Requirements Overview
The most critical requirement for operating a business in Toronto is Occupational Health and Safety Act Compliance. This is a legal obligation you cannot bypass; without it you cannot legally run a business here. It means establishing a safe workplace, training staff, keeping records, and following reporting rules for injuries or incidents. Treat this as non-negotiable and build your setup around meeting all OSHA requirements from day one.
Next come the mandatory operational requirements that keep your day-to-day running compliant and safe. Health and safety ties to WSIB coverage to protect workers, and you should implement clear safety policies, training, and incident reporting. Depending on your work, you may also encounter security clearances and government program administration standards if you handle sensitive information or government contracts. Also ensure you meet Ontario employment standards, such as fair pay, overtime, and notice rights for staff.
On the business registration and tax front, you’ll need a Canada Revenue Agency Business Number (BN) to handle taxes and filings. You’ll likely also need an Ontario business name registration with ServiceOntario and a local business license. For taxes, register for GST/HST, and for payroll, set up payroll deductions with the CRA. If you have employees, arrange WSIB coverage. These registrations anchor your legal ability to bill clients, pay taxes, and hire staff.
Ready to get started? Gather your basic documents, then tackle each item in small steps: confirm OSHA compliance and safety planning, register the BN, apply for your Ontario name registration and business license, and set up GST/HST and payroll accounts. If you’re unsure, consult a local business advisor or use government portals for guided checklists. With clear milestones, you’ll move confidently toward a compliant launch.
