The original Montreal watering hole is definitely the Peel Pub.
You won't find any other place where you can get a glass of beer and a meal for under ten dollars Canadian. Their most popular meals are hamburgers, club sandwiches, fries and wings. They also have reasonably priced stead dinners. Ordering a cheeseburger and fries, it was soon apparently that this was one of the best I've ever had. Another plus is that the pitchers of draft beer are incredibly cheap.
