Requirements Overview
The most critical requirement for operating a Windsor business is Occupational Health and Safety Act Compliance. This is a legal obligation you cannot ignore, and you cannot legally operate without it. It covers keeping workplaces safe, training staff, reporting incidents, and managing risks. Non-negotiable compliance means committing to a safe work environment from day one and staying up to date with any changes in the rules.
Beyond safety, there are essential operational requirements to keep your doors open. You’ll need a valid Business Licence to legally operate in Windsor, and if you have employees you must arrange WSIB coverage to protect workers and your company. Other employment-related obligations—such as meeting Employment Standards requirements—also apply to ensure fair wages, hours, and leaves. If you structure your business through a holding or management company, you’ll want to make sure that registration and corporate requirements for that entity are properly handled as part of your setup.
From a registration and tax perspective, you’ll start with the basics: obtain a Business Number (BN) from the Canada Revenue Agency and register the Ontario Business Name with ServiceOntario if you’re using a specific trade name. Plan for GST/HST registration if your taxable revenue hits the threshold, and set up Payroll Deductions registration for employee payroll. Also ensure the holding/management company registration is in place if applicable, so your corporate structure is clear and compliant from the start.
If you’re ready to move forward, the next steps are straightforward: map out your safety program and confirm OHS compliance, secure the required licences and WSIB coverage, and then complete your business and tax registrations. Consider consulting a local business advisor to tailor these steps to your exact setup in Windsor, and you’ll be on solid footing to operate smoothly and legally.
