, a suburb of Toronto Ontario. The standard magazine held 30 rounds, and a 10 round magazine was provided for use by vehicle crews. The SMG was selective fire and had a 100 and 200 yard aperature rear sight. It had a folding stock and was fitted for the standard Canadian C1 rifle bayonet. The SMG C1 was very popular and was considered one of the best of it's type in the world. It remained in service until the mid 1980s, when it was withdrawn and placed in war reserve stock.
The primary pistol in use by Provost and later, Canadian Military Police, from 1944 until the mid 1990s was the 9 mm Browning Hi Power. It's magazine was capable of holding 13 rounds, but was normally only loaded with 10. A big advantage was that it fired the same ammunition as the SMG C1.
