Ontario is the strictest province on restrictive covenants. The Working for Workers Act, 2021 added Part XV.1 to the Employment Standards Act, 2000, and section 67.2 prohibits non-compete clauses for most employees, sparing only narrowly defined "chief" executives and sale-of-business sellers. An offer letter that still carries a non-compete for an ordinary hire is not merely unenforceable, it signals legal carelessness. Ontario is also phasing in pay-transparency rules for advertised postings, so salary ranges in offers should align with what was advertised.
British Columbia has no non-compete ban, but its courts apply the common-law reasonableness test rigorously, and a non-compete will almost always lose to a properly drafted non-solicitation clause. BC's Employment Standards Act governs the minimums, and offer letters should reflect its specific notice and vacation provisions rather than borrowing Ontario language wholesale.
Alberta allows restrictive covenants where reasonable and enforces them through the Employment Standards Code, but the same caution applies: a tightly scoped non-solicit beats a broad non-compete every time. Alberta employers should confirm their offer letter's overtime and holiday-pay references track the provincial code.
Quebec stands apart, operating under the Civil Code of Québec and the Act respecting labour standards rather than common-law principles, and it recognizes non-compete clauses subject to strict limits on duration, territory and activity under article 2089. Offer letters for Quebec roles should be reviewed against the Civil Code and ideally issued in French to satisfy the province's language requirements.
Federally regulated employers in banking, telecom and transport must draft to the Canada Labour Code, whose notice and severance scheme differs from the provincial regimes and whose unjust-dismissal provisions give non-managerial employees added protection after twelve months of service.
