Employers across Canada often assume that legal liability for harassment begins and ends with their own conduct. This assumption fundamentally misunderstands how human rights law operates. In every Canadian jurisdiction, human rights legislation holds employers responsible not only for harassment they commit directly but also for harassment committed by their employees, supervisors, contractors, and in some circumstances even third parties such as customers or clients. This principle of vicarious or attributed liability represents one of the most significant legal exposures facing business owners, sole proprietors, and non-profit operators, yet it remains poorly understood by many who carry its weight. Understanding when you become legally responsible for what others did in your workplace is essential knowledge for anyone who operates a business or organization with employees in this country.
The foundation of employer liability for harassment rests on the basic principle that employers control the workplace environment. Human rights legislation in Canada imposes a duty on employers to maintain a workplace free from harassment and discrimination. This duty is not passive. It requires employers to take active steps to prevent harassment, to respond appropriately when harassment occurs, and to remedy situations that have resulted in a poisoned work environment. The duty exists because employers have the power to establish workplace policies, to train and supervise employees, to investigate complaints, and to discipline or terminate those who engage in prohibited conduct. Because employers possess this power, the law holds them accountable for exercising it properly.
