Requirements Overview
The most critical requirement for operating a business in Markham is Occupational Health and Safety Act Compliance. This is a legal obligation you cannot bypass, and you cannot legally run an all‑support services business here without putting safety first. It means having a safe workplace, providing necessary training, keeping proper records, reporting hazards, and following Ontario’s OHSA rules. This requirement is non-negotiable and must be in place before you hire staff or start servicing clients.
Beyond safety, you’ll need to cover mandatory operational requirements. Make sure you have Service Provider Workplace Safety Compliance and Employment Standards Compliance so your workers are protected and treated fairly. You’ll also want WSIB coverage to support any work‑related injuries, and Commercial General Liability Insurance to shield your business from common risks. Don’t forget the municipal Business Licence, which you’ll typically need to legally operate in Markham.
On the regulatory and tax side, set up the essential registrations. You’ll need a Business Number (BN) registration with the Canada Revenue Agency, and Ontario Business Name Registration through ServiceOntario. If your revenue crosses thresholds, you’ll also register for GST/HST, and if you have employees, Payroll Deductions Registration will be required.
Next steps: map out a simple compliance plan, start the registrations, and reach out to your local licensing office to confirm any city‑specific rules. Gather necessary documents, set realistic timelines, and consider consulting an accountant or business advisor to keep you on track. With these pieces in place, you’ll be ready to operate confidently and legally in Markham.
