There are currently 65 attractions in Canada's Wonderland, a 330-acre (130 ha) theme park complex located in Vaughan, Ontario, Canada. When Canada's Wonderland first opened in 1981, there were 26 attractions. Since then, at least one attraction has been added every year except 2009 and 2013. Canada's Wonderland's newest attraction is Wonder Mountain's Guardian, a 4D interactive dark ride located inside Wonder Mountain, which was added for the 2014 season. For safety, Canada's Wonderland uses a ride rating system that classifies the attractions based on the intensity of the ride. The ratings vary from 1, for rides that are calm and gentle, to 5, for rides that have high speeds, aggressive forces, and rapid elevation changes. A separate set of ride ratings criteria is used for attractions inside Splash Works, a water park that was constructed in the area surrounding the Mighty Canadian Minebuster in 1992. Four years later, Canada's Wonderland expanded the water park by adding a wave pool, an interactive children's playground, and an enclosed water slide. (Full list...)
