Requirements Overview

The most critical requirement for operating a business in London, Ontario is Occupational Health and Safety Act Compliance. This is a legal obligation that covers a safe workplace, proper staff training, hazard assessments, and incident reporting. You cannot legally operate without meeting these duties, and non-compliance can lead to fines or even a shutdown. Start here by identifying safety responsibilities for your office and putting basic policies and recording practices in place.

Beyond safety, you’ll want solid operational readiness. Make sure you follow Service Provider Workplace Safety guidelines, which means keeping risk assessments, training, and emergency procedures up to date. You also must comply with Employment Standards, including fair pay, reasonable hours, breaks, and holiday rules. Protect your business and staff with Commercial General Liability Insurance and ensure WSIB coverage for any employees.

On the registration and tax side, you’ll need to sort out numbers and permits. Obtain a Business Number (BN) from the Canada Revenue Agency, and secure a Business Licence if your city requires it. If you’ll operate under a name other than your legal entity, register your Ontario Business Name with ServiceOntario. Plan for GST/HST registration if your revenue crosses the threshold, and set up Payroll Deductions Registration for employee withholdings.

Next steps: outline a simple, practical compliance plan, gather the required documents, and start the applications with CRA, ServiceOntario, and your insurer. Ask a local business advisor or accountant to review your plan, then tackle registrations one by one. With a clear path and steady progress, you’ll build a compliant, well-protected office in London and feel confident moving forward.
