Victoria Day is always on a Monday, making this holiday a long weekend, commonly referred to as the Victoria Day Weekend, the May Long Weekend, or the May Two-Four (referring to a beverage consumed on this weekend). The weekend is also called the May 24th weekend, although it does not necessarily always fall on May 24th.
The Victoria Day Weekend is the first popular weekend for spring / summer travel. Lots of people open up their cottages, plant gardens, or just get away. Expect crowds at resorts and hotels and busy highways. Fireworks displays are common, especially on Monday night.
Plan ahead as banks, schools, many stores and restaurants are closed on the Monday. Public transportation will run on the holiday schedule.
