Mighty Canadian Minebuster, Wooden roller coaster in Vaughan, Canada.

Mighty Canadian Minebuster is a wooden roller coaster at Canada's Wonderland in Vaughan, Ontario. Designed by Curtis D. Summers and built in-house, it is a modified out-and-back layout: after the station the train turns left past the storage depot, climbs the lift hill, then runs through two negative-G hills, passes under a Splash Works waterslide, and finishes in a helix inside a tunnel before the brake run.

Mighty Canadian Minebuster opened with Canada's Wonderland on May 23, 1981, as one of five coasters at the park's debut. It was modelled on the Shooting Star at Coney Island in Cincinnati, Ohio, and designed by Curtis D. Summers. It was meant to anchor a Frontier Canada area, an idea abandoned until that section was built for 2019.

The name refers to the mining theme of Frontier Canada, the section Minebuster was meant to anchor before the plan was dropped; that area only opened in 2019. The ride itself is a wooden out-and-back coaster designed by Curtis D. Summers and built in-house, modelled on the Shooting Star at Coney Island, Ohio.

Riders must be at least 1.22 m tall to board. The two trains each seat 30 passengers in five cars, with three rows of two per car. The track runs 1,167 m and reaches a top speed of 90 km/h on the 27 m first drop.

A plaque at the operator's booth credits Philadelphia Toboggan Coasters with building the ride, but the company stopped making coasters in 1979; the trains, however, were supplied by PTC. The construction crew likely included former PTC workers.
