In Ontario, the honest answer surprises most people: non-compete agreements are now banned for most employees. Here is what the law actually says, the two narrow exceptions, what still has to be reasonable, and what to use instead to protect a business.

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.
For employees, non-compete agreements in Ontario are generally unenforceable — in fact, void. 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.
Since October 25, 2021, 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.
The ban is not absolute. Two situations fall outside it:
Outside these two boxes, an employee non-compete entered into on or after October 25, 2021 is void.
The prohibition is not retroactive. A non-compete signed before October 25, 2021 is not automatically 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.
The ESA ban applies to employees. Genuine independent contractors are generally not covered, 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.

Here is the practical pivot. The ban targets non-competes only. It does not touch two other restrictive covenants that protect most of what a business actually worries about:
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.
Clearing the ban is only the first hurdle. 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.
Reasonableness turns on whether the covenant is no broader than necessary to protect a legitimate proprietary interest. Courts look at:
If any one of these is overreaching, the whole clause can fall.
A crucial drafting reality: Ontario courts generally will not rewrite or "read down" an unreasonable restrictive covenant to make it enforceable. 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.
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.
If you are protecting a business, stop relying on the non-compete reflex and build a layered, lawful approach:

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. For most employees it does not — the clause may be void. 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.
The ban was not an accident of drafting — it reflects a policy judgment. 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.
The employment context is only one place restrictive covenants appear. Among owners of a business, the calculus is different and the restrictions are often more enforceable. 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.
If the non-compete is off the table for most employees, what does the work? In practice, a layered set of tools:
A contract lawyer can assemble these into a package that is both lawful and genuinely protective — which a void non-compete never was.
Receiving a lawyer's letter accusing you of breaching a non-compete is alarming — but the first question is always whether the clause is even enforceable. For most employees it is not. Before you panic, change your plans, or fire back, 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.
When a genuinely enforceable covenant is breached, what can the business actually get? Two main remedies. 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.
Be careful with templates and assumptions imported from elsewhere. Non-compete law varies widely by jurisdiction — what is standard or enforceable in another province or in a US state may be void in Ontario, and vice versa. 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
