Non-Compete Agreements: What Lawyers Need to Know (Tips, Rules, and Pitfalls)

Non-Compete Agreements still matter, but the legal map changed fast. In the U.S., there is no functioning nationwide FTC ban today because a federal court blocked the FTC’s 2024 rule, and the FTC later moved to dismiss its appeal. That leaves firms in a state-law regime, not a national one. In Canada, there is no single national employment-law rule either. The enforceability question is mainly provincial, with Ontario now broadly prohibiting employee non-competes under the Employment Standards Act and other provinces still relying heavily on common law or civil-law reasonableness analysis.

For lawyers, the issue is narrower and more sensitive. Restrictions that may be tolerable in ordinary commercial employment contracts can become ethics problems inside law firms because client choice is central to legal practice. In the U.S., ABA Model Rule 5.6 prohibits agreements that restrict a lawyer’s right to practice after departure, except retirement-benefit arrangements. In Ontario, the Law Society’s guidance on lawyers leaving firms stresses that clients are not the property of the firm and must be free to choose counsel without undue pressure.

What is a non-compete agreement?

A non-compete agreement is a restrictive covenant that limits a worker’s ability to compete after employment ends. It usually restricts the worker by geography, time, line of business, or a combination of all three. Non-solicitation and confidentiality covenants are related, but they are not the same. A non-solicit clause targets customers, staff, or referral sources. A confidentiality clause protects information. A non-compete tries to prevent competitive work itself. That distinction matters because courts and legislatures often treat non-solicits and confidentiality clauses more favorably than true non-competes.

For legal professionals, the drafting mistake is usually overreach. Firms write a covenant broad enough to “feel safe,” then discover that breadth is the reason it fails. Restrictive covenants are enforced, if at all, because they protect a legitimate business interest. They are not enforced merely because the departing worker knows the business well.

U.S. law: no national ban in force, but the state map is stricter than before

The FTC’s 2024 Noncompete Rule would have broadly banned new non-competes nationwide, but the agency’s own press materials now acknowledge that a district court stopped the rule from taking effect and that the FTC later moved to dismiss its appeal. That means U.S. firms still operate under state law unless Congress or another federal rule changes the landscape.

That state-law map is not uniform. California remains the clearest anti-noncompete jurisdiction. The Business and Professions Code section 16600 states that, except for statutory exceptions, every contract restraining anyone from engaging in a lawful profession, trade, or business is void to that extent. Washington does not ban all non-competes, but it imposes statutory thresholds and other limits under chapter 49.62 RCW, including earnings thresholds and protections against out-of-state adjudication or choice-of-law clauses that strip Washington workers of the statute’s protections. Massachusetts allows non-competes under its Noncompetition Agreement Act, but only subject to statutory requirements that include procedural and substantive limits.

For law firms with remote workers or multi-state teams, the practical rule is simple: draft to the most restrictive applicable state, then confirm whether a stricter local rule overrides your contract. Forum and choice-of-law clauses do not always save an overbroad covenant. Washington’s statute expressly voids certain out-of-state law and forum provisions for Washington-based workers.

Canada: no single national rule, but Ontario changed the default

Canada does not have one nationwide employment-law rule on non-competes. Most employment law is provincial. Ontario is now the clearest statutory outlier because the ESA broadly prohibits employers from entering into non-compete agreements with employees, subject to narrow exceptions, including a sale-of-business exception and a defined executive exception. Ontario’s own ESA guide says the law does not prohibit parties from litigating enforceability questions, but the statutory prohibition sharply narrows what employers can validly require in the first place.

Outside Ontario, the analysis is still largely reasonableness-based. In Quebec, the Supreme Court of Canada has drawn an important distinction between restrictive covenants tied to employment and those tied to the sale of a business. In Payette v. Guay Inc., the Court upheld the idea that sale-of-business covenants are assessed differently from ordinary employment restraints because the commercial context changes the balance. In Shafron v. KRG Insurance Brokers, the Court rejected a vague geographic restriction and refused to rescue it through aggressive severance. Those two decisions remain the fastest way to explain Canadian doctrine to clients: context matters, but clarity still matters more.

Canada’s competition law also now criminalizes wage-fixing and no-poach agreements between unaffiliated employers. That is not the same as a one-employer employee non-compete, but it matters for transactions, secondments, shared-service arrangements, and recruitment deals because some clauses that once looked like “standard HR protection” can now trigger competition-law analysis.

Lawyers are different: client choice changes the analysis

For lawyers, non-competes are not just an employment-law problem. They are also a professional responsibility problem.

