Requirements Overview

The most critical requirement for operating a water supply and irrigation systems business in Markham is Occupational Health and Safety Act Compliance. This is a legal obligation you cannot bypass, and you cannot legally operate without it. It means implementing proper safety practices, training workers, maintaining safe equipment and procedures, and following incident reporting requirements. This requirement is NON-NEGOTIABLE.

Beyond safety compliance, you’ll need the permits and standards that keep daily operations legal. Grouped together, this includes meeting Industrial Safety Standards, Environmental Compliance (Infrastructure), and Employment Standards Compliance to ensure fair treatment of workers. In addition, you’ll likely need a Business Licence from the Town of Markham, and, if your activities involve electricity for pumps or other infrastructure, an Electricity Generation/Distribution License. These operational and permit-related requirements ensure your day-to-day work is lawful and safe.

For registration and tax purposes, prepare to handle your Business Number (BN) Registration, Ontario Business Name Registration (ServiceOntario), GST/HST Registration, Payroll Deductions Registration, and WSIB Registration and Coverage. These registrations provide you with the official identifiers and coverage needed to bill clients, collect taxes, pay employees, and protect your workers.

You’ve got this. Start by confirming your compliance with OHSA and safety standards, then tackle the registrations in a logical order: register your business name and BN, set up GST/HST and payroll processes, and secure WSIB coverage. If you break the tasks into weekly milestones and use checklists, you’ll stay organized and steadily move toward a compliant, smoothly running operation. Encourage yourself to take the first step this week and seek local guidance if a licensing step is unclear.
