How do I file a WSIB complaint against a contractor?

If you need to file a WSIB complaint against a contractor in Ottawa, you'll typically contact WSIB's Health and Safety Contact Centre at 1-877-202-0008, though the specific process depends on whether it's a workplace safety issue or a coverage/clearance problem.

Types of WSIB Complaints in Ontario

Workplace Safety Violations: If a contractor or their workers are operating unsafely on your property (no safety equipment, unsafe practices, etc.), this goes to WSIB's Prevention Division. Call 1-877-202-0008 or report online at wsib.ca/healthandsafety.

Coverage Issues: If you discover a contractor doesn't have proper WSIB coverage when they should, or if there's been a workplace injury and coverage is being disputed, contact WSIB Customer Service at 1-800-387-0750.

Fraudulent Clearance: If you suspect a contractor provided fake WSIB clearance certificates, this is serious fraud that should be reported to WSIB's Investigation Services through their main number.

Before Filing Your Complaint

Always verify the contractor's WSIB status first at wsib.ca/clearances using their business name and account number. In Ontario, contractors with employees or subcontractors typically need WSIB coverage, but sole proprietors without employees often don't require it.

Check what type of work triggers WSIB requirements - most construction work does, but there are exceptions. If you're unsure whether coverage was required for your specific project, WSIB can clarify this when you call.

What Information You'll Need

Have ready the contractor's business name, address, and any WSIB account numbers from contracts or clearance certificates. Document the specific safety violations or coverage issues with photos, dates, and witness information if possible.

Keep copies of all contracts, clearance certificates, and correspondence with the contractor. If there was an injury on your property, you'll need incident details, medical information, and any first aid or emergency response records.

Ottawa-Specific Considerations

The City of Ottawa requires WSIB clearance for most construction permits, so if your contractor pulled permits without proper coverage, notify both WSIB and the City's Building Code Services at 613-580-2424.

For projects in Ottawa's older neighborhoods like the Glebe, Westboro, or Sandy Hill, where work often involves heritage properties or unique safety challenges, document any specific safety concerns related to the building's age or condition.

What Happens After Filing

WSIB will investigate legitimate complaints, which can result in orders for the contractor to obtain coverage, safety violations penalties, or prosecution for fraud. However, WSIB complaints don't directly help you recover money from bad contractors - that requires separate legal action.

If your complaint relates to poor workmanship rather than WSIB violations, contact Ontario's Consumer Protection office at ontario.ca/consumer or consider mediation through the Better Business Bureau.

Protection for Future Projects

Always verify WSIB clearance before work begins using wsib.ca/clearances, and never accept photocopied certificates - get originals or verify directly with WSIB. Include WSIB compliance requirements in your written contracts, and don't make final payments until you've confirmed ongoing coverage.

For complex projects in Ottawa requiring multiple trades, verify each subcontractor's WSIB status separately, as the general contractor may not cover all workers on site.
