Commercial Vehicle and Trucking Accidents in Ontario: Multiple Defendants and Higher Stakes

Why Commercial Vehicle Accidents Are Different

Accidents involving transport trucks, delivery vehicles, and commercial fleet vehicles present a substantially more complex legal landscape than standard passenger vehicle collisions. Multiple parties may bear liability — the truck driver, the trucking company, the shipper, the vehicle lessor, and maintenance contractors. Federal and provincial regulations govern commercial vehicle operation. And the stakes are typically higher: commercial vehicle accidents frequently produce catastrophic injuries due to the size and weight differential involved.

Federal Regulations and Their Role

Commercial carriers operating across provincial and international boundaries are subject to federal Motor Transport legislation and National Safety Code standards governing hours of service, vehicle maintenance, cargo securement, and driver qualification. A trucking company that violates these standards and whose vehicle causes an accident as a result may be liable not only in negligence but under the doctrine of negligence per se.

Employer Vicarious Liability

A trucking company is vicariously liable for the negligence of its drivers acting in the course of employment. Beyond vicarious liability, the company may be independently negligent in its hiring, training, supervision, and vehicle maintenance practices. These independent bases for employer liability are particularly important where the driver is characterized as an independent contractor — the true nature of the employment relationship, not its contractual label, determines the liability analysis.
