Benefit-related overpayments

We may occasionally make an overpayment on your WSIB claim. If this happens, we'll send you a letter to let you know about the overpayment, and you’ll need to repay it.

There are a few different ways that you can repay the overpayment:

  • deductions from future benefit payments
  • online by: 
    • Visa or Mastercard (debit or credit)*
    • Visa/Mastercard debit*

*There is a 2.25 per cent service charge for using Visa or Mastercard credit, and a 1.75 per cent service charge for using Visa Debit, and Debit Mastercard payments. We don’t receive any part of this service fee; it goes directly to our online payment provider, Paymentus. 

  • by mail
  1. Payment method: Send a cheque payable to the Workplace Safety and Insurance Board.
  2. Include account number: Ensure your claim number is clearly written on the front of the cheque in the memo section.
  3. Mailing address: Mail your cheque to WSIB, PO Box 4115, Station A, Toronto ON M5W 2V3.

Please call us at 1-800-387-0750 if you have any questions.
