The relationship between an employer and an employee in Canada rests on a foundation of mutual obligation, and the law has long recognized that when an employer brings that relationship to an end, certain rules govern how that termination must occur. Wrongful dismissal is one of the most frequently misunderstood concepts in Canadian employment law, not because it is inherently complex, but because the term itself creates confusion. Many business owners, sole proprietors, and non-profit operators assume that wrongful dismissal involves some form of moral wrongdoing or unfair treatment by the employer. In reality, the concept is far more technical and, in some ways, far narrower than popular understanding suggests. Understanding what wrongful dismissal actually means under Canadian law is essential for anyone who employs others, whether that employment relationship involves a single part-time assistant or a team of dozens across multiple locations.
At its core, wrongful dismissal is a contractual claim. It arises when an employer terminates an employee without providing the notice or compensation to which the employee is legally entitled. The word wrongful does not refer to the reason for the dismissal being unjust, discriminatory, or unfair in any colloquial sense. Instead, it refers to a breach of the employment contract, whether that contract is a formal written agreement or an implied agreement that arises from the employment relationship itself. Every employment relationship in Canada involves a contract, even when no written document exists. When an employer hires someone, promises are made about wages, duties, hours, and the nature of the relationship. The law implies additional terms into that contract, including the term that if the employer wishes to end the relationship without cause, the employee is entitled to reasonable notice of termination or pay in lieu of that notice. Wrongful dismissal occurs when the employer fails to provide that notice or compensation.
