A fatality inquiry has determined that a tour bus rollover in the Columbia Icefield, resulting in the deaths of three passengers and severe injuries to 14 others, was caused by a complete failure of the braking system due to neglected mechanical repairs. The inquiry, conducted by Judge Vaughn Myers of the Alberta Court of Justice, uncovered a series of critical oversights leading up to the tragic incident.
On July 18, 2020, an Ice Explorer vehicle carrying tourists on the Athabasca Glacier in Jasper National Park rolled over after experiencing brake failure, ultimately landing on its roof. The victims, Dionne Durocher, Kamleshbhai Patel, and Griva Patel, tragically lost their lives in the accident.
Judge Myers, in his report, emphasized the need for safety improvements by the tour company, Pursuit (also known as Brewster), highlighting that warnings regarding the vehicle’s safety were disregarded in the days leading up to the rollover. The investigation revealed significant mechanical issues with the Ice Explorer, including worn components, insufficient brake power, and a lack of routine maintenance.
The fatality inquiry, held in October 2025, aimed to address preventive policy measures and unresolved questions regarding the maintenance of the vehicle that were not adequately answered by authorities. Ice Explorers, large off-road buses utilized in the Columbia Icefield since the 1980s, are designed for icy terrains and feature specialized brake systems.
The inquiry uncovered that the driver of the Ice Explorer lost control while descending a steep slope due to the vehicle being in neutral, leading to a rapid acceleration beyond its safe operating speed. Despite attempts to apply brakes, the mechanical defects rendered them ineffective, resulting in the tragic rollover.
Moreover, the investigation revealed that the vehicle had not received proper maintenance despite a driver’s prior report of a major braking issue. The inspection after the crash indicated that only one of the six wheels had functional brakes, highlighting the negligence in addressing critical safety concerns.
The court also raised concerns about the inspection conducted by a servicing company, Wajax, prior to the accident, pointing out discrepancies in the inspection report regarding the brake system’s condition. The lack of seatbelts and the challenging terrain of the route were identified as additional contributing factors to the incident.
In response to the inquiry’s findings, Pursuit has implemented enhanced safety measures, including improved driver training, installation of seatbelts in all vehicles, and revised inspection and maintenance procedures. The company expressed its commitment to working with regulatory authorities to ensure compliance with safety standards and offered condolences to the families affected by the tragic event.
