When Does an Occupant Trigger an Automobile Insurer’s Duty to Defend?

One recurring coverage issue in Ontario insurance litigation is whether a passenger or other occupant of a vehicle qualifies as an “insured” under section 239(1) of the Insurance Act, thereby engaging an automobile insurer’s duty to defend.

Although the question often arises in the context of motor vehicle litigation, the answer depends less on a person’s status as an occupant than on the nature of the allegations pleaded against them. Ontario courts have consistently emphasized that the duty to defend is determined by comparing the pleadings with the insurance policy, rather than by resolving disputed facts.

The Statutory Framework

Section 239(1) of the Insurance Act provides that every owner’s automobile policy insures not only the named insured but also every person who, with the named insured’s consent, drives or is an occupant of the insured automobile against liability imposed by law arising from the ownership, use, or operation of that automobile.

While this language extends insured status to occupants, coverage is not unlimited. The alleged liability must arise from the ownership, use, or operation of the vehicle before the policy responds.

The Duty to Defend

The duty to defend is broader than the duty to indemnify. As the Supreme Court of Canada explained in Nichols v. American Home Assurance Co., an insurer’s obligation to defend is determined by the allegations contained in the pleadings. If those allegations, if proven, could potentially fall within the policy’s coverage, the insurer is generally required to provide a defence.

Importantly, the court does not determine whether the plaintiff will ultimately succeed. Rather, the question is whether there is a possibility that the claim falls within the scope of the policy.

Occupants as Insureds

Ontario courts have recognized that passengers and other occupants may qualify as insureds under section 239(1). Whether an insurer owes a duty to defend, however, depends on whether the pleaded allegations relate to the use or operation of the automobile.

In Morrow (Litigation Guardian of) v. Symons, the Court applied the framework first articulated in Wilkie v. Economical Mutual Insurance Co. and considered three questions:

1. Were the damages occasioned by the use or operation of a motor vehicle?
2. Are allegations of liability made against an occupant of that vehicle?
3. Is there a possibility that the insurer may ultimately be required to indemnify the occupant?

Where each question is answered affirmatively based on the pleadings, a duty to defend will generally arise.

What Does “Use or Operation” Mean?

The Supreme Court of Canada’s decision in Amos v. Insurance Corporation of British Columbia remains the leading authority on whether injuries arise from the use or operation of a motor vehicle.

The Court established a two-part analysis:

• Purpose Test: Did the accident result from the ordinary and well-known uses to which automobiles are put?
• Causation Test: Is there a sufficient causal relationship between the injuries and the ownership, use, or operation of the vehicle, or is the connection merely incidental or fortuitous?

This framework has been applied in numerous subsequent decisions and demonstrates that the concept of “use or operation” extends beyond simply driving a vehicle.

For example, courts have found that activities such as loading or unloading passengers, transporting property, and other ordinary incidents of vehicle use may satisfy the purpose test. In some cases, even conduct occurring outside the vehicle has been found to bear a sufficient connection to its use or operation.

When the Duty to Defend May Not Arise

Not every claim involving an occupant falls within automobile coverage.

In Hunt v. Peel Mutual Insurance Co., the Court considered claims brought by a child against her father following a motor vehicle collision. Although both were occupants of the vehicle, the allegations against the father related to negligent parenting rather than his conduct in using or operating the automobile.

The Court concluded that while the daughter’s injuries arose from the use of a vehicle, the father’s alleged liability did not. Because the pleaded negligence lacked the necessary connection to the use or operation of the automobile, the automobile insurer was not required to defend the claim.

The decision illustrates that an individual’s status as an occupant does not, by itself, determine whether automobile coverage is engaged.

Overlapping Duties to Defend

An automobile insurer and a homeowner’s insurer may both owe a duty to defend where the pleadings allege distinct acts potentially covered under each policy.

In Dominion of Canada General Insurance Co. v. AXA Insurance Co., allegations extending beyond the use or operation of a vehicle were sufficient to engage the homeowner’s insurer’s duty to defend. Similarly, in Pembridge Insurance Company of Canada v. Chu, the Court of Appeal held that alleged aggressive conduct after the insured exited his vehicle potentially triggered coverage under a homeowner’s policy.

Practical Takeaways

The Ontario jurisprudence demonstrates several recurring principles:

• Occupants of a vehicle may qualify as insureds under section 239(1) of the Insurance Act.
• The duty to defend is broader than the duty to indemnify and is determined by the pleadings rather than the ultimate facts.
• The critical issue is whether the alleged liability arises from the ownership, use, or operation of the automobile.
• Courts interpret coverage provisions broadly at the duty-to-defend stage, but they do not decide disputed factual issues in the underlying action.
• Depending on the allegations, an automobile insurer, a homeowner’s insurer, or both may owe a duty to defend.