In the U.S., ABA Model Rule 5.6 states that a lawyer must not participate in offering or making an employment, partnership, shareholder, or similar agreement that restricts the lawyer’s right to practice after termination, except for an agreement concerning retirement benefits. That rule also bars settlement terms restricting a lawyer’s future practice. The point is not simply lawyer mobility. It is the protection of client choice and access to counsel.

Canada does not have one exact national analogue phrased like ABA Rule 5.6, but the regulatory direction is similar. The Federation of Law Societies’ Model Code is implemented in whole or in part across Canadian law societies, and the Law Society of Ontario’s departure guidance says clients are not the property of the firm and must be free to choose their legal representative without undue pressure or influence. For law firms, that means post-departure restrictions that operate as functional non-competes are especially risky even where ordinary employment-law doctrine might tolerate narrower restraints in other industries.

Understanding Non-Compete Clauses: Everything You Need to Know

What usually makes non-compete agreements fail

Most failed non-competes fail for one of five reasons.

The first is overbreadth. If the clause covers too much geography, too much time, too many customers, or too many business lines, courts often refuse enforcement. The second is vagueness. Shafron is still the leading warning that a blurry geographic term can kill the covenant outright. The third is a bad fit. Employers often use non-competes when a narrower non-solicit or confidentiality clause would have been more defensible. The fourth is a poor process. Presenting the covenant at the last minute, without consideration where required, or without a clear business rationale, weakens the file. The fifth is wrong governing law assumptions, especially in cross-border or multi-state teams.

For lawyers, add a sixth: ethics conflicts with client mobility. If a covenant effectively blocks a departing lawyer from serving willing clients, the clause may create regulatory problems even before a court reaches enforceability.

What firms should use instead?

Most law firms are better served by a layered restrictive-covenant strategy than by a broad non-compete.

Use confidentiality language to protect client information, trade secrets, pricing, and internal know-how. Use non-solicitation clauses to address client poaching or employee raiding where local law allows. Use garden-leave or notice-period provisions where lawful and commercially sensible. Use partnership or compensation terms that address transition economics without restricting practice rights. In lawyer departures, use clear client-notification protocols and file-transfer procedures instead of trying to hold clients hostage through contract design.

This is also where software matters. Good matter-management and client-relationship systems reduce the practical fear that drives overbroad restrictive covenants. Firms with clean client ownership data, documented transition workflows, and auditable access controls usually need fewer blunt restrictions.

Practical tips for lawyers and law-firm operators

First, classify the clause before you negotiate it. A surprising number of “non-competes” are really non-solicits or confidentiality provisions with sloppy labels. That matters because courts do not always reward imprecise drafting.

Second, separate the sale-of-business drafting from the employment drafting. Courts in both Canada and the U.S. treat those settings differently. What might survive in an asset sale can fail in an employment contract.

Third, audit by jurisdiction, not by template family. A form bank that works in Texas or New York may be dead on arrival in California or Ontario.

Fourth, if the worker is a lawyer, test the clause against professional-conduct rules before you test it against employment law. Client choice and lawyer mobility are not afterthoughts. In many firms, they are the first issue.

Frequently Asked Questions

Are non-compete agreements legal in the U.S.?
Sometimes. There is no effective nationwide FTC ban today because the FTC rule was blocked, and the appeal was later withdrawn. Enforceability now depends mainly on state law. California broadly voids most employment non-competes, while states like Washington and Massachusetts regulate them through statutes.

Are non-compete agreements legal in Canada?
Sometimes. Canada has no single national employment-law rule. Ontario broadly prohibits employee non-competes with narrow exceptions. Elsewhere, enforceability is usually judged under provincial common law or Quebec civil law reasonableness principles.

Can law firms use non-competes against lawyers?
That is risky. In the U.S., ABA Model Rule 5.6 broadly prohibits agreements that restrict a lawyer’s right to practice after departure, except retirement-benefit arrangements. In Ontario, the Law Society guidance emphasizes that clients are not the property of the firm and must be free to choose counsel.

What is safer than a non-compete for most firms?
Usually, a combination of confidentiality, non-solicitation, notice-period planning, and clean client-transition procedures. Those tools are often easier to justify and easier to enforce than a broad post-employment non-compete.

Does the sale of a business change the analysis?
Yes. Courts often view sale-of-business restraints more favorably than employment restraints. In Canada, Payette is the leading Supreme Court decision on that distinction.

Can violating a non-compete send someone to jail?
Ordinary breach of a non-compete is generally a civil issue, not a criminal one. The bigger practical risks are injunctions, damages, fee exposure, and business disruption. Competition-law issues like Canada’s no-poach prohibition are different and can trigger separate legal consequences.
