In Ontario, workers have a legal right under the Occupational Health and Safety Act (OHSA) to refuse unsafe work. Employers must immediately initiate a mandatory two-stage investigation process. If internal resolution fails, the Ministry of Labour, Immigration, Training and Skills Development (MLITSD) must be called. Ignoring this duty can result in corporate prosecution fines of up to $2,000,000 CAD or direct administrative monetary penalties (AMPs) under new 2026 enforcement regulations.
Workplace safety is the cornerstone of any thriving business in Canada. Whether your operations are based in a busy manufacturing plant in Toronto, a construction site in Mississauga, or a logistics hub in Ottawa, understanding how to handle a work refusal is critical. The process is strictly governed by Ontario law to ensure that workers are protected from imminent hazards while maintaining operational fairness.
When an employee halts production citing unsafe conditions, it can be a stressful moment for site supervisors and HR managers. However, it is essential to remain calm and follow the legal framework. ⚠ Generally, this is not a time for disciplinary action; it is a time for immediate investigation. Retaliating against a worker for exercising their OHSA rights is considered an offence and can lead to severe legal repercussions for both the company and the individual supervisor.
By understanding the precise steps required by the provincial government, you can resolve the situation efficiently. This guide provides a straightforward, step-by-step approach to managing a refusal to work in Ontario, helping you maintain compliance and safeguard your workforce.
Step-by-Step Work Refusal Process in Ontario
Ontario’s Occupational Health and Safety Act outlines a highly specific, mandatory two-stage process when an employee refuses work. Whether your business is in Hamilton, London, or Sudbury, these rules apply uniformly across the province. 🔍 It is highly advisable to have your Joint Health and Safety Committee (JHSC) members trained on these exact procedures.
Step 1: The Initial Refusal and Safe Relocation
The moment an employee reports that their work, tools, or environment is likely to endanger them, the work refusal process officially begins. The worker must immediately inform their supervisor or employer about the exact nature of the hazard. You cannot force them to return to the specific task while the danger is being assessed.
As a supervisor, your first legal duty is to ensure the refusing worker is moved to a safe location nearby. 🚩 They must remain available for the investigation, and you must continue to pay them their regular wages during this time. Do not attempt to assign the dangerous task to another worker unless you explicitly inform that second worker of the ongoing refusal and the reasons behind it, usually in the presence of a JHSC member.
Step 2: The First Stage Internal Investigation
Once the worker is safe, the first stage of the investigation must commence immediately. This internal review requires the supervisor to investigate the hazard in the presence of the refusing worker and a worker representative, which is typically a member of your company’s Joint Health and Safety Committee (JHSC) or a union representative.
During this stage, all parties examine the equipment or environment in question. 💬 If the supervisor agrees that a hazard exists, the company must take immediate steps to correct it. Once fixed, the worker is generally expected to return to work. However, if the supervisor believes the area is safe but the worker continues to feel endangered, the process escalates to the second stage.
Step 3: The Second Stage Investigation (Calling MLITSD)
If the internal investigation fails to resolve the dispute, the employer, worker, or representative must immediately contact the Ministry of Labour, Immigration, Training and Skills Development (MLITSD). At this point, the situation is out of the company’s direct control, and a provincial inspector will be dispatched to your Ontario workplace.
While waiting for the MLITSD inspector to arrive, the refusing worker must remain in a safe location during their normal working hours. ⌛ You may assign them reasonable alternative duties that do not conflict with their collective agreement or employment contract. The inspector will conduct a neutral, independent investigation of the hazard.
Step 4: The MLITSD Inspector’s Decision
The provincial inspector will arrive and assess the situation alongside the supervisor, the worker, and the JHSC representative. After a thorough review, the inspector will issue a written decision outlining whether the work is likely to endanger the worker.
If the inspector finds a hazard, they will issue binding orders to the employer to correct the issue before work can resume. 📋 If the inspector declares the work environment safe, the worker is legally required to return to their duties. Failure to return to work after an inspector deems it safe may become a disciplinary matter, though consulting a local employment lawyer before taking action is strongly recommended.
How Much Are the Fines and Penalties in Ontario?
Failing to comply with OHSA regulations during a work refusal can result in massive financial penalties. It is generally more cost-effective to pause production and fix a safety issue than to face a provincial prosecution. Under the Working for Workers Act, 2023, the maximum corporate fine is $2,000,000 CAD per offence.
Furthermore, as of January 1, 2026, under the Working for Workers Seven Act, 2025 (Bill 30) and Ontario Regulation 365/25, Ministry of Labour inspectors have the power to issue direct Administrative Monetary Penalties (AMPs) for health and safety infractions. This administrative, non-court process allows inspectors to impose swift financial sanctions on employers without initiating formal court prosecutions. Below are the current maximum court prosecution penalties under Ontario law:
| Entity Type | Maximum OHSA Fine (CAD) | Potential Imprisonment |
|---|---|---|
| Corporation | Up to $2,000,000 | N/A |
| Corporate Directors / Officers | Up to $1,500,000 | Up to 12 months |
| Individual Supervisors / Workers | Up to $500,000 | Up to 12 months |
Beyond government fines, businesses may also incur legal fees if they need to hire a law firm to defend against an OHSA prosecution. 💵 Corporate defence lawyers in Ontario typically charge between $350 and $800 CAD per hour depending on their experience and the complexity of the trial.
How Long Does the Process Take?
The OHSA requires the initial stage of the investigation to happen immediately. You cannot delay the internal review until the next shift or the following business day. The safety of the workplace must be assessed right away.
If the dispute escalates to the MLITSD, wait times for an inspector can vary. 🚗 In major centres like Toronto or Mississauga, an inspector may arrive within a few hours. In more remote regions of Northern Ontario, it may take longer, or the initial consultation might occur over the phone. A full written decision is usually provided on the same day the inspection takes place.
Frequently Asked Questions (FAQ)
Can I fire an employee for refusing unsafe work?
No. Under Section 50 of the OHSA, employers are strictly prohibited from dismissing, disciplining, or suspending a worker for complying with the Act or seeking its enforcement. This is known as a reprisal, and the Ontario Labour Relations Board takes these complaints very seriously.
Do I have to pay the worker while they refuse to work?
Yes. The refusing worker is deemed to be at work during the first and second stages of the investigation. You must pay them their regular hourly rate or salary while they wait in a safe location or perform alternative assigned duties.
Can a worker refuse work because of workplace harassment?
Yes, but with limitations. Ontario law recognizes workplace violence as a valid reason to refuse work if it is likely to endanger the worker. However, general workplace harassment (without the threat of physical violence) typically requires a different reporting process under the employer’s workplace harassment policy, rather than an immediate work refusal.
Do certain professions not have the right to refuse work?
Yes. Police officers, firefighters, and certain healthcare workers (such as those in hospitals or long-term care homes) have a limited right to refuse work. They cannot refuse work if the hazard is a normal condition of their employment or if their refusal would directly endanger the life, health, or safety of another person.
Should I contact a law firm during a Ministry inspection?
While not strictly legally required, it is highly advisable. If a severe hazard or critical injury is involved, consulting an Ontario employment lawyer or OHSA defence lawyer can help you navigate the inspector’s questions and ensure your corporate rights are protected during the investigation.
