Restrictive Covenants — Ontario Employment Law

Restrictive covenants are clauses in an employment contract designed to restrict an employee's activities after their employment ends. Employers use them to protect legitimate business interests, such as confidential information, client relationships, and trade secrets. In Ontario, the three most common types are non-competition, non-solicitation, and confidentiality clauses. However, from a legal standpoint, these clauses are not automatically enforceable. The courts start with the presumption that any clause restricting a person's ability to earn a living is a restraint of trade and is therefore void.

The burden falls on the employer to prove the covenant is 'reasonable' and necessary. To be considered reasonable, the clause must be carefully limited in its temporal duration (how long it lasts), geographic scope (the area it covers), and the scope of activities it prohibits. A clause that is overly broad or ambiguous will almost certainly be struck down by a court. For instance, a Canada-wide, five-year ban on working in an entire industry would be unenforceable. Courts will not rewrite an unreasonable clause to make it reasonable; they will simply invalidate it.

A significant development in Ontario law is the amendment to the Employment Standards Act, 2000 (ESA), which now explicitly prohibits employers from entering into non-competition agreements with most employees. There are very narrow exceptions, primarily for certain high-level executives and in the context of the sale of a business. This ban does not apply to non-solicitation clauses, which prevent an ex-employee from poaching clients or employees, but these still must meet the common law test of reasonableness. Given the complexity and the shifting legal landscape, understanding how a restrictive covenant in your contract might be interpreted requires a careful analysis of your specific circumstances and the precise wording of the agreement.
