Who needs a clearance number?

What is a WSIB Clearance Number?

A clearance number is a certificate that the WSIB provides for free (view sample certificate). It proves that a business/contractor is registered with the WSIB and that their account is in good standing.

For an account to be in good standing, the contractor must meet these requirements:

  • Has an open account with the WSIB and has provided all registration information and required documents.
  • Is classified in the appropriate classification unit(s).
  • Has reported to the WSIB all required premium amounts and filed all required Premium Remittance and Reconciliation forms.
  • Has paid all premiums and other amounts owing.

A clearance number is valid for up to 90 days from the date of issue. You need to make sure that there is a valid clearance number in place for the full length of the work you’re doing. If the work being done lasts longer than the period the clearance number  is valid for, the clearance number can be renewed, as long as the account is still in good standing.
