Answer and Explanation:
The main motivation for Canada's entrance into World War I was its close relationship with the British Empire.
As a member of the British Empire, Canada had strong political, economic, and cultural ties to Britain. When Britain declared war on Germany in 1914, Canada felt obligated to support its ally and contribute to the war effort. The belief in the defense of shared values, such as democracy and the rule of law, also played a role in motivating Canada to enter the war.
Additionally, Canada had its own interests at stake. Many Canadians saw the war as an opportunity to assert their nationhood and demonstrate their loyalty to the Empire. There was also a desire to protect Canada's own territorial interests and ensure the security of its borders.
The Canadian government actively promoted recruitment efforts and encouraged citizens to enlist in the Canadian Expeditionary Force. Thousands of Canadians answered the call to serve and fought alongside British and Allied forces on the Western Front.
In summary, Canada's main motivation for entering World War I was its close alliance with the British Empire, along with a desire to defend shared values and protect its own interests.
