Canadian employers face significant legal exposure when harassment or violence occurs in their workplaces, and this exposure extends far beyond the direct actions of the employer themselves. The legal framework governing workplace harassment and violence in Canada creates a complex web of obligations that, when breached, can result in substantial liability for employers regardless of whether they personally participated in or even knew about the harmful conduct. Understanding this liability framework is essential for any business owner, operator, or organizational leader because the consequences of failing to prevent, address, or properly respond to workplace harassment and violence can include regulatory penalties, civil damages, increased insurance premiums, reputational harm, and in some circumstances, personal liability for directors and officers.
The foundation of employer liability for workplace harassment and violence rests on both statutory obligations and common law principles that have developed over many decades. Every Canadian jurisdiction has enacted occupational health and safety legislation that explicitly requires employers to maintain workplaces free from harassment and violence. These statutory regimes treat psychological safety with the same seriousness as physical safety, recognizing that harassment and workplace violence cause genuine harm to workers that employers have a duty to prevent. In Ontario, the Occupational Health and Safety Act, as of the date of authorship, defines workplace harassment as engaging in a course of vexatious comment or conduct against a worker that is known or ought reasonably to be known to be unwelcome, and it requires employers to develop and maintain policies and programs addressing both harassment and violence. British Columbia's Workers Compensation Act and associated regulations impose similar obligations through WorkSafeBC, requiring employers to take reasonable steps to prevent workplace bullying and harassment. Alberta's Occupational Health and Safety Act, as of the date of authorship, mandates that employers ensure the health and safety of workers, which the courts and regulators have interpreted to include psychological health. Saskatchewan's Saskatchewan Employment Act creates parallel duties, while Quebec approaches these matters through both the Act respecting occupational health and safety and the Civil Code of Quebec, which establishes a distinct framework rooted in civil law principles that impose a general duty on employers to protect the dignity and psychological integrity of workers. The federal Canada Labour Code applies to federally regulated workplaces such as banks, telecommunications companies, interprovincial transportation, and federal Crown corporations, and it contains comprehensive provisions addressing workplace harassment and violence that came into significant effect following amendments in January 2021.
