The ride most famously associated with getting stuck upside down at Canada’s Wonderland is Lumberjack. In a high-profile incident in September 2023, the thrill ride—which features two massive swinging axe-shaped pendulums—experienced a mechanical malfunction that left passengers suspended at the apex of a loop for approximately 45 minutes. Maintenance crews eventually managed to bring the ride back to the ground safely, and there were no serious injuries, though the incident went viral globally. In earlier years, other rides like "WindSeeker" and "The Bat" have had mechanical stoppages, but the Lumberjack incident remains the most noted for its "upside-down" duration. Since then, Canada’s Wonderland has implemented even more rigorous daily inspections and failsafe sensors. By 2026, Lumberjack remains a popular attraction, but the park has used the lessons from that malfunction to enhance their emergency evacuation protocols across all high-intensity thrill rides in the park.
