Non-compete agreements in Ontario are far weaker than in most other provinces, and many employers know it. A significant change to Ontario law now prohibits non-compete clauses for most employees. Yet these clauses still appear in employment contracts across the province. Many workers still believe they’re binding. Whether you are an employee worried about a clause you signed or an employer trying to protect your business, understanding what’s enforceable is essential before you decide.
What Non-Compete and Non-Solicitation Agreements Actually Do
These clauses, known collectively as restrictive covenants, limit what an employee can do after leaving a job. They come in several forms, and the distinction between them matters enormously because the law treats them very differently.
A non-compete clause restricts an employee from working for a competitor or starting a competing business, usually within a defined geographic area and time period. A non-solicitation clause is narrower: it restricts a former employee from soliciting the employer’s clients, customers, or other employees, but does not prevent them from working in the industry. A confidentiality agreement, or NDA, protects the employer’s trade secrets and confidential information.
Are Non-Compete Agreements in Ontario Enforceable?
For most employees, the answer is now no. Through amendments to the Employment Standards Act under the Working for Workers Act, Ontario prohibited employers from entering into non-compete agreements with employees, effective October 25, 2021. An agreement that violates this prohibition is void.
This was a major shift. Before this change, courts assessed non-competes on a case-by-case basis and often found them unenforceable as unreasonable, but they did not ban them outright. Now, for most employees, statutes prohibit them.
There are two main exceptions. The first is for certain senior executives, specifically those in roles such as chief executive officer, president, chief financial officer, and similar C-suite positions. The second applies in the context of a business sale, where the seller may agree not to compete with the buyer. Outside of these exceptions, a non-compete against a regular employee is generally not enforceable.
How the Different Restrictions Compare
Because the ban applies specifically to non-competes, not other restrictive covenants, it helps to understand how each type is treated. The table below summarizes the current landscape.
| Restriction | What It Restricts | Enforceability in Ontario |
|---|---|---|
| Non-compete | Working for a competitor or starting a competing business | Prohibited for most employees since October 2021, with narrow exceptions |
| Non-solicitation of clients | Contacting or taking former clients or customers | Often enforceable if reasonable in scope and duration |
| Non-solicitation of employees | Recruiting former colleagues to a new employer | Often enforceable if reasonable in scope and duration |
| Confidentiality / NDA | Disclosing trade secrets or confidential information | Generally enforceable and unaffected by the non-compete ban |
This distinction is critical. An employer that can no longer enforce a non-compete may still enforce a well-drafted non-solicitation clause or protect genuine confidential information. Employees should not assume that because non-competes are largely banned, all post-employment restrictions have disappeared.
When Non-Solicitation Clauses Are Enforceable
Non-solicitation clauses were not affected by the non-compete ban and remain enforceable in Ontario, but only if they are reasonable. Courts assess reasonableness based on the restriction’s scope, duration, and the geographic or client range it covers. An overly broad clause, one that lasts too long, or tries to protect more than the employer’s legitimate business interests can be struck down as an unreasonable restraint of trade. Published decisions on CanLII show that courts scrutinize these clauses closely and will not enforce restrictions that go beyond what is necessary.
Importantly, Canadian courts generally will not rewrite an overly broad clause to make it reasonable, a practice sometimes called “blue-pencilling.” If a restriction is unreasonable, courts tend to strike it down entirely rather than narrow it. This means a poorly drafted non-solicitation clause may be just as unenforceable as a banned non-compete.
What Employees Should Do
If you have signed a contract containing a non-compete, do not assume you are bound by it, but do not assume you are free to ignore it either. Whether a clause is enforceable depends on when you signed it, your role, the exact wording, and whether it is truly a non-compete or a non-solicitation clause. Acting on a wrong assumption in either direction can be costly.
Before accepting a new job that might conflict with a restrictive covenant, or before an employer takes action to enforce one, it is worth having the specific clause reviewed. A short consultation can clarify whether the clause is likely enforceable and what your realistic exposure is.
What Employers Should Do
For employers, the non-compete ban means that relying on a non-compete to protect your business is no longer a safe strategy for most of your workforce. The practical response is to protect legitimate business interests through the tools that remain available: carefully drafted non-solicitation clauses, robust confidentiality agreements, and clear policies around intellectual property and trade secrets.
Employers should have their template employment agreements reviewed to ensure they comply with the current law and actually protect what the business needs to protect. A business lawyer or employment lawyer can help redesign agreements so they are both compliant and effective.

Frequently Asked Questions
Are non-compete agreements legal in Ontario?
For most employees, no. Since October 25, 2021, Ontario law prohibits employers from entering into non-compete agreements with employees, and such agreements are void. Limited exceptions apply to certain senior executives and in the context of a business sale. A non-compete signed by a regular employee is generally unenforceable, though the specific circumstances always matter.
I signed a non-compete before October 2021. Does the ban apply to me?
The statutory prohibition applies to non-compete agreements entered into on or after October 25, 2021. Agreements signed before that date are not automatically void under the new law. Still, they remain subject to the longstanding common law rule that restrictive covenants must be reasonable to be enforceable. Many pre-2021 non-competes were already unenforceable because they were overly broad. A lawyer can assess your specific clause and its enforceability.
What is the difference between a non-compete and a non-solicitation clause?
A non-compete clause restricts you from working for a competitor or starting a competing business. A non-solicitation clause is narrower: it restricts you from soliciting your former employer’s clients, customers, or employees, but does not prevent you from working in the industry. This distinction matters because the Ontario ban applies to non-competes, not non-solicitation clauses, which remain enforceable if reasonable.
Can my employer still stop me from taking clients to my new job?
Possibly, through a non-solicitation clause, if you have one and if it is reasonable in scope and duration. Non-solicitation clauses were not affected by the non-compete ban. However, courts will not enforce a clause that is overly broad or that tries to protect more than the employer’s legitimate business interests. Whether a specific clause is enforceable is a fact-specific question worth reviewing with a lawyer before you act.
As an employer, how can I protect my business if I cannot use a non-compete?
Available tools include carefully drafted non-solicitation clauses, strong confidentiality and non-disclosure agreements, and clear intellectual property and trade secret protections. These can be effective when properly drafted, but they must be reasonable to be enforceable. Having an employment lawyer review and update your employment agreements is the most reliable way to protect your business within the current legal framework.
