How to File a WSIB Claim in Ontario (2026 Guide)

Over 200,000 workplace injuries are reported to WSIB each year. If you've just been hurt at work, you're not alone—and you have rights.

Filing a WSIB claim correctly from the start can mean the difference between receiving full benefits and facing delays or denials. Many workers make simple mistakes that cost them weeks of lost income.

This guide gives you the exact steps to file your claim properly, avoid common pitfalls, and protect your right to benefits. By the end, you'll know exactly what to do, when to do it, and what documents you need.

Who Can File a WSIB Claim?

Most workers in Ontario are covered by WSIB, including:

• Full-time and part-time employees
• Temporary and contract workers (in most cases)
• Some independent contractors (depending on the work arrangement)

If you're unsure whether you're covered, ask your employer or contact WSIB directly.

Step 1: Report Your Injury to Your Employer

Timeline: As soon as possible after the injury occurs.

Your first step is to notify your employer about the injury. This can be verbal or written, but we recommend putting it in writing (email or letter) so you have a record.

Your employer is legally required to:

• Provide first aid if needed
• Report the injury to WSIB if you need medical attention beyond first aid or miss time from work
• Not discourage you from filing a claim

Step 2: Get Medical Attention

See a doctor or healthcare provider as soon as possible. Be sure to:

• Describe exactly how the injury happened at work
• Explain all symptoms, even if they seem minor
• Ask for copies of any medical reports

Your healthcare provider will complete a Physician's Report (Form 8) and submit it to WSIB. This form is critical—it establishes the medical basis for your claim.

Step 3: Complete Your Worker's Report (Form 6)

Deadline: You should file within 6 months of the injury, but sooner is better.

Form 6 is your official claim to WSIB. You can:

• Complete it online through WSIB's portal
• Download a PDF and mail it
• Use ClaimNexus to help organize your information before submitting

What to Include on Form 6

• Your personal information (name, address, date of birth)
• Employer details
• Date, time, and location of the injury
• How the injury happened (be specific)
• What body parts were injured
• Whether you missed work

Tip: Be detailed and accurate. Vague descriptions can delay your claim.

Step 4: Employer Submits Form 7

Your employer must submit a Form 7 (Employer's Report of Injury) to WSIB within 3 business days of learning about an injury that requires medical attention or causes you to miss work.

If your employer hasn't submitted Form 7, your claim can still proceed—but it may take longer.

Key Deadlines to Remember

What Happens After You File

1. WSIB reviews your claim – They'll contact you if they need more information
2. Initial decision – WSIB will approve or deny your claim (typically within 2-4 weeks)
3. Benefits begin – If approved, you'll start receiving Loss of Earnings (LOE) benefits
4. Ongoing requirements – You may need to provide updates, attend appointments, or participate in return-to-work planning

Common Mistakes to Avoid

• Waiting too long to report – File as soon as possible
• Being vague about the injury – Provide specific details
• Not keeping copies – Save all documents, emails, and forms
• Ignoring deadlines – Missing deadlines can affect your benefits
