NUANS in Canada: Choose and Secure Your Business Name

TL;DR: NUANS is Canada’s primary name search system for corporations and some business names. Use it to check for conflicts, then reserve or register before someone else does.

TL;DR: Pick a name with a strong distinctive element, run a NUANS search, check trademarks and domains, then file quickly—federal NUANS reports are time-limited.

Naming a business in Canada isn’t just creative work—it’s regulatory. NUANS (Newly Upgraded Automated Name Search) compares your proposed name to existing corporate names, business names, and trademarks, so you can avoid conflicts and rejections.

This guide covers how NUANS works, where it applies, and practical steps to lock down a name that will pass review and serve you long-term.

How NUANS Works: What It Checks and Why It Matters

NUANS is a database search that returns names that are the same as or similar to yours. Examiners (federal or provincial) use it to decide if your name is distinctive and not confusing with existing records. A NUANS report is typically required for federal named corporations and in several provinces for named entities. Numbered companies don’t need it.

Key point: NUANS doesn’t approve your name—it informs the decision. You still have to meet each jurisdiction’s naming rules.

Federal vs Provincial: Where NUANS Applies

NUANS is used federally and by some provinces/territories. Others run their own name systems. Broad rules of thumb:

• Federal incorporation: NUANS is standard for named corporations. Reports are time-limited (for federal filings, they must be recent at submission).
• Provinces using NUANS: Some use NUANS or a provincial NUANS variant for named corporations and certain business names.
• Provinces with their own systems: For example, British Columbia and Quebec use in-house name request systems rather than NUANS.
  

Always check your target registry’s current requirements. The tests for confusion and distinctiveness are similar across Canada, but procedures and forms differ.

Name Styles: Distinctive, Descriptive, and Legal

Good Canadian corporate names follow a simple pattern:

• Distinctive element: The unique part (e.g., “Maplecrest,” “Blue Owl”).
• Descriptive element: What you do (e.g., “Plumbing,” “Software”). Optional but helpful.
• Legal element: Required for corporations (e.g., “Inc.,” “Ltd.,” “Corp.,” “S.A.R.F. in French”).
  

“Distinctive-only” names can work if strong and unique. “Descriptive-only” names usually fail. Generic or geographic-only names (e.g., “Toronto Cleaning Inc.”) are high risk unless paired with a distinctive word.

How to Choose a Name That Can Pass

When brainstorming, aim for a distinctive element that is not commonly used in your industry. Consider appearance, sound, and meaning in both English and French (Canada-wide context). Examiners look for likely confusion across these dimensions, not just exact matches.

Avoid restricted terms unless you have permission (e.g., “bank,” “trust,” “engineer,” “architect,” “university,” professional designations). Some words require regulatory consent or proof of licensing. Government-like names (“Canada Revenue,” “RCMP,” “City of…”) are generally prohibited.

NUANS Name Search: Steps to Lock In Your Name

1. Shortlist names with a strong distinctive element. Keep 3–5 options.
2. Do quick screening: web search, social handles, and domain availability.
3. Check the Canadian Trademarks Database for identical or confusing marks in your class of goods/services.
4. Run a NUANS search (federal or provincial, as required). Use an authorised NUANS service provider or registry agent.
5. Review the report carefully: look for similar spelling, sound-alike names, acronyms, and translations.
6. Refine the name if needed (change the distinctive element, not just punctuation or pluralisation).
7. File promptly with your registry. For federal filings, the NUANS report must be recent when submitted.
8. Secure matching domains and social handles immediately after filing.

Avoid Rejection: NUANS Tips for Canadian Names

• Don’t rely on small tweaks. Adding “The,” changing punctuation, or switching plural/singular rarely solves confusion.
• Mind bilingual issues: consider French and English meanings. A conflict can arise in either language.
• Don’t bury the distinctive element. If your name is mostly descriptive, strengthen the unique portion.
• Watch for acronyms. If your name shortens to a common industry acronym, you could trigger conflicts.
• Be cautious with geographic terms. Combine them with a strong distinctive word.
  Check for restricted words early to avoid delays awaiting consents.
  

Check Trademarks and Domains Before You File

NUANS isn’t a full legal clearance. A name could pass NUANS but still infringe a registered or common-law trademark. Before committing:

• Search the Canadian Trademarks Database for exact and similar marks in relevant classes.
• Consider professional trademark advice if you plan to invest in brand marketing across Canada.
• Secure domain names (preferably .ca and .com) and major social handles to prevent brand confusion.
  

What a NUANS Report Includes and How to Read It

A typical NUANS report lists identical or similar corporate names, business names, and trademarks found in the database. Look for:

• Exact matches or near-exact variants in your jurisdiction.
• Similar sounding names or obvious abbreviations.
• Trademark listings that could conflict, especially in your industry.
  

If you see several close conflicts—especially in the same sector—consider revising your distinctive element. If conflicts are in other industries and the distinctive element is strong, your odds are better, but the examiner has the final call.

Costs, Timing, and Where to Order NUANS Reports

Fees and turnaround depend on the provider and jurisdiction. Many authorised NUANS members and registry agents offer online ordering; some registries let you bundle name review with incorporation. Reports are often available quickly, but name decision times vary by registry workload.

Important: For federal filings, a NUANS report is only valid for a limited period when you submit your application. If it expires, you’ll need a fresh report. Provincial validity periods and reservation options vary—check your registry’s current rules.

After NUANS: Reserve, Register, and Keep Records Current

• Reserve the name if your registry offers reservations, or proceed directly to registration/incorporation.
• Incorporate or register the business name in each province/territory where you operate, as required.
• Update CRA program accounts (e.g., GST/HST, payroll), bank records, licences/permits, and contracts with the exact legal name.
• If you later change your name, file amendments, update CRA and provincial accounts, and refresh branding assets and domains.
  

If you plan to operate in Quebec, review language requirements under the Charter of the French language. You may need a French name or version for registration and public signage.

Quick Checklist to Choose and Secure a Name

• Create 3–5 names with strong distinctive elements.
• Screen web, domains, and social handles.
• Search the Canadian Trademarks Database.
• Confirm whether your jurisdiction uses NUANS or a local name system.
• Order a NUANS report (or submit a name request) and review conflicts.
• Revise if needed; avoid minor tweaks—strengthen the distinctive piece.
• File promptly before your report or reservation window closes.
• Register for tax accounts, licences, and update records with the exact legal name.
  

Common Mistakes That Delay Approval

• Submitting descriptive or geographic-only names without a distinctive element.
• Ignoring trademarks because the domain looked free.
• Assuming federal approval guarantees smooth provincial registrations—rules and processes differ.
• Using restricted words without required consents.
• Letting the NUANS report or reservation expire before filing.
• Overlooking bilingual implications that create unintended similarity.
