Business activity change

If you believe you are not classified properly, your business activity has changed or want to add a classification to your account, you can request a classification review.

Please provide a detailed description of your business activity, a link to your business website and/or any links to social media pages for your business.

Business activity change request

If you do not have a website, please email your request for a reclassification to employeraccounts@wsib.on.ca, along with the following:

  • account number in the subject line
  • a detailed description of your business activity
  • the date you began performing the business activity
  • three to five invoices supporting your business activity
  • contracts
  • promotional materials and/or purchase orders

We understand that not all materials may be available; please provide as much information as possible in order to confirm your business activity.

If you are requesting adding a new classification to your account, you will also need to confirm that your business activities are separate and distinct from each other and are not performed as part of the same contract.

If you have multiple business activities and want to remove one, you can email us to advise which business activity you would like removed from the account and the date you ceased performing it.

We will not separately classify a business’ operations that are considered ancillary (i.e., incidental to the employer’s business activity). More information and examples can be found under the ancillary operations section of the Classification Structure policy.
