Wonder Mountain's Guardian

Wonder Mountain's Guardian is a 4D, interactive dark ride roller coaster at the Canada's Wonderland amusement park located in Vaughan, Ontario, Canada. It is also the first ride part of Cedar Fair's Amusement Dark collection. Park management first proposed a dark ride located inside Wonder Mountain around 2004. Technology and budget limitations at the time delayed the project's planning and design stages until 2011. The steel track was manufactured by Art Engineering; it is approximately 304.8 metres long and has a maximum height of about 18.3 metres. The ride also has one of the largest drop tracks in the world.

Triotech designed the ride's interactive 3D animations, which are accompanied by other special effects such as wind, adding the fourth dimension. During the park's Halloween Haunt event in October, the animations are replaced with zombie-themed effects.
