Requirements Overview
The most critical requirement for operating a plumbing and heating equipment and supplies merchant wholesaler in Hamilton is Occupational Health and Safety Act Compliance. This is a legal obligation in Ontario, and you cannot legally run your business without meeting OHSA rules for a safe workplace, proper worker training, hazard assessments, and incident reporting. Treat this as non-negotiable from day one to protect your staff and stay on the right side of the law.
Beyond OHSA, your day-to-day operations must meet several mandatory safety- and permit-related requirements. Grouped together, these include Product Safety and Recall Obligations to ensure the items you stock are safe and that you can act quickly if a product issue arises; Employment Standards Compliance to follow wage, hour, and leave rules; WSIB Registration and Coverage to protect workers if injuries occur; and Commercial General Liability Insurance to cover common business risks. Waste Generator Registration is required where applicable, and if you handle imports or exports or sell tax-exempt items, you may need an Import/Export Business Number and a Vendor Permit for Retail Sales Tax Exemption.
For business registration and taxes, you’ll need to set up the key government identifiers and registrations. These include a Business Licence, Business Number (BN) Registration, Ontario Business Name Registration (ServiceOntario), GST/HST Registration, and Payroll D deductions Registration. If your activities involve importing or exporting, obtain an Import/Export BN, and if you plan to sell items under a tax-exempt arrangement, you may also need a Vendor Permit for Retail Sales Tax Exemption.
Next steps: start by confirming OHSA requirements with the Ontario government, set up your safety program and training, and align insurance and risk management. Then register the necessary business and tax numbers, and open the appropriate government accounts (ServiceOntario and CRA). With a clear checklist and time
