Non-solicitation clauses occupy a distinct and often misunderstood space in Canadian employment law, sitting between the outright geographic and temporal restrictions of non-compete agreements and the more information-focused protections of confidentiality provisions. These clauses aim to prevent departing employees from actively pursuing the employer's established relationships, whether those relationships exist with customers, clients, or fellow employees. Understanding how these clauses function, when they are enforceable, and what distinguishes a reasonable restriction from an unenforceable one is essential for any business owner, professional, or non-profit operator who relies on relationship-based value creation.
The legal foundation for non-solicitation clauses in common law provinces derives from the same doctrine of restraint of trade that governs all restrictive covenants in employment. Courts across British Columbia, Alberta, Saskatchewan, Ontario, and most other common law provinces presume that any agreement restricting a person's ability to earn a living after employment ends is contrary to public policy. This presumption means that the party seeking to enforce such a restriction, typically the employer, bears the burden of demonstrating that the clause is reasonable in the circumstances. Reasonableness is assessed at the time the contract was made, not at the time of enforcement, and must balance the employer's legitimate proprietary interests against the potential hardship to the employee and the broader public interest in maintaining a competitive marketplace where workers can move freely between opportunities.
