When you designate Remembrance Day as a legal holiday according to the Holidays Act, you put it on the same status as Canada Day and Victoria Day. I think it follows that it would be treated as a statutory holiday, much as these two days already are. If you treat it the same way, the intent would be that it would become a statutory holiday, and I would hate to see having to designate Remembrance Day as a legal holiday as the means to increase the visibility or importance of the day. I don't think a designation is going to change that.
