Requirements Overview
The most critical requirement for operating a lessor of nonresidential buildings in Markham is Occupational Health and Safety Act Compliance. This is a legally required standard, and you cannot legally run your operation without meeting OHSA rules and maintaining a safe environment for workers and tenants. It is non-negotiable and foundational to everything else you do.
Operational readiness also means staying on top of health, safety, and licensing, plus practical risk management. In this category you’ll need WSIB coverage and appropriate insurance (Errors and Omissions Insurance for Real Estate and General Liability Insurance) to protect your business and clients. You should also align with Employment Standards Compliance and Payroll Deductions obligations for any staff. On the licensing side, ensure you have a Business Licence and comply with Accessibility Standards (Hospitality) where applicable. If you’re involved in licensed real estate activities, you must have Real Estate Broker/Salesperson Registration, and if you manage properties you may need a Property Management License. Keeping these pieces in place helps you avoid penalties and operate smoothly.
Business Registration & Tax: You’ll need to handle the more administrative side of starting up. This includes Ontario Business Name Registration (ServiceOntario) and a Business Number (BN) Registration to interact with government programs and agencies. For ongoing tax compliance, you’ll also want GST/HST Registration. If you have employees, you’ll manage Payroll Deductions Registration as part of payroll processing.
Next steps and encouragement: Start by confirming OHSA compliance and assembling your core licenses and insurance. Then set up your BN and Ontario business name registration, and apply for GST/HST (and payroll-related registrations if you have staff). I’m happy to help you map a practical, step-by-step checklist tailored to your portfolio and deadlines—you’ve got this, and taking it one step at
