The enforceability map has shifted dramatically. Ontario's Working for Workers Act amended the Employment Standards Act to prohibit employer-employee non-compete agreements entered into on or after October 25, 2021, excepting only genuine executives (chief-officer level) and covenants given on the sale of a business — making most new Ontario non-competes void from the start. In the US, California Business & Professions Code §16600 has long voided employee non-competes, and 2024 amendments (§16600.5, AB 1076) go further: attempting to enforce one is now itself unlawful, with employee remedies including damages and attorney's fees. Minnesota, Oklahoma, and North Dakota ban most non-competes; Washington, Colorado, Illinois, and others impose salary thresholds below which they are void.
The FTC's 2024 rule that would have banned non-competes nationwide was set aside by a federal court in Texas before its effective date, so US enforceability remains state-by-state. Everywhere else in Canada and the reasonableness-test US states, courts start from the position that a non-compete is a restraint of trade — presumptively unenforceable unless the employer proves it is no broader than necessary in duration, geography, and restricted activity to protect a legitimate business interest.
Three doctrines do most of the work. Consideration: a covenant signed mid-employment needs fresh value — a raise, bonus, promotion, or equity — and in many jurisdictions continued employment alone is not enough, which can void the clause regardless of its scope. Severance: many US courts will 'blue-pencil' or judicially narrow an overbroad clause down to something enforceable, but Canadian courts largely refuse — the Supreme Court of Canada held in Shafron v KRG Insurance (2009) that ambiguous or overbroad covenants fail outright rather than being rewritten, which makes drafting overreach fatal in Canada. Legitimate interest: enforceability scales with what the employee could actually take — client relationships and trade secrets — which is why courts routinely refuse to enforce non-competes against junior staff.
This also explains the enforceability gap between clause types. Non-solicitation clauses (don't poach clients or staff) protect a specific interest without barring someone from earning a living, so courts enforce them far more readily than non-competes — Canadian courts often ask whether a non-solicit would have been enough before enforcing any non-compete at all. Confidentiality obligations are the most durable of all, surviving under trade secrets law (including the US Defend Trade Secrets Act) even where every covenant fails.
A cease-and-desist letter is a pressure instrument, not a court order — employers routinely send them over clauses they know are shaky, because many recipients comply out of fear. The right response is neither silence nor capitulation: a lawyer-drafted reply that contests enforceability, avoids admissions, and signals you will defend an injunction application changes the economics for the employer. If a lawsuit is actually filed, timelines compress to days — interim injunction hearings decide whether you can keep working while the case proceeds, so counsel must be retained immediately.
The cheapest fix is negotiating before you sign. At the offer stage you can shorten duration (12 months is the practical ceiling in most reasonableness jurisdictions), narrow geography to where you will actually work, limit restricted activities to your actual role, or convert the restriction into paid garden leave — the UK-style arrangement, increasingly used in North America and required for Massachusetts non-competes (50% of salary during the restriction), where the employer pays you to sit out. An employer unwilling to pay for the restriction is telling you what it is really worth.
