I wanted to love the Science Center, we are science lovers, but this place was disappointing. In desperate need of some organization and renovation, we wandered through the different floors but left within an hour and a half. Some neat things were kid oriented so families may have a better time with younger children.
The Science Center is on the CityPass and my expectations were much higher after visiting the aquarium and the Royal Ontario Museum. Considering the price of admission and the location in relation to Toronto's city center, I wouldn't visit again.
