Appealing a Ministry of Labour Inspector’s Decision in Ontario

9 Jun 2026 5 min read No comments Work & Employment Rights Ontario
⚠️

If you disagree with a Ministry of Labour inspector’s health and safety order (or their refusal to issue one), you have a strict 30-day deadline to file an appeal with the Ontario Labour Relations Board (OLRB). You must submit a Form A-65 Appeal Application to formally challenge the decision.

When a Ministry of Labour, Immigration, Training and Skills Development (MLITSD) inspector visits your workplace, their decisions carry the full weight of the law. For an employer, a strict compliance order or a “Stop Work Order” can halt production and cost thousands of dollars a day. For a worker, an inspector deciding that a dangerous task is “safe” can feel like a devastating blow to your personal security.

However, an inspector’s word is not the absolute final authority in Ontario. Whether your business is located in Hamilton, London, or Vaughan, the Occupational Health and Safety Act (OHSA) provides a formal mechanism to challenge these decisions. 📈 The Ontario Labour Relations Board (OLRB) acts as the independent tribunal that reviews Ministry orders. Because OLRB hearings function like miniature court trials, complete with witnesses and cross-examinations, attempting this without professional representation is highly risky. Consulting an experienced employment and labour lawyer from our directory is critical to building a winning appeal.

Step-by-Step Process for Appealing an OHSA Decision

Appealing an inspector’s decision is not as simple as calling their supervisor and complaining. The OLRB relies on a highly structured, legalistic procedure. Missing a single form or deadline can result in your appeal being dismissed immediately. Here is the path you must follow.

Step 1: Mark the 30-Day Deadline

The most important rule in an OLRB appeal is the timeline. 📅 Under Section 61 of the OHSA, any aggrieved party (employer, worker, or trade union) has exactly 30 calendar days from the date the inspector issued their written field report to file an appeal. If you file on day 31, the Board will almost certainly reject your application.

Step 2: Complete Form A-65 (Appeal of Inspector’s Order)

To initiate the appeal, your lawyer will draft and complete Form A-65. This is a detailed legal document where you must explain exactly which order you are appealing, the factual background of the workplace hazard, and why you believe the inspector was legally incorrect in their assessment. You must also attach a copy of the inspector’s original field report.

Step 3: Request a Suspension of the Order (Optional)

Filing an appeal does not automatically pause the inspector’s order. 🚨 If you are an employer facing a crippling Stop Work Order, you must comply with it while waiting for your hearing. However, your lawyer can file a separate application (Form A-66) asking the OLRB to formally “suspend” the order pending the appeal. The Board will only grant this if you can prove that suspending the order will not endanger worker safety.

Step 4: Serve the Documents on All Parties

Before you can file your appeal with the OLRB, you must deliver a copy of your Form A-65 to every affected party. This includes the specific MLITSD inspector, the Director of the Ministry, the Joint Health and Safety Committee (JHSC), and any affected trade union. Once everyone is served, you file the proof of service and the application with the Board in Toronto.

Step 5: Attend Mediation and the Formal Hearing

Once the OLRB processes the appeal, they will assign a Labour Relations Officer (LRO) to your case. 🤝 The LRO will attempt to mediate a settlement between you, the Ministry, and the union without going to trial. If mediation fails, a formal hearing is scheduled before an OLRB Vice-Chair. Your lawyer will present evidence, call expert witnesses, and argue why the inspector’s order should be rescinded or changed.

How Much Does an OLRB Appeal Cost?

Fighting the provincial government requires a serious financial commitment. 💲 While the OLRB tries to be accessible, the complexity of OHSA laws means that legal and expert fees are virtually unavoidable for employers. Here is a breakdown of estimated costs in CAD:

Service / ExpenseEstimated Cost (CAD)Details
OLRB Filing Fee$0The Ontario government does not charge a filing fee to submit an OHSA appeal.
Initial Lawyer Retainer$3,500 – $7,500Standard deposit for a labour firm to analyze the order and draft Form A-65.
Expert Witness Fees$2,000 – $10,000+Hiring a private safety engineer to testify that your machines are actually safe.
Full Board Hearing$15,000 – $30,000+Extensive legal fees if the case requires multiple days of litigation at the OLRB.

How Long Does the Appeal Process Take?

The OLRB recognizes that workplace safety matters are urgent, but the justice system moves at its own pace. If you file an urgent request to suspend a Stop Work Order, the Board may hear that preliminary motion within 1 to 3 weeks.

However, the actual appeal of the decision itself takes much longer. Mediation meetings typically occur within 2 to 4 months of filing. If the matter cannot be settled and must proceed to a full contested hearing before a Vice-Chair, you can expect the entire process to take anywhere from 6 to 12 months before a final ruling is published.

Frequently Asked Questions (FAQ)

Can an employee appeal if the inspector didn’t issue an order?

Yes. If a worker reports a hazard and the Ministry inspector concludes that there is no OHSA violation, the worker or their union can appeal the inspector’s decision not to issue an order to the OLRB.

Does appealing stop the Ministry from prosecuting me?

No. Appealing an inspector’s order to the OLRB is an administrative process. It does not prevent the Ministry of Labour from deciding to separately lay quasi-criminal charges against the corporation in Provincial Offences Court for the original safety violation.

Can the OLRB increase the severity of the inspector’s order?

Yes. The OLRB has incredibly broad powers. Under the OHSA, the Board can confirm, vary, revoke, or substitute the inspector’s decision. This means they could theoretically impose a stricter order on the employer than the inspector originally did.

Do I have to hire a lawyer for an OLRB hearing?

You are not legally required to have a lawyer, but it is extremely dangerous for an employer to represent themselves. The OLRB operates with strict rules of evidence and cross-examination. Facing Ministry of Labour lawyers without your own counsel is a massive disadvantage.

What happens if I ignore the order while waiting for my appeal?

Unless the OLRB has officially granted a formal “Suspension of Order,” ignoring the inspector’s demands is a direct violation of the OHSA. You can face immediate prosecution, massive administrative fines, and severe legal liability if a worker gets injured in the meantime.
