Maxi Montréal Masson is a very busy supermarket known for its good prices and crazy sales, making it one of the best around. The space is pretty big with a lot of selection and aisles that are not too narrow. However, it can be messy, with shelves often picked clean and items missing, especially special products and sale items. Restocking is constant. The checkouts are very fast, including self-service options, though they can sometimes get stuck. Bagging your own groceries can be a pain. The cashiers and staff are generally really nice and friendly, though not always. The selection focuses on well-known big brands, with some limitations like dairy-free options. Since renovations, the place has improved.
