Waiver of subrogation in Canadian insurance: how recovery rights may be limited by contract or endorsement.
A waiver of subrogation is an agreement or policy arrangement that prevents or limits the insurer from pursuing recovery against a specified party after paying a covered loss.
This term appears frequently in leases, construction contracts, and commercial insurance requirements. It matters because it changes the recovery position that would normally exist after a claim and can affect contract negotiation, insurer consent, and pricing.
Ordinarily, after a covered loss the insurer may exercise subrogation rights against a responsible third party. A waiver of subrogation changes that expectation for a named counterparty or class of counterparties. In Canada, the issue commonly arises between landlords and tenants, owners and contractors, or parties working together on a project where they want to avoid suing each other after a loss.
The waiver may come from the insurance wording itself, from an endorsement added to the policy, or from a contract that requires the insured to obtain insurer approval for the waiver. That last point matters. A business cannot safely assume that promising a waiver in a contract automatically binds the insurer if the policy does not support it.
The term is also often confused with additional insured status. Those are different tools. Additional-insured status extends some coverage to another party. A waiver of subrogation limits the insurer’s ability to recover against that party after a covered loss. The two may appear together, but they do different jobs.
A tenant’s lease requires the tenant to obtain insurance with a waiver of subrogation in favour of the landlord for certain insured property losses. If the tenant’s insurer later pays a covered fire claim, the insurer may be barred from pursuing the landlord for recovery to the extent the valid waiver applies.
A waiver of subrogation is not the same as saying the other party becomes an insured automatically. It is about recovery rights, not full coverage status.
It is also wrong to assume any contract clause using the phrase is effective without checking the policy or endorsement. The insurance arrangement still has to support the promise.
The effect of a waiver depends on the contract wording, the policy wording, the line of business, and the facts of the loss. Readers should treat it as a technical risk-transfer term rather than a casual clause.
