In which year did Canada officially become a country?

Canada officially became a country in 1867 with the confederation of the British North American colonies of Ontario, Quebec, New Brunswick, and Nova Scotia. This pivotal moment in Canadian history is marked by the passage of the British North America Act (now known as the Constitution Act, 1867), which united these provinces into a single Dominion within the British Empire. On July 1, 1867, Canada established its own governance and began to chart its path as an independent nation.

The other years mentioned have historical significance in Canada, such as 1871, when British Columbia joined Confederation, or 1905, which saw Saskatchewan and Alberta becoming provinces. However, it was in 1867 that Canada first became a unified country, marking its birth as a nation.
