I'm from Montreal and I heard about that aquarium and as soon as I saw pictures of that hallway with water and fish all around I knew I had to give it a visit. It's a small aquariums with different little buildings with themes. It's quite nice and has a quiet place. If you plan on visiting go around 12pm to make sure you could assist the little shows they have going on. I don't regret a second ! Just make sure you know that it's not that big. My other favorite place was dark rooms with different lighting and there's jellyfish just swimming around.
