The name search report you need before incorporating with a word name in Ontario.
Verified. Last reviewed 2026-10-05. Always confirm with the official source before filing.
Step by step
- Choose your proposed name. Include a distinctive element, a descriptive element, and a legal ending (Inc., Ltd., Corp.).
- Order an Ontario-biased NUANS report. Order online through NUANS, or through a search house or incorporation service.
- Review the results. Look for identical or confusingly similar names. Similar names don't automatically block you, but they raise legal risk.
- File within 90 days. Submit your articles of incorporation through the OBR with the NUANS report number before it expires.
Ontario-biased vs federal NUANS
Ontario incorporations need an Ontario-biased report. Federal incorporations under the CBCA use a federal NUANS report. Using the wrong type can cause your filing to be rejected.
Do you need one?
- Word-name Ontario corporation: yes.
