In what year did Canada become a country?

Canada became a country on July 1, 1867, when the British North America Act (now known as the Constitution Act, 1867) came into effect, uniting the three separate colonies of the Province of Canada, Nova Scotia, and New Brunswick into a single Dominion within the British Empire called Canada. This act laid the foundation for Canada's parliamentary system and established its federal structure, marking a significant milestone in the country’s evolution from a British colony to an independent nation.

The other years listed are significant in their own rights but do not represent the date of Canada’s confederation. For instance, 1776 is notable for the American Declaration of Independence, and while it marked the start of a significant shift in the North American landscape, it is unrelated to Canada’s formation. The year 1905 is when Alberta and Saskatchewan were established as provinces, which occurred after Canada had already become a country. Lastly, 1931 is when the Statute of Westminster was enacted, providing full legislative independence to Canada from Britain, but this happened long after Canada had already been formed as a nation. Collectively, these aspects highlight the importance of 1867 as the correct answer, as it signifies the birth of Canada as a unified nation
