This is not only the biggest market in Montreal, it's the biggest open market in North America with fresh local produce all year long, amazing little eateries and local beers. In summer, before getting fresh berries, eat the best street tacos in town (3 for 5$ with pulled pork)and sit down on the oyster bar for desert. Make sure to check the stores on the side streets as well. You can easily spend half a day here and you should!
