Requirements Overview

The most critical requirement for operating a business in Longueuil is the Quebec Physician Licence. This license is legally required for anyone who will practice medicine here, and you cannot legally run a medical office without it. It is non-negotiable: without this licence you cannot provide patient care. If you’re a physician, secure this credential first. If you’re a mental health professional, be sure you also hold the appropriate professional license for your field.

Beyond licensure, there are essential operational steps to keep patients safe and compliant. If you prescribe controlled drugs or substances, you’ll need a Controlled Drugs and Substances Authorization. For employer compliance and safety, register with Quebec CNESST for workers’ compensation and establish proper payroll processes for employee deductions. You’ll also need a valid Business Licence to legally operate a medical office. These items ensure safe practice, proper oversight, and a compliant workplace.

On the business side, you’ll handle registration and tax numbers to keep everything legit with the government. This includes Business Number (BN) Registration, Quebec Enterprise Number (NEQ) Registration, and Quebec Business Registration (REQ - Registraire des entreprises). If your practice will bill for services or products, you’ll likely need GST/HST Registration. If you form a partnership or a corporation, you’ll apply for Partnership Registration or Quebec Corporation Registration as appropriate. These registrations support proper taxation, reporting, and corporate governance.

Starting a medical office in Longueuil is a clear, doable process—just tackle it step by step. Begin with licensing, then secure the health and safety registrations, followed by the business registrations and tax registrations. Gather documents, map out your practice structure, and consult a regulatory or tax professional to keep you on track. With these pieces in place, you’ll be well positioned to serve patient
