Requirements Overview
The most critical requirement for operating a business in Longueuil is the Business Number (BN) Registration. This is a legally required identifier you cannot operate without, because it’s used to interact with federal and provincial programs, file taxes, and handle government reporting.

Mandatory Operational Requirements include several health, safety, and permission-related steps. If your work touches national security, you may also need Security Clearance and Screening as part of your onboarding or contract work.

If you plan to work with partners, Partnership Registration may be necessary, and you’ll also need to ensure Quebec CNESST Employer Registration is in place to cover workers’ compensation and safe workplace obligations.
Business Registration & Tax covers the formal entity and numbers you’ll need to operate smoothly. In Quebec, you’ll typically complete the Quebec Business Registration (REQ - Registraire des entreprises) and obtain the Quebec Enterprise Number (NEQ).
