In early 1918, the Canadian Food Board became responsible for monitoring Canada’s food production and management during the war effort. Following Great Britain’s example, government programs, news publications and propaganda posters encouraged voluntary rationing, such as “meatless Fridays”, and ingredient substitution in everyday recipes.
By 1918, Great Britain was pushed to enact compulsory rationing, after nearly a year on voluntary rationing (since February 1917). To combat misuse and the breaching of ration orders, stiff punishments were also introduced.
As Germany’s unrestricted submarine warfare continued late into the war, the threat to Great Britain’s food supply had continued to mount. In April 1917, the nation’s wheat supply had fallen to just six weeks’ worth (Morrow, The Great War: An Imperial History, p. 202). In the spring of 1918, the British would launch an audacious raid to combat the German submarine threat.
