Victoria Day commemorates the May 24, 1819, birthday of Britain's Queen Victoria (who since has had a whole era named for her--the Victorian era). The British have always celebrated the birthday of the ruling monarch. After Queen Victoria's death in 1901, the people of Canada continued to mark her birthday to show loyalty to the British Empire. In the early 1890s, this day was known as Empire's Day. In 1947, the name was changed to Commonwealth Day. Today it is again known as Victoria Day, and it is a legal holiday in all Canadian provinces except Quebec.
