Closing your account

You may ask to close your account when you have stopped operating your business or no longer have employees. You must notify us within 10 days of this happening.

You must complete the account closure request form to close your account.

Please note: we cannot process future dated closures.

How to close an account in construction

If you operate a business that falls under a construction North American Industry Classification System (NAICS) code, you should complete the account closure request form to close your account. However, no longer having employees does not automatically indicate the closure of an account as the owner(s) of the business may still have to report and pay insurable earnings for themselves.

How to close an account with non-mandatory coverage

If you operate a business that has a non-mandatory NAICS code and want to de-elect coverage, please send a request to employeraccounts@wsib.on.ca. The account will be closed the day the WSIB receives the request to cancel coverage.

Next steps

Once we receive notification of closure, you will receive a confirmation letter in the mail including next steps, if applicable. Please note that insurable earnings will have to be reported and paid up to the date of closure.
