Tucked just off Place Jacques-Cartier, Mlle Catherine has been quietly serving up some of Old Montreal’s most thoughtful frozen treats since 2016. Everything is made in-house, from the rotating gelato and soft serve flavours to fruit-packed sorbets built on just three ingredients: fruit, water, and sugar. The soft serve always includes a classic vanilla alongside a new weekly option, while their gelatos are made with local Quebec milk and without gluten, eggs, or gelatin—clean, but never boring. You’ll find seasonal specials alongside mainstays, and a counter team that’s clearly proud of what they’re scooping. It’s a refreshing break from the tourist-trap fare that lines the square: no flash, just fresh ingredients, solid technique, and a commitment to accessibility for all diets. Whether you’re walking the waterfront or winding down dinner, Mlle Catherine is a reminder that Old Montreal still has room for something genuine.
