Requirements Overview
The most critical requirement for operating a lessor of nonresidential buildings (except miniwarehouses) in Ottawa is Occupational Health and Safety Act Compliance. This is a legal obligation for any workplace in Ontario, and you cannot legally operate without meeting safety rules, training, hazard controls, incident reporting, and ongoing safety management. It is non-negotiable; failure to comply can trigger fines, orders, or shutdown actions.
Mandatory operational requirements include staying compliant with safety rules and meeting local permits. Zoning Compliance ensures your building is allowed to lease nonresidential space. A City of Ottawa Business License is typically required to operate. If you offer short-term rentals, Short-Term Rental Registration may apply. Accessibility Standards (Hospitality) may also apply depending on your services and property. If you engage in real estate brokerage or property transactions, Real Estate Broker/Salesperson Registration is required to lawfully operate in that capacity.
Business Registration & Tax: You will need a federal Business Number (BN) and Ontario Business Name Registration (ServiceOntario). GST/HST Registration is required if you cross the threshold or choose to register. If you have employees, set up Payroll Deductions Registration and ensure WSIB coverage. You should also carry essential insurance, including Errors and Omissions Insurance (Real Estate) and General Liability Insurance, to protect your business, tenants, and property from common risks.
Next steps: Start with OHSA compliance, confirm zoning and licensing with the City of Ottawa, and set up your BN and name registration. Then connect with a local advisor to finalize registrations and insurance so you can move forward confidently. You’ve got this—taking these steps now sets a strong, compliant foundation.
