Is A Non-Compete Clause Enforceable in Canada?
Non-compete enforceability in Canada depends on which legal system governs. Common-law provinces apply a strict reasonableness test that courts have historically enforced narrowly for ordinary employees, while Quebec's Civil Code expressly regulates non-competition clauses, requiring the restriction be limited as to time, place, and type of employment to be valid.
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 Canada, courts apply a reasonableness test broadly similar to the UK's — protecting a legitimate business interest, reasonable in duration and geography — but have historically been notably strict when reviewing post-employment restraints on ordinary employees, more readily striking a clause down than reading it down to something narrower. Restraints tied to the sale of a business are generally viewed more favourably than ordinary employment restraints.
Quebec's Civil Code takes a different, codified approach: it directly addresses non-competition clauses in the employment context and requires the restriction be limited as to time, place, and the type of employment restricted for it to be valid at all — an employer that fails to meet all three limits risks the clause being void outright rather than merely narrowed.
Because the doctrinal basis differs — judge-made reasonableness in common-law provinces versus an express codified test in Quebec — a non-compete drafted for one system cannot be assumed to transfer cleanly to the other; which province's law actually governs is the essential first question.
What determines the outcome
- Whether the employment relationship is governed by a common-law province or by Quebec's Civil Code
- Whether the restraint arises from ordinary employment (more strictly scrutinised) or a business sale (more favourably viewed)
- In Quebec, whether the clause is limited as to time, place, and type of employment — all three are required
- In common-law provinces, standard reasonableness factors — duration, geography, scope, and the employee's actual role
Practical guidance
- Identify whether the employment is governed by a common-law province or Quebec before drafting the restraint
- For Quebec, ensure the clause expressly limits time, place, and type of employment — all three, not just some
- For common-law provinces, expect stricter scrutiny of ordinary employee restraints than of sale-of-business restraints
- Use non-solicitation and confidentiality clauses as a more reliable fallback across both systems
