Canadian Active Service Force

The Canadian Active Service Force (CASF) was the field force raised by the Canadian Army in the Second World War. Legally, it was distinct from the Permanent Active Militia and the Non-Permanent Active Militia, and a soldier had to be attested for service. The CASF had its own standards for enlistment and began recruiting on 1 Sep 1939.

The term CASF was deleted in late 1940, and the term Canadian Army (Active) was used to represent full-time military units.

The Canadian Active Service Force was officially mobilized on 1 Sep 1939. The Canadian government had decided not to place the emphasis on military involvement in the Second World War on ground forces, and instead of committing to a 60,000 man Army corps, instead authorized a single division for overseas service, with a second division to be raised and kept in Canada, only to be used "if necessary."

The infantry brigades were mobilized from existing Militia units, keeping their names, badges and traditions (unlike the practice in the First World War, where Canadian Expeditionary Force units were raised as numbered battalions, often from several Militia units). All three Permanent Force regiments were represented in the order of battle of the 1st Canadian Infantry Division.

Both divisions had three infantry brigades, each with three rifle battalions and a machine gun battalion, and each brigade was organized along regional lines. This organization was changed substantially over the next two years, with the machine gun battalions being reallotted on a scale of one per division rather than one per brigade, as well as reorganization of the rifle battalions of the 5th and 6th Brigades in 1940.
