Non-Compete Clauses in an Ontario Partnership Agreement
Carefully distinguishes partner-to-partner restrictive covenants (assessed under common-law reasonableness) from employee non-competes (banned under the ESA since October 2021), covering scope/duration/geography analysis and non-compete vs. non-solicit.
Key Takeaways
- Restrictive covenants between business partners are generally assessed under ordinary common-law reasonableness principles, not the employee non-compete ban.
- Ontario’s Employment Standards Act, 2000 has banned most employee non-competes since October 2021 — but that ban generally doesn’t extend to partner-to-partner agreements.
- Courts assessing a partner non-compete generally look at scope of activity restricted, geographic reach, and duration, asking whether the restriction goes no further than necessary to protect a legitimate interest.
- Non-solicitation clauses, which restrict poaching clients or other partners rather than competing outright, are often viewed as a less restrictive and more easily upheld alternative.
- An overly broad non-compete — in geography, duration, or scope — risks being found unenforceable by a court, even in the partner-to-partner context where the employee ban doesn’t apply.
- This article explains how these clauses are generally analyzed — it’s general information, not legal advice for your specific situation.
Two different legal regimes — don’t mix them up
It’s easy to assume that any “non-compete” in Ontario is governed by the same rules, especially given how much attention Ontario’s ban on employee non-competes has received since it came into effect. But a restrictive covenant between business partners — restricting a departing partner from competing with the partnership or poaching its clients — sits in a genuinely different legal category from an employee non-compete, and the two shouldn’t be conflated.
Employee non-competes are governed by Ontario’s Employment Standards Act, 2000, which has, since October 2021, generally prohibited employers from including non-compete agreements in employment contracts, subject to narrow exceptions (most notably around the sale of a business and certain executive roles). That statutory ban is specific to the employer-employee relationship.
A restrictive covenant between partners in a partnership — governed by Ontario’s Partnerships Act and the partnership agreement itself — is a different relationship entirely, and is generally assessed under the common law of restrictive covenants that Ontario courts have applied to business owners and commercial parties for a long time, independent of the employee-specific statutory ban.
Why the ESA’s employee non-compete ban doesn’t apply here
The Employment Standards Act, 2000’s restriction on non-competes is specifically targeted at the employer-employee relationship — it’s meant to prevent employers from using non-compete clauses to restrict employees’ ability to find new work. A partner in a partnership is generally not an employee of that partnership; partners are co-owners of the business, with a fundamentally different legal relationship to it than an employee has to an employer.
Because of this, a restrictive covenant in a partnership agreement — restricting a departing partner from competing with the business or soliciting its clients after they leave — generally isn’t subject to the ESA’s employee non-compete ban at all. Instead, it falls under the pre-existing common-law framework that applies to restrictive covenants between business owners, commercial parties, and in the sale-of-business context.
Don’t conflate the two
How reasonableness is generally assessed
Under the common-law approach that applies to partner-to-partner restrictive covenants, courts generally start from the position that restraints on a person’s ability to work or compete are viewed with some skepticism, but can be upheld where they’re reasonable and protect a legitimate business interest. The analysis typically focuses on three dimensions: the scope of activity restricted, the geographic area covered, and the duration of the restriction.
A restriction that’s narrowly tailored — for example, preventing a departing partner from operating a directly competing business within a specific, reasonably sized geographic area for a limited, clearly justified period — stands a better chance of being upheld than a broad, open-ended restriction covering an entire industry, an unlimited geography, or an indefinite duration.
Courts also generally look at whether the restriction is actually protecting a legitimate interest, such as client relationships the partnership built up, confidential business information, or goodwill the departing partner helped develop while a partner — rather than simply trying to prevent ordinary competition for its own sake. A restriction aimed at punishing a departing partner, rather than protecting a specific interest, is less likely to be upheld.
Non-compete vs. non-solicitation clauses
Partnership agreements often include both non-compete and non-solicitation clauses, and it’s worth understanding the difference. A non-compete clause generally restricts a departing partner from engaging in a competing business altogether within a defined scope and area. A non-solicitation clause is narrower — it generally restricts the departing partner from actively pursuing the partnership’s existing clients, or from poaching the remaining partners’ staff, without necessarily barring them from the industry entirely.
