July 1 is Canada Day, the anniversary of the Constitution Act, 1867 (formerly called the British North America Act), which united New Brunswick, Nova Scotia, and the United Province of Canada) into a single country, Canada. The day was originally called Dominion Day. It was renamed Canada Day after the Parliament of the United Kingdom enacted the Canada Act in 1982, which made Canada completely independent.
