I put up this topic as there are always some montrealers or tourists looking for restaurant cooked meals (beyond chinatown or hotel chains) during Christmas when most restaurants are closed. I also found it intesting as did not know you can pick up tourtières and other holiday favourites at PDC.
This article starts listing a few opened on 24th and 25th for christmas meals and we can add others to the list
