What is a WSIB clearance certificate and why is it important?

A WSIB clearance certificate is a document that proves an Ontario contractor has no outstanding debts with the Workplace Safety and Insurance Board - and it's absolutely crucial for Ottawa homeowners to verify before hiring any contractor.

In Ontario, all contractors with employees must register with WSIB and maintain coverage for workplace injuries. The clearance certificate shows they're current on all premiums and have no outstanding balances. This matters enormously because if you hire a contractor without valid WSIB coverage, you could become liable for any workplace injuries that occur on your property.

How WSIB Protects Ottawa Homeowners

When a contractor's employee gets injured on your Ottawa property, WSIB coverage protects you from potential lawsuits and liability claims. Without it, an injured worker could sue you directly as the property owner. Given that construction work inherently involves risks - from falls to electrical hazards - this protection is essential for any project, whether it's a simple deck repair in Kanata or a major kitchen renovation in the Glebe.

The certificate also indicates the contractor runs a legitimate business. Contractors who skip WSIB registration often cut other corners too - like proper licensing, insurance, or building permits. It's frequently one of the first red flags in identifying fly-by-night operators.

How to Verify WSIB Clearance in Ottawa

Getting verification is straightforward through WSIB's online system. Visit wsib.ca and use their clearance certificate lookup tool. You'll need the contractor's business name and WSIB account number (which they should provide readily). The system shows their current status and any restrictions.

Legitimate contractors will provide their WSIB information upfront and often include it in their quotes. If a contractor hesitates, claims they don't need it, or says they'll "handle it later," that's a major red flag. Never start work without confirming active coverage.

What to Watch For

Be especially cautious of contractors who claim they don't need WSIB because they work alone. While sole proprietors without employees aren't required to register, many choose optional coverage for their own protection. More importantly, if they hire any subcontractors or helpers during your project, those workers must be covered.

Some contractors try to avoid WSIB by misclassifying employees as independent contractors. This creates liability gaps that could leave you exposed. Always verify that everyone working on your Ottawa property is properly covered.

Integration with Other Verifications

WSIB clearance works alongside other essential verifications for Ottawa contractors. Check their ESA electrical license at esasafe.com if they're doing electrical work, verify TSSA certification for gas work at tssa.org, and confirm they have proper liability insurance. The City of Ottawa Building Code Services (613-580-2424) can also verify if they've pulled permits properly for previous projects.

For any significant renovation project in Ottawa - whether in Barrhaven, Orleans, or downtown - requiring WSIB clearance should be non-negotiable. It's a simple step that provides crucial protection and helps ensure you're working with a professional, legitimate contractor.
