Incorporating in Ontario: Everything You Need to Know

Ontario is home to the majority of Canadian small businesses. This guide walks through the Ontario Business Corporations Act, costs, timelines, and what you'll receive after filing.

7 min read Updated April 21, 2026

Ontario incorporations are governed by the Ontario Business Corporations Act (OBCA) and processed through the Ontario Business Registry (OBR), which launched in October 2021. The OBR replaced a paper-heavy process with a fully online system, and most incorporations are now completed in minutes rather than weeks.

What is required to incorporate in Ontario

  • A corporate name (either a named corporation with a NUANS report, or a numbered corporation).
  • Articles of Incorporation describing share structure and any restrictions on share transfers or business activities.
  • One or more incorporators — can be individuals or corporations.
  • At least one director. Ontario removed its 25% Canadian-resident director requirement in July 2021.
  • An Ontario registered office address. A P.O. box alone is not acceptable; a civic address is required.
  • Names and addresses of directors and officers for the first notice.

Costs

ItemCost (Ontario)
Government filing fee (online)$300
NUANS report (if using a named corporation)Approximately $8–$40 depending on the search house
Name pre-search (optional, reduces NUANS rejection risk)Varies
Minute book setup (optional but recommended)Varies by provider

Numbered corporations skip the NUANS step entirely, which is both faster and cheaper. The trade-off is that the corporation will need to register a separate operating name if it wants to do business under a branded name rather than "1234567 Ontario Inc."

Timeline

For a straightforward Ontario incorporation, the typical timeline is:

  • Name selection and NUANS report: same day (a report is generated in minutes).
  • Articles of Incorporation drafting: same day.
  • Filing with the Ontario Business Registry: usually processed immediately or within 24 hours.
  • Initial Return (Form 1) confirming directors and registered office: due within 60 days of incorporation.

What you receive after filing

  • Certificate of Incorporation with your incorporation date and Ontario Corporation Number (OCN).
  • Stamped Articles of Incorporation.
  • Corporation profile showing current directors, officers, and registered office.
  • Access credentials for the Ontario Business Registry.

After incorporation

A new Ontario corporation typically has a few immediate follow-up tasks:

  • Pass an organizational resolution issuing the initial shares and appointing officers.
  • Adopt by-laws — the general rules governing the corporation's internal affairs.
  • Register for a CRA Business Number and any relevant tax accounts (HST, payroll, corporate income tax).
  • Open a corporate bank account — banks will require the Articles, the Certificate, and a recent corporate profile.
  • Set up the minute book and record the organizational resolutions in it.
  • Calendar the annual return deadline (due within six months after fiscal year-end).
