Requirements Overview
The most critical requirement for operating a business in Quebec City is Business Number (BN) Registration. This BN is issued by the Canada Revenue Agency and is legally required to handle taxes, payroll, and general business activity. You cannot legally operate a plumbing, heating, and air-conditioning contracting business without it. In addition, you will typically need a Quebec Enterprise Number (NEQ) and to complete the Quebec Business Registration (REQ) for your chosen structure (partnership or corporation).
Mandatory Operational Requirements: Health and safety come first. If you hire employees, you must register with the Quebec CNESST for workers’ compensation and set up payroll deductions. You’ll also need to follow Quebec and local guidelines for plumbing, heating, and air-conditioning work, and obtain any required permits or inspections before starting jobs. These steps protect your crew, clients, and your business from avoidable risk.
Business Registration & Tax: The BN, NEQ, and REQ establish your official business identity in Canada and Quebec. If your business form is a partnership or a corporation, you’ll need the appropriate registration for that structure. GST/HST registration is required for taxable sales (or when you meet the revenue threshold), and Payroll Deductions registration is needed to remit employee withholdings.
