How to Properly Complete a WSIB Worker’s Report of Injury (Form 6) in Ontario

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

In Ontario, you must file your WSIB Form 6 within six months of a workplace injury. Accurately describing the exact mechanism of your injury is critical, as vague descriptions are a leading cause of claim denials. Retaining a local WSIB lawyer early can help protect your benefits.

Suffering a workplace injury is a stressful and overwhelming experience. 🚨 However, securing your right to lost wages and medical coverage relies entirely on how quickly and accurately you report the incident. The Workplace Safety and Insurance Board (WSIB) uses the Worker’s Report of Injury/Disease (Form 6) as the foundational document for your claim in Ontario.

Many injured workers assume their employer or doctor will handle everything. 📝 While they submit their own forms (Form 7 and Form 8), your Form 6 is your only opportunity to tell your side of the story in your own words. Filling it out correctly prevents early denials, ensures prompt payment, and establishes a clear legal record if your claim requires an appeal later on.

Step-by-Step Guide to Completing WSIB Form 6 in Ontario

Whether you work in a warehouse in Brampton or an office in Kingston, the process of filing a Form 6 remains identical. 📂 The WSIB scrutinizes these forms closely for inconsistencies. By following a methodical approach, you can ensure your application clearly links your injury directly to your workplace duties.

Step 1: Seek Immediate Medical Attention

Your health is always the top priority. 👨 Go to a local hospital, urgent care clinic, or your family doctor immediately after the accident. Clearly inform the healthcare provider that this is a workplace injury so they can fill out a Form 8 (Health Professional’s Report) and send it directly to the WSIB.

Step 2: Notify Your Employer Promptly

You must inform your supervisor or human resources department about the injury as soon as possible. 📣 Delaying the report can make the WSIB suspicious about the legitimacy of your claim. Once notified, your employer is legally obligated to file a Form 7 (Employer’s Report of Injury/Disease) within three days of learning about the incident.

Step 3: Access and Start the Form 6

You can complete the Form 6 online via the WSIB portal, or download a printable PDF copy. 💻 The online method is highly recommended as it provides an immediate confirmation number and speeds up the processing time. Make sure you have your Social Insurance Number (SIN), employer details, and healthcare provider’s information handy before you begin.

Step 4: Describe the Accident Mechanism Accurately

This is the most critical section of the document. 🔍 You must describe exactly how the injury happened, not just what hurts. Instead of writing “I hurt my back,” write “I was lifting a 50-pound box from the floor to a shelf, twisted to my left, and felt a sharp pop in my lower back.” Precision eliminates ambiguity and strongly supports your entitlement to benefits.

Step 5: Review, Sign, and Submit

Carefully review the form to ensure dates, times, and body parts match what you told your doctor and employer. 📄 Sign the document and submit it directly to the WSIB. You must also provide a copy of the completed Form 6 to your employer so they are aware of the specifics of your claim.

Are There Costs to File a WSIB Form 6 in Ontario?

Filing the initial claim with the WSIB is completely free of charge. 💰 There are no application fees or court filing costs to submit a Form 6. However, if your claim is denied and you need to launch an appeal, there may be associated costs for gathering additional evidence.

  • Medical Records: Doctors may charge a fee ranging from $50 to $150 CAD to provide copies of your detailed clinical notes.
  • Specialist Reports: If you need an independent medical assessment to prove your case, experts can charge $1,500 to $3,500 CAD.
  • Lawyer Fees: Most WSIB law firms work on a contingency fee basis for appeals, taking between 15% and 30% of your retroactive lump-sum settlement if you win.

How Long Does the WSIB Claim Process Take?

Time limits are strictly enforced in WSIB matters. 🕙 You have exactly six months from the date of the accident (or the date you realized a disease was work-related) to file your Form 6. Once submitted online, the WSIB usually assigns a claim number within a few days. For straightforward injuries with matching employer and medical reports, initial benefit payments can start arriving within 2 to 4 weeks. Complex cases may take several months to adjudicate.

Frequently Asked Questions (FAQ)

What happens if I miss the 6-month deadline to file Form 6?

If you miss the deadline, your claim will likely be denied automatically. However, the WSIB may grant an extension in exceptional circumstances, such as severe medical incapacitation or employer interference.
Do I have to file a Form 6 if I didn’t miss any time off work?

Yes, it is highly recommended. Even if you only require medical treatment (like physiotherapy) and modified duties, filing establishes a record in case your injury worsens in the future.
What if my employer tells me not to file a WSIB claim?

It is illegal for an employer in Ontario to coerce an employee into not reporting a workplace injury. You should file your Form 6 immediately and report the employer’s behaviour to the WSIB.
Can a law firm fill out the Form 6 for me?

Yes, you can retain a local lawyer or paralegal to assist you from the very beginning. They can ensure the accident mechanics are drafted perfectly to avoid potential denials.
