Requirements Overview
For operating a business that provides other support activities for air transportation in Longueuil, there isn't a single “one-and-done” certification. Instead, the starting point is completing a set of mandatory registrations and licenses. The core requirements you must obtain are the Business Number (BN) Registration, the Quebec Enterprise Number (NEQ) Registration, the Quebec Business Registration (REQ), and a valid Business Licence. These registrations are legally required to operate; you cannot legally run the business without them. Getting these in place first helps you interact with banks, suppliers, and government agencies smoothly.
Beyond registrations, you’ll want to stay on top of essential operational requirements that keep workers safe and compliant. Health and safety steps include registering with CNESST (Quebec’s workers’ compensation program) so injuries and workplace coverage are handled properly. If you hire employees, you’ll also need Payroll Deductions Registration to manage withholdings and remittances. Depending on the exact nature of your air-transport support services, you may need additional municipal or provincial permits, so plan for ongoing compliance as you grow.
For structure and taxes, consider how you’ll organize the business—Partnership Registration or Quebec Corporation Registration may apply depending on ownership. You’ll also manage sales taxes through GST/HST Registration if your activities meet the tax threshold. The BN, NEQ, and REQ numbers you obtained are used across government filings, including GST/HST and payroll accounts, so keep them accessible and up to date.
Next steps are practical and doable: gather the needed documents, decide on your business structure, and submit the registrations through the appropriate government portals. Set up your payroll and tax accounts now so you’re ready to hire and bill clients. If you’d like, I can help tailor a simple, step-by-step checklist and timeline for Longueuil based on your
