was canada part of the british empire during ww2
When the United Kingdom declared war on Nazi Germany at the outset of World War II it controlled to varying degrees numerous crown colonies, protectorates and the Indian Empire. It also maintained unique political ties to four semi-independent Dominions--Australia, Canada, South Africa, and New Zealand--as part of the Commonwealth. In 1939 the British Commonwealth was a global superpower, with direct or de facto political and economic control of 25% of the world's population, and 30% of its land mass.
