The First Canadian Army was a field army and a formation of the Canadian Army in World War II in which most Canadian elements serving in North-West Europe were assigned. It served on the Western Front from July 1944 until May 1945.

The unnumbered Canadian Corps was the first corps-level military formation established by the Canadian Army during the Second World War between late 1940 and mid-1942. A four-division Canadian Corps had existed during the First World War. However, during World War II Canada's military contribution was to increase to the scale of a five-division, two-corps army and the formation was eventually redesignated as I Canadian Corps on April 6, 1942.
