Requirements Overview
Starting a services-to-buildings business in Longueuil begins with getting your legal identity in place. The most foundational items are obtaining a Business Number (BN) and a Quebec Enterprise Number (NEQ), which you need to operate legally, invoice clients, and handle taxes. These numbers are non-negotiable; you cannot legally run or grow your business without them. They form the backbone for other registrations, payroll, and communications with government agencies.
Next come health, safety, and local permits. You will need a valid Business Licence to operate in Longueuil. If you form a partnership or a corporation, you’ll register that structure with the appropriate authority. If you hire employees, you’ll also set up Payroll Deductions Registration and the Quebec CNESST Employer Registration to cover workers’ compensation and workplace safety.
Business Registration & Tax: You’ll need to complete the Quebec business registration (REQ - Registraire des entreprises) to formalize your business name and structure. If you form a partnership you’ll go through Partnership Registration; if you form a corporation, Quebec Corporation Registration applies. Additionally, if you expect to bill for taxable goods or services, you’ll register for GST/HST (with the federal government) and manage any relevant provincial registrations.
Next steps: Confirm your business structure, apply for BN, NEQ, REQ, and a local licence; decide on partnership or corporation registration if applicable; set up GST/HST registration if you will bill taxable services; and arrange for payroll and CNESST if you hire staff. Take it one step at a time and consider a quick call with a local business advisor or the Quebec government’s business help desk to ensure you’ve got everything you need.
