There is a largish boarded up house on St-Rédempteur going north about one street in from the boulevard des Allumettières
Right on the south side of Allumettières there is a boarded up house (kitty corner to the Ultramar). I think it was a crack house that was raided. St-Rédempteur has quite a few of them.
That Portuguese grocery store on Frontenac, west of Eddy, has been boarded up for a while now too..
How about this place on boul. Fournier? It's been vacant as long as I've lived here :
