The non-compete that
actually holds up.

By Jonathan Kleiman, Barrister & Solicitor · Published June 2026

When clients hear the word "non-compete," they usually arrive with one of two beliefs, and both are half-right. Employers think these clauses are bulletproof. Employees think Ontario banned them and they are worthless. The truth depends almost entirely on a single question: was the non-compete signed by an employee, or by someone selling a business? Because in Ontario, those are two completely different legal worlds.

This article is about the second world — the non-compete a seller gives when they sell their business. It is the version that actually holds up. A covenant a court would strike down in a heartbeat in an employment contract can be solidly enforceable when it is part of a sale, and the much-discussed Ontario ban on employee non-competes does not touch it. If you are buying a business, this is how you protect what you are paying for. If you are selling one, this is what you are signing up to be bound by.

Below I will walk through why the sale-of-business non-compete gets such different treatment, the Supreme Court framework that governs it, how the employee ban carves it out, what "reasonable" actually means, and the one drafting trap that quietly sinks otherwise-good covenants. None of this is legal advice for your specific deal — every transaction is different — but after years of doing buy-and-sell work in Ontario, this is the framework I want both sides to understand before they sign.

Why a sale-of-business non-compete is a different animal

Start with the intuition, because it explains everything that follows. Courts are deeply suspicious of non-competes in employment contracts. The reason is power: an employer hands a take-it-or-leave-it document to someone who needs the job, the two sides are nowhere near equal, and a clause that stops a person from earning a living in their field is a serious thing. So the law reads employment non-competes narrowly, against the employer, and — as we will see — Ontario has gone further and banned most of them outright.

A non-compete on the sale of a business is the opposite situation in almost every respect. Two businesspeople, each with their own lawyer, negotiate a deal at arm's length. The seller is being paid — often substantially — and a real chunk of that price is for goodwill: the customers, the reputation, the momentum the buyer is acquiring. The non-compete is the thing that makes goodwill worth paying for. Without it, the seller could take the cheque, walk across the street, reopen, and pull every customer right back. The buyer would have paid for goodwill and received nothing.

So the law treats the sale-of-business covenant with respect rather than suspicion. It is not a stronger party squeezing a weaker one; it is a bargained-for term protecting an asset that was actually bought and sold. That difference in why the clause exists drives the whole legal framework — and it is why "Ontario banned non-competes" is the wrong headline to apply here.

What "goodwill" really means in this context

Goodwill sounds abstract, but in a sale it is the most concrete thing in the room. When you buy a business, the physical assets — equipment, inventory, the lease — are often the smaller part of the price. The larger part is the going concern: a customer list that buys again, a name people trust, referral relationships, a reputation built over years. That is goodwill, and it only transfers if the seller agrees not to compete it away. The non-compete is, in a real sense, the mechanism that delivers the goodwill you paid for.

The legal framework: presumed valid unless unreasonable

The governing authority is the Supreme Court of Canada's decision in Payette v. Guay Inc. (2013). The Court drew the crucial line: the rules for a restrictive covenant depend on whether the covenant is tied to a sale of a business or to a contract of employment. That single distinction changes the standard the covenant is judged by.

In the sale-of-business (commercial) context, a restrictive covenant is presumed lawful — valid — unless the party challenging it shows that it is unreasonable. That is a far gentler standard than the suspicion applied to employment covenants, where the onus effectively runs the other way. The Court's reasoning tracked the intuition above: the parties to a sale are competently advised, bargain with roughly equal power, and the covenant protects the goodwill the buyer paid for. On that footing, courts will set aside a commercial covenant only in exceptional cases.

The practical takeaway is significant. In an employment dispute, the starting assumption tilts against the clause. On a business sale, the starting assumption tilts toward it. The seller who wants out from under the covenant carries the burden of proving it unreasonable — and "I'd rather not be bound" is not unreasonableness. That is what people mean when they say sale-of-business non-competes "hold up": the law gives them the benefit of the doubt that employment clauses never get.

