In Canada, national celebrations are held on July 1. The day is currently called Canada Day, but it wasn't always called that.

The old name was Dominion Day, and was established by the British North America act. Canada, after all, isn't a Republic or a Kingdom -- it's a Dominion. On October 27, 1982, an act of Pierre Elliott Trudeau's Parliament changed the name to Canada Day. This seemingly innocuous change angered many staunch monarchists, Tories, and the like, who already perceived that Prime Minister as anti-monarchist.

Some older Canadians still refuse to call July 1 Canada Day, instead preferring "Dominion Day". (Similarly, there were people who disavowed the new Canadian Flag in 1965.)
