On July 1, 1867, the British North America Act came into effect, uniting the three separate colonies of the Province of Canada, New Brunswick, and Nova Scotia into a single Dominion within the British Empire called Canada. This day, now celebrated as Canada Day, marked the birth of Canada as a nation, with its own government and constitution, albeit still a part of the British Commonwealth. It symbolizes Canada’s journey towards full autonomy and reflects the country’s evolution into a culturally diverse and politically independent nation.