Because a non-solicitation clause is less restrictive of a departing partner’s ability to earn a living in their field, courts often view it as easier to justify than a full non-compete, though it’s still subject to the same underlying reasonableness analysis. Many partnership agreements use a layered approach — a shorter, narrower non-compete combined with a somewhat longer non-solicitation restriction — to balance protecting the partnership’s interests against unduly restricting a departing partner.
Which combination actually makes sense depends heavily on the nature of the business — whether client relationships are central to its value, whether the business depends on specialized knowledge, and how competitive the relevant market actually is. See our guide to fiduciary duties between business partners for how these restrictions relate to partners’ broader obligations to each other.
Drafting considerations for partnership agreements
Because reasonableness is assessed on the specific facts and specific wording, vague or generic restrictive covenant language tends to create more risk than it resolves. A clause that simply states a departing partner “shall not compete” without defining the activity, geography, or duration leaves considerable uncertainty about what it actually covers — and gives a court less to work with in deciding whether it’s reasonable.
Partners drafting these clauses generally benefit from defining the restricted activity precisely (for example, by reference to the specific services the partnership provides), setting a geographic scope tied to where the partnership actually operates or draws clients from, and choosing a duration proportionate to how long it would reasonably take the partnership to rebuild the relevant client relationships or adjust to the partner’s departure.
It’s also worth coordinating a restrictive covenant with the partnership’s broader exit and buyout provisions. Our guide to partnership agreements in Ontario covers how exit provisions generally fit together with the rest of the agreement, and how a buyout and a restrictive covenant often operate side by side when a partner leaves.
What happens if a clause is challenged
If a departing partner later competes despite a restrictive covenant, and the remaining partners seek to enforce it, a court will generally examine the clause’s reasonableness as of the time it was agreed to, considering the scope, geography, and duration against the legitimate interest it was meant to protect. If the court finds the clause reasonable, it can be enforced, potentially through an injunction stopping the competing activity, as well as damages.
If the court instead finds the clause unreasonably broad, the consequences can be more severe than simply narrowing it down to something fair. Ontario courts have, in various contexts, declined to “blue-pencil” an overly broad restrictive covenant into a reasonable one, instead striking the clause entirely — leaving the partnership without any contractual restriction on the departing partner’s competition at all.
This risk is precisely why careful, specific drafting matters so much for these clauses. Our Partnerships hub and our guide to common partnership disputes in Ontario cover related issues that often arise when a partner’s departure turns contentious.
Timing and context matter to the analysis
The circumstances surrounding a restrictive covenant also factor into how a court assesses it. A clause negotiated at the outset of the partnership, when all partners had roughly equal bargaining power and the opportunity to negotiate its terms, is generally viewed differently than a clause introduced later, under pressure, as a condition of one partner continuing to participate in the business or receiving a buyout.
Context connected to a buyout is particularly common in practice. When a partnership buys out a departing partner’s interest, the parties often negotiate a restrictive covenant as part of that same transaction, reflecting that the departing partner is being compensated in exchange for agreeing not to compete. Courts have sometimes shown more willingness to enforce a restrictive covenant tied to this kind of transaction, recognizing that value was exchanged specifically for the restriction, though the underlying reasonableness analysis still applies.
Because the specific circumstances matter so much, partners negotiating a restrictive covenant — whether at formation or on a partner’s exit — generally benefit from documenting not just the clause itself but the context behind it: what legitimate interest it’s meant to protect, and why the specific scope, geography, and duration chosen were considered reasonable at the time. That context can matter significantly if the clause is ever challenged later.

FAQ
Frequently asked questions
Are non-compete clauses between business partners legal in Ontario?
Generally, yes — unlike most employee non-competes, which Ontario’s Employment Standards Act, 2000 has banned since October 2021, a restrictive covenant between business partners is typically assessed under ordinary common-law reasonableness principles, not under that statutory ban. A partner non-compete can be enforceable if it’s reasonable in scope, duration, and geography and protects a legitimate business interest.
