Violence and harassment in Ontario workplaces are not rare exceptions-they are real, recurring risks that demand immediate attention. You are legally required to have a written policy, even with just one employee. Failing to comply can result in significant fines, and exposes your workers to preventable harm. Your responsibility includes assessment, prevention, and training-every sector, every workplace, every time.
Key Takeaways:
- Employers in Ontario must have a written workplace violence and harassment policy, review it at least annually, and make it readily available to all employees, a requirement that applies regardless of company size or industry.
- Workplace harassment under Ontario law includes engaging in a course of vexatious comment or conduct that is known or ought reasonably to be known to be unwelcome, with examples ranging from persistent offensive jokes to targeted social exclusion.
- When violence or harassment is linked to domestic violence that spills into the workplace, employers have a legal duty to take corrective action, such as adjusting work schedules or enhancing security, if they become aware of the risk.
The Law of the Land
Ontario’s Occupational Health and Safety Act mandates that employers address workplace violence and harassment as part of their legal duty. You must have a written policy, review it annually, and implement it through training and clear reporting procedures. Failure to comply can result in orders from the Ministry of Labour, fines, or prosecution, especially after incidents tied to negligence. A 2016 amendment explicitly extended protections to domestic violence spilling into the workplace, recognizing its unique risks. Your obligations are not optional, and the law holds you accountable even when threats originate outside the office. A mid-sized SaaS firm faced public enforcement action after ignoring repeated warnings about a client’s threatening behaviour, underscoring the real consequences of non-compliance.
The Nature of the Conflict
Every incident of workplace violence or harassment begins with a specific trigger, whether it’s a dispute over work conditions, personal grievances, or external stressors entering the workplace. You must recognize that conflict is not inherently violent, but unchecked tension can escalate quickly. A disagreement between two employees over shift assignments, for example, may seem minor but can deepen if communication breaks down. Your role is to identify the root cause early, not just address surface behavior. Patterns of intimidation, written threats, or sudden emotional outbursts signal higher risk and require immediate documentation and response.
Assessing the Danger
Recognize that not all threats manifest verbally or physically; some emerge through patterns of behavior such as repeated boundary violations or unexplained absences after conflicts. You must review past incidents, even minor ones, as they may signal escalating risk. A worker who isolates themselves following a dispute may be in distress. Consult resources like the Workplace Violence and Harassment guidance from the Institute for Work & Health to identify red flags. Early intervention can prevent harm, especially when supervisors are trained to spot subtle changes in conduct.
The Formal Complaint
When an incident occurs, you must provide a clear path for employees to file a formal complaint without fear of reprisal. Your policy should outline the steps for submitting a complaint, including to whom it should be directed and the expected timeline for response. A designated, trained investigator must review the claim promptly and maintain confidentiality to protect all parties involved. Failure to act on a formal complaint can result in significant legal penalties and damage to workplace trust. For guidance on meeting your obligations, review Ontario Mandatory Workplace Harassment Training requirements at Ontario Mandatory Workplace Harassment Training requirements.
Training for Action
Your organization must provide regular, documented training that equips employees and supervisors to recognize, respond to, and report incidents of workplace violence and harassment. All staff, including part-time and temporary workers, are entitled to this instruction. A mid-sized SaaS firm in Kitchener, for example, reduced incident recurrence by reinforcing annual sessions with quarterly scenario drills. Failure to deliver consistent training can result in fines or orders from the Ministry of Labour.
Violence from the Home
When personal conflicts extend into the workplace, you must act swiftly to protect employees. A partner or family member showing up unannounced at your office poses a direct threat to safety and triggers your duty under Ontario law to investigate and respond. You are required to assess whether domestic tensions could escalate on-site, especially if there are prior incidents or police involvement. Restraining orders or recent threats make the risk imminently higher. Your prevention plan must include procedures for handling such intrusions, coordinating with law enforcement when necessary, and offering support to affected staff. Ignoring these signs exposes your team to harm and your organization to legal liability.
Final Words
You must treat workplace violence and harassment policies as living documents, actively reviewed and updated to reflect changes in staff, operations, or incidents. Ontario law requires annual reviews, but effective employers revisit their policies more often, especially after a complaint or near-miss event. A construction company in Hamilton revised its protocol within weeks of an altercation, incorporating new de-escalation procedures that prevented further incidents for over two years.
FAQ
Q: What legal obligations do Ontario employers have regarding workplace violence and harassment policies?
A: Employers in Ontario must develop, maintain, and review a written workplace violence and harassment policy under the Occupational Health and Safety Act. The policy must be reviewed at least every three years and posted in a conspicuous location or provided to employees upon request. A mid-sized SaaS firm in Kitchener, for example, was cited for non-compliance after an inspection revealed its policy had not been updated since 2018 and was not readily accessible to staff. Employers with six or more employees must also have the policy in writing and ensure all new hires receive a copy as part of onboarding.
Q: Does the law cover harassment that originates outside the workplace, such as domestic violence?
A: Yes, Ontario’s legislation explicitly requires employers to assess risks associated with domestic violence when it may spill into the workplace. If an employee is experiencing domestic conflict and there is a potential threat at work, the employer must take preventive steps. A manufacturing supervisor in Windsor was placed on administrative leave after a restraining order was issued by their partner, prompting the company to reassess site access protocols and coordinate with local law enforcement. The employer updated its internal risk assessment within 48 hours to reflect the new circumstances.
Q: How often must employees receive training on workplace violence and harassment policies?
A: Training must be provided to all employees and supervisors as soon as practicable after they are hired and whenever the policy is updated. A retail chain in Ottawa revised its training program in 2022 after updating its harassment policy to include cyberbullying and remote work scenarios. All 1,200 frontline staff completed the revised module within three months, with supervisors receiving an additional session on identifying early warning signs of psychological harassment. The employer documented completion dates and stored records for audit purposes, aligning with Ministry of Labour expectations.
