What you should do before you call us
A. Before you contact the Commission, take these steps to try to resolve your complaint with the WSIB:
- Contact the WSIB to try to resolve your complaint first. If you can, speak directly with the staff member responsible for the claim, issue or decision. Have your claim, firm or provider number handy. Explain what happened, what you think is unfair, and what you think they should do. Take notes – who you spoke to, on which date and anything they said they would do.
- If you are not satisfied, escalate your complaint by raising it with a WSIB manager and, if necessary, using the WSIB’s escalation process.
B. If you still think there is a fairness issue, you can contact the Commission.
You can call the Commission to discuss your concerns:
If you want to file a complaint in writing, fill out the Complaint Form and submit it online. Or you may print it from our website and send it to the Commission:
- By fax at: 416-603-3021
- Toll Free: 1-866-545-5357
- You can also send us an E-mail at: firstname.lastname@example.org. Please include a telephone number where we can contact you.
While we do accept complaints sent via regular mail, the Commission has a hybrid work model so there may be delays in receiving correspondence. As such, if you are able to, we encourage you to contact us via one of the methods noted above.
