A coverage opinion is not a verdict, yet it often determines whether a claim proceeds to litigation and on what terms. Throughout this course, we have examined how to obtain a coverage opinion, when to seek one, and how to evaluate the reasoning within it. In this final lesson, we turn to the pivotal moment when a coverage opinion ceases to be an advisory document and instead becomes the foundation for legal action. This transformation carries profound implications for insurers, policyholders, brokers, and the lawyers who represent them. Understanding how and why a coverage opinion evolves into litigation material is essential for any professional involved in the claims process, risk management, or insurance law practice across Canada.
The legal and regulatory foundation for coverage disputes varies across Canadian jurisdictions, though certain principles remain consistent. Insurance contracts in Canada are creatures of both statute and common law, with Quebec operating under its distinct civil law framework governed by the Civil Code of Quebec. In common law provinces such as British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador, the interpretation of insurance policies follows established principles of contract construction developed through decades of jurisprudence. The duty of good faith, which applies to both insurers and insureds, forms a bedrock principle recognized across all Canadian jurisdictions. When an insurer denies coverage based on a coverage opinion, the policyholder has recourse through the courts, and the coverage opinion itself may become a central exhibit in subsequent litigation.
