How to File a WSIB Claim in Ontario: Step-by-Step Guide

Getting hurt at work is stressful enough without the added confusion of paperwork and deadlines. If you have been injured on the job in Ontario, you have the right to file a claim with the Workplace Safety and Insurance Board (WSIB) for income replacement, medical coverage, and return-to-work support. The process is straightforward when you know the steps, and this guide walks you through each one.

What Is a WSIB Claim and Who Can File One?

A WSIB claim is a formal request for benefits after a workplace injury or illness in Ontario. The WSIB is a provincial agency that provides no-fault insurance to workers, meaning you do not need to prove your employer was at fault to receive benefits. You file a claim by submitting a Worker's Report of Injury/Disease (Form 6) to the WSIB. For a broader look at how this system protects you, see our guide to your workers' compensation rights in Ontario.

You can file a WSIB claim if you meet these conditions:

• You were injured in an accident at work (for example, a fall, a cut, or sudden back pain from lifting)
• You developed a medical condition caused by your work (for example, carpal tunnel syndrome from repetitive tasks)
• You developed an occupational disease linked to workplace exposure (for example, hearing loss from prolonged noise exposure)

Most workers in Ontario are covered by WSIB through their employer. This includes full-time, part-time, seasonal, and temporary workers. Independent contractors and self-employed individuals are generally not covered unless they have opted in.

According to WSIB data, Ontario sees over 236,000 workplace injuries each year, with approximately 48,700 registered claims in a single quarter (WSIB Open Data, Q3 2025). You are not alone in this process, and the system exists specifically to help you.

Step 1: Report Your Injury to Your Employer

The first thing you need to do after a workplace injury is tell your employer. Report the injury as soon as possible, even if it seems minor at first. Delays in reporting can create problems for your claim later.

When you report your injury:

• Tell your supervisor or manager directly. Note the date, time, and the name of the person you reported to.
• Get medical attention. Visit your doctor, a walk-in clinic, or an emergency room. Tell the health professional that your injury is work-related so they can complete the appropriate forms.
• Document everything. Write down what happened, when it happened, where it happened, and who witnessed it. Take photos of the injury or the hazard if you can.

Your employer has their own reporting obligation. Under the Workplace Safety and Insurance Act, employers must submit an Employer's Report of Injury/Disease (Form 7) to the WSIB within three business days of learning about your injury. If your employer is late, the WSIB can charge them a $250 penalty for reports filed after three business days, or $1,000 for reports filed more than 30 calendar days late (WSIB, Form 7 Reference Guide).

Your employer is also required to give you a copy of their completed Form 7. If they do not, ask for it. You have the right to see what they reported. Employers also have obligations around WSIB accommodation rights, including helping with your return to work.

Step 2: Complete and Submit WSIB Form 6

Form 6, the Worker's Report of Injury/Disease, is the form you fill out to make your claim. It is separate from whatever your employer submits. Your employer files Form 7; you file Form 6. Both reports matter, and having your own account on file protects your interests.

Here is what Form 6 asks for:

• Section A: Your personal details (name, address, date of birth, job title, employer name)
• Section B: Your employer's information (company name, address, supervisor's name)
• Section C: Accident or illness details (date, time, location, body parts affected, description of what happened)
• Section D: Health care information (your doctor or health professional's details)
• Section G: Your declaration and signature confirming everything is accurate

How to submit Form 6:

1. Online: Log in to the WSIB's secure online services at wsib.ca and submit the form digitally. This is the fastest option.
2. PDF: Download the Form 6 PDF from the WSIB website, fill it out, and submit it at wsib.ca/submit.
3. By mail: Send the completed form to WSIB at 200 Front Street West, Toronto, Ontario, M5V 3J1.
4. By phone: Call the WSIB at 1-800-387-0750 (Monday to Friday, 7:30 a.m. to 5 p.m.) if you need help filling out the form.

After you submit Form 6, give a copy to your employer and keep a copy for your own records. The WSIB will assign a claim number and send it to you once your claim is registered.

Find a WSIB paralegal in Ontario who can review your Form 6 before you submit it.

Step 3: What Happens After You File

Once the WSIB receives your Form 6 (and your employer's Form 7), a case manager will be assigned to review your claim. Here is the general process:

1. Claim registration: The WSIB logs your claim and assigns a claim number. You will receive this by mail.
2. Initial review: Your case manager reviews the information from both forms, along with any medical reports from your health care provider.
3. Decision: The WSIB decides whether to allow or deny your claim based on the evidence. They look at whether the injury is work-related, whether you reported it on time, and whether the medical evidence supports your claim.
4. Benefits begin: If your claim is allowed, benefits can include loss-of-earnings payments (85% of your pre-injury net earnings), health care coverage, and return-to-work assistance.

During the review, your case manager may contact you, your employer, or your health care provider for more information. Respond to requests quickly to avoid delays. If your claim involves a loss-of-earnings dispute down the road, you can learn more about how to dispute WSIB LOE benefits.

