Requirements Overview
The most critical requirement for operating a diet and weight reducing centre in Toronto is Occupational Health and Safety Act Compliance. This is a legal must and you cannot operate without it. It means putting in place safe work practices, giving staff proper training, conducting hazard assessments, keeping incident records, and ensuring a safe environment for clients during all activities. This is non-negotiable—without solid OHSA compliance, you simply cannot run the business.
Mandatory Operational Requirements include health, safety, and permits. In practice, make sure your facility meets local health and sanitation standards and that you have a valid municipal Business Licence. Establish clear emergency procedures, maintain basic first aid readiness, and provide ongoing staff training. If you have employees, you’ll also need to follow Employment Standards Compliance (wages, hours, leaves) to keep operations fair and legal.
Business Registration & Tax covers official numbers and reporting. Register your Ontario Business Name (ServiceOntario) if you’ll operate under a name other than your own. Obtain a Business Number (BN) from the Canada Revenue Agency, and set up GST/HST registration if your revenue hits the threshold or if you choose to register voluntarily. If you have employees, set up Payroll Deductions registration and ensure WSIB coverage for workplace injuries.
Next steps: map out a simple compliance plan and tackle forms one by one. Start with OHSA-related policies and a practical safety plan, then secure any required licensing with your city, register your business name and BN, and set up your tax accounts. If you’d like, hop on a quick call with a local small-business adviser to tailor a practical checklist and keep you confident as you launch.
