On July 1st, 1867, the British North America Act united various provinces in a single Dominion of Canada. However, for the first 100 years the Canadians didn’t celebrate this date: it became more prominent the more independence Canada gained from the United Kingdom. Today it is a grand national holiday with parades, carnivals, and concerts.
