Aquaria are great attractions when they are located next to, and showcase, an area's own natural marine, estuarine or freshwater environments and their native creatures. This makes them unique and worthy of visiting, has obvious local ties to the community, and also encourages the protection of these local environments. Who wants to come to Ottawa to see reef fish and sharks... you can do that elsewhere and it would be totally out of place here.

That said, creating a small aquarium in the unloved Canada and the World Pavilion would be a great use of space, but what would it feature? Perch, northern pike, and muskrats have a limited appeal.

Perhaps it's best to leave aquaria to cities with deep pockets and more charismatic local fauna.
