What year did Canada enter World War II?

Canada entered World War II on September 10, 1939. This was a significant moment in Canadian history, as the country declared war on Germany following the British declaration on September 3, 1939. Canada's involvement marked a shift from the policies of isolationism that characterized the interwar years. By entering the war at this time, Canada demonstrated its commitment to supporting its allies and fighting against fascism.

The year is crucial not only because it aligns with the global timeframe of the war but also because it reflects Canada's growing independence in foreign policy decisions. The other years listed do not correlate with Canada’s official entry into the conflict, as 1941 represents the period when the United States joined the war, 1945 marks the end of the war, and 1936 is before the war began.
