Yukon Striker

[3] In 2014, the park requested a geotechnical investigation of the area, extracting soil samples to assess building a roller coaster's concrete foundation.

[4] On 19 December 2017, Canada's Wonderland filed an application for a permit to build nine support footers on the water and amend the waterway with a tunnel travelling under the pond within the park.

[5] A permit was required from the Toronto and Region Conservation Authority (TRCA), as parts of the ride, and the pond beneath it, fall within the Don River watershed.

[3][6] The diversionary channel was built under the pond in order to facilitate the creation of the underwater tunnel, as well as prevent silt runoff downstream.

[4] Construction for the diversionary channel, as well as the ride's underwater tunnel, required the temporary removal of two track pieces and a few supports belonging to Vortex, a roller coaster adjacent to Yukon Striker.

[citation needed] In July 2018, following continuous construction during the operating season, the park began teasing a planned announcement scheduled the following month.

[10] On 24 April 2019, seventy-two people who helped raise funds for The Hospital for Sick Children were invited to test-ride Yukon Striker.

After pausing for 5 seconds, riders plunge 75 metres (245 ft) through the middle of Vortex's helix and into an underwater tunnel, reaching a top speed of 130 km/h (81 mph).

The train dives down another steep drop into an airtime hill and then proceeds counterclockwise through a 360-degree helix that ends at the final brake run.

[16] When it opened in May 2019, Yukon Striker set three world records among Dive Coaster models for speed, length, and drop height.

The completed tunnel for Yukon Striker in August 2018. Work on the tunnel was completed in early 2018, allowing for Vortex to stay operational for the 2018 season
