It's not going to change how we celebrate or commemorate Remembrance Day, but what it does is correct an error when the Holidays Act was originally passed that, by not having the word “legal” associated with Remembrance Day compared to Canada Day and Victoria Day, it didn't put them on the same level playing field.
Victoria Day is another good example; not every province recognizes Victoria Day. In Ontario I'd say we take it for granted in terms of it being a day off. In Quebec it's La journée des Patriotes, and some of the other provinces don't have it at all. Those are the decisions those jurisdictions have chosen to make themselves.
