Canada's Wonderland, formerly known as Paramount Canada's Wonderland, is a 330-acre amusement park located in Vaughan, Ontario, a municipality within the Greater Toronto Area. Opened in 1981 by the Taft Broadcasting Company and the Great-West Life Assurance Company, it was the first major theme park in Canada and remains the country's largest. Cedar Fair purchased the park from Paramount Parks in 2006, and they have owned and operated the park since then.
