Requirements Overview
The most critical requirement for operating a water supply and irrigation systems business in Toronto is Occupational Health and Safety Act Compliance. This is a legal must and you cannot operate without it. You’ll need a solid safety program, proper worker training, appropriate PPE, clear incident reporting, and safe work practices in place before you hire or start work. Treat this as non-negotiable from day one.
Beyond safety, you’ll need the mandatory operational permits and standards to run your business. This includes following Industrial Safety Standards for equipment and work practices, Environmental Compliance for your water infrastructure and any waste handling, and Employment Standards Compliance for how you treat and pay your team. If your work involves electrical systems, ensure any electrical licensing requirements are met (Electricity Generation/Distribution License if applicable). You’ll also want to secure a City permit and a Toronto business licence to operate legally in the city.
For business registration and tax matters, prepare to handle several registrations. You’ll need a Business Number (BN) from the CRA to manage taxes and payroll, and you should register for GST/HST if your revenue reaches the threshold. If you have employees, set up Payroll Deductions Registration and obtain WSIB Registration and coverage. You’ll also register your business name with ServiceOntario and secure a City of Toronto Business Licence. These steps keep you compliant with federal, provincial, and municipal requirements and help you avoid penalties.
Ready to move forward? Start with a clear safety plan and reach out to the right agencies to begin registrations. Talk to ServiceOntario and the CRA for the registrations, the City of Toronto for licences, and consider a quick consult with a regulatory advisor to make sure nothing slips through the cracks. With these steps, you’ll have a solid, practical path to launching your water supply and irrigation business in To
