Is A Confidentiality Clause Enforceable in Canada?
Confidentiality clauses are generally enforceable across Canada under both common law and Quebec's Civil Code — this is a clause type where the two systems reach broadly similar practical outcomes despite their different doctrinal foundations, since both protect confidential information through contract and a general obligation of good faith or equity.
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, confidentiality is protected through the contractual clause itself and, independently, the equitable doctrine of breach of confidence for information with the necessary quality of confidence disclosed in circumstances importing an obligation of confidence.
Quebec's Civil Code protects confidential information through its general contractual and extracontractual liability provisions, alongside an express good-faith obligation in the performance of contracts — reaching a broadly similar practical result to the common-law approach, even though the underlying legal basis is codified rather than judge-made.
For most commercial NDAs and confidentiality clauses, this is a genuine example of the common-law/Quebec split mattering less than it does for clauses like non-compete or force majeure — a clearly drafted clause is enforced similarly under either system.
What determines the outcome
- Clarity of the contractual clause's scope, duration, and carve-outs, which matters more than which system governs
- Whether the information would independently qualify for protection under the applicable doctrine even without a clause
- Whether the clause attempts to restrict a legally protected disclosure
Practical guidance
- Draft an express, specific confidentiality clause regardless of whether a common-law province or Quebec governs
- Define scope, duration, and permitted disclosures clearly
- Include a carve-out for legally protected disclosures
