If an employee claims you punished them for raising a health and safety concern, you may be facing an unjust reprisal complaint under Ontario’s Occupational Health and Safety Act (OHSA). These complaints move fast and can carry serious consequences if mishandled. Knowing what counts as a reprisal — and how to respond — helps protect your business and keeps you compliant with Ontario law.
Under OHSA, workers have the right to speak up about safety without fear of discipline. When that line is crossed, even unintentionally, the Ministry of Labour or the Ontario Labour Relations Board (OLRB) can get involved.
An unjust reprisal happens when an employer penalizes a worker for exercising their health and safety rights. Section 50 of OHSA sets out these protections.
Common actions that may be considered a reprisal include:
Protected activities include:
The key issue is cause and effect. If the worker can show their protected activity was a factor in your decision, the burden shifts to you to prove otherwise.
Unjust reprisal complaints are usually handled by the Ontario Labour Relations Board (OLRB), not the Ministry inspector. Early steps matter.
Best practices once a complaint is raised:
Do not assume the complaint will be dismissed quickly. Even small businesses are expected to show clear, lawful reasoning.
Tools like GrantHub’s eligibility matcher can also help you identify advisory programs that support Ontario employers dealing with regulatory disputes.
Ontario employers do not have to handle reprisal complaints alone. The Ontario Office of the Employer Adviser (OEA) provides free, confidential advice and representation to eligible employers.
What the OEA helps with:
Who is eligible:
There is no funding cap or fee. All services are publicly funded and provided at no cost.
Disciplining too quickly
Acting before reviewing OHSA protections can strengthen a worker’s case.
Poor documentation
Verbal warnings without written records are hard to defend at the OLRB.
Treating safety complaints as insubordination
Safety concerns are legally protected, even if raised bluntly.
Ignoring early advice
Many cases escalate because employers wait too long to get guidance.
Q: What is an unjust reprisal under Ontario’s OHSA?
An unjust reprisal is any penalty or threat against a worker for exercising health and safety rights. This includes firing, discipline, or reduced hours linked to OHSA activity.
Q: Who investigates reprisal complaints in Ontario?
Most unjust reprisal complaints are decided by the Ontario Labour Relations Board. Ministry of Labour inspectors may still be involved in related safety issues.
Q: Do I need a lawyer for an OHSA reprisal complaint?
Not always. The Ontario Office of the Employer Adviser provides free representation and advice for eligible Ontario employers.
Q: Is advice from the Employer Adviser confidential?
Yes. Consultations with the OEA are confidential and designed to help employers understand their legal position.
Q: Can I discipline an employee after a safety complaint?
Yes, but only if you can clearly prove the discipline is unrelated to the protected activity. Strong documentation is critical.
Handling unjust reprisal complaints under Ontario’s OHSA requires speed, clarity, and the right support. Free public resources like the Ontario Office of the Employer Adviser can make a real difference when timelines are tight.
