In Ontario, the Ministry of Labour, Immigration, Training and Skills Development (MLITSD) responds to critical injuries and formal work refusals almost immediately, often sending an inspector within a few hours. For standard, non-emergency health and safety complaints, an investigation generally begins within 1 to 3 weeks. Filing a complaint is completely free, and it is illegal for your employer to punish you for reporting a hazard.
Every worker in Ontario has the fundamental legal right to return home safely at the end of their shift. Whether you are pouring concrete on a high-rise construction site in downtown Toronto, operating heavy machinery in a Hamilton manufacturing plant, or sitting at a desk in an Ottawa corporate office, workplace hazards are a serious matter. The Occupational Health and Safety Act (OHSA) provides strict guidelines that all employers must follow to protect their staff. However, when an employer ignores safety protocols, workers often have no choice but to escalate the issue to the provincial government for an official intervention.
Understanding the exact timeline of a government investigation can help alleviate the intense stress of reporting your boss. 📍 The Ministry of Labour, Immigration, Training and Skills Development (MLITSD) categorizes complaints based on immediate danger. While a massive chemical spill or a worker falling from a scaffold will trigger an immediate emergency response, complaints about poor office ventilation, missing safety guards on older machines, or inadequate safety training might sit in a queue. In this comprehensive guide, we will walk you through the step-by-step process of filing a health and safety complaint in Ontario and explain exactly what to expect from the provincial inspectors.
Step-by-Step Process for OHSA Complaints in Ontario
Reporting a health and safety violation is a legally protected act, but it requires following a specific procedural chain of command. The Ministry generally expects you to try and resolve the issue internally first, unless there is an immediate, life-threatening danger. Here are the precise steps you should take to protect yourself and your coworkers.
Step 1: Report the Hazard Internally
Before calling the government, you are legally required under the OHSA to report the specific safety hazard to your direct supervisor or employer. 🔍 You should also immediately notify your workplace Health and Safety Representative or the Joint Health and Safety Committee (JHSC). Send a professional, written email or text message so that you have a verifiable paper trail showing exactly when you raised the concern. Most responsible employers will immediately fix the issue once it is formally brought to their attention in writing.
Step 2: Initiate a Formal Work Refusal
If your boss completely ignores your warning and orders you to perform a task that you genuinely believe will endanger your life or the health of a coworker, you have the legal right to initiate a formal “Work Refusal.” You must explicitly tell your supervisor, “I am refusing to work because I believe this situation is unsafe.” At this point, the employer must stop the work and investigate the hazard in the presence of your JHSC representative. You must remain in a safe place near your workstation while they investigate.
Step 3: Call the Ministry of Labour (MLITSD)
If the internal investigation finishes but you still reasonably believe the danger exists, the employer or the worker must contact the MLITSD immediately. ☎️ You can call the Health and Safety Contact Centre toll-free at 1-877-202-0008. If you are not refusing work but simply want to report an ongoing, non-emergency violation (like blocked fire exits or lack of safety training), you can also submit a complaint through the Ministry’s online portal or over the phone. You can request to remain completely anonymous when filing a general complaint.
Step 4: The Inspector’s Visit and Investigation
Once dispatched, a provincial health and safety inspector will arrive at your workplace. During a formal work refusal, the inspector will interview you, your supervisor, and the safety representative. The inspector has massive legal authority: they can issue compliance orders forcing the company to buy new safety gear, or they can issue a “Stop Work Order,” which legally shuts down a specific machine or the entire job site until the danger is permanently fixed. The inspector will provide a written report of their decision.
Step 5: File a Reprisal Claim if Punished
Unfortunately, some toxic employers will try to retaliate by firing you, cutting your shifts, or demoting you after you call the Ministry. ⚖️ This is known as an illegal “reprisal” under Section 50 of the OHSA. If this happens, you do not go back to the MLITSD; instead, you must file an urgent legal application with the Ontario Labour Relations Board (OLRB). An employment lawyer can help you file this claim to demand immediate reinstatement to your job, as well as significant financial damages for lost wages.
How Much Does it Cost in Ontario?
Ensuring your workplace is safe should never cost you money. The province of Ontario fully funds the health and safety enforcement system. However, if you are illegally fired and need to fight back, you might encounter some legal expenses. Here is the breakdown as of May 2026:
- Ministry of Labour Investigation: $0 CAD. Calling the MLITSD and having an inspector visit your workplace is a completely free public service.
- Filing an OLRB Reprisal Claim: $0 CAD. Submitting the formal paperwork to the Ontario Labour Relations Board is free of charge.
- Employment Lawyer Consultation: If you are fired and need a lawyer to review your reprisal case, expect to pay a one-time consultation fee of $150 to $350 CAD.
- Legal Representation at OLRB: Many specialized employment law firms will take a strong OHSA reprisal case on a contingency fee basis, meaning they only take a percentage (usually 25% to 35%) if you win a settlement.
| Action | Estimated Cost (CAD) | Who Handles It |
|---|---|---|
| Safety Complaint/Inspection | Free | MLITSD Inspectors |
| Reprisal Claim Filing | Free | Ontario Labour Relations Board |
| Private Legal Counsel | Hourly or Contingency | Employment Law Firm |
How Long Does the Process Take?
The timeline depends entirely on the immediate severity of the danger. ⏱ If you initiate a formal work refusal or report a critical injury, the Ministry considers this a “Code Red” emergency. An inspector will typically contact the workplace within 1 to 4 hours and usually arrives on-site the exact same day. Work cannot resume on that specific task until the inspector makes a legal ruling.
If you file a general, non-emergency complaint (for example, reporting that the warehouse is too hot in the summer or lacks proper signage), the Ministry will place it in a queue. It generally takes 1 to 3 weeks for an inspector to conduct a surprise audit. If you are illegally fired and file a reprisal claim with the OLRB, reaching a final hearing or settlement mediation can take 6 to 12 months, though urgent interim reinstatement orders can sometimes be secured in just a few weeks.
Frequently Asked Questions (FAQ)
Do I get paid while refusing unsafe work?
Yes. Under the OHSA, you must be paid your regular wages during the first stage of a work refusal and while the Ministry inspector is actively investigating. The employer can assign you reasonable alternative work during this waiting period.
Can I remain completely anonymous when calling the Ministry?
Yes. If you are calling to report a general safety violation, you can explicitly ask the MLITSD to keep your identity confidential. The inspector will conduct a “routine” surprise visit without telling the employer who made the initial complaint.
What happens if the inspector says the work is actually safe?
If the provincial inspector officially rules that the work process is safe and does not violate the OHSA, the legal work refusal ends. You are generally expected to return to work. Refusing to work after an inspector clears it could lead to lawful disciplinary action.
Does a work refusal apply to teachers or police officers?
Certain specific professions, such as police officers, firefighters, and healthcare workers, have strictly limited rights to refuse work if the danger is considered an inherent, normal part of their job, or if refusing the work would directly endanger the life of the public.
Can the Ministry force my employer to pay me severance?
No. MLITSD health and safety inspectors only deal with physical safety rules. If you are seeking financial compensation, lost wages, or severance pay due to an illegal reprisal termination, you must file that specific claim through the OLRB or civil court.
