Canada's Wonderland is a 330-acre theme park located in Vaughan, Ontario, Canada, a suburb directly north of Toronto, Ontario, Canada. The park is open seasonally from May to October and contains more than 200 attractions. It opened in 1981 and was Canada's first major theme park.The park, when under the ownership of Paramount Parks from 1994 to 2006 was known as Paramount Canada's Wonderland. When sold to Cedar Fair in 2007, the park reverted to its original name. It was designed by Landscape Architects Richard Strong and Associates and structurally engineered by O.T. Baggio and Associates Professional Engineers.
The park has been the most attended seasonal theme park in North America for numerous years in the 2000s. Almost every year in the decade the park's attendance had reached the 3 million mark, which has been slightly higher than the attendance figures in other major destination parks such as Kings Island, Knott's Berry Farm and Cedar Point. The park also holds the record for most roller coasters in a park outside of the United States with a total of 15.
The park has several themed areas. The four original sections are, International Street, Medieval Faire, Grande World Exposition of 1890 (now Action Zone), and the Happyland of Hanna-Barbera (renamed to Hanna-Barbera Land). Later areas include White Water Canyon (1984), Splash Works (1992), and the expanded children's area including Nickelodeon Central (2003), Kidzville (1998), and Zoom Zone (2001).
Today, Canada's Wonderland has over 200 attractions, including over 60 thrill rides. The park is tied for second place for the record of most roller coasters in one park with 15 in total, and North America's greatest variety. The park features eight themed areas on 330 acres of land which includes a 20 acres waterpark called Splash Works.