The Ontario ban — and its sale-of-business exception

Now to the part that confuses almost everyone. Effective October 25, 2021, Ontario amended the Employment Standards Act to prohibit most employee non-competes. An employment agreement that contains a prohibited non-compete is void. This is the source of the widespread belief that "non-competes are banned in Ontario." For ordinary employees, that is broadly true — and you can read more about that side of it in my guide on non-compete enforceability in Ontario.

But the statute contains an express sale-of-business exception. The ban does not apply where, on a sale of a business, the seller becomes an employee of the buyer immediately after the sale. In plain terms: the legislature carved the business-sale context out of the prohibition. A non-compete given by a seller in that situation is permitted — it is not caught by the employee ban at all.

This matters because it is the most common way I see people get the law wrong. A seller signs a non-compete as part of the sale, often staying on to help with the transition, then later reads a headline about the ban and assumes the clause is void. It is not. The exception was written precisely for this scenario — a seller who becomes an employee of the buyer right after closing — and it keeps sale-of-business covenants squarely outside the prohibition. The covenant still has to be reasonable, but the ban is not the seller's escape hatch.

What "reasonable" actually means

Presumed valid does not mean unlimited. Even on a sale, the covenant has to be reasonable, and reasonableness is assessed along three familiar axes — measured, in every case, against the goodwill the buyer actually acquired.

• Scope of activity. What the seller is barred from doing should track the business that was sold. A covenant that stops the seller from running the same kind of business is reasonable; one that sweeps in unrelated lines the seller never operated reaches beyond the goodwill purchased.
• Duration. How long the restriction lasts has to be justified by what the buyer reasonably needs to retain the customers and reputation it paid for. There is no magic number — the period has to fit the deal, not a template.
• Geographic area. The territory should match where the business actually operated and built its goodwill. A provincial or national business may support a broad area; a local one cannot claim the whole country.

The unifying principle is that "reasonable" means tied to protecting the goodwill actually acquired — not broader. Every term should be answerable to the same question: does this protect what the buyer bought? A covenant that can answer yes on activity, duration, and geography is on solid ground. One that overreaches on any axis invites the challenge that it is unreasonable — and on a sale, unreasonableness is the only real way to defeat the presumption of validity.

Reasonable for whom — the buyer or the seller?

Reasonableness is judged objectively, by reference to the goodwill at stake, not by which side would prefer a wider or narrower clause. A buyer who tries to write the broadest possible covenant is not making the deal safer — they may be making it more vulnerable, because overreach is exactly what a court tests for. A covenant scoped tightly to the goodwill is, paradoxically, the stronger one. The interests of both sides converge on the same drafting discipline: tie it to the business sold.

Why courts rarely rewrite an overbroad covenant — so draft it right

Here is the trap, and it is the most important practical point in this whole article. Ontario courts rarely "blue-pencil" — read down, narrow, or rewrite — an overbroad commercial covenant. People assume that if a clause is a little too wide, a judge will simply trim it to a reasonable size and enforce the rest. That is not how it usually works. If a covenant is drafted too broadly, the realistic outcome is that the whole covenant fails.

Think about what that means for the buyer. You pay for goodwill, you put a non-compete in the agreement to protect it, the seller competes anyway, you go to enforce — and because someone drafted the territory or the duration too aggressively, the entire clause is unenforceable. You do not get the reasonable version you should have asked for in the first place. You get nothing. The presumption of validity is generous, but it does not rescue a clause that overreaches.

The lesson writes itself: draft it carefully and reasonably from the start. The temptation, especially for a buyer, is to grab as much as possible — every line of business, the longest period, the widest map. That instinct is backwards. The covenant most likely to actually protect you is the one scoped honestly to the goodwill you acquired, because that is the one a court will enforce. There is no second chance to make it reasonable once you are in litigation.

The buyer's view vs. the seller's view

The same covenant looks very different from each side of the table, and a good deal accounts for both.

