How to check a drywall contractor's license in Ontario

  1. Open the drywall contractor's profile from the table below (or search Ontario listings by name). Check that C-9 appears among its classifications and that the primary status reads Clear. What C-9 covers.
  2. Before any money changes hands, verify the license on CSLB's own lookup. Our data comes from CSLB's weekly file, so a very recent change may not show here yet.
  3. Ask for the pocket license and a photo ID and match the name to your contract. Work of $1,000 or more needs a license (the $1,000 rule), and a down payment can't exceed $1,000 or 10% (down payment rules).
