Operated by Alberta’s oldest charity, Calgary Zoological Society, Calgary Zoo is the second largest zoo in Canada. The zoo which had its origins in early 1900s, suffered extensive flooding during June 2013 Calgary floods. The zoo was closed during this period and reopened in November 2013.
Calgary Zoo is also a leading Canadian Centre for conservation and is home to Centre for Conservation Research with many endangered animals in its care.
