Requirements Overview
The most critical requirement for operating a siding contractor in Montreal is Quebec Business Registration (REQ - Registraire des entreprises). This registration is legally required to run a business in Quebec, and you cannot operate without it. It’s non-negotiable, so getting registered with the Registraire des entreprises is the essential first step before you do anything else.
Mandatory operational requirements cover licenses, safety, and basic compliance you’ll need day to day. Start with the municipal side: obtain the Montreal business license to legally operate from the city. If you hire workers, you’ll also need to address health and safety obligations, which includes registering for the Quebec CNESST (the workers’ compensation system). Depending on the scope of your projects, you may also encounter construction-related permits or other local requirements, so plan for compliance from the start.
Business registration and tax basics come next. After your REQ registration, you’ll have the Quebec Enterprise Number (NEQ), and you’ll also need a Business Number (BN) from the federal government if you handle payroll or file corporate taxes. You’ll likely register for GST/HST (with the Canada Revenue Agency) and, if applicable in Quebec, for provincial sales tax (QST) with Revenu Québec. If you hire employees, you’ll also manage Payroll Deductions registrations with the appropriate tax authorities.
You’re taking solid, practical steps toward a lawful, well-structured business. Next steps: confirm your Montreal licensing requirements, complete your REQ/NEQ registration, secure your BN and GST/HST registrations, set up CNESST coverage, and if you hire staff, arrange payroll deductions. If you tackle these one by one and keep a simple compliance calendar, you’ll stay on the right side of the rules and be ready to grow. You’ve got this—take it step by step and you’ll be ready to start bidding on jobs with confidence.
