Canada Day (Fête du Canada) is the national day of Canada. A federal statutory holiday, it celebrates the anniversary of the July 1, 1867, enactment of the Constitution Act, which united the three separate colonies of Canada, Nova Scotia, and New Brunswick into a single Dominion within the British Empire called Canada.

Although Canada existed prior to 1867, within both the French and British empires, Canada Day is frequently referred to as “Canada’s birthday”. Learn more: Wikipedia.
