Bill 119 requires businesses that hire contractors for renovations to obtain clearance certificates from those contractors, proving they are registered with and paying premiums to the Workplace Safety and Insurance Board (WSIB). The business is responsible for ensuring any contractors and subcontractors they hire have valid clearance certificates. Failure to do so could result in the business being liable for any unpaid WSIB premiums if a worker is injured. Clearance certificates are valid for only 90 days, so businesses must monitor contractors' compliance. Penalties for non-compliance include fines up to $25,000 for individuals and $100,000 for corporations.
