Canada Day (French: Fête du Canada) is the national day of Canada, a federal statutory holiday celebrating the anniversary of the July 1, 1867, enactment of the British North America Act, 1867 (today called the Constitution Act, 1867, in Canada), which united three British colonies into a single country, called Canada, within the British Empire.^[1][2][3] Originally called Dominion Day (French: Le Jour de la Confédération), the name was changed in 1982, the year the Canada Act was passed. Canada Day observances take place throughout Canada as well as internationally.

Frequently referred to as "Canada's birthday", particularly in the popular press,^[4][5][6] the occasion marks the joining of the British North American colonies of Nova Scotia, New Brunswick, and the Province of Canada into a federation of four provinces (the Province of Canada being divided, in the process, into Ontario and Quebec) on July 1, 1867. Canada became a kingdom in its own right on that date,^{[n 1][8][9][10][11]} but the British Parliament kept limited rights of political control over the new country that were shed by stages over the years until the last vestiges were surrendered in 1982 when the Constitution Act patriated the Canadian constitution.^{[n 2]}
