The zoo is operated by the Calgary ZoologicalSociety, an independent no-for-profit organization that is Alberta’s oldest registered charity. The AZA, WAZA, and CAZA accredited zoo was among the first in Canada to be accreditated by all three associations. As of 2013, it is home to almost 800 animals, excluding individual fish and insects, and 120 different species.
The Calgary Zoo is the second largest zoo in Canada and in 2012 was the nation's most visited zoo. The animal exhibits are organized by geographic region, including Destination Africa, Canadian Wilds, Penguin Plunge, Dorothy Harvie Botanical Gardens and ENMAX Conservatory, Eurasia and Prehistoric Park. The zoo is open every day except for Christmas Day.
