The 2nd Canadian Division, an infantry division of the Canadian Army, was mobilized for war service on 1 September 1939 at the outset of World War II. Adopting the designation of the 2nd Canadian Division, it was initially composed of volunteers within brigades established along regional lines, though a halt in recruitment in the early months of the war caused a delay in the formation of brigade and divisional headquarters. With questions concerning overseas deployment resolved, the division's respective commands were formed in May and June 1940, and at British Prime Minister Winston Churchill's request, the division was deployed to the United Kingdom between 1 August and 25 December 1940, forming part of the Canadian Corps.

Operation Jubilee or the Dieppe Raid was an unsuccessful Allied amphibious attack on the German-occupied port of Dieppe in northern France, during the Second World War. Over 6,050 infantry, predominantly Canadian, supported by a regiment of tanks, were put ashore from a naval force operating under protection of Royal Air Force (RAF) fighters.
