From 1921 to 1931, Armistice Day (later renamed Remembrance Day) and Thanksgiving were marked on the same date. The two events were then separated, but the timing of Thanksgiving varied.
In 1957, the second Monday of October was set as the consistent date for Thanksgiving Day in Canada.
In 2012, Canadians consumed 142 million kilograms (312.4 million pounds) of turkey or 4.1 kilograms (nine pounds) per capita.
