Non-compete agreements in Canada: Ontario's ban, Quebec's rules, and what employers can still use

What a non-compete is — and what it isn't

A non-compete (non-competition) clause is a promise that after the employment relationship ends, the employee won't work for a competitor or start a competing business — usually within a defined area and for a defined time. Employers use them to protect client relationships, trade secrets, and the investment they've made in training.

It is routinely confused with two different restrictions. A non-solicitation clause doesn't stop you from working for a competitor — it stops you from actively poaching your former employer's clients or employees for a reasonable period. A confidentiality clause (or NDA) stops you from using or disclosing secret information, during and after employment. The three do different jobs, face different legal tests, and — critically in Ontario — only one of them is banned.

Ontario: the ban

Ontario is the first — and so far only — Canadian jurisdiction to ban non-competes by statute. The Working for Workers Act, 2021 (Bill 27, which received third reading on November 30, 2021) added Part XV.1 to the Employment Standards Act, 2000. Section 67.2(1) provides that no employer shall enter into an employment contract or other agreement with an employee that is, or that includes, a non-compete agreement. The provision was deemed in force on October 25, 2021.

The statutory definition is broad: an agreement, or any part of an agreement, between an employer and an employee that prohibits the 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 ends. Any non-compete that violates the prohibition is void — it has no legal effect whatsoever.

Two timing points matter. First, the ban applies to contracts entered into on or after October 25, 2021. The Ministry of Labour's position is that it does not reach agreements signed before that date — those live or die under the old common-law reasonableness test. Second, the ban covers renewals and new agreements, so an employer can't resurrect a void clause by having a long-serving employee 're-sign' their contract.

Ontario's two narrow exceptions

The ban has exactly two exceptions, and both are construed narrowly:

• Executives. Section 67.2(4) carves out employees who are executives — defined as any person holding the office of 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, or any other chief executive position. A vice-president, director, or senior manager doesn't qualify, and courts and the Ministry look at substance over titles: handing someone a 'Chief' title to smuggle in a non-compete won't survive scrutiny
• Sale of a business. Where a business (or part of one) is sold or leased and the seller agrees not to compete with the purchaser's business after the sale — and immediately after the sale the seller becomes an employee of the purchaser — the prohibition doesn't apply. This protects the value of what the buyer paid for; it doesn't create a back door for ordinary employee non-competes

Everyone else — the salesperson, the developer, the account manager, the technician — cannot lawfully be bound by a non-compete in Ontario, no matter how the clause is worded or what consideration was offered.

Quebec: article 2089's strict requirements

Quebec never banned non-competes, but its Civil Code polices them through article 2089, which sets four cumulative conditions. A non-compete must be stipulated in writing and in express terms; it must be limited as to time, place, and type of employment; each of those limits must go no further than necessary to protect the employer's legitimate interests; and the burden of proving all of this falls on the employer — not the employee.

In practice, Quebec courts apply these requirements rigorously. Ambiguity in any single element — an unclear territory, a fuzzy job description — can render the entire clause unenforceable, because the court can't assess whether the clause as a whole is reasonable. And courts won't rewrite an overbroad clause to make it valid; they strike it down. Case law has also refused to enforce non-competes where the employer terminated the contract without a serious reason, or where the employee left for a serious reason attributable to the employer.

The drafting lesson for Quebec employers: name a precise duration (months, not 'a reasonable period'), a precise territory (named cities or a defined radius, not 'wherever we do business'), and a precise set of restricted activities tied to the employee's actual role and the secrets they actually touched. Anything aspirational gets cut.

The rest of Canada: the reasonableness test

In British Columbia, Alberta, Manitoba, and the other common-law provinces, non-competes remain enforceable in principle — but Canadian courts have never liked restraints on earning a living, and they interpret these clauses narrowly against the employer who drafted them.

The test, applied case by case, asks whether the restraint goes further than reasonably necessary to protect a legitimate proprietary interest. Courts weigh three dimensions: geographic scope (is the territory limited to where the employer actually competes?), duration (is the time period the minimum needed — months rather than years?), and the activities restricted (does it target the employee's actual competitive threat, or bar them from their entire profession?). The employer must show a real interest worth protecting — genuine trade secrets, or client relationships the employee personally built — not just a general desire to hobble a departing worker.

Overbroad clauses fail, and courts won't blue-pencil them into something reasonable. A Canada-wide, two-year ban on 'any competitive activity' for a junior employee is the textbook example of a clause that dies on arrival. Ambiguity is equally fatal: if the clause doesn't clearly say what 'competing' means or where the boundary runs, the employer loses.

What employers should use instead

The ban and the case law don't leave employers defenceless — they just force precision. The modern post-employment toolkit protects what actually needs protecting:

• Non-solicitation of clients: bar the former employee from actively soliciting clients they served, for a defined period (commonly 6–12 months). In Ontario this is expressly outside the non-compete ban
• Non-solicitation of employees: bar poaching of colleagues, which protects team stability without restricting anyone's right to work
• Confidentiality / NDA: protect genuine trade secrets and confidential information during and after employment — enforceable everywhere when properly scoped
• Intellectual property assignment: make clear the company owns work product created on the job
• Notice and garden-leave provisions: keep a departing key employee on payroll (and out of the market) during a defined notice period instead of restricting them after it

Each of these must still be reasonable in scope and duration, and each should be supported by consideration — but unlike a blanket non-compete, they target real risks and survive judicial scrutiny.

Playbook: if you're asked to sign

For employees and new hires, work through this checklist before signing anything with post-employment restrictions:

• Identify which restriction you're actually signing: non-compete, non-solicitation, confidentiality, or a bundle — they face different tests
• In Ontario, check the date and your role: a non-compete in a contract signed on or after October 25, 2021 is void unless you're a genuine C-suite executive or selling your business
• In Quebec, test the clause against article 2089: is it written, express, and precisely limited in time, place, and activity?
• Elsewhere, ask whether the scope, duration, and geography are broader than the employer's real competitive footprint
• Check for fresh consideration: a restriction added mid-employment generally needs something new (a raise, bonus, or promotion), not just continued employment
• Never refuse or breach on a hunch — have an employment lawyer review the actual wording first, especially if significant compensation or a signing bonus is tied to it

For employers drafting these clauses: pick the narrowest restriction that protects your real interest, define every term precisely, give fresh consideration for mid-employment changes, and in Ontario, stop putting non-competes in non-executive contracts entirely — a void clause plus an overconfident enforcement letter is how companies end up paying the other side's legal costs.

Mid-employment non-competes and fresh consideration

A recurring trap: the employee signs a clean offer letter, works for three years, then gets a promotion package containing a new non-compete 'as a condition of the promotion.' Under long-standing contract principles, a new restraint imposed mid-employment needs fresh consideration to be enforceable — something of value beyond the continued employment the worker already had. A genuine raise, bonus, or promotion can supply it; a pizza lunch and a new title cannot.

In Ontario this issue now mostly matters for the two exceptions (executives and sale-of-business), since other mid-employment non-competes are void regardless. In Quebec and the common-law provinces, it remains live: an employer that slides a restriction into a routine 'updated handbook acknowledgement' with no new benefit to the employee is building on sand.
