Requirements Overview
The most critical requirement for operating a plumbing and heating equipment and supplies (hydronics) merchant wholesalers in Saint John is Business Licence. This is a legal prerequisite to run a business in the city, and you cannot legally operate without it. The licence is issued by the City of Saint John and covers where you do business and what activities you’re allowed to do. Make sure you apply early and keep it current.
Mandatory Operational Requirements include health and safety obligations and product-related permits. You must meet Product Safety and Recall Obligations, ensuring the products you sell meet safety standards and that you follow recall procedures if a safety issue arises. You also need New Brunswick WorkSafeNB Employer Coverage to protect your employees; this means having coverage, maintaining a basic workplace safety program, and providing necessary training.
Business Registration & Tax: You’ll need a Canada Revenue Agency Business Number (BN) for tax accounts, payroll, and import/export if applicable. If you operate under a name other than your own, register with New Brunswick (SNB) for a business name. If you form a corporation, complete NB Corporation Registration. Depending on your revenue, you may need GST/HST Registration; if you have employees, set up Payroll Deductions; and if you import or export, obtain an Import/Export Business Number. Partnerships also require registration if applicable.
Next steps: map out the licenses you need, submit applications, and gather documents. Once you have the licence and BN/SNB/corporate registrations, you’ll be on solid ground to launch. Consider a quick check-in with a local business advisor or the Saint John business support team to confirm you’ve covered all the basics and stay on track.
