Today, Canada celebrates Canada Day.
Unlike Indonesia or USA, Canada Day does not equal Independence Day. Since the time long ago, territories on Canada were part of British colonies. On July 1, 1867, apparently 3 of those colonies - Nova Scotia, New Brunswick, and the Province of Canada (Ontario and Quebec) - merged together and became a federation of 4 provinces.
It's interesting to know that Canadians were not really interested to celebrate this day. July 1 became a statutory holiday only in 1879. Even then, Canadians thought of themselves as "primarily British" and thus did not take part in a Canadian patriotism. That was until World War 2.
Beginning 1958, government started to celebrate Dominion Day. And in October of 1982, the name was changed to Canada Day.
Isn't it interesting? I never knew that!