From the buyer's side, the non-compete is not a nicety — it is part of what you are purchasing. The price reflects goodwill, and goodwill is worthless if the seller can immediately compete it away. So you want a covenant with real teeth: scoped to the business, lasting long enough to lock in the customers and reputation, covering the territory the business served. But "real teeth" does not mean "as broad as possible." The buyer's genuine interest is in a covenant that survives a challenge, and that means resisting the urge to overreach.

From the seller's side, the covenant is a real constraint on what you can do next, and you should understand it fully before you sign. You are getting paid for the goodwill, and part of that bargain is genuinely stepping back from competing for it. What you want to avoid is agreeing to something broader than the deal justifies — a clause that keeps you out of work you never sold, for longer or wider than the goodwill warrants. A seller who is competently advised can push the covenant back to what is actually fair, which, not coincidentally, is also what is most enforceable.

The two perspectives meet in the same place. A covenant tightly tied to the goodwill protects the buyer and treats the seller fairly — and it is the version the law is most willing to enforce. The drafting discipline that serves enforceability serves both parties.

Non-solicitation and confidentiality: the companions

A full non-compete is the broadest restrictive covenant, but it is rarely the only one in a well-drafted sale agreement. Two narrower cousins do related work, and they matter both as companions and, in some deals, as alternatives.

Non-solicitation stops the seller from poaching the customers or employees of the business that was sold, without barring them from working in the field at all. Because it is less restrictive than a full non-compete — it protects relationships rather than fencing the seller out of an entire industry — it is often easier to defend, and in some transactions a non-solicit alone does the job. I dig into the distinction in my guide on non-compete vs. non-solicitation clauses in Ontario.

Confidentiality covers a third thing entirely: the business's information — its customer data, pricing, methods, supplier terms. A confidentiality covenant keeps the seller from taking the know-how of the business and using it elsewhere, which is a real risk even where a non-compete or non-solicit is in place.

Many sale agreements use all three together — non-compete, non-solicitation, and confidentiality — each tuned to a different slice of what the buyer is protecting. Where a full non-compete would be hard to justify, a tightly drawn non-solicit and a confidentiality clause can carry much of the load. The right combination depends on the business and the deal, which is exactly the kind of judgment worth getting right at the drafting stage.

Common mistakes I see

Over the years, the same handful of errors come up on both sides of these deals — and each one is avoidable.

Assuming the ban applies to a sale. A seller signs the covenant, later hears Ontario banned non-competes, and assumes they are free. The sale-of-business exception means they almost certainly are not. Relying on the ban as an escape hatch in a sale context is the single most common misunderstanding I correct.

Drafting it as broad as possible. A buyer, wanting maximum protection, asks for every line of business, the longest term, the widest territory. Because courts rarely narrow an overbroad covenant, this aggressive instinct can produce a clause that protects nothing at all when it is challenged. Broad is not safe; tied-to-the-goodwill is safe.

Borrowing an employment template. A sale covenant and an employment covenant are governed by different rules. Lifting language from an employment contract — or, worse, from a banned employee non-compete — misses the point that the sale context has its own standard and its own exception. The document should be built for a sale.

Ignoring the narrower tools. Treating the full non-compete as the only option, when a non-solicitation clause and confidentiality covenant might protect the buyer's real interests more defensibly, leaves value on the table. The strongest agreements layer the covenants rather than betting everything on the broadest one.

Not reading what you signed. Sellers in particular sometimes treat the covenant as boilerplate and discover its reach only when they want to start something new. On a sale, the covenant is enforceable — so read it, negotiate it, and understand it before closing, not after.

Where this fits in the bigger deal

The non-compete does not live in isolation. It is one term in a larger transaction, and how the deal is structured shapes how the covenant is drafted. Whether you are doing an asset purchase or a share purchase affects how the goodwill and the covenants are documented, and the covenant should be built into the agreement of purchase and sale alongside everything else you are negotiating. My checklist for buying a business in Ontario walks through where the restrictive covenants sit in the overall process.

