Are limitation of liability clauses in contracts enforceable in Ontario?

Limitation of liability clauses — provisions that cap the amount one party can recover from the other — are generally enforceable in Ontario between sophisticated commercial parties. Courts respect freedom of contract and will usually uphold an agreed-upon cap, even if the damages actually suffered exceed it.

There are important exceptions. A limitation clause will not protect a party from liability for fraud, intentional misconduct, or in some cases gross negligence. Courts may also refuse to enforce a cap that is unconscionable or buried in fine print where the other party had no meaningful opportunity to negotiate it. In consumer contracts, additional protections under Ontario's Consumer Protection Act can override certain limitations.

The practical drafting advice: the cap should be tied to something commercially meaningful — for example, the total fees paid under the contract in the prior twelve months. Caps set at zero or at a nominal amount that bear no relationship to the contract's value are more vulnerable to challenge. If your business model depends on limiting your financial exposure, having a lawyer review your standard terms ensures the cap is structured to hold up.
