Your business name is one of the first things customers, partners, and investors will see. In Canada, it’s also a legal requirement — and getting it wrong can mean rejected filings, trademark conflicts, or expensive rebranding down the road.

Here’s how to choose a strong business name and protect it properly.

What makes a good business name?

Before diving into the legal requirements, think about what makes a name work for your business:

  • Memorable — Easy to spell, say, and recall
  • Descriptive enough — Gives a hint about what you do
  • Unique — Stands out from competitors in your space
  • Scalable — Won’t limit you if your business grows or pivots
  • Domain-available — Check if the .ca or .com is available early

Every Canadian business name must follow specific rules, whether you’re a sole proprietor or incorporating.

For corporations

Your corporate name must include three elements:

  1. Distinctive element — The unique part (e.g., “Preferway”)
  2. Descriptive element — What you do (e.g., “Business Services”)
  3. Legal element — Inc., Ltd., Corp., or their French equivalents

Example: Preferway Business Services Inc.

Alternatively, you can incorporate with a numbered company (e.g., 12345678 Canada Inc.) and register a trade name separately.

For sole proprietors

If you’re operating under any name other than your own legal name, you must register that business name in your province.

How to search for name availability

NUANS search (federal and most provinces)

NUANS (Newly Upgraded Automated Name Search) checks your proposed name against existing federal and provincial business names and trademarks.

1

Draft 2–3 name options

Have backups ready in case your first choice is taken or too similar to an existing name.

2

Order a NUANS report

Reports cost $13.80 through Innovation Canada or authorized search houses. Results are valid for 90 days.

3

Review the results

Look for exact matches and similar-sounding names. Even close matches can be grounds for rejection.

4

Submit with your incorporation filing

Include the NUANS report with your articles of incorporation. The name examiner makes the final call.

Ontario uses its own name search system through ServiceOntario. The process is similar but uses the province’s own database.

Common naming mistakes

  1. Using restricted words — Words like “bank,” “university,” “cooperative,” or “royal” require special approval or are outright prohibited
  2. Too similar to existing businesses — Even if not identical, names that could cause confusion will be rejected
  3. Forgetting bilingual requirements — Federal corporations can register names in English, French, or both — but you may need both for certain industries
  4. Not checking trademarks — A NUANS search covers some trademarks, but also check the Canadian Intellectual Property Office database
  5. Choosing a name that limits growth — “Toronto Lawn Care” works until you expand to Vancouver

Protecting your business name

Registration alone doesn’t give you exclusive rights to your name across Canada. Here’s the protection hierarchy:

MethodScopeCost
Provincial registrationProvince only$60–$300
Federal incorporationNational name protection$200
Trademark registrationNational, legal protection~$336+ per class

For the strongest protection, consider trademarking your business name through CIPO. This gives you legal recourse if someone else uses a confusingly similar name.
