Requirements Overview
The most critical requirement for operating a diet and weight reducing center in London, Ontario is Occupational Health and Safety Act Compliance. This is a legal obligation for every workplace, and you cannot legally run a center without meeting its requirements. It means providing a safe environment for clients and staff, delivering appropriate training, maintaining safe equipment, and having a clear process to report and address any incidents. This is non-negotiable.
Beyond safety, you’ll need to cover mandatory operational requirements such as health and safety safeguards, insurance coverage, and the necessary permits and registrations. This includes complying with Employment Standards, obtaining a business licence as required by the City of London, and registering your business name with ServiceOntario if you’ll use a name other than your own. Grouping these items helps keep your day-to-day running lawful and protects both you and your clients.
On the business registration and tax side, you’ll want to secure a Business Number (BN) from the CRA and related registrations. If your activity requires charging GST/HST, register for that as well. If you have employees, set up Payroll Deductions Registration. And if you operate under a brand name, make sure Ontario Business Name Registration is complete. These numbers and registrations are essential for proper reporting, remittance, and compliance.
Next steps: map out a practical compliance checklist and start with occupancy, safety, and licensing requirements. Then connect with ServiceOntario and the City of London for licences, set up your BN with the CRA, and arrange GST/HST and payroll registrations as needed. You can do this step by step—secure the essentials first, then build your compliant, client-friendly business with confidence.
