What evidence is there that Canada responded quickly to Britain's call for help?

Canada demonstrated its quick response to Britain's call for help during World War I by enacting the Military Service Act in 1917, which authorized conscription to bolster its military ranks. Additionally, the Canadian Expeditionary Force was mobilized rapidly, with over 600,000 Canadians serving overseas by the war's end. The country also contributed significantly to key battles, such as Vimy Ridge in 1917, showcasing its commitment to the British war effort. These actions highlight Canada's immediate and robust support in times of need.
