Can You Claim WSIB If You Were Fired Shortly After Reporting an Injury in Ontario?

15 Jun 2026 4 min read No comments WSIB Claims & Workplace Injuries Ontario
💡

If your employer fires you within six months of reporting a workplace injury in Ontario, the Workplace Safety and Insurance Act (WSIA) automatically presumes this is an illegal reprisal. You have the right to file a complaint to seek lost wages or reinstatement, and there are absolutely zero filing fees to start this process.

Being injured on the job is already a difficult experience, but losing your livelihood shortly after reporting that injury can feel devastating 😢. Many workers in Ontario worry that speaking up about an unsafe work environment or a recent physical trauma will cost them their job. Fortunately, the province has strict rules to protect employees. If you are terminated, laid off, or disciplined soon after reporting an injury, the law is designed to shield you from unjust punishment.

In Ontario, the Workplace Safety and Insurance Board (WSIB) strongly enforces anti-reprisal laws. Whether you work in a busy Toronto warehouse, an Ottawa office building, or a Mississauga construction site, your employer cannot legally fire you simply because you filed a WSIB claim. We will walk you through exactly what your rights are, how the six-month presumption rule works, and the steps you need to take to protect your income and career .

Step-by-Step Process for Reprisal Claims in Ontario

Filing a reprisal complaint requires acting quickly and keeping detailed records. The process generally involves both the WSIB and the Ontario Labour Relations Board (OLRB). Whether you live in Hamilton, Brampton, or Sudbury, these provincial steps remain the same.

Step 1: Gather Your Documentation

Before making a formal complaint, you need evidence. Even though the law is on your side, having a clear paper trail is vital 📋. You should collect your official termination letter, any emails or text messages leading up to your dismissal, and a copy of the Form 6 (Worker’s Report of Injury) that you submitted. Note the exact date you reported your injury and the exact date you were fired. If these two dates are within six months of each other, you have a strong starting point.

Step 2: Notify the WSIB Immediately

You must inform your WSIB case manager that you have been terminated. Do not assume they already know. Call them or send a message through the online WSIB portal. Informing the WSIB ensures that your Loss of Earnings (LOE) benefits are accurately calculated, as your employer is no longer paying your regular wages. The WSIB will also document the termination in your official file, which is an essential piece of the puzzle .

Step 3: File a Reprisal Complaint with the OLRB

To officially challenge the termination, you or your chosen legal representative must file an application with the Ontario Labour Relations Board. You must complete and submit Form A-53 (Application under Section 133 of the WSIA). The OLRB will then assign a Labour Relations Officer to help you and your employer reach a settlement through mediation. If no agreement is reached, a formal hearing will be scheduled where an adjudicator will make a final, binding decision.

How Much Does it Cost to Challenge a Reprisal in Ontario?

Understanding the costs involved can help ease the financial stress of losing your job 💵.

Service / Fee TypeEstimated Cost (CAD)
WSIB Filing Fee$0 (It is completely free to file WSIB forms).
OLRB Application Fee$0 (There is no government fee to file a reprisal application).
Lawyer / Paralegal FeesOften handled on a contingency basis (percentage of settlement) or hourly ($250 – $600/hr).
Medical Documentation$50 – $150 (If you need extra doctor’s notes, though WSIB often covers direct medical reports).

Because the legal system can be complex, most applicants in this province choose to hire a knowledgeable workers’ compensation lawyer or paralegal. A legal professional can ensure your Form A-53 is filled out perfectly and represent you during OLRB mediation.

How Long Does the Process Take?

Timeframes can vary depending on how strongly your employer fights the claim. Generally, informing the WSIB and submitting your OLRB application takes only a few days. However, waiting for mediation with the OLRB typically takes 4 to 8 weeks. If mediation fails and you must proceed to a formal hearing, the entire process can take anywhere from 6 to 12 months before a final decision is rendered .

Frequently Asked Questions (FAQ)

What exactly is the six-month presumption rule?

Under the WSIA, if your employer terminates you within six months of you reporting a workplace injury, the law presumes they fired you because of the injury. The burden of proof shifts to the employer to prove they had a legitimate, unrelated reason for the termination.

What if my employer says they fired me for poor performance?

Employers often claim a termination was for cause or poor performance. However, because of the six-month rule, they must provide overwhelming, documented evidence that your performance was an issue before the injury occurred. If they cannot prove this, the OLRB will likely rule in your favour.

Can I receive Employment Insurance (EI) while fighting my case?

You may be entitled to standard Service Canada EI benefits if you were terminated, provided you are capable of working modified duties. However, if you are completely unable to work due to your injury, you should be receiving WSIB Loss of Earnings (LOE) benefits instead.

Do I have to go back to work for them if I win?

Not necessarily. While reinstatement (getting your job back) is a common remedy, many workers prefer to seek a financial settlement for lost wages and damages rather than returning to a toxic work environment. You and your lawyer can negotiate what is best for your situation.

Can a temporary or probationary worker claim reprisal?

Yes! The WSIA protects all covered workers in Ontario, including those on probation, part-time staff, and temporary workers. You still have the right to a safe workplace and protection from illegal termination.
