Very fun attraction in Montreal.
It was a cold day, so I had my jacket and a thermal shirt on. Big mistake. As soon as I hit the rain forest area my internal thermometer was done. I was instantly sweating. Taking off my jacket helped, but wow it was nuts. The Maple forest was better, but I wish they let you feel the cold of the Sub-arctic region.
The animals were wonderful. It was great seeing them in a representation of their natural habitat. My favorite happened to be the Canadian Lynx. The penguins were very too.
Get there you will love it.
