NUANS Name Search in Canada — Complete Guide for Business Owners

Before you can incorporate a named corporation in Canada — federally or in most provinces — you need to confirm that your proposed corporate name is available. The primary tool for this is a NUANS Report (Newly Upgraded Automated Name Search). This guide explains what NUANS is, when you need it, how to interpret the results, and how it differs from a provincial name search.

What Is NUANS?

NUANS is a national automated database of existing Canadian corporate names and trademarks, maintained by Corporations Canada (part of Innovation, Science and Economic Development Canada). A NUANS name search compares your proposed corporate name against:

• All existing federal corporate names under the CBCA
• All existing provincial and territorial corporate names across Canada
• All registered and pending Canadian trademarks from the Canadian Intellectual Property Office (CIPO)

The result is a NUANS Report — a list of existing names and trademarks that are identical to, or confusingly similar to, your proposed name.

When Is a NUANS Report Required?

A NUANS Report is required whenever you want to incorporate or register a named corporation at the federal level or in most provinces. Specifically:

• Federal incorporation (CBCA): A NUANS Report is mandatory and must be less than 90 days old at the time of filing. The report must be submitted with your Articles of Incorporation.
• Ontario: A NUANS Report is required for name approval.
• Alberta: A NUANS Report is required (for a named corporation — see how to incorporate in Alberta).
• Manitoba: A NUANS Report is required.
• Saskatchewan: A NUANS Report is required.
• New Brunswick, Nova Scotia, PEI: Required.
• Northwest Territories, Nunavut, Yukon: Required.
• British Columbia: BC uses its own provincial Name Request (NR) process through the BC Registry, not the federal NUANS system.
• Québec: Québec has its own separate name availability check through the Registraire des entreprises, not the federal NUANS system.
• Newfoundland: Uses a provincial name search.

What Does a NUANS Report Show?

A NUANS Report generates a list of names from the database that are similar to your proposed name, ranked by degree of similarity. The report includes:

• Exact matches (identical or near-identical names)
• Names with similar wording, spelling, or sound
• Names of similar type or nature (especially for industry-specific names)
• Registered Canadian trademarks that could conflict with your proposed name

The report does NOT itself approve or reject your name. It is a search result. A human reviewer (either you, your lawyer, or the corporate registry) then evaluates the results to determine whether your proposed name is available.

How to Interpret a NUANS Report

A NUANS Report lists conflicting names in order of similarity score. When reviewing the results, consider:

Identical names: If an identical name already exists, your proposed name will be rejected outright.

Confusingly similar names: Even if your proposed name is not identical, it may be rejected if it is confusingly similar to an existing name — meaning an ordinary person could confuse the two companies. Factors include sound, spelling, and the goods or services associated with the name.

Distinctive vs. descriptive names: A name that is purely descriptive of your business ("Ontario Accounting Services Inc.") is harder to protect and may face more scrutiny. A distinctive, invented, or unique name ("Acmexor Financial Inc.") is easier to approve.

Trademarks: If a registered trademark is similar to your proposed name and covers related goods or services, your name may be rejected even if no identical corporate name exists.

The Difference Between a NUANS Report and a NUANS Pre-Search

A pre-search (sometimes called a preliminary name search) is an informal check — typically done through an online tool or service — to get a quick sense of whether your proposed name has obvious conflicts. Pre-searches are free or low-cost but are not official and cannot be submitted with incorporation documents.

A full NUANS Report is the official government-database search. It costs approximately $75–$100 and is valid for 90 days from the date it is generated. Once you obtain a NUANS Report, you must use it before it expires.

How Long Is a NUANS Report Valid?

Federal NUANS Reports are valid for 90 days from the date they are generated. You must file your Articles of Incorporation (or the provincial equivalent) before the report expires, or you will need to generate a new report and pay the search fee again.

NUANS Reports for Federal vs. Provincial Incorporation

Aspect	Federal (CBCA)	Ontario	BC	Québec
Search system	Federal NUANS	Federal NUANS	BC Name Request (NR)	REQ name search
Report validity	90 days	90 days	56 days	Varies
Who approves the name	Corporations Canada	Service Ontario	BC Registrar	Registraire
Can be done online?	Yes	Yes	Yes	Yes

What Happens After a NUANS Report?

If the NUANS Report shows no conflicts (or manageable conflicts), you submit the report with your incorporation documents. The registry reviews the name and either approves it (and the corporation is incorporated with that name) or requests changes.

If the name is rejected, you revise the proposed name and either generate a new NUANS Report or, in some cases, submit a new search within the same report cycle.

Numbered Corporations: Avoiding the NUANS Requirement

If you do not need a named corporation immediately, incorporating as a numbered corporation (e.g., "1234567 Ontario Inc." or "123456 Canada Inc.") completely bypasses the NUANS requirement. Numbered corporations receive the next available number automatically. You can later file an Articles of Amendment to add a name — after generating a NUANS Report at that time.

Many entrepreneurs incorporate as a numbered corporation to start quickly, then add a name once the business concept is validated.

Corporate Name Requirements

Regardless of whether a NUANS Report comes back clear, your proposed corporate name must comply with naming rules:

• Must include a legal element: "Inc.", "Incorporated", "Ltd.", "Limited", "Corp.", "Corporation" (or French equivalents)
• Must be distinctive — not purely descriptive or generic
• Must not be misleading (e.g., cannot suggest government affiliation or use controlled words like "Bank," "Insurance," or "Trust" without proper licensing)
• Must not contain words that are prohibited or restricted under federal or provincial regulations