How Long Does a WSIB Claim Take to Process?

There is no single answer because every claim is different. Simple claims with clear evidence (for example, a witnessed fall with immediate medical treatment) can be processed in a few weeks. More complex claims involving occupational diseases or disputed circumstances can take several months.

Several factors affect processing time:

• Completeness of your forms: Missing information on Form 6 or Form 7 causes delays. Double-check every section before submitting.
• Medical evidence: The sooner your health care provider submits their report, the sooner the WSIB can make a decision.
• Employer cooperation: If your employer disputes the claim or submits Form 7 late, it can slow things down.
• Complexity of the injury: Repetitive strain injuries, occupational diseases, and mental health claims often require more investigation.

The key deadline to remember: you have six months from the date of your injury or illness to file your claim with the WSIB (Workplace Safety and Insurance Act, s. 22). Filing sooner is always better. Claims filed months after an injury face more scrutiny and are harder to support with evidence.

Common Mistakes That Get WSIB Claims Denied

Roughly 17,500 to 18,750 WSIB claims are denied each year in Ontario (WSIB Open Data). Many of these denials are avoidable. For a deeper look at denial patterns, read our article on the top reasons WSIB claims get denied. Here are the most common mistakes workers make when filing:

1. Waiting too long to report. The longer you wait to tell your employer and file Form 6, the weaker your claim looks. Report the injury the same day if possible.
2. Incomplete forms. Leaving sections blank or providing vague descriptions gives the WSIB less to work with. Be specific about what happened, when, and where.
3. Inconsistent accounts. If your Form 6, your employer's Form 7, and your medical records tell different stories, the WSIB may question the claim. Make sure your description of the accident is consistent across all documents.
4. Not seeking medical attention promptly. Seeing a doctor days or weeks after the injury raises doubts about whether the injury is work-related. Get medical care right away.
5. Not mentioning prior injuries. Form 6 asks whether you have hurt the same body area before. Be honest. The WSIB will check, and withholding information can hurt your credibility.
6. Ignoring follow-up requests. If your case manager asks for additional information or documentation, respond promptly. Silence can lead to a denial based on insufficient evidence.

When Should You Get Legal Help With Your WSIB Claim?

Many straightforward claims go through without any legal help. But certain situations make professional representation worth considering:

• Your claim was denied and you need to understand the WSIB appeal process
• Your employer is disputing whether the injury is work-related
• You have a pre-existing condition that complicates the claim
• Your injury is complex (occupational disease, repetitive strain, mental health)
• You are not receiving the benefits you expected or your benefits were reduced
• You need to appeal to the Workplace Safety and Insurance Appeals Tribunal (WSIAT)

WSIB lawyers and paralegals in Ontario typically work on a contingency fee basis, meaning you do not pay upfront. To understand what that costs in practice, see our breakdown of how much a WSIB lawyer costs. The standard contingency fee is around 30% of any benefits recovered.

FAQ: Filing a WSIB Claim in Ontario

Can I file a WSIB claim if my employer did not report the injury?

Yes. Your right to file a claim does not depend on your employer filing Form 7. You can submit your own Form 6 directly to the WSIB. Your employer may face penalties for failing to report, but that does not affect your eligibility for benefits.

What if my injury happened outside Ontario?

If you are an Ontario worker injured in another province or country, you may have the option to file your claim in Ontario or in the jurisdiction where the injury occurred. The WSIB will send you an election form so you can choose. You have three months from the date the WSIB sends the form to make your choice.

Do I need a lawyer to file a WSIB claim?

No. Most initial WSIB claims can be filed without a lawyer. The process is designed for workers to handle on their own. However, if your claim is denied, disputed by your employer, or involves complex medical issues, working with a WSIB paralegal or lawyer can improve your chances of a successful outcome.

What benefits can I receive from a WSIB claim?

WSIB benefits can include loss-of-earnings payments (85% of your pre-injury net earnings, up to a maximum), full coverage for medical treatment related to your injury, prescription medication, assistive devices, and return-to-work support programs. You may also be eligible for a Non-Economic Loss (NEL) assessment if your injury causes permanent impairment. The specific benefits depend on your injury and circumstances.

Can I be fired for filing a WSIB claim?

No. Ontario law prohibits employers from firing, penalizing, or discriminating against a worker for filing a WSIB claim. If your employer retaliates against you for making a claim, you can file a complaint with the Ontario Ministry of Labour. This protection applies even if your claim is ultimately denied.

What happens if my WSIB claim is denied?

If your claim is denied, you have the right to appeal. The first step is an internal review called a "reconsideration" or "objection." If that does not resolve the issue, you can appeal to the Workplace Safety and Insurance Appeals Tribunal (WSIAT). The appeal process has strict deadlines, so acting quickly is important.
