Are non-competes
enforceable?

By Jonathan Kleiman, Barrister & Solicitor · Published June 2026

Non-compete clauses used to be standard boilerplate in Ontario employment contracts. That world is gone. Since late 2021, Ontario has prohibited non-compete agreements for most employees outright — which means a clause your employer made you sign may be worth nothing at all. This guide explains exactly when a non-compete is enforceable in Ontario, the two exceptions that survive, the reasonableness test that applies even to those, and the tools businesses use instead. None of this is legal advice for your specific clause — but it will tell you which questions to ask.

Are non-compete agreements enforceable in Ontario?

For employees, non-compete agreements in Ontario are generally unenforceable — in fact, void — because the province banned them, with only two narrow exceptions. The province banned them. There are two narrow exceptions (a business sale and defined executives), and even where an exception applies, the clause still has to pass the common-law test of reasonableness. For most ordinary employees, a non-compete in their contract simply does not bind them.

When did Ontario ban non-compete agreements?

Since October 25, 2021, the Employment Standards Act, 2000 has prohibited employers from entering into non-compete agreements with employees, and any such non-compete is void. As of that date, the Employment Standards Act, 2000 has prohibited employers from entering into non-compete agreements with employees. The Working for Workers Act, 2021 added section 67.2, which states that no employer shall enter into a contract or other agreement with an employee that is, or includes, a non-compete agreement. If an employer does, the non-compete is void.

A "non-compete agreement" is broadly defined: an agreement that prohibits the employee from engaging in any business, work, occupation, profession, project, or other activity that competes with the employer's business after the employment ends. That is a wide net — and it is the default rule now.

What are the exceptions to the non-compete ban?

The ban has just two exceptions: the sale of a business where the seller becomes an employee of the buyer, and defined executives such as CEO, President, COO, and CFO. Two situations fall outside it:

• Sale of a business. Where, as part of selling a business (or part of one), the seller agrees not to compete with the buyer and immediately becomes an employee of the buyer, the prohibition does not apply to that agreement. This is why non-competes remain a normal feature of a business sale — they protect the goodwill the buyer just paid for.
• Executives. The ban does not apply to employees in 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 grand-sounding title is not enough on its own; the role has to genuinely fit.

Outside these two boxes, an employee non-compete entered into on or after October 25, 2021 is void.

Is a non-compete signed before the ban still valid?

A non-compete signed before October 25, 2021 is not automatically voided, because the ban is not retroactive — but it is still assessed under the common-law test, where restrictive covenants are presumptively unenforceable unless reasonable. 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. At common law, 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.

Do non-competes apply to independent contractors?

The ESA ban applies to employees, not to genuine independent contractors, so a reasonable non-compete with a true contractor may still be enforceable. The catch: whether someone is really a contractor or actually an employee is decided by courts on the substance of the relationship — control, integration, financial risk — not on the label in the contract. Calling someone a contractor does not make them one, and getting that classification wrong can sink both the non-compete and other parts of the arrangement. A contract lawyer can pressure-test the relationship before you rely on the clause.

Are non-solicitation and confidentiality agreements still allowed?

Yes — the ban targets non-competes only, so non-solicitation and confidentiality (NDA) clauses remain available and are the main tools businesses use to protect clients, staff, and trade secrets. It does not touch two other restrictive covenants that protect most of what a business actually worries about:

• Non-solicitation — clauses preventing a departing employee from soliciting the employer's clients, customers, or staff for a period of time.
• Confidentiality / non-disclosure — clauses protecting trade secrets, client lists, pricing, and other confidential information. See our NDA and confidentiality page.

For most employers, a well-drafted non-solicitation clause plus a solid confidentiality agreement protects the real assets — relationships and information — without running into the non-compete ban. These are now the main tools. For the fuller picture of how they fit together, see our guide to non-compete and non-solicitation agreements in Ontario.

Does a permitted non-compete still have to be reasonable?

