Most commentary on Canadian non-competes reports a single trend: they are becoming unenforceable. That is half the picture, and acting on the half will cost a business owner money in both directions. The law has split into two tracks running in opposite directions, and the same person can be on both tracks in the same year.
Key Takeaway
Ontario's Working for Workers Act, 2021 added a new part to the Employment Standards Act, 2000, deemed in force October 25, 2021, under which section 67.1 defines non-compete agreements extremely broadly and section 67.2 makes them void, subject to only two exceptions: a narrow list of chief executive roles, and non-competes forming part of a sale or lease of a business where the seller immediately becomes an employee of the purchaser. No other province has a statutory ban; elsewhere non-competes are presumptively unenforceable at common law unless the party relying on them proves reasonableness. Meanwhile the Ontario Court of Appeal in Dr. C. Sims Dentistry Professional Corporation v. Cooke, 2024 ONCA 388 held that non-competition covenants in M&A transactions are generally enforceable between sophisticated commercial parties, applying a presumption of validity. Bill C-31, introduced May 6, 2026, would extend an Ontario-style ban to federally regulated employers with a one-year transition. Critically, courts void unreasonable covenants rather than narrowing them.
The Bifurcation
One legal commentary captures the situation more precisely than any summary of the trend.
The enforceability of non-competition agreements in Ontario has bifurcated into two distinct legal realities. For the vast majority of employment relationships, the restrictive covenant is statutorily void, a casualty of legislative reforms aimed at promoting labour mobility. However, for business owners engaged in commercial transactions, the Ontario Court of Appeal has firmly established that these protections remain robust, provided they are drafted with commercial precision[1].
Consider how that lands on a single person. A Canadian business owner who employs thirty people cannot bind almost any of them to a non-compete; the clause in their standard employment contract is void regardless of how modestly it is drafted. Three years later, that same owner sells the business, and the non-compete they grant the purchaser is not merely enforceable but benefits from a judicial presumption of validity.
The policy logic is coherent, even if the practical effect is disorienting. Employment non-competes restrict labour mobility for people with unequal bargaining power. Commercial non-competes protect goodwill that a buyer has paid for, negotiated between advised parties. Different problems, different answers.
The operational consequence is that a business needs two distinct approaches rather than one policy on restrictive covenants, and the most common error we would expect to see is a single template applied across both, which fails in both directions for opposite reasons.
What Ontario Actually Did
The statutory architecture, because its details drive everything.
Ontario added a new part to the Employment Standards Act, 2000 through the Working for Workers Act, 2021, and the government confirms it was deemed to have come into force on October 25, 2021[2]. Section 67.2 of the ESA prohibits employers from entering into an employment contract or other agreement with an employee that includes a non-compete agreement[1], and if an employer violates this prohibition the non-compete agreement is void[3].
One point of inconsistency in our sources is worth flagging: the new part is identified as Part XV.1 in one source[2] and Part XVI.1 in another[3]. The substantive sections cited, 67.1 and 67.2, are consistent across sources, and a reader needing the precise citation should confirm it against the statute.
The prohibition applies to agreements entered into on or after October 25, 2021, and agreements signed before that date are not automatically retroactively voided[3], a point examined further below.
The Breadth Of The Definition
The definitional provision is where the ban gets its force, and it is drafted to defeat workarounds.
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. The definition catches a clause regardless of how it is labelled, and it applies whether or not the restriction is limited by time or geography. Ontario did not narrow non-competes, it removed them for almost every employee[2].
Three features deserve attention. The phrase "or any part of one" means a non-compete buried inside a broader clause is caught without the whole clause necessarily failing. "Regardless of how it is labelled" defeats renaming: calling it a "protection of business interests" clause changes nothing. And the explicit indifference to time and geographic limits removes the traditional drafting defence entirely, because at common law a narrowly-scoped covenant was the reasonable one. Under the statute a six-month, five-kilometre non-compete is as void as a five-year, nationwide one.
That last point is the one employers most often get wrong. There is no amount of moderation that rescues an employment non-compete in Ontario. The only routes are the two exceptions.
The C-Suite Exception Is Narrower Than You Think
The first exception, and the one most frequently over-claimed.
The ESA exception covers defined senior roles: 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, and any other chief executive position. A senior title alone does not guarantee the exception applies[4].
Another commentary is blunter about the limit: the exception is deliberately narrow, a vice-president, director, or senior manager does not qualify unless they genuinely hold the office of one of the listed C-suite roles, and employers cannot circumvent the ban by simply giving a junior employee an inflated title[5].
For most Canadian small and mid-sized businesses this exception is close to unusable in practice. A company with a sales director, an operations manager and a controller has nobody in the list. The people whose departure would actually damage the business, the top salesperson with the customer relationships, the technical lead, the branch manager, are precisely the people the exception does not reach.
