Ontario's Non-Compete Ban vs. the Rest of Canada

Ontario is the only Canadian province that has banned non-compete agreements by statute. Everywhere else in Canada, a non-compete clause lives or dies under the common law's demanding "reasonableness" test — and Quebec applies its own distinct civil-law framework on top of that. The result is a patchwork that catches many employees and employers by surprise: a clause that would be automatically void in Toronto can still be argued over, and sometimes enforced, in Calgary or Halifax. A federal bill introduced in 2026 could extend Ontario's approach to federally regulated workers, but as of today it remains a proposal, not law.

Ontario's Statutory Ban

Ontario added Part XV.1 to the Employment Standards Act, 2000 ("ESA") through the Working for Workers Act, 2021, and the government confirms it "was deemed to have come into force on October 25, 2021." Section 67.1 defines a non-compete agreement broadly, as any agreement — or any part of one — that prohibits an employee "from engaging in any business, work, occupation, profession, project or other activity that is in competition with the employer's business after the employment relationship between the employee and the employer ends." Section 67.2 then makes any such agreement void, subject to two exceptions. The definition catches a clause regardless of how it's labelled, and it applies whether or not the restriction is limited by time or geography — Ontario didn't narrow non-competes, it removed them for almost every employee.

The Two Exceptions

Senior Executives

The ban does not apply to an "executive," a term the ESA defines by naming specific C-suite titles: Chief Executive Officer, President, Chief Administrative Officer, Chief Operating Officer, Chief Financial Officer, Chief Information Officer, Chief Legal Officer, Chief Human Resources Officer, Chief Corporate Development Officer, "or any other chief executive position." Employment lawyers have flagged real ambiguity around this list — it's unclear whether it's exhaustive or whether a title like Executive Vice President would qualify — and Ontario courts have not yet fully settled the question. An employer relying on the executive exception for anyone other than a clearly listed C-suite role should not assume the exception applies without legal advice.

Sale of a Business

The ban also does not apply where a business — or part of one — is sold or leased and the seller becomes an employee of the purchaser immediately after the sale, provided the non-compete is contained in the purchase agreement itself. This exception recognizes that a business buyer typically needs the seller's promise not to immediately re-enter the market and compete with the very business just sold, which is a different transaction from an ordinary employer restricting an ordinary employee.

What About Clauses Signed Before October 25, 2021?

A common misconception is that Ontario's ban retroactively voided every existing non-compete. It didn't. The Ontario government's own guidance confirms Part XV.1 "does not prohibit or void non-compete agreements that were entered into prior to October 25, 2021" — those older clauses remain subject to ordinary common-law scrutiny, exactly as they would have been before the ESA amendment. The Ontario Superior Court confirmed this directly in Parekh v. Schecter (2022), enforcing a non-compete tied to a $5.6 million dental practice sale because the agreement predated the statutory cutoff, even though the same clause would likely be void if signed today. Anyone reviewing an older Ontario non-compete needs to check the signature date against October 25, 2021 before assuming either that it's automatically void or automatically enforceable.

Non-Solicitation and Confidentiality Clauses Are Different

Ontario's ban targets non-compete clauses specifically — it does not touch non-solicitation agreements (which stop a departing employee from poaching clients or colleagues without banning them from the field entirely) or confidentiality agreements, provided those clauses are genuinely what they claim to be. A non-solicitation clause drafted so broadly that it functions as a disguised non-compete — for example, one that effectively bars an employee from working in their field at all — risks being recharacterized by a court as a non-compete in substance, and struck down under the same statutory ban despite its label.

Everywhere Else in Canada: The Common-Law Reasonableness Test

No other Canadian province or territory has enacted an Ontario-style statutory ban. Outside Ontario, a non-compete is presumed unenforceable as an unlawful restraint of trade unless the employer can show it is reasonable — a burden the employer carries, not the employee. Courts weigh whether the restriction's duration, geographic scope, and the activities it restricts go no further than necessary to protect a legitimate business interest, such as trade secrets or genuine client relationships, rather than simply suppressing ordinary competition.

The leading authority is the Supreme Court of Canada's decision in Shafron v. KRG Insurance Brokers (Western) Inc., 2009 SCC 6. Shafron had sold his insurance agency to KRG and continued working for the buyer under a covenant restricting him from competing within the "Metropolitan City of Vancouver" for three years after leaving — a phrase with no fixed legal meaning. The Court found the clause ambiguous and therefore unenforceable, and — critically for how Canadian courts approach these clauses generally — declined to simply delete the offending word and enforce what remained.

Why Canadian Courts Rarely Rewrite an Overbroad Clause

This is one of the sharpest contrasts with the United States, where some states' courts will "blue-pencil" an overbroad non-compete — narrowing it to a reasonable scope and enforcing what's left. Canadian courts generally will not. Shafron held that judicial severance is available only in rare cases where the offending part is trivial and not part of the covenant's main purpose, which is a high bar the facts in that case didn't meet. In practice, this means a Canadian employer largely gets one attempt to draft an enforceable clause — an overreaching non-compete is far more likely to be struck down entirely than narrowed and saved, which is exactly why careful, conservative drafting matters more in Canada than it might elsewhere.

Quebec's Distinct Civil-Law Framework

Quebec does not follow the common law at all — non-competes there are governed by the Civil Code of Québec, a written-contract regime. Article 2089 requires that a non-competition stipulation be in writing and expressed in clear terms, and be "limited, as to time, place and type of employment, to what is necessary for the protection of the legitimate interests of the employer." The Civil Code puts the burden of proving the stipulation is valid squarely on the employer. A related provision, article 2095, makes a non-compete unenforceable if the employer terminated the employee without a serious reason, or gave the employee just cause to resign — reflecting a principle that an employer that ended the relationship unfairly cannot also restrict what the employee does next.

Federally Regulated Employees: A Change That May Be Coming

Employees of federally regulated industries — banking, telecommunications, interprovincial transportation, and similar sectors — fall under the Canada Labour Code for matters like hours and termination, but the Code currently has no non-compete-specific provision at all. Their restrictive covenants are governed by the same common-law (or, in Quebec, civil-law) principles that apply to provincially regulated employees in the same province.

That may be about to change. Bill C-31, the Budget 2025 Implementation Act, No. 2, introduced in the House of Commons on May 6, 2026, would add a new division to the Canada Labour Code explicitly modeled on Ontario's ESA framework — prohibiting non-competes for federally regulated employees with the same two categories of exception (business sale, senior executives), and including a one-year transition period before existing clauses would become void. As of this writing, the bill is at second reading in the House of Commons and has not been passed into law. Treat this as a proposal to watch, not a rule currently in force — federally regulated employees today have the same common-law protection (and the same burden on the employer to justify a restriction) as other non-Ontario, non-Quebec employees, unless and until Bill C-31 or similar legislation is actually enacted.

Practical Next Steps

If you're an Ontario employee, start by checking the signature date on your non-compete against October 25, 2021 — that single fact determines whether the statutory ban or the older common-law test applies to your clause. If you're outside Ontario, or federally regulated, assume your non-compete must clear the common-law reasonableness bar, and remember the burden of proving that falls on your employer, not you. Because the exceptions, the Quebec civil-law rules, and the federal bill's progress can all shift the analysis, a short consultation with an employment lawyer licensed in the relevant province is the safest way to know where you actually stand.
