Final answer:
Canada was automatically at war with Germany when Great Britain declared war in both World War I and II, due to its status as part of the British Empire, making the claim that Canada declared war two weeks after Britain false.
Step-by-step explanation:
The statement that Canada declared war on Germany two weeks after Great Britain is false. As part of the British Empire at the start of World War I, when Britain declared war on Germany on August 4, 1914, Canada was automatically considered to be at war as well. The Canadian military, initially small and voluntary, quickly expanded as 33,000 Canadians arrived in Britain for training by the fall of 1914. In the period leading up to and during World War II, following the invasion of Poland, France and Great Britain declared war on Germany on September 3, 1939, but direct conflict did not immediately begin, leading to a period known as the "Phony War".
