Proof that coverage exists without replacing the policy wording.
A certificate of insurance is a document that summarizes key facts showing that an insurance policy exists, such as the insured name, insurer, coverage type, effective dates, and certain limits.
Landlords, project owners, counterparties, and vendors often ask for proof of insurance before work begins or a contract continues. Readers need to know that the certificate is useful evidence of coverage but not the full contract.
Certificates of insurance are common in commercial relationships, contractor work, leasing, and other situations where one party wants confirmation that another party carries insurance. The certificate usually identifies:
In Canada, the certificate is often requested by a project owner, landlord, customer, lender, municipality, or other counterparty that wants evidence that required insurance is currently in place.
A contractor sends a certificate of insurance to a building owner before starting work, showing that the contractor currently carries commercial general liability coverage for the stated term.
A certificate of insurance is not the same as the insurance policy. The policy wording controls the actual rights, limits, exclusions, and obligations.
It is also different from a renewal document. A renewal package changes or continues the policy. A certificate only summarizes the existence of coverage at a point in time.
It is also different from a binder. A binder is about temporary confirmation that coverage is in force before the final policy package is issued. A certificate is usually evidence of an existing policy for a third party that wants confirmation.
The biggest mistake is treating a certificate as if it restates the policy completely. It usually does not. A certificate can summarize limits and broad coverage labels, but it rarely reproduces the actual wording that decides disputes.
Another mistake is assuming a certificate creates rights for every party who receives it. In many cases, the recipient still needs to review the actual policy, the additional insured wording, or the relevant endorsement if contractual protection is important.
Readers also sometimes assume a certificate proves that every required endorsement has been attached exactly as promised in the contract between the parties. That is too casual. Where the detail matters, the underlying policy wording still needs to be checked.
Readers should not rely on a certificate as if it fully restates the policy. If a dispute turns on exclusions, conditions, additional insured wording, or endorsement details, the policy itself still controls.
