Insurance policies impose obligations on insureds as well as insurers. Notice requirements and duties to cooperate can become central when a claim arrives late or the insurer says the insured did not provide what the policy required.
Monteith & Sutherland Limited v. Novex Insurance Company, 2026 ONCA 384, involved both issues.
The parties proceeded on an agreed factual basis. The application judge found that the insured had not substantially breached its duty to cooperate. The judge also interpreted a curative provision as permitting notice in the next policy period where the insurer had not suffered prejudice.
Novex appealed. The Court of Appeal dismissed the appeal.
The Court found no error in the application judge proceeding on the agreed facts. It also upheld the conclusion that the insured’s conduct did not amount to a substantial breach of the cooperation obligation.
The notice issue turned on the policy’s own curative wording. The Court accepted the interpretation that allowed notice to be given in the following policy period in the absence of prejudice to the insurer.
The case is a useful reminder that notice disputes are not resolved by looking only at whether a deadline was missed. The precise policy wording matters. So does the seriousness of the insured’s conduct and, where the wording makes it relevant, whether the insurer was actually prejudiced.
That distinction matters for both sides of a claim. Insureds should not assume that late notice is harmless. Insurers should not assume that every departure from a policy obligation automatically ends coverage. The contract may contain language that preserves coverage in circumstances where the breach can be cured.
The Court of Appeal dismissed the insurer’s appeal and left the coverage ruling in place.
