Start your business on a clean foundation. ATS is a licensed CPA firm that incorporates companies federally or in Québec, registers you with the CRA and Revenu Québec, and sets up your GST/QST and payroll accounts — so your books, tax, and compliance are right from day one.
How do I incorporate a business in Canada or Quebec? You choose federal (Corporations Canada) or provincial (in Québec, the Registraire des entreprises / REQ) incorporation, reserve a name (NUANS or a Québec name search), file articles of incorporation, and then register the corporation’s tax accounts — a CRA Business Number plus GST/HST, QST (Revenu Québec), and payroll accounts as needed. ATS handles the full setup for you as a CPA-led firm, and gets your bookkeeping and tax accounts wired up at the same time.
Most incorporation headaches come later — a missing GST/QST registration, a payroll account that was never opened, a fiscal year-end chosen without thinking about tax, share structure that boxes you in. Because ATS is a CPA-led accounting firm and not just a filing service, we set your corporation up with the downstream tax and bookkeeping in mind. You get a company that is registered properly, with every government account you actually need open and nothing you don’t.
From first-time founders to sole proprietors ready to incorporate.
The full setup — company, tax accounts, and the books to run it.

From decision to a fully-registered, book-ready company.

We set up QuickBooks or Xero, walk you through what to keep, and hand over a company that’s ready to operate and stay compliant.
Anyone can file articles of incorporation. The value is in what comes next — the tax accounts, the year-end, the share structure, and the books that determine what you actually pay and how smoothly your first year goes. ATS is a licensed CPA firm, a member of the Ordre des CPA du Québec, with Canadian and US CPAs on staff, working in English and French. We’ve helped Canadian businesses for over a decade, and we set up your corporation so it fits the bookkeeping, payroll, and tax work you’ll need after launch.
Once you’re incorporated, ATS keeps everything running: monthly bookkeeping, payroll, GST/QST filing, and tax preparation — all from one Montréal firm serving businesses across Canada. Préférez le français ? Voir l’incorporation d’entreprise.
