The doctrine of condonation represents one of the most significant yet underappreciated legal pitfalls facing Canadian employers who discover employee misconduct. At its core, condonation occurs when an employer, having learned of conduct that would otherwise justify termination for cause, continues the employment relationship without taking meaningful disciplinary action within a reasonable time. Through this continuation, the employer is deemed to have forgiven or waived the misconduct, permanently losing the right to rely upon that conduct as grounds for dismissal. The principle operates as a form of estoppel, preventing employers from stockpiling instances of misconduct to deploy strategically at some later date when termination becomes convenient for other reasons. Canadian courts have consistently held that employers must act with reasonable promptness when responding to employee misconduct, and failure to do so can transform what would have been a valid cause termination into a wrongful dismissal entitling the employee to significant damages.
The legal foundation for condonation rests in the common law principles governing the employment relationship across most Canadian provinces, including British Columbia, Alberta, Saskatchewan, Ontario, and the Atlantic provinces. The doctrine reflects the broader principle that employment is a continuing relationship requiring ongoing mutual obligations of good faith and fair dealing. When an employer discovers misconduct but continues to accept the employee's services, provide regular compensation, and otherwise treat the employment relationship as ongoing, the law presumes that the employer has elected to treat the conduct as insufficient to warrant termination. This presumption arises because employees are entitled to reasonable certainty about their employment status, and it would be fundamentally unfair to allow employers to hold misconduct in reserve as a perpetual threat. In Quebec, while the Civil Code of Quebec governs employment relationships rather than common law, similar principles apply through the requirement of good faith in contractual relationships established under articles 6, 7, and 1375 of the Civil Code of Quebec, as of the date of authorship. Quebec employers who tolerate misconduct may similarly find themselves unable to subsequently rely upon that conduct to justify termination, as the principle of good faith requires parties to act consistently and not to exercise rights in a manner that is excessive or unreasonable given their prior conduct.
