Fatal Tour Bus Rollover at Columbia Icefield Prompted Safety Overhaul
By Drooid · · How we work
Core Event
On July 19, 2020, a tour bus operated by Brewster (also known as Pursuit) lost control on the road to the Athabasca Glacier at the Columbia Icefield in Jasper National Park. The vehicle rolled about 50 metres down an embankment and came to rest on its roof. Three passengers—Dionne Durocher, 24, of North Battleford, Saskatchewan; Kamleshbai Patel, 58, and Griva Patel, 28, of Edmonton—were killed, and 14 others sustained serious injuries.
Data & Statistics
- Fatalities: 3 persons.
- Serious injuries: 14 persons.
- Bus speed after the hill crest: nearly 50 km/h (the vehicle’s top speed in fourth gear is limited to 14 km/h).
- Road grade where the bus descended: 40 %, exceeding the manufacturer’s maximum specification of 36 %.
- Braking system: air brakes that failed catastrophically.
Official Statements & Responses
Justice Vaughn Myers, a judge of the Alberta Court of Justice, concluded that the rollover resulted from a “catastrophic” brake failure caused by worn components, improper inspection, and unattended concerns about brake performance. He noted that the driver, after reporting insufficient stopping power, attempted to brake but could not rely on engine braking because the bus was in neutral and six-wheel drive was disengaged. Myers recommended that future inspection reports be dated and detail all work performed, and he highlighted the absence of seatbelts as a contributing factor.
Brewster’s internal investigation acknowledged the findings and led the company to install seatbelts on its fleet and revise driver-training protocols.

- “In short the brakes suffered a catastrophic failure because they were worn, improperly inspected and concerns with respect to the brakes functioning were not attended to,” — Justice Vaughn Myers
Background & Context
The Ice Explorer bus had air brakes and no regulatory requirement for seatbelts. The inquiry, held a year after the accident, could not assign legal blame but issued safety recommendations aimed at preventing similar tragedies on high-grade mountain roads.
