Requirements Overview

The most critical requirement for operating a temporary help service in London is Occupational Health and Safety Act Compliance. This is a legal must-have, and you cannot legally run your business without it. It means putting in place a proper safety program, training for staff, hazard assessments, incident reporting, and ongoing workplace safety practices to protect workers and clients alike.

For day-to-day operations, focus on mandatory safety and governance steps. This includes staying compliant with health and safety rules (OHSA), ensuring Service Provider Workplace Safety Compliance, and obtaining WSIB coverage. You’ll also need the right permits and licences to legally operate: Employment Agency Licence, Ontario Temporary Help Agency Licence, and a Business Licence, along with registering your business name with ServiceOntario. Add Employment Standards Compliance to ensure fair pay, hours, and working conditions, and secure appropriate Commercial General Liability Insurance to protect your business from common risks.

From a registration and tax perspective, you’ll need to set up and maintain key numbers and registrations. This includes the Business Number (BN) with the CRA, GST/HST Registration, and Payroll Deductions Registration if you’ll withhold taxes for staff. It’s also important to register your business name (Ontario Business Name Registration via ServiceOntario) and ensure you have the appropriate licensing in place. If you handle personal information, you’ll also need PIPEDA compliance to protect client and candidate data.

You’ve got this. Next steps are straightforward: confirm OHSA and safety program requirements with your local regulators, apply for the necessary licences and name registration, then set up BN, GST/HST, and payroll registrations with the CRA. Build a simple compliance plan, obtain WSIB coverage and insurance, and draft privacy policies. If you’d like, I can outline a practical 4-week action plan to get you from now to compliant
