It's really small comparing to Jean Talon. However, they do have really good selection of Meat, Charcuterie, and Cheese.
If you are visiting Montreal, don't feel too bad if you didn't get a chance to go to visit this market. Numero uno, it's kinda far from center city and it's small. Plus there is not much vendor that you can eat from or at least at the time I was there.
It is very clean market!
If you are staying Montreal and have an apartment or place where you can cook, this would be the place to go and buy your meats, cheese, veggies, etc.
