A certificate of insurance is one of the most commonly exchanged documents in commercial real estate transactions across Canada, yet it remains one of the most frequently misunderstood. Landlords routinely request these certificates from tenants before granting possession of leased premises, and tenants routinely provide them believing they have satisfied their insurance obligations under the lease. This exchange happens thousands of times each day in commercial buildings from Halifax to Vancouver, and in a significant number of those transactions, one or both parties holds a fundamentally incorrect understanding of what the certificate actually accomplishes. The certificate of insurance is not itself a contract of insurance. It does not create coverage. It does not guarantee coverage will continue. It does not bind the insurance company to honour claims. It is, at its core, nothing more than a snapshot taken at a single moment in time, showing what coverage existed when the certificate was issued. Understanding this distinction is essential for anyone operating a business in leased commercial space or managing commercial properties, because the gap between what parties believe a certificate proves and what it actually proves can translate directly into significant uninsured losses.
The legal foundation for understanding certificates of insurance begins with the nature of insurance contracts themselves. In all Canadian provinces, insurance policies are contracts between the insured party and the insurance company, governed by provincial insurance legislation and the common law of contracts in most provinces, or by the Civil Code of Quebec in that province. The Insurance Act in Ontario, the Insurance Act in British Columbia, the Insurance Act in Alberta, and equivalent statutes in other common law provinces establish the regulatory framework within which these contracts operate, while Quebec's framework flows from the Civil Code of Quebec read alongside the Act respecting insurance, as of the date of authorship. Regardless of which provincial framework applies, the fundamental principle remains consistent across the country: the insurance policy is the contract, and only the policy itself defines the actual coverage, the actual limits, the actual exclusions, and the actual conditions that must be satisfied for a claim to be paid. A certificate of insurance is a document prepared by an insurance broker or agent that summarizes certain information from the underlying policy, but the certificate is not the policy and cannot modify or expand the policy's terms.
