Victoria Day is a federal Canadian public holiday celebrated on the last Monday preceding May 25. Initially in honour of Queen Victoria’s birthday, it has since been celebrated as the official birthday of Canada’s sovereign. It is informally considered to be the beginning of the summer season in Canada.
The holiday has been observed in Canada since at least 1845, originally falling on Victoria’s actual birthday (May 24). The holiday has always been a distinctly Canadian observance and continues to be celebrated across the country.
