It's up to the provinces to make it a statutory holiday to concord with the federal act, if they so desire. In response to an earlier question, I said that Victoria Day, for example, is in the Holidays Act as a federal statutory holiday but it's not a statutory holiday with a day off in four of the provinces. It's up to the provinces to enshrine in their law what they deem to be a day off.