An employer relying on this exception should also consider that the analysis is substantive rather than formal. Appointing a valued manager "Chief Revenue Officer" to capture the exception invites a determination about whether they genuinely hold a chief executive position, and losing that argument leaves a void clause plus evidence of an attempt to circumvent the statute.
The Sale Of Business Exception
The second exception, which matters enormously to anyone selling a business.
Section 67.2(3) provides a statutory exception if two specific conditions are met. First, there must be a sale or lease of a business or part of a business. Second, immediately following the sale, the seller must become an employee of the purchaser[1]. A non-compete may still be enforceable where it forms part of the sale of a business and the seller becomes an employee of the purchaser immediately after the sale, and this exception exists to protect the buyer's investment and goodwill[6].
The "immediately following" condition repays attention, because it creates a structural trap in transaction planning. The exception addresses the situation where a vendor stays on as an employee, which is common in owner-operated sales with a transition period. A vendor who sells and does not become an employee is outside this exception, though as discussed below a non-compete given purely as vendor covenant in the purchase agreement is a commercial covenant rather than an employment one and is analyzed differently.
Separately, the ESA ban does not apply where a non-compete is part of an agreement to purchase or sell a business and the purchaser and seller agree that the seller will not compete with the purchased business after closing; these covenants are standard in most business sale transactions and remain enforceable, subject to common-law reasonableness requirements[5]. The same logic applies between co-owners, and a shareholders agreement will often bind a departing shareholder with a restrictive covenant[5].
That last point is practically valuable and under-used. Non-competes among owners, in a shareholders' or partnership agreement or in a business sale, are not employee non-competes caught by the ESA ban and are often more enforceable, provided they meet the reasonableness standard[7]. A business with several working shareholders has a route to restrictive covenants through the shareholders agreement that is unavailable through employment contracts.
Cooke And The Presumption Of Validity
The decision that established how strong the commercial track has become.
In Dr. C. Sims Dentistry Professional Corporation v. Cooke, 2024 ONCA 388, the Court held that non-competition covenants in M&A transactions are generally enforceable between sophisticated commercial parties with access to legal counsel. Courts apply a presumption of validity and will only interfere in exceptional circumstances, though the clause must still be reasonable in scope, duration, and geography[3].
A presumption of validity is a significant reversal of the default. At common law, restrictive covenants are presumptively unenforceable unless the party relying on them proves they are reasonable[7]. In the commercial M&A context, per Cooke, the presumption runs the other way, and interference is exceptional.
The stated rationale, sophisticated parties with access to counsel, tells a business owner what makes the presumption available. It is grounded in the parties' capacity to negotiate, which suggests the presumption is strongest where both sides were advised, the covenant was actually negotiated rather than imposed, and consideration is clearly identifiable in the transaction.
The practical implication for a vendor is uncomfortable and worth stating: the covenant you grant a purchaser is likely to be enforced. It is not boilerplate to be signed at closing without analysis. Its scope, duration and geography determine what you may lawfully do for years afterward, and if you intend to remain active in your industry in any capacity, that is a term to negotiate rather than accept.
Courts Void, They Do Not Rewrite
The most consequential drafting principle in this entire area, and the one that inverts intuition about over-drafting.
Common grounds for voidness include geographic scope exceeding the actual business footprint, duration disproportionate to the interest being protected, ambiguous definition of restricted activities, lack of consideration, and, for post-October 2021 employment agreements with non-executives, the ESA ban itself. Courts will not rewrite an unreasonable clause; they void it[3].
The consequence is that over-drafting is not a hedge, it is a risk. A purchaser who demands a ten-year, Canada-wide non-compete from the vendor of a single-location business does not obtain a clause that a court will trim to three years and the relevant city. They obtain a clause that may be struck out entirely, leaving no protection at all.
This makes the drafting calculus genuinely counterintuitive. The strongest covenant is not the broadest one; it is the one most closely matched to the actual interest being protected. Geographic scope tied to the business's real footprint, duration proportionate to how long the goodwill and customer relationships being purchased will realistically persist, and restricted activities defined with enough precision to avoid the ambiguity ground.
For a purchaser, this argues for restraint in the drafting rather than aggression, and for evidence supporting the scope chosen. For a vendor, it argues for identifying overbreadth during negotiation rather than relying on a court to fix it later, since the outcome of that gamble is binary.
Legacy Clauses And The Common Law
What happens to the contracts already in your filing cabinet.
