Requirements Overview

The most critical requirement for operating a business in Longueuil is Business Number (BN) Registration. This federal number is the gateway to taxes, payroll, and many other admin tasks your company will need to function. Without a BN you cannot legally run the business or file taxes, and you won’t be able to access other essential registrations. This requirement is non-negotiable, so start here and secure your BN as soon as you’ve chosen your business name and structure.

Next come the mandatory operational requirements: health, safety, and permits. In Quebec you should plan to register for the CNESST Employer Registration to cover workers’ compensation and workplace safety, ensuring your team is protected. You’ll also typically need a valid Business Licence from the City of Longueuil to legally operate construction work. Depending on how you structure your company, you may also need to complete Partnership Registration or Quebec Corporation Registration to formalize who owns and runs the business.

On the business registration and tax side, you’ll handle Quebec-specific identifiers and tax numbers. You’ll obtain the Quebec Enterprise Number (NEQ) and Registraire des entreprises (REQ) registrations, and you’ll set up tax accounts such as GST/HST and Payroll Deductions Registration. These numbers and registrations are essential for charging and remitting sales tax, as well as handling employee payroll withholdings.

You’ve got this. Next steps: secure your BN, then move on to NEQ/REQ, the city licence, CNESST registration, and GST/HST plus payroll registrations. If you’d like, I can lay out a simple 60-day action plan to keep you on track and avoid delays.