Yes — even a covenant that clears the ban must still be reasonable at common law, and the party trying to enforce it carries the burden of proving that. Whether it is an executive non-compete, a business-sale non-compete, a non-solicitation clause, or a pre-2021 agreement, the restriction still has to be reasonable at common law. Ontario courts start from the position that restrictive covenants are a restraint of trade and presumptively unenforceable — the burden is on the party trying to enforce the clause to show it is reasonable, both between the parties and in the public interest.

How do courts decide if a non-compete is reasonable?

A covenant is reasonable only if it is no broader than necessary to protect a legitimate proprietary interest, judged by its duration, geography, and scope of activity. Courts look at:

• Duration — how long the restriction lasts. Shorter periods (often months to a couple of years) are far more defensible than multi-year bans.
• Geography — the area covered. A restriction tied to where the business actually operates is more reasonable than a province- or country-wide ban.
• Scope of activity — what the person is prevented from doing. A clause targeting genuine competition is more defensible than one that bars an entire profession.
• Legitimate interest — there must be a real proprietary interest to protect (trade connections, confidential information, goodwill), not just a desire to avoid competition.

If any one of these is overreaching, the whole clause can fall.

Will a court fix or narrow an overly broad non-compete?

Usually not — Ontario courts generally will not rewrite or "read down" an unreasonable restrictive covenant, so a clause that is too broad or ambiguous tends to fail entirely. That is the crucial drafting reality. If a clause is too broad, too long, or ambiguous, the usual result is that it fails entirely — the court does not hand the employer a narrower version. Ambiguity is fatal, not fixable. That is why a precisely drafted, modest non-solicitation clause is worth far more than an aggressive, sweeping one that looks tough but collapses the moment it is tested. Get the drafting right with a restrictive covenant lawyer.

How do you enforce a valid non-compete?

You enforce a valid covenant with a demand letter and, if needed, an injunction plus damages in the Superior Court — Small Claims Court cannot grant injunctions. When a genuinely enforceable covenant is breached — say, a business seller who agreed not to compete, or an executive bound by a reasonable clause — enforcement usually means a demand letter followed, if necessary, by an application for an injunction to stop the breach, plus a claim for damages. Because injunctions are an equitable remedy, this generally happens in the Superior Court, not Small Claims Court (which cannot grant injunctions — see our guide on Small Claims vs. Superior Court). Speed matters: courts are more willing to restrain an ongoing breach than to unwind one months later.

What should employers use instead of a non-compete?

Instead of a non-compete, employers should use a tight non-solicitation clause, a robust confidentiality/NDA, a narrow reasonable non-compete only for executives or a business sale, and a shareholders' agreement for owners. Stop relying on the non-compete reflex and build a layered, lawful approach:

• Use a tight non-solicitation clause for clients and staff.
• Use a robust confidentiality / NDA for information and trade secrets.
• For genuine executives or a business sale, use a narrow, reasonable non-compete that fits an exception and would survive the reasonableness test.
• Protect ownership and competition issues among owners through a shareholders' agreement, where different rules can apply.

Does a non-compete in my employment contract bind me?

For most employees a non-compete does not bind you — the clause is likely void — but non-solicitation and confidentiality obligations can still apply, so do not assume you are entirely free. If you have been asked to sign a non-compete, or you are leaving a job with one in your contract, do not assume it binds you. But do not assume the opposite either: non-solicitation and confidentiality obligations can still apply, and the exceptions are real. Before you act on (or ignore) a restrictive covenant, get it reviewed. A short conversation can tell you whether you are free to compete or genuinely constrained — and whether a former employer's threat has any teeth.

Why did Ontario ban non-compete agreements?

Ontario banned employee non-competes because they had spread to ordinary workers with no trade secrets and little bargaining power, chilling job mobility even when the clauses were probably unenforceable. The ban was a policy judgment, not an accident of drafting. Non-compete clauses had drifted far beyond senior, well-paid roles and were routinely imposed on ordinary workers who had no trade secrets and little bargaining power. Even when those clauses were probably unenforceable, their mere existence had a chilling effect: people stayed in jobs, or turned down better ones, because they feared a lawsuit they could not afford to fight. By voiding employee non-competes outright, Ontario removed that in-terrorem effect and shifted employers toward the narrower tools — non-solicitation and confidentiality — that protect a genuine business interest without locking workers out of their own profession. Understanding that purpose helps predict how courts approach the surviving exceptions: narrowly.