On the sell side, the non-compete is often a key piece of exit planning — both because it affects what you can do after the sale and because a clean, enforceable covenant can make your business more attractive and more valuable to a buyer. A seller who understands going in that they will be bound can price and plan accordingly. The covenant is not an afterthought; it is part of what makes the goodwill saleable in the first place.

Key takeaways

• A sale-of-business non-compete is presumed valid. Under Payette v. Guay Inc., a covenant tied to a sale of a business is presumed lawful unless shown to be unreasonable — far gentler scrutiny than an employment clause, and courts set them aside only in exceptional cases.
• The Ontario ban does not catch it. The Employment Standards Act bans most employee non-competes (since October 25, 2021), but there is an express exception where, on a sale, the seller becomes an employee of the buyer immediately after — so sale covenants survive the ban.
• It still has to be reasonable. Scope of activity, duration, and geography all have to be tied to protecting the goodwill the buyer actually acquired — not broader.
• Courts rarely rewrite an overbroad covenant. Ontario courts seldom "blue-pencil" a commercial covenant, so an overbroad clause can fail entirely. Draft it carefully and reasonably from the start.
• Use the narrower tools too. Non-solicitation and confidentiality are often safer companions to — or alternatives for — a full non-compete, each protecting a different slice of what the buyer paid for.

Frequently asked questions

Can a non-compete be enforced when I sell my business in Ontario?

Generally yes. A non-compete given by a seller on the sale of a business is treated very differently from one signed by an employee. In the leading case, Payette v. Guay Inc., the Supreme Court of Canada held that a covenant tied to a sale of a business is presumed lawful unless it is shown to be unreasonable — much gentler scrutiny than in employment, because the parties were competently advised with roughly equal bargaining power and the covenant protects the goodwill the buyer paid for. Courts set these aside only in exceptional cases. It still has to be reasonable, so get it reviewed.

How is a sale-of-business non-compete different from an employment one?

They are governed by different rules and judged by different standards. An employment non-compete is viewed with suspicion because of the imbalance between employer and employee, and is read narrowly against the employer. A sale-of-business covenant, by contrast, is presumed valid unless shown to be unreasonable — the parties are sophisticated, advised, and bargaining at arm's length, and the buyer is protecting goodwill it actually paid money for. The practical effect is that a sale covenant a court would strike down as an employment clause can be perfectly enforceable on a sale. Same words, very different legal treatment.

Didn't Ontario ban non-competes?

Ontario banned most employee non-competes as of October 25, 2021 under the Employment Standards Act, and an agreement that breaks that rule is void. But there is an express sale-of-business exception: a non-compete is permitted where, on a sale of a business, the seller becomes an employee of the buyer immediately after the sale. So sale-of-business covenants are not caught by the employee ban. That is one of the most misunderstood points I deal with — people read "non-competes are banned" and assume it applies to a business sale, when the statute carves the sale context out.

What makes a sale-of-business non-compete reasonable?

Reasonableness is judged on three axes: the scope of activity it restricts, its duration, and its geographic area — all measured against the goodwill the buyer actually acquired. A covenant that tracks the business sold, lasts a sensible period, and covers the territory the business actually served tends to be reasonable. One that sweeps in lines of business the seller never ran, lasts far longer than needed, or blankets the whole country when the business was local starts to look unreasonable. The test is protection of the goodwill bought, not maximum restriction. Tie every term back to what was sold.

How long can a sale-of-business non-compete last?

There is no fixed number in the statute or the case law — it depends on what is reasonably needed to protect the goodwill the buyer acquired. The honest answer is that the duration has to be justified by the deal, not pulled from the air. A period long enough for the buyer to retain the customers and reputation it paid for can be reasonable; a period far longer than that, with no connection to protecting goodwill, risks being struck down. Because Ontario courts rarely rewrite an overbroad covenant, an unjustified term can sink the whole clause. Have the duration set by reference to your specific transaction.

