Requirements Overview
The most critical requirement for operating a business in Saint John is the Business Licence. This license is legally required to operate commercially in the city, and you cannot legally start or continue work without it. It’s non-negotiable: without a valid business licence, you simply can’t run a construction business in Saint John that’s compliant with local rules. Plan to apply early and keep it current with timely renewals.
For mandatory operational needs, your day-to-day activity hinges on health, safety, and permits. Your workforce must be covered under New Brunswick WorkSafeNB Employer Coverage, which ensures compliance with workers’ safety and compensation rules. In addition, ensure you have the necessary permits and approvals tied to your construction work and that your site adheres to the city’s safety and licensing expectations. Keeping these elements in place protects workers and reduces the risk of delays or fines.
On the business registration and tax front, you’ll need a Business Number (BN) from the federal government, plus New Brunswick Business Name Registration (SNB) if you’re using a named business. Depending on your structure, you may also need Partnership Registration or NB Corporation Registration. For taxes, register for GST/HST if your taxable revenue meets or exceeds the threshold, and set up Payroll D deductions Registration if you have employees. These registrations keep your finances and reporting clean and compliant.
Next steps: map out your business structure (sole proprietor, partnership, or corporation), secure the Saint John licence, and complete BN and SNB registrations. Then set up WorkSafeNB coverage and determine GST/HST and payroll needs. If you’d like, I can tailor a simple, step-by-step checklist based on your exact plan to keep you on track and moving forward with confidence.
