Requirements Overview
The most critical requirement for operating a hazardous waste treatment and disposal business in Markham is Occupational Health and Safety Act Compliance. This is a legal must and you cannot legally operate without it. This is non-negotiable. It means putting in place proper safety rules, worker training, incident reporting, and ongoing safety management before you start handling hazardous waste.
Mandatory operational requirements cover health, safety, and permits. Ensure you meet Industrial Safety Standards and related workplace safety rules, secure the Waste Management System License for handling and disposing of waste, and carry a valid Business Licence to operate in Markham. Environmental Compliance (Infrastructure) guidelines help protect air, water, and land around your site, while Employment Standards Compliance keeps staff rights and wages in place. Finally, WSIB Coverage ensures workers are protected if accidents happen.
Business Registration & Tax: You will need a Business Number (BN) from the Canada Revenue Agency and, if you’re using a trade name, Ontario Business Name Registration through ServiceOntario. For taxes, register for GST/HST, and if you have employees, set up Payroll Deductions Registration. These registrations simplify filings and keep you compliant with federal and provincial rules.
Next steps and encouragement: Start with confirming OHSA compliance and the city licenses, then map out a simple action plan with a safety program, permit deadlines, and training schedules. Gather the documents you’ll need for BN, Ontario name registration, and GST/HST, and consider talking to a local regulatory adviser or the Markham licensing office. With clear steps and the right registrations, you’ll move forward confidently.