Are non-competes between business owners enforceable?

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. The employment context is only one place restrictive covenants appear, and among owners the calculus is different. A shareholders' agreement or partnership agreement can include non-compete and non-solicitation covenants among the owners, and these are not employee non-competes caught by the ESA ban. Likewise, in a business purchase, the buyer almost always needs the seller bound by a non-compete to protect the goodwill being paid for — which is exactly why the statute carves out the sale-of-business exception. If competition between owners (or between a buyer and seller) is the real concern, the covenant belongs in the ownership or sale documents, drafted to the reasonableness standard, rather than in an employment contract.

What alternatives to a non-compete actually protect a business?

With the non-compete off the table for most employees, protection comes from a layered set of tools: non-solicitation, confidentiality and IP assignment, reasonable notice or "garden leave," and good contracts paired with good culture. In practice:

• Non-solicitation of clients and employees — the single most useful clause for most businesses, and not banned.
• Confidentiality and IP assignment — protecting trade secrets, client data, and work product through an NDA and clear ownership terms.
• Reasonable notice and "garden leave" — keeping a departing employee on notice (and away from clients) for a period, where the contract allows.
• Good contracts and good culture — well-drafted agreements paired with retention practices often protect more than any restrictive covenant.

A contract lawyer can assemble these into a package that is both lawful and genuinely protective — which a void non-compete never was.

What should I do if I'm accused of breaching a non-compete?

If you are accused of breaching a non-compete, the first question is whether the clause is even enforceable — for most employees it is not — so get it reviewed before you panic or fire back. Receiving that lawyer's letter is alarming, but do not treat it as the last word. Before you change your plans, get the clause reviewed: is it an employee non-compete caught by the ban (likely void), or does an exception apply? Is it actually a non-solicitation or confidentiality obligation dressed up in the same paragraph (which may bind you)? Is it reasonable? The answers determine whether the threat is real or empty. Equally, do not assume you are free just because "non-competes are banned" — the exceptions and the other covenants are real, and breaching a genuinely enforceable one can lead to an injunction and damages. Treat the letter seriously, but get advice before you treat it as the last word. See our overview of what a breach of contract is for the broader framework.

What are the remedies for breaching a non-compete?

The two main remedies for breaching a genuinely enforceable covenant are an injunction to stop the breach and damages for the loss it caused — but if the covenant is void, as most employee non-competes now are, there is no breach to remedy at all. The first is an injunction — a court order stopping the breaching conduct, which is often the real prize because it preserves the business's customers and people before the damage is done. The second is damages — compensation for the loss the breach caused, such as profits lost when a departing executive took clients in violation of a valid clause. Proving those damages can be difficult, which is part of why a timely injunction matters so much. The flip side: if the covenant is not enforceable (as most employee non-competes now are not), there is no breach to remedy at all — the clause was void from the start, and the threat carries no real consequence.

Do out-of-province or foreign non-competes apply in Ontario?

A non-compete governed by another jurisdiction's law does not automatically escape Ontario's rules where an Ontario employee is involved, because a clause that is standard elsewhere may be void here. Be careful with templates and assumptions imported from elsewhere; non-compete law varies widely by jurisdiction. A contract that says it is governed by another jurisdiction's law, or that was drafted for a different market, does not automatically escape Ontario's rules where an Ontario employee is involved. If your situation crosses borders — an employer based elsewhere, an employee working in Ontario, or a clause copied from a foreign precedent — do not assume the clause means what it says. Get it assessed against Ontario law specifically.

