When did Canada join World War II?
Canada’s decision to enter World War II was a significant turning point in the country’s history. The war had already been raging in Europe and Asia for over two years when Canada finally declared war on Germany and Italy.
The Initial Neutrality
Canada declared war on Germany on September 10, 1939, just days after the invasion of Poland, which marked the beginning of World War II. The Canadian government, led by Prime Minister William Lyon Mackenzie King, initially maintained a policy of neutrality, adopting a stance of "conditional neutrality" that allowed it to provide limited support to France and the United Kingdom, while avoiding direct involvement in the conflict.
German Invasion of Poland
Germany’s invasion of Poland on September 1, 1939, set off a chain reaction of military mobilizations across Europe and North America. The attack prompted the United Kingdom to declare war on Germany, and Canada, following the British lead, gave its support to the British Crown.
Canada’s Neutrality is Tested
In the months that followed, Canada’s neutrality was tested as the country watched the war unfold in Europe. The government faced criticism from both pro-British and pro-German groups, with some advocates for neutrality arguing that entering the war would lead to economic and social instability in Canada.
The French Defeat
The turning point came in June 1940, when France fell to Germany and the British Expeditionary Force was forced to evacuate from Dunkirk. This outcome led to a significant shift in Canadian public opinion, with many Canadians coming to see the war as an existential threat to the security of the British Empire, and by extension, to Canada itself.
Pearl Harbor and the Outbreak of War in Asia
The surprise attack by Japan on December 7, 1941, on the United States naval base at Pearl Harbor, drew Canada into the war in Asia. Although Canada had already declared war on Germany and Italy in 1939, its military efforts had been primarily focused on supporting the Allied war effort in Europe. The attack on Pearl Harbor led to a significant change in Canada’s military priorities, with the country joining the United States in battling Japan in the Pacific theatre.
Canada’s Commitment to the War
In the months that followed, Canada’s commitment to the war effort grew steadily. The country’s Parliament passed a series of measures authorizing the government to provide financial and military support to the Allies, and in 1942, a Canadian Expeditionary Force (CEF) was established, with the goal of recruiting and training a large, modern army.

Conclusion
In summary, Canada joined World War II on September 10, 1939, when it declared war on Germany and Italy in response to the invasion of Poland. The country initially maintained a policy of neutrality, but as the war dragged on and the threat from Germany and Japan grew, Canada’s commitment to the war effort grew steadily, culminating in the formation of a large, modern army and significant military operations in both Europe and Asia.