Does the Ontario non-compete ban for employees apply to business partners?
No — the relevant provisions of the Employment Standards Act, 2000 apply to the employer-employee relationship, and a partner in a partnership is generally not an employee of the partnership for this purpose. A restrictive covenant between partners falls instead under the common-law framework that courts have long applied to agreements between business owners.
What makes a partner non-compete clause enforceable in Ontario?
Courts generally look at whether the restriction protects a legitimate business interest — such as client relationships or confidential information — and whether its scope, geographic area, and duration go no further than necessary to protect that interest. A clause that’s broader than needed, in any of these dimensions, risks being found unreasonable and unenforceable.
How long can a non-compete last between partners in an Ontario partnership agreement?
There’s no fixed statutory limit for partner-to-partner restrictive covenants, since they’re assessed on reasonableness rather than a bright-line rule. Courts generally consider whether the specific duration is proportionate to the legitimate interest being protected, with shorter, more clearly justified periods generally standing on firmer ground than lengthy, open-ended restrictions.
Can a departing partner be restricted from contacting former clients in Ontario?
Often, yes — a non-solicitation clause restricting a departing partner from actively soliciting the partnership’s clients for a defined period is a common and generally more readily enforceable alternative to a full non-compete, since it restricts specific conduct rather than the ability to work in the field at all. Whether a particular clause is actually enforceable still depends on its own specific wording and reasonableness.
What’s the difference between a non-compete and a non-solicitation clause for partners?
A non-compete clause generally restricts a departing partner from engaging in a competing business altogether, within a defined scope, geography, and time period. A non-solicitation clause is narrower, generally restricting the departing partner from actively pursuing the partnership’s clients, customers, or remaining partners, without necessarily barring them from the industry entirely.
Can a non-compete clause in a partnership agreement be found unenforceable in Ontario?
Yes — if a court finds that a restrictive covenant is broader than necessary to protect a legitimate interest, whether in geographic scope, duration, or the range of activity restricted, it can decline to enforce the clause. Some courts have also declined to simply narrow an overly broad clause down to something reasonable, instead striking it entirely, which raises the stakes of getting the scope right at the drafting stage.
Do non-compete clauses between partners need to be in writing in Ontario?
As a practical matter, yes — while an oral restrictive covenant could theoretically be argued, proving its specific terms without a written record is extremely difficult, and a court is unlikely to enforce a restriction it can’t pin down with reasonable certainty. Partner non-compete and non-solicit clauses are generally included directly in a written partnership agreement for exactly this reason.
Can a partnership agreement restrict a partner from competing while still a partner?
Generally, yes — separately from any post-departure restrictive covenant, partners typically owe each other fiduciary duties of good faith and loyalty while the partnership continues, which can itself restrict a partner from competing directly with the partnership during that time. A written agreement can also set out explicit terms governing outside business activities while the partnership relationship is ongoing.
Is a non-compete clause between partners treated the same as one in a business sale agreement?
Not necessarily — courts have sometimes applied a somewhat more permissive view toward restrictive covenants given in connection with the sale of a business (including a partnership interest) compared to those imposed purely in an ongoing employment relationship, recognizing that the seller received value in exchange for the restriction. A partner non-compete tied to someone exiting and being bought out may be analyzed with that context in mind, though reasonableness still governs.
What should partners consider when drafting a non-compete clause in their partnership agreement?
Partners generally benefit from defining the restricted activity, geography, and duration as precisely and narrowly as the legitimate business interest actually requires, rather than using broad, generic language. Tying the restriction to a clear, articulable interest — such as protecting specific client relationships or confidential business information — tends to support enforceability if the clause is ever challenged.
Can a partner challenge a non-compete clause after leaving the partnership in Ontario?
Yes — a departing partner can challenge the enforceability of a restrictive covenant in court, typically arguing that it’s broader than necessary to protect a legitimate interest, or that it was never properly agreed to. Whether such a challenge succeeds depends heavily on the specific wording of the clause and the circumstances surrounding its creation.
