Requirements Overview

The most critical requirement for operating a brick, stone, and related construction material merchant wholesalers in Windsor is Product Safety and Recall Obligations. This is a legal must—you cannot legally operate a business that sells products without systems to ensure safety, track compliance, and respond quickly if a recall is necessary. It’s non-negotiable: you must have a clear plan for keeping products safe and for handling recalls if they occur.

Mandatory Operational Requirements: health, safety, permits. Beyond product safety, you must meet core health and safety obligations and keep the right permits in place. Ontario’s Occupational Health and Safety Act Compliance is non-negotiable for every workplace, with proper training, hazard controls, and incident reporting. You’ll also need to protect your workers with WSIB Registration and Coverage, and you should carry Commercial General Liability Insurance to cover possible injuries or property damage. Additional workforce obligations include Employment Standards Compliance and Payroll Deductions Registration. Environmental and regulatory permits may apply as well, such as Waste Generator Registration, and depending on your stock and activities, a Business Licence and a Vendor Permit for Retail Sales Tax Exemption.

Business Registration & Tax: You’ll need the right numbers and registrations to operate legally. Start with a Business Number (BN) from the Canada Revenue Agency and register your Ontario Business Name with ServiceOntario (or register a trade name if you’re not incorporating). A Business Licence is commonly required to run the wholesale operation. For taxes, register for GST/HST and ensure payroll deductions are properly remitted. If you import or export goods, you’ll also need an Import/Export Business Number. Depending on how you sell, a Vendor Permit for Retail Sales Tax Exemption may be needed as well.
