Aviva v Cahill: Modified Corvette Insurance Breach Denied Coverage

• The Ontario Superior Court ruled that an insured's estate was not entitled to coverage after the policyholder failed to disclose performance modifications to his 2011 Chevrolet Corvette.
• The modifications, made in March 2018, rendered the vehicle faster and were deemed a material change in risk that should have been reported to Aviva Insurance Company of Canada.
• The non-disclosure constituted a breach of the insurance contract, allowing Aviva to deny its obligation to defend or indemnify the estate in civil actions stemming from a fatal August 2018 collision.
• The accident resulted in three deaths and two serious injuries, leading to criminal convictions for dangerous driving and multiple civil lawsuits.
• The court found that Aviva would not have insured the modified vehicle, reinforcing the critical duty of policyholders to disclose any alterations affecting risk.

Failure to inform an insurer about a material change in risk, such as performance-enhancing alterations, can lead to a breach of the insurance contract.

A tragic motor vehicle collision in August 2018 resulted in three fatalities and serious injuries to two other individuals. The incident involved a 2011 Chevrolet Corvette, driven by the respondent, which collided with another vehicle making a left turn after the Corvette entered an intersection at high speed. The driver of the other vehicle, her son, and another passenger died, while her daughter sustained severe non-fatal injuries. A passenger in the Corvette also suffered serious injuries.

Prior to this devastating event, the respondent had secured an automobile insurance policy for his Corvette with Aviva Insurance Company of Canada in September 2016, renewing it in September 2017, which provided $2 million in liability coverage. However, in March 2018, the respondent undertook performance modifications to the vehicle. Following a trial in October 2021, the respondent was convicted on three counts of dangerous driving causing death and two counts of dangerous driving causing bodily injury. These convictions led to four separate civil actions seeking damages, naming the respondent and the other driver as defendants in most cases, with one action pursuing claims under Ontario's Family Law Act, 1990, related to the deceased driver. After the respondent's death, the court permitted these proceedings to continue against his estate.

Aviva subsequently added itself as a statutory third party to these civil actions, as permitted under section 258(14) of Ontario's Insurance Act, 1990. The insurer then advanced an "off-coverage" position, asserting it had no obligation to defend or indemnify the insured's estate. In May 2024, Aviva initiated a coverage application, arguing that it would not have insured the Corvette had it been aware of a material change in risk. The insurer sought declarations from the court regarding its rights and obligations under the policy.

Aviva's argument hinged on the insured's duty to disclose significant alterations to his vehicle. Specifically, the Ontario Automobile Policy (OAP 1), section 1.4.1, mandates that an insured must notify the insurer of any substantial change that could elevate the risk of an incident or influence the insurer's decision to provide coverage at the existing rate. Furthermore, Statutory Condition 1 of O Reg 777/93, which governs automobile insurance in Ontario, requires policyholders to inform their insurer about any known material change in risk. The core issue was whether the performance modifications constituted such a material change that should have been disclosed.

The Ontario Superior Court ultimately sided with Aviva, granting the insurer's application. Justice M.J. Lucille Shaw determined that the respondent's failure to disclose the performance modifications constituted a breach of his insurance contract. The court relied on expert testimony from two specialists who confirmed that the adjustments made to the Corvette were designed to enhance its speed. The court reasonably inferred that the respondent had invested a significant sum in these modifications with the explicit purpose of making the vehicle faster.

Justice Shaw emphasized that, "In my view, any reasonable insurer would consider that as a significant factor in determining whether it wanted to insure the vehicle at all or in setting a higher premium." The court also considered Aviva's specific decline rule, 7.2.2, concluding that the insurer would not have provided coverage for the Corvette if it had been informed of the alterations. Justice Shaw further elaborated on the increased risk, stating, "The modifications made this a riskier vehicle to insure not only for the speeds it could achieve but also based on the profile of a driver who made those changes and the reasons he did so." Consequently, the Superior Court found that the respondent's non-disclosure allowed Aviva to deny its obligations to defend and indemnify.

This ruling from the Ontario Superior Court underscores the critical importance for vehicle owners to disclose any modifications, particularly those affecting performance, to their automobile insurers. The decision highlights that failure to inform an insurer about a material change in risk, such as performance-enhancing alterations, can lead to a breach of the insurance contract. This breach can have severe consequences, allowing the insurer to deny coverage and indemnification, even in cases involving catastrophic accidents with multiple fatalities and injuries.

For legal professionals, this case serves as a stark reminder of the duty to advise clients thoroughly on their disclosure obligations under automobile insurance policies. Lawyers must stress that any alteration, especially those impacting a vehicle's speed or handling capabilities, could be deemed a material change in risk. Non-disclosure not only jeopardizes the insured's coverage but can also leave them personally liable for substantial damages in the event of an accident, as demonstrated by the continuation of civil actions against the deceased respondent's estate.

Lawyers must advise clients on the critical importance of disclosing *any* vehicle modifications, particularly those affecting performance, to their automobile insurers. Failure to do so, as demonstrated by this Ontario Superior Court decision, can lead to a breach of contract, allowing the insurer to deny coverage and indemnification, even in severe accident cases involving multiple fatalities and injuries.
