The Toronto Zoo in Ontario is consistently the most visited zoo in Canada, attracting approximately 1.3 million guests annually. As the largest zoo in the nation, spanning over 700 acres, it is famous for its diverse animal regions, including the Tundra Trek, the African Rainforest Pavilion, and the Great Barrier Reef exhibit. Close behind is the Calgary Zoo in Alberta, which often records over 1.2 million visitors and is renowned for its world-class panda habitat (historically) and its "Prehistoric Park." The Toronto Zoo's popularity is driven by its massive scale and its status as a major cultural landmark in Canada's largest metropolitan area. In 2026, both zoos have seen a surge in attendance due to new "immersive" nocturnal exhibits and a focus on conservation-led education. While the Granby Zoo in Quebec and the Assiniboine Park Zoo in Winnipeg are also top-tier destinations, the Toronto Zoo remains the "gold standard" for volume, offering a comprehensive global wildlife experience that requires several days to fully explore, making it a "must-visit" for families and wildlife enthusiasts visiting the East.
