Choosing a business name in Canada involves both practical branding considerations and legal restrictions. This guide covers what names are allowed, what to avoid, how to verify availability, and how to protect a name you care about.
The Basic Rule: Your Name Must Be Distinctive
In every Canadian province, a business name must be sufficiently different from existing registered names. The exact standard varies — Ontario uses a “clearly distinguishable” test, while BC uses a more detailed name approval process — but the principle is the same: your name cannot so closely resemble an existing business name that it would confuse the public.
Restricted and Prohibited Words
Certain words are restricted or prohibited in Canadian business names at the provincial and federal level:
- Financial institution terms: “Bank,” “Trust,” “Credit Union,” “Insurance” — require regulatory approval from OSFI or provincial financial regulators
- Government and royal references: “Royal,” “Crown,” “Canada,” “National,” “Federal,” “Government” — restricted; require approval
- Professional designations: “Lawyer,” “Doctor,” “Accountant,” “Engineer,” “Architect” — only permitted if the business is operated by a licensed professional in that field
- Corporate identifiers on sole proprietorships: “Inc.,” “Ltd.,” “Corp.,” “Incorporated,” “Limited” — only permitted if the entity is actually incorporated
Good Naming Principles for Canadian Businesses
Be Specific About What You Do
Generic names like “Canadian Business Solutions” or “Professional Services Group” are harder to protect (less distinctive), harder to search for online, and tell potential clients nothing. A name like “Maple Road Bookkeeping” or “Clearwater Immigration Consulting” communicates your field immediately.
Think About Search Engine Visibility
If local clients find you through Google, your business name or a close variation of it should appear in searches. “Vancouver Wedding Photography by Sophie Chen” is more searchable than “SophPhoto Studio.”
Check the .ca Domain
Before committing to a name, verify that a corresponding .ca domain is available (or at least a close variant). Canadian clients expect a .ca domain for Canadian businesses. Check availability at cira.ca.
Keep It Pronounceable and Memorable
Referrals are important in Canadian business networks. If clients cannot easily say your business name out loud, referrals suffer. Avoid creative spellings, numbers substituting for words, or names that require explanation.
How to Check Name Availability
Provincial Registry Search
Each province has an online search tool:
- Ontario: ontario.ca/businessregistry — search the registry before applying
- BC: BC Registry name request portal (bcregistry.gov.bc.ca)
- Alberta: NUANS search through an authorized registry agent
- Other provinces: Provincial corporate registry search tools
NUANS Search (for Federal Incorporation or Provinces That Require It)
NUANS (Newly Upgraded Automated Name Search) is the national corporate name database. It costs approximately $13.80 for a federal NUANS report. Some provinces (Alberta, Saskatchewan, Manitoba) require a NUANS search for business name registration. Ontario and BC do not use NUANS for sole proprietorships — they have their own provincial search systems.
Trademark Database
A registered business name does not protect you from trademark infringement. Search the Canadian Trademarks Database (ised.canada.ca/cipo/cptrademarks) to verify your intended name is not already trademarked. This is especially important for product-based businesses or brands you plan to grow.
Internet Search
A business name can be free in the provincial registry but still be in common use by an unregistered business or a US company operating in Canada. Search Google, LinkedIn, and Facebook for your intended name before committing.
Protecting Your Business Name
Provincial registration does not give you exclusive rights to a name — it only creates a public record of your use. Another business can register a similar name in the same province.
Options for stronger protection:
- Incorporation: A corporate name is protected within the province of incorporation (provincial) or nationally (federal). No other corporation can register the same or confusingly similar name.
- Trademark: A registered trademark gives you exclusive right to use a name (or logo) in connection with specific goods or services across Canada. Filing fees start at $458.28 for one class of goods/services. Processing takes 18–24 months. Visit the CIPO trademark portal at ised.canada.ca/cipo/cptrademarks to apply.
Frequently Asked Questions
Can two businesses have the same name in Canada?
Yes — for sole proprietorships. Provincial business name registration does not guarantee exclusive rights. Two businesses can register similar names in the same province, which is why trademark registration provides stronger protection if your name is commercially valuable.
Can I use my name plus a descriptor, like “John Smith Photography”?
Yes. This is a common and valid approach. You would register “John Smith Photography” as your business name (since it differs from your legal name “John Smith”). No name search issues arise as long as no one else has registered “John Smith Photography” in your province.
What if my business name is already taken?
If the exact name is taken, the registry will reject your application. Options: choose a different name, add a geographic modifier (“Toronto” or your city name), add a distinctive word, or incorporate with a numbered company and operate under a trade name.
