WSIB Form 6: Complete Guide to the Worker's Report of Injury (2026)

Form 6 is your official claim to WSIB. Getting it right the first time can mean the difference between immediate benefits and weeks of delays.

This guide walks you through every section of Form 6, explains what WSIB is looking for, and shows you how to avoid the mistakes that delay or deny claims.

What is WSIB Form 6?

Form 6 (Worker's Report of Injury/Disease) is the document you submit to WSIB to officially report your workplace injury and request benefits.

Your Form 6:

• Starts your claim process
• Establishes when and how you were injured
• Triggers WSIB's investigation
• Determines your eligibility for benefits

When Must You File Form 6?

Deadline: Within 6 months of the injury

Best practice: File as soon as possible, ideally within 1-2 weeks

Filing quickly:

• Gets benefits flowing faster
• Shows the injury is serious
• Makes it easier to remember details
• Reduces the risk of claim denial

Before You Start

Gather these documents:

• Employer information (name, address, WSIB account number)
• Injury details (date, time, location)
• Medical records or doctor's notes
• Witness names (if applicable)
• Previous injury history (if relevant)

Tip: Your employer should have provided you with their WSIB account number. If not, ask your HR department.

Section-by-Section Guide

Part A: Personal Information

Fill in:

• Your legal name (as it appears on government ID)
• Date of birth
• Social Insurance Number (required for benefits)
• Home address
• Phone number and email
• Preferred language for communication

Common mistake: Using a nickname instead of legal name. WSIB matches your information against government records.

Part B: Employer Information

Provide:

• Employer's legal business name
• WSIB account number (7 digits)
• Your job title
• Date you were hired
• Your work schedule
• Your wage/salary information

Important: If you have multiple jobs, list the employer where the injury occurred.

Part C: Injury Details

This is the most critical section. Be specific and detailed.

Date and time of injury:

• Exact date (day/month/year)
• Approximate time
• Your shift (day/night/afternoon)

Location:

• Specific workplace location
• Building, floor, or room number if applicable
• If off-site, provide full address

What happened: Write a clear, chronological description:

Bad example: "I hurt my back at work."

Good example: "At approximately 2:30 PM on January 10, 2026, I was lifting a 50-pound box of parts from the floor to a shelf. As I lifted, I felt a sharp pain in my lower back and had to set the box down immediately. I reported to my supervisor right away."

Body parts injured:

• Check all affected areas
• Be specific (e.g., "lower back, left side" not just "back")
• Include any pain that appeared later

Part D: Medical Information

First aid received:

• What treatment you got at work
• Who provided it
• Date and time

Medical attention:

• Name of doctor/hospital
• Date of first visit
• Ongoing treatment
• Current restrictions

Time off work:

• Date you stopped working
• Whether you returned to work
• If returned, what date and duties

Part E: Previous Injuries

Be honest. WSIB will find out anyway through medical records.

If you've had similar injuries:

• List the date
• Describe the injury
• Note if it was work-related
• Explain how this is different

Note: Having a previous injury doesn't disqualify you. But failing to disclose it can hurt your credibility.

Part F: Witness Information

If anyone saw the injury happen:

• List their names
• Provide contact information
• Note their relationship (coworker, supervisor, etc.)

Witnesses strengthen your claim significantly.

Part G: Additional Information

Use this space to:

• Provide context WSIB should know
• Explain any unusual circumstances
• Clarify information from other sections
• Describe ongoing symptoms