Ontario's ban is not retroactive; non-competes signed before October 25, 2021 are not automatically void, but they may still be challenged under common law reasonableness standards, and many older agreements fail due to overly broad restrictions on duration or geography[6]. A pre-ban clause is not voided by the statute; instead it is assessed under the older common-law test, and that test is no friend of broad non-competes either, because restrictive covenants are presumptively unenforceable unless the party relying on them proves they are reasonable, so a pre-ban clause is not safe simply because it predates the ban, it still has to clear a demanding bar[7].
One source puts the practical position more starkly still, noting that pre-October 2021 agreements were rarely enforceable even at common law[3].
The realistic conclusion for an employer is that a pre-2021 non-compete is an asset of uncertain and probably low value. Relying on one to protect a genuine competitive interest, rather than pursuing the alternatives discussed below, is a strategy resting on a clause that is presumptively unenforceable and that the employer bears the burden of defending.
The Rest Of Canada
The provincial picture, which is uniform in a way that surprises people.
As of 2026, in all provinces other than Ontario, non-competes are not statutorily banned but are presumed unenforceable under common law unless proven reasonable[8]. British Columbia's position is representative: non-competes are not banned by statute but BC courts apply strict reasonableness tests[9]. Other provinces apply strict reasonableness tests that frequently render them unenforceable[9].
So the practical difference between Ontario and the rest of Canada is smaller than the headline suggests. In Ontario an employment non-compete is void as a matter of statute. Elsewhere it is presumptively unenforceable and the employer must prove reasonableness to a demanding standard. Neither is a reliable protection. The Ontario position is more certain, not more hostile in outcome.
On the commercial side the position is consistent nationally: in business sale transactions, non-competes are generally enforceable across all provinces if they are reasonable in scope, duration and geography[8], and non-competes in business sale transactions remain enforceable across Canada[8].
One important jurisdictional note: Quebec operates under civil law rather than common law, and restrictive covenants there are governed by civil-law principles[2] including specific Civil Code provisions this article does not address. A business with Quebec employees should not extrapolate from common-law analysis.
There is also a cross-border warning worth repeating: if you are hiring Canadian employees and planning to use the same restrictive covenant template you use in the US, it will almost certainly fail[9].
Bill C-31 And Federally Regulated Employers
The development that changes the picture for banks, telecoms, airlines, railways, interprovincial trucking and other federally regulated businesses.
Currently, federally regulated employees' 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 and senior executives, and including a one-year transition period before existing clauses would become void[2].
Separately, the federal government proposed a similar ban for federally regulated employers in Budget 2025, with consultations beginning in early 2026[8].
Two features are worth noting. The bill is modelled on Ontario's framework, which means the analysis in this article about definitional breadth and the narrowness of the C-suite exception would likely translate. And unlike Ontario's approach, it reportedly includes a one-year transition before existing clauses become void, which would give federally regulated employers a defined window to restructure their agreements rather than facing immediate voidness.
We have not established the current legislative status of Bill C-31 beyond its May 2026 introduction, and a federally regulated employer should verify where it stands. But the direction is clear enough that any such employer relying on non-competes should be building the alternatives now rather than waiting.
What Still Works
The ban is specific, and it leaves several tools intact.
Non-competes are one category of restrictive covenant, a broader term that also includes non-solicitation clauses and confidentiality agreements[5]. Section 67.1 addresses agreements prohibiting an employee from engaging in competitive activity; a clause prohibiting them from soliciting the employer's customers or employees, or from using confidential information, is a different animal.
The practical toolkit for a Canadian employer therefore includes non-solicitation of customers, non-solicitation of employees, confidentiality and trade secret protection, and intellectual property assignment. Each is subject to its own reasonableness analysis and none is a free pass, but none is caught by the statutory ban on non-competes.
There is also a substantive point behind this. A non-compete prevents a former employee from working; a non-solicit prevents them from taking your customers. In most cases the employer's genuine interest is the second, and the first was a blunt instrument for achieving it. An employer forced to articulate what they actually need to protect frequently discovers that a well-drafted non-solicit and confidentiality regime does the real work.
Note also that the ESA ban applies to employees. The position of independent contractors is different, and one source raises the question directly[6], but classification is itself contested territory and an employer should not treat contractor status as a route around the ban without advice, particularly given the reclassification risk examined elsewhere in this publication.
The Taint Problem
A consequence of leaving a void clause in place that goes beyond its unenforceability.
A void clause carries no legal force. More significantly, the presence of such a void clause can taint the employer's broader contractual strategy, signalling that the employer's agreements are non-compliant with current standards[1].
The reputational and strategic dimension is real. An employment agreement containing a plainly prohibited clause tells an employee's counsel that the document was not reviewed against current law, which invites scrutiny of everything else in it: the termination provision, the overtime treatment, the vacation entitlement. In a dispute about something else entirely, a void non-compete is an opening argument about the employer's general compliance posture.
