Canada Day used to be known as Dominion Day and celebrates the anniversary of the Canadian Confederation which happened on 1st July 1867 with the passing of the British North America Act 1867. This took the three separate colonies of the United Canadas, Nova Scotia and New Brunswick and united into a single dominion within the British Empire called Canada. It was renamed in 1982, the same year that the Canadian constitution was patriated by the Canada Act 1982, which severed the vestiges of legal dependence on the Parliament of the United Kingdom.
Celebrations include fireworks, parades, carnivals, barbecues, air and maritime shows.