Can a sale-of-business non-compete cover all of Ontario or all of Canada?

It can — but only if the geography is genuinely tied to where the business operated and built goodwill. A business that sold across the province or the country may reasonably support a broad territory; a neighbourhood business cannot. The danger is overreach: claiming all of Canada for a business that served one city is exactly the kind of unreasonable scope a court will scrutinize. And because Ontario courts seldom blue-pencil an overbroad covenant down to a reasonable size, getting the geography wrong can void the entire restriction rather than just trimming it. Match the territory to the real footprint of the business sold.

Will a court fix an overbroad sale-of-business non-compete?

Usually not. Ontario courts rarely "blue-pencil" — read down or rewrite — an overbroad commercial covenant. If a covenant is drafted too broadly, the realistic outcome is that the whole covenant fails, not that the court quietly narrows it to something enforceable. That is the single most important drafting lesson here: you do not get a second chance to make it reasonable in litigation. The presumption of validity on a sale is generous, but it does not rescue a clause that overreaches. Draft it carefully and reasonably from the start, scoped to the goodwill actually acquired.

What's the difference between a non-compete and a non-solicit here?

A non-compete stops the seller from carrying on a competing business at all within the defined scope, duration, and territory. A non-solicitation clause is narrower: it stops the seller from poaching the customers or employees of the business that was sold, without barring them from working in the field generally. Because it is less restrictive, a non-solicit is often easier to defend and is a useful companion to — or, in some deals, a substitute for — a full non-compete. Confidentiality covenants do a third job: protecting the business's information. Many sale agreements use all three together.

I'm buying a business — how do I protect what I'm paying for?

Much of what you buy in a business is goodwill — its customers, reputation, and momentum — and that evaporates if the seller can reopen across the street and take it back. So you protect it with well-drafted restrictive covenants in the purchase agreement: a non-compete scoped to the goodwill you acquired, a non-solicitation clause covering customers and staff, and confidentiality over the business's information. The key is reasonableness tied to what you bought — overreaching can void the protection entirely because courts rarely rewrite an overbroad covenant. Have a lawyer draft these as part of the deal, not as an afterthought.

Do I need a lawyer to draft or review a sale-of-business non-compete?

I would strongly recommend it on either side of the deal. The law here is favourable but unforgiving in one specific way: a covenant scoped correctly to the goodwill is presumed valid, but one that overreaches can fail entirely because Ontario courts rarely narrow it for you. Getting the scope of activity, duration, and territory right — and tying them to the actual transaction — is exactly the kind of judgment a lawyer brings. Whether you are the buyer wanting real protection or the seller wanting to know what you are bound to, have the covenant drafted or reviewed before you sign. This article is general information, not legal advice for your situation.

Final thoughts

The non-compete on a business sale is one of the few in Ontario that does what people expect a non-compete to do: it holds. The law presumes it valid, the much-publicized employee ban carves it out, and a court will enforce it — provided it was drafted reasonably, scoped to the goodwill the buyer actually paid for. That is a genuinely powerful tool for a buyer and a real obligation for a seller, and both sides are better off understanding it clearly before they sign.

The catch is the one I keep returning to: the law's generosity does not rescue an overbroad clause. Because Ontario courts rarely narrow a covenant that reaches too far, the difference between a covenant that protects a buyer and one that protects nothing often comes down to careful drafting — activity, duration, and geography each tied honestly to what was sold. Get that right and the covenant is dependable. Get it wrong and the presumption of validity will not save it. For employment non-competes, which are a different question entirely, see my separate guide on non-compete clauses for small businesses.

If you are buying a business, a lawyer who handles acquisitions can make sure the covenant actually protects what you are paying for. If you are selling, a lawyer on the sell side can make sure you know exactly what you are bound to. Either way, an non-compete agreement lawyer should draft or review the covenant before it is signed.