It also creates a practical problem in transactions. A purchaser conducting diligence on an employment agreement portfolio that contains prohibited clauses learns something about the target's compliance systems, and that observation tends to expand the diligence rather than resolve it.
The instruction is simple: remove them rather than leaving them dormant. There is no upside to a void clause and several downsides.
How This Gets Enforced Against You
The exposure is not limited to losing a case you brought.
Employees, applicants, and former employees can file a claim with the Ministry of Labour if they were asked to sign a prohibited non-compete after October 25, 2021, or if they were penalised for refusing to do so[3].
Read that carefully, because it reverses the usual posture. An employer typically thinks about a non-compete as something they might one day try to enforce, and treats an unenforceable clause as merely useless. But the act of asking someone to sign a prohibited clause is itself the subject of a complaint, as is penalising a candidate or employee who declines.
That means an employer whose standard offer package contains a prohibited non-compete is generating a potential complaint with every hire, independent of whether anyone ever leaves to compete. And an employer who withdraws an offer because a candidate refuses to sign it has done something considerably more exposed than presenting an unenforceable clause.
A Worked Case: One Template, Two Failures
An Ontario business with two locations, twenty-eight employees, and an owner planning to sell within five years. The reconstruction below illustrates the pattern rather than reporting a specific engagement.
The company's employment agreement, drafted in 2018 and used unchanged since, contains a two-year non-compete covering the province. It has been signed by every hire, including those made in 2024 and 2025. Those clauses are void under section 67.2, and every new hire asked to sign one after October 25, 2021 has a potential Ministry of Labour complaint. The owner believes the company is protected against departing salespeople and it is not, because the agreement contains no non-solicitation clause at all, the protection having been assumed to flow from the non-compete.
Three years later the owner sells, staying on for an eighteen-month transition. The purchaser's counsel presents a vendor non-compete: ten years, all of Canada, restricting involvement in any business that "competes with or is similar to" the purchased business. The owner, having absorbed the message that non-competes are unenforceable in Ontario, signs it without negotiation.
That covenant sits on the commercial track, where Cooke supplies a presumption of validity between sophisticated parties. Its scope may be vulnerable, geographic reach exceeding the actual footprint and the "similar to" language arguably ambiguous, but the remedy if a court agrees is voidness, not narrowing, and litigating that is not a plan. In the meantime the owner has agreed a restriction that may prevent them from doing anything in their industry for a decade.
Both failures came from one belief: that there is a single Canadian answer on non-competes.
What To Do
Strip prohibited non-competes out of employment templates now. They are void, they generate complaint exposure with every hire, and they signal non-compliance in any dispute or diligence exercise.
Build the non-solicitation and confidentiality regime instead. Non-solicits, confidentiality, and IP assignment are not caught by the ban and usually address the employer's real interest more precisely than a non-compete did.
Do not rely on the C-suite exception loosely. The list is specific, and a vice-president or senior manager does not qualify. Inflating a title to capture it risks a finding of circumvention on top of a void clause.
Use the shareholders agreement where you have working owners. Covenants among owners are not employee non-competes and are analysed on the commercial track.
Negotiate the vendor covenant when you sell. Cooke's presumption of validity means the covenant you sign at closing will probably bind you. Match its scope to the goodwill actually being purchased and read it as a constraint on your next decade.
Draft narrowly, not broadly. Courts void rather than rewrite, so an overbroad covenant risks delivering nothing. Tie geography to the real footprint and duration to how long the purchased relationships will realistically persist.
If you are federally regulated, start now. Bill C-31 would import the Ontario framework with a one-year transition. The alternatives take longer to build than the transition period allows.
Get Quebec advice separately. Civil-law principles govern there and common-law analysis does not transfer.
The Limits Of This Analysis
Several caveats matter. This article draws on employment law commentary rather than the statutes and judgments directly; the characterization of Dr. C. Sims Dentistry Professional Corporation v. Cooke, 2024 ONCA 388 and of the ESA provisions should be verified against the primary sources. Our sources disagree on whether the relevant ESA part is XV.1 or XVI.1, which we have flagged rather than resolved. We have not established the legislative status of Bill C-31 beyond its introduction on May 6, 2026, and readers should verify whether it has advanced. This article does not address Quebec's civil-law regime, the treatment of independent contractors in any detail, garden leave, the specific reasonableness factors courts weigh in each province, remedies including injunctive relief, or the fiduciary duties that may constrain senior employees independent of any covenant. Several sources cited are law firm publications that market employment law services. Nothing here is legal advice; restrictive covenant drafting and enforcement are jurisdiction-specific and should be handled with qualified Canadian employment and corporate counsel.
