Opened in 1981 by the Taft Broadcasting Company and The Great-West Life Assurance Company as the first major theme park in Canada, Canada's Wonderland, located in Vaughan, Ontario, remains the country's largest.

Canada's Wonderland is open daily from May to September, and then only on weekends through early November. The park is divided into six theme amusement areas. The park owns Canada's only vertical circle shape roller coaster.
