I like how its lushly planted indoors. Certainly a step up from Toronto's.
Speaking of bears, I have a few ideas for when the pandas leave (where are they going after that, anyway?):
1. Modify the exhibit for sun bears, or sloth bears as mentioned above.
2. Turn the entirety of the building into an aviary for various asian birds.
When all of the giant pandas are gone from Calgary Zoo by 2023, there are already plans to turn the building into a home for orang-utans.
