We bought a package of Niagara Falls online, which included this butterfly pavilion. The location is quite far from the Falls Town, but if you go to Toronto, you have to pass here. The parking lot at the entrance is large but charges 5 yuan. The exhibition hall is actually a warm room, there are a lot of colorful butterflies in it, some will fly to your hands for you to take pictures. It's good to come here in time.
