It was the sloth bear exhibit when I visited in 2006, and it seems to me that it would make a decent (but not very large) giant panda exhibit for the 2018-2023 arrival of the pair from Toronto Zoo.
This exhibit is now for snow leopards, and there are no emus, wallabies or black swans anywhere in the zoo. At one point there was a small Australian section at Calgary Zoo, complete with a tiny Nocturnal House, but that is all gone these days.