The bottom line for businesses and workers

For businesses: stop reaching for the non-compete reflex for ordinary employees — it is very likely void — and build protection through reasonable non-solicitation and confidentiality terms, reserving non-competes for genuine executives and business sales, drafted narrowly. For workers: do not assume a non-compete in your contract binds you, but do not assume you are entirely free either, because non-solicitation and confidentiality obligations can still apply. In both cases, the gap between what a clause says and what it can actually do is wide — and closing that gap is exactly what a quick review with a contract lawyer is for.

Key takeaways

• For most employees, non-competes are void in Ontario — banned under the Employment Standards Act since October 25, 2021.
• Two exceptions survive — the sale of a business (seller becomes an employee of the buyer) and defined executives.
• Even those must be reasonable at common law in duration, geography, and scope, and courts will not rewrite an overbroad clause to save it.
• Non-solicitation and confidentiality are not banned and do most of the protective work for businesses.
• Independent contractors and pre-2021 agreements are assessed differently — but the reasonableness bar is still demanding.

Whether you are protecting a business or weighing whether a clause binds you, the practical answer almost never matches the aggressive language on the page — which is exactly why a quick, specific review is worth it.

Frequently asked questions

Are non-compete agreements enforceable in Ontario?

Generally not against employees. Since October 25, 2021, the Employment Standards Act, 2000 prohibits employers from entering into non-compete agreements with employees, and a prohibited non-compete is void. There are two exceptions — the sale of a business and certain executives — and even those must be reasonable at common law.

When did Ontario ban non-compete agreements?

On October 25, 2021, when the Working for Workers Act, 2021 added section 67.2 to the Employment Standards Act, 2000. The ban applies to non-compete agreements entered into on or after that date.

What are the exceptions to the non-compete ban?

Two. First, the sale of a business: where, as part of selling a business or part of it, the seller agrees not to compete and immediately becomes an employee of the buyer. Second, executives: the ban does not apply to employees in defined C-suite roles such as CEO, President, COO, and CFO.

Which executives can still be bound by a non-compete?

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.

Is a non-compete signed before October 25, 2021 still valid?

It is not automatically voided by the statute, because the ban is not retroactive. A pre-ban non-compete is still assessed under the common-law reasonableness test, under which restrictive covenants are presumptively unenforceable unless reasonable.

Can my employer make me sign a non-compete?

If you are an employee, your employer generally cannot lawfully require a non-compete — the ESA prohibits it, and the clause would be void. If you are a defined executive, an independent contractor, or selling your business, a reasonable non-compete may still be enforceable.

Do non-competes apply to independent contractors?

The ESA ban applies to employees, not to genuine independent contractors, so a reasonable non-compete with a true contractor may be enforceable. But whether someone is truly a contractor or actually an employee is a legal question courts decide on the substance of the relationship, not the label.

Are non-solicitation and confidentiality agreements still allowed?

Yes. The ban targets non-compete agreements only. Non-solicitation clauses (not poaching clients or staff) and confidentiality / non-disclosure agreements remain available and are the main tools Ontario employers use to protect their business — provided they are reasonable.

What makes a restrictive covenant "reasonable"?

A reasonable covenant is no broader than necessary to protect a legitimate proprietary interest, and is reasonable in its duration, its geographic area, and the scope of activity it restricts. Shorter, narrower, and more specific clauses are far more likely to be enforced than broad ones.

Will a court fix an overly broad non-compete?

Usually not. Ontario courts generally will not rewrite or "read down" an unreasonable restrictive covenant to make it enforceable. If the clause is too broad or ambiguous, it tends to fail entirely — which is why careful drafting matters so much.

How do you enforce a valid non-compete?

Typically by sending a demand letter and, if necessary, seeking an injunction in the Superior Court to stop the breach, plus damages. Small Claims Court cannot grant injunctions, so enforcement of a restrictive covenant generally happens in the Superior Court.

Do I need a lawyer to review a non-compete?

It is worth it. Whether you are an employer drafting one, an employee asked to sign one, or a buyer or seller in a business sale, a lawyer can tell you whether the clause is enforceable, void, or worth challenging before you rely on it.
