What is a WSIB clearance certificate and how do I verify it?

A WSIB clearance certificate is proof that an Ontario contractor has no outstanding debts with the Workplace Safety and Insurance Board and is in good standing with workplace safety requirements - it's essential protection for Ottawa homeowners hiring contractors.

In Ontario, any contractor you hire should provide a valid WSIB clearance certificate before starting work on your property. This certificate protects you from potential liability if a worker gets injured on your job site and the contractor hasn't been paying their WSIB premiums properly.

What WSIB Clearance Means

WSIB (Workplace Safety and Insurance Board) provides workplace injury insurance for Ontario workers. When contractors register with WSIB and pay their premiums, they get coverage for their employees. The clearance certificate proves they're current on payments and have no outstanding debts to WSIB.

Without valid WSIB coverage, if a contractor's worker gets injured on your Ottawa property, you could potentially be held liable for medical costs, lost wages, and other expenses - even if you're not at fault.

How to Verify WSIB Clearance in Ottawa

You can verify a contractor's WSIB clearance certificate online at wsib.ca/clearances. The verification process is straightforward:

Enter the contractor's business name or WSIB account number from their certificate. The system will confirm whether the clearance is valid and current. WSIB clearance certificates are typically valid for specific date ranges, so make sure the dates cover your project timeline.

You can also call WSIB directly at 1-800-387-0750 to verify clearance over the phone. Have the contractor's business information and certificate number ready when you call.

Red Flags to Watch For

Be cautious if a contractor says they don't need WSIB because they're a sole proprietor or work alone. While some legitimate sole proprietors may be exempt, many contractors who claim this are actually using subcontractors or employees without proper coverage.

Never accept a photocopy of an old clearance certificate. Always verify current clearance directly with WSIB. Some contractors will show expired certificates or certificates for different business names.

If a contractor can't provide WSIB clearance or their clearance doesn't verify, this is a major red flag. Don't proceed with hiring them, regardless of how competitive their quote might be.

Getting Clearance from Your Contractor

Request WSIB clearance certificates from all contractors before signing any contracts. For larger projects in Ottawa, ask for updated clearance if your project extends beyond the certificate's expiry date.

Legitimate contractors will readily provide WSIB clearance - it's a standard business requirement. If a contractor hesitates or makes excuses about providing clearance, consider this a warning sign about their professionalism and compliance with Ontario regulations.
