Requirements Overview

The most critical requirement for operating a business in Longueuil is the Business Number (BN) Registration. This federal registration is legally required and you cannot operate a construction business without it. It ties your company to the Canada Revenue Agency for tax accounts, payroll, and other federal obligations, so getting a BN in place is non-negotiable.

Next, focus on operational health, safety, and permits. You must register with the Quebec CNESST for workers’ compensation if you have employees. A valid Quebec Business Licence is also required to legally perform construction work in Longueuil. Depending on how you set up your company, you may need to complete Partnership Registration or Quebec Corporation Registration. And if you hire staff, you’ll handle Payroll Deductions Registration as part of payroll compliance.

For Business Registration and Tax, your entity will also need numbers you can rely on when doing business in Quebec and across Canada. Ensure you have a Quebec Enterprise Number (NEQ) and follow through with Quebec Business Registration (REQ - Registraire des entreprises). You’ll also need GST/HST Registration for tax reporting on your taxable activities. If you employ people, plan for Payroll Deductions Registration as part of your ongoing payroll obligations.

You’re taking important first steps toward a solid foundation. Start by visiting the official portals (Registraire des entreprises for NEQ/REQ, CNESST for workers’ comp, and Revenu Québec/CRA for BN-related filings). Gather the necessary documents, map out your company structure, and set a realistic timeline. With these pieces in place, you’ll be well on your way to launching your multifamily construction project in Longueuil—confidently and compliant.
