Is A Force Majeure Clause Enforceable in Canada?
Common-law Canada treats force majeure as purely contractual, construed strictly against its own wording, with the doctrine of frustration as a narrow fallback where no clause exists — much like the UK. Quebec's Civil Code, by contrast, expressly codifies "superior force" as a recognised ground excusing performance even without a contractual clause.
This page describes the general approach Canada law takes to this clause type — it is informational, not legal advice on any specific contract. Enforceability in a real dispute depends on the exact wording, the specific facts, and current law, all of which can change. Have your actual clause reviewed by a lawyer before relying on it.
How Canada approaches this
In common-law provinces, force majeure exists only to the extent the contract creates it — courts construe the clause's listed events and general wording narrowly, and a contract without one falls back on the high-threshold doctrine of frustration, which discharges the contract only where performance becomes genuinely impossible or radically different.
Quebec's Civil Code takes a materially different approach, expressly defining "superior force" (force majeure) as a codified concept — an unforeseeable and irresistible event beyond a party's control — that can excuse performance as a matter of law, independent of what the contract itself says, similar to the statutory backdrop found in several EU civil codes.
This means a Quebec contract's force majeure clause often operates alongside, and can be interpreted in light of, the underlying codified concept, while a common-law Canadian contract's clause is typically the sole source of any force majeure protection.
What determines the outcome
- Whether a common-law province or Quebec's Civil Code governs the contract
- In common-law provinces, whether the event is expressly captured by the clause's specific wording
- In Quebec, whether the event meets the codified "superior force" standard of unforeseeability and irresistibility
Practical guidance
- Identify whether a common-law province or Quebec governs before assuming any statutory force majeure backdrop exists
- Draft an express, specific clause regardless of governing law, since relying on frustration or the codified concept alone is unpredictable
- For Quebec contracts, note that the clause and the Civil Code concept operate together, not the clause alone
