A fatality inquiry has determined that a tragic tour bus rollover in the Columbia Icefield was caused by a complete braking system failure resulting from neglected mechanical repairs. The incident, which led to the deaths of three passengers and injuries to 14 others, occurred on July 18, 2020.
Judge Vaughn Myers of the Alberta Court of Justice released a report detailing a series of critical oversights that preceded the rollover. The tour bus, an Ice Explorer transporting 24 tourists across the Athabasca Glacier in Jasper National Park, descended a steep embankment and overturned, leading to the fatalities.
The investigation revealed that the Ice Explorer had worn components, insufficient brake power, and lacked routine maintenance, ultimately contributing to the catastrophic failure. Myers emphasized the importance of safety improvements by the tour company, Pursuit, formerly known as Brewster. Several warnings regarding the vehicle’s safety issues were reportedly ignored prior to the tragic crash.
During a fatality inquiry held in October 2025, Myers sought to address policy measures to prevent similar incidents and investigate maintenance lapses. The Ice Explorers, large off-road buses used in the Columbia Icefield since the 1980s, are equipped with specialized brake systems tailored for icy terrains.
The inquiry highlighted that the bus’s descent down a steep slope, known as the Lateral Moraine Road, was a critical moment leading to the rollover. Due to severe mechanical defects, the brakes failed, causing the driver to lose control, resulting in the tragic accident.
Further inspection post-crash revealed that only one of the six wheels had adequate braking power. The investigation also revealed that a driver had reported a major braking issue just days before the incident, but the problem was not addressed or documented properly.
The court also scrutinized the servicing of the bus by Wajax, a company responsible for repairs and maintenance. The inspection conducted by Wajax prior to the crash was deemed inadequate, raising concerns about the inspection process and the maintenance work performed.
Myers emphasized the need for Pursuit to enhance its inspection protocols and maintenance procedures to prevent similar tragedies in the future. Pursuit has since implemented significant safety changes, including improved driver training, seatbelt installations in all Ice Explorers, and updated inspection processes.
While Pursuit did not face criminal charges in connection to the crash, the company pleaded guilty to charges under the Alberta Occupational Health and Safety Act in 2023 and was fined $475,000. Pursuit expressed its commitment to working with authorities to uphold safety standards and expressed condolences to the families affected by the tragic incident at the Columbia Icefield.
