NUANS stands for Newly Upgraded Automated Name Search. It is a database operated under contract with the federal government that contains corporate names, business names, and trademarks registered across Canada. A NUANS report compares a proposed corporate name against that database and produces a list of similar existing names so the government can decide whether yours is distinct enough to register.
When a NUANS report is required
- Federal incorporation under the CBCA — always required if you're registering a named corporation.
- Ontario incorporation under the OBCA — required for named corporations.
- Alberta, Saskatchewan, Manitoba, New Brunswick, Nova Scotia, Newfoundland and Labrador, PEI — all use NUANS for named corporations.
- Quebec, British Columbia, and the territories — use separate name systems, not NUANS.
- Numbered corporations (e.g., 1234567 Canada Inc.) — no NUANS search required in any jurisdiction.
How a NUANS search works
A NUANS report is ordered through an authorized NUANS search house. You submit the proposed corporate name, the search house runs it against the database, and you receive a report — usually within minutes — listing approximately 20 to 30 similar names already in use. A NUANS report is valid for 90 days from the date it is generated. The filing must be completed within that window or the report expires and a new one is required.
The government does not make the final decision based solely on the report. A corporate examiner (federal or provincial) reviews the report and the proposed name, weighs distinctiveness and potential confusion with existing names, and either approves or rejects the name.
The anatomy of a corporate name
A compliant Canadian corporate name has three parts:
- Distinctive element — a unique or coined word (e.g., "Maplewind").
- Descriptive element — describes the business activity (e.g., "Consulting").
- Legal element — indicates limited liability: Inc., Incorporated, Corp., Corporation, Ltd., Limited, Limitée, or Ltée.
A name that is only descriptive ("Canadian Consulting Inc.") will almost always be rejected. A name that is distinctive but very close to an existing registered name ("Maplewind Consulting Inc." vs. an existing "MapleWynd Consulting Ltd.") may also be rejected on confusion grounds.
What if your first choice is unavailable
There are three common fallbacks. You can propose a variation with a more distinctive element; you can add a geographic or descriptive modifier that creates meaningful separation; or you can incorporate as a numbered corporation now (for example, 1234567 Canada Inc.) and adopt an operating name later through a business-name registration. The numbered route is the fastest path when speed matters more than branding.
