Montreal Aquarium

Built for the 1967 World's Fair (Expo 67), the two-building site operated for nearly a quarter of a century in La Ronde before shutting down in 1991.

The main aquarium building featured penguin pools, exhibits space and a gift shop.

The already failing aquarium received even more negative publicity, and Montreal lost its right to care for any dolphins in captivity going forward, an international embarrassment for the city.

After its closure in 1991, even further negativity came about for the city and in larger part the province of Quebec, when the media discovered the aquarium, unable to sell its sharks, made a decision to kill them off (in one failed kill attempt, a sledgehammer was used to finish off the shark).

The former dolphin pool building it occupied now belongs to La Ronde, and today remains vacant and closed off from the public.
