Requirements Overview
In Longueuil, the foundation you must set up before you start operating is a set of mandatory registrations and licenses. The core requirements are the Business Number (BN) Registration, Quebec Enterprise Number (NEQ) Registration, Quebec Business Registration (REQ - Registraire des entreprises), and a Business Licence. These are non-negotiable legal basics; you cannot legally run a business in Quebec without them. They connect you to federal and provincial tax systems, payroll, and reporting, and they enable you to contract with clients and suppliers.
Operational compliance covers health, safety, and program-specific requirements. Ensure your Business Licence is current for your activities. Depending on your sector, you may encounter Security Clearance and Screening requirements, and if you participate in government programs you’ll need to meet Government Program Administration Standards. If your business structure involves a partnership, you’ll complete Partnership Registration. For staff, you’ll need CNESST Employer Registration for workers’ compensation and Payroll Deductions Registration to handle payroll taxes and withholdings.
On the registration and tax side, you’ll use your BN for federal tax and payroll activities, while NEQ and REQ come from Quebec’s Registraire des entreprises. If you form a corporation, you’ll also need Quebec Corporation Registration.

CNESST Employer Registration is essential for providing workers’ compensation coverage.
