Requirements Overview
The most critical requirement for operating a business in London, Ontario is Occupational Health and Safety Act Compliance. This is legally required and you cannot operate a business without it. The Act governs safe workplaces, proper training, protective equipment, hazard assessments, incident reporting, and ongoing safety programs. This is NON-NEGOTIABLE—view it as the foundation for everything else you do, because non-compliance can lead to fines, shutdowns, and real harm to workers.
Beyond safety, you must secure the core permits to operate: register your business name with ServiceOntario, obtain the necessary business licence, and ensure you have a valid Business Number (BN) from the Canada Revenue Agency. These registrations prove your business exists legally, allow you to open bank accounts and sign contracts, and enable you to hire people properly. Grouped together, these steps establish your official footing to operate in the Ontario market.
On the tax and payroll side, you’ll use your BN to handle GST/HST registrations if your taxable supplies exceed the threshold, and you’ll set up payroll deductions if you have employees. You may also need WSIB coverage to protect workers and comply with workplace injury laws, along with adherence to Employment Standards for wages, hours, and leaves. These items ensure you meet ongoing regulatory obligations and protect your business and staff.
Next steps: verify which requirements apply to your specific operation, then map out a practical 4–6 week plan. Start by confirming your business name with ServiceOntario, applying for a BN with the CRA, and pursuing the relevant licences. Set up GST/HST, payroll deductions, and WSIB if you have staff, and establish a basic safety and compliance routine. If you’re unsure, consider a quick consult with a business advisor to tailor this plan to your exact situation.
