If you plan to import or export, you’ll also need an Import/Export Business Number. Payroll Deductions Registration is required if you have employees, and CNESST employer registration covers workers’ compensation obligations.
Business Registration & Tax: In Quebec and Canada, you’ll need key registrations and tax accounts. Secure a Business Number (BN) from the Canada Revenue Agency, a Quebec Enterprise Number (NEQ) from Registraire des entreprises, and register with the Quebec Registraire des entreprises (REQ) as applicable. You’ll also handle taxes by registering for GST/HST, plus payroll deductions registration if you have employees, and ensure CNESST-related employer obligations are in place.

Create a simple, time-bound checklist, gather official documents (proof of address, incorporation or partnership papers, IDs), and plan which agencies you’ll contact first.
