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.
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.
Hours of service and ELD records: Electronic logging device (ELD) records and driver logbooks documenting hours of service in the days before a serious accident are critical evidence that must be preserved through prompt demand letters. ELD data, GPS tracking records, dispatch communications, and maintenance logs are all subject to production obligations and must be demanded before they are overwritten or destroyed.
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.
Ontario’s climate produces road conditions — ice, packed snow, freezing rain, black ice — that contribute to a significant proportion of annual serious accidents. Winter driving accidents present particular analytical complexity: multiple parties may share responsibility — the driver who failed to adjust to conditions, the municipality that failed to maintain the road, and the Ministry of Transportation for highway conditions. Identifying all potential defendants is an early priority.
Ontario’s Highway Traffic Act requires drivers to operate at a speed and in a manner reasonable for road conditions. Driving at the posted speed limit during a winter storm, on unsanded ice, or with inadequate winter tires can constitute negligence even absent a specific HTA infraction. The standard of care for winter driving requires active recognition of dangerous conditions and meaningful adjustment — including speed reduction and increased following distance.
The 10-day notice rule — critical in winter accidents: Where road surface conditions contributed to your accident, written notice to the responsible municipality within 10 days of the accident is required under the Municipal Act. This notice must be given regardless of whether you have yet retained a lawyer. Failing to give it can significantly reduce or eliminate recovery against the municipality.
Ontario’s Minimum Maintenance Standards for Municipal Highways (O. Reg. 239/02) prescribe the minimum maintenance required for roads of different classifications, including snow and ice removal timelines. A municipality that fails to meet these standards faces liability under the Occupiers’ Liability Act and the Municipal Act. Evidence of prior complaints, maintenance work order logs, and salt and sand application records are all discoverable and frequently determinative in winter road claims.
