WHITEHORSE, YT — A Yukon judge has found a tire shop, a trucking company, and a trucking company supervisor guilty in connection with the 2011 death of a technician.

In November 2011, Denis Chabot, a tire technician, crawled underneath a Kenworth truck to get his tools. What he didn’t know was that in the meantime, a dispatcher had climbed into the truck without doing a walk-around right under the nose of a supervisor. Moments later, the truck drove over Chabot and killed him, according to the CBC.

Now two companies North 60 Petro and Integra Tire, and the trucking company’s supervisor, face charges under the Occupational Health and Safety Act.

Territorial court Judge John Faulkner says there were not enough safety procedures in place. He says the tire shop didn’t have lock-out procedures to ensure the truck could not be moved and that the trucking company failed to properly train the supervisor and dispatcher who moved the truck.

No date has been set for sentencing.
