Choosing a business name feels like the fun part of starting a company — until you find out your first choice is already taken, or worse, already trademarked by someone else. Here's how business name clearance actually works in Canada, and how to avoid the common mistakes.
Three Different Kinds of "Taken"
Most first-time founders assume there's one system that checks whether a name is available. In Canada, there are actually three separate, mostly unconnected systems, and clearing one doesn't mean you've cleared the others:
- Corporate/business name registries — checked via a NUANS Report or provincial Name Reservation. Confirms your name isn't identical or confusingly similar to another registered business or corporate name.
- Trademark registry — the Canadian Trademarks Database, maintained by the Canadian Intellectual Property Office. Checks for conflicts with legally registered trademarks — a separate legal concern from corporate name registration entirely.
- Common-law use — a business operating under a similar name in your market, even if never formally registered or trademarked, can still have legal rights to that name in the area where they've been using it. No search tool fully covers this — it's the residual risk that remains even after a clean NUANS and trademark search.
NUANS Report vs. Name Reservation
Which one you need depends on where you're registering. Federal incorporation and a handful of provinces — Ontario, Alberta, New Brunswick, Nova Scotia, and Prince Edward Island — use the NUANS (Newly Upgraded Automated Name Search) system, a $13.80 CAD report valid for 90 days — see our full guide to NUANS Reports for how the matching algorithm actually works. British Columbia runs its own name-approval process through BC Registry Services, separate from NUANS. Quebec, Manitoba, Saskatchewan, and the territories generally use a Name Reservation or pre-approval process through their own provincial registry instead. See our full name search service for the breakdown by jurisdiction.
Whichever system applies, the report only confirms your name passed a similarity check against existing registered names at the moment you searched — not that no one has any claim to it. It's a necessary step, not a guarantee.
Numbered Company vs. Named Corporation
If you incorporate, you can skip the name-search process entirely by registering as a numbered company — the government assigns you a number automatically (e.g., "1234567 Ontario Inc."), and you can still operate publicly under a trade name or brand without that name appearing on your legal registration. Many small corporations do exactly this: incorporate as a numbered company for simplicity, then register a separate trade name for public-facing branding. It's faster and avoids name-conflict delays, at the cost of a less polished-looking legal name on official documents.
What Makes a Name "Too Similar"?
NUANS and provincial name examiners look at more than exact matches — they flag names that sound similar, are spelled similarly, or could reasonably confuse the public about which business they're dealing with, even across different industries in some cases. A name search report typically comes back with a list of similar existing names and a similarity score; a human examiner at the registry ultimately decides whether your name is too close when they process your filing. This is why a name that looks clear to you on a quick internet search can still get flagged during formal registration.
Should You Also Run a Trademark Search?
If your business name is core to your brand — something customers will come to recognize and that you plan to build marketing around — a Trademark Search is worth the extra step, even though it's not required to register your business. Registering a business name only protects you within the corporate registry system; it does nothing to stop someone else from trademarking a similar name later and potentially forcing you to rebrand. A Trademark Search checks the existing landscape in the Canadian Trademarks Database before you invest in branding, signage, and marketing around a name.
A Practical Order of Operations
- Shortlist 2–3 name options before running any searches — your first choice often isn't available
- Run a Business Name Pre-Search for a quick, informal early check
- Once you've narrowed to a top choice, order the formal NUANS Report or Name Reservation required for your jurisdiction
- If the name is central to your brand, run a Trademark Search before investing in logos, signage, or marketing
- File your registration or incorporation using the cleared name
Frequently Asked Questions
How long is a NUANS Report valid?
90 days from the date it's issued. If your incorporation or registration isn't filed within that window, you'll need a new report.
Can two businesses have the same name in different provinces?
Sometimes, yes — provincial name registration only protects the name within that province. Federal incorporation is the only route that protects a name across all of Canada from the outset, which is one reason some businesses choose federal incorporation specifically for the stronger name protection, even if they operate mainly in one province.
What if my desired name is rejected?
You'll need to choose a different name, or a variation distinct enough to clear the similarity check, and re-run the search. This is why shortlisting a few options upfront saves time versus discovering a conflict after you've already committed to one name.
