Requirements Overview
The most critical requirement for operating a business in Saint John is the Saint John business licence. This licence is issued by the City of Saint John and you cannot legally run a business here without it. It’s non-negotiable: operate without a valid licence and you’re at risk of fines or being forced to shut down. Once you’re licensed, you can tackle the rest with confidence.
Next come mandatory operational requirements to keep things compliant and safe. If you collect personal information, you must follow PIPEDA—have a privacy policy, limit what you collect, and protect data. If you hire employees, you’ll need WorkSafeNB employer coverage and basic safety policies. These items are essential for daily operations and the long-term reliability of your professional services.
On the business registration and tax side, prepare several numbers. You’ll likely need New Brunswick Business Name Registration (SNB), and if you form a partnership or NB corporation, register accordingly. You’ll also have a Canada Revenue Agency Business Number (BN) for tax accounts. GST/HST registration may be required if your revenue meets the threshold, and payroll deductions registration is necessary if you have employees.
Next steps: decide your business structure, then tackle registrations in that order. Check with Service NB and Saint John’s licensing office for specifics, set up your privacy plan, and secure WorkSafeNB coverage if you have staff. If you’d like, I can tailor a simple, step-by-step plan based on your exact services and team size to keep you moving toward a compliant launch.
