How to raise an issue with the Commission

If you have not already done so, you should try to resolve the issue directly with the WSIB first. If you are not sure whom to contact at the WSIB, we would be happy to help refer you to the right person or process.

You can call us at 416-603-3010, or toll-free at 1-866-258-4383. If we are unable to answer your call, please leave a message with your name, telephone number, and claim or firm number. We will call you back within two business days.

You can also submit a complaint through the following methods:

• Online complaint form
• Email: complaints@fairpractices.on.ca
• Fax: (416) 603-3021
• Fax Toll-free: 1-866-545-5357

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.
