Non-Permanent Active Militia
The Non-Permanent Active Militia (NPAM) was the name of Canada's part-time volunteer military force from the time of Confederation to 1940. The NPAM (also called "the Militia" though that term could also encompass the full-time standing army known as the Permanent Active Militia (PAM)) was composed of several dozen infantry battalions (redesignated as regiments in 1900) and cavalry regiments. With the withdrawal of the British forces in Canada after the turn of the 20th century, supporting corps were created in Canada as part of both the PAM and the NPAM.
The NPAM did not mobilize during the First World War, though large drafts of NPAM men went into the field force created in 1914 for that conflict, the Canadian Expeditionary Force. Some CEF units adopted regimental traditions from NPAM units. Following the war, the Otter Committee created a unique set of perpetuations, whereby the reorganized NPAM carried on the traditions of both the CEF and the prewar Militia in the Canadian Militia.
In 1940, the NPAM was redesignated the Canadian Army (Reserve); following the Second World War it was redesignated the Canadian Army Reserve Force, then the Canadian Army (Militia), and finally became the reserve component of Force Mobile Command following Unification on February 1, 1968. However, the historic title "Militia" continued to be applied to the reserve component of Canada's land forces.
