When did Canada enter the Second World War?
Early Years of the War (1939-1941)
When the Second World War broke out in September 1939, Canada was not yet directly involved in the conflict. However, Canada was committed to supporting Britain, which was the dominant European power at the time, through a mutual defense agreement signed in 1936.
Canada’s Response
In the early years of the war, Canada responded to Britain’s appeal for help by mobilizing its military forces, air and naval units, and increasing its industrial production. The Canadian government, led by Prime Minister William Lyon Mackenzie King, played a crucial role in mobilizing the country’s resources to support the war effort.
**Canadian military efforts began with a volunteer infantry brigade, which was formed in September 1939 and sent to Europe to fight alongside British and French forces. In the fall of 1939, the Canadian Navy began convoying ships carrying vital supplies and troops across the North Atlantic. [1]
Entry into the War
On September 10, 1940, the Canadian parliament passed the War Measures Act, which granted the government the authority to make wartime regulations and control resources. [2]
On December 6, 1941, just six days before Japan’s surprise attack on Pearl Harbor, Canada officially entered World War II, as parliament passed a motion to support Britain in the war against Germany. [3]
Why Canada Entered the War
Canada’s entry into the war was driven by a number of factors, including:
• Britain’s request for support: As Canada’s closest ally and trading partner, Canada felt a strong sense of loyalty and obligation to support Britain in its hour of need.
• German submarine attacks: Germany’s aggressive U-boat campaigns in the Atlantic were threatening British shipping lanes and disrupting trade. Canada’s entry into the war helped to shift the balance of power and secure Allied dominance in the Atlantic.
• Domestic security concerns: There were also concerns about domestic security, as some Canadians believed that Germany might launch a surprise attack on the country if it was not part of the Allied effort.
• Economic factors: The war was also a significant economic stimulus for Canada, as the government invested heavily in industrial production and infrastructure to support the war effort.

Conclusion
In conclusion, Canada’s entry into World War II was a complex and multifaceted event that was driven by a combination of factors, including Britain’s request for support, German submarine attacks, domestic security concerns, and economic factors. The country’s official entry into the war on December 6, 1941, marked the beginning of a long and difficult period of military service, industrial mobilization, and economic growth.
