I've been to aquariums in Dubai, Boston, Sydney and others around the world and I have to say I was underwhelmed and dissapointed overall. It just doesn't have the " wow" factor that I expected. If you don't have a chance to visit one of the world's top aquariums ( Boston, Dubai, Monterey Ca etc..) then Toronto is a must see. But if you have been to a top aquarium then no need to visit Toronto Ripley's.
