How to Do a Business Name Search in Canada

A captivating business name is crucial, and it does a lot of work. It builds brand awareness, drives customer loyalty and sales, and helps you attract talent when it’s time to hire. It goes on your marketing materials, contracts, invoices, and your certificate of insurance.

A business name search in Canada is really four separate searches, plus one paid report if you’re incorporating. Here’s the sequence to follow:

1. Start With a Free Preliminary Search

Before you pay for anything, run your top two or three name ideas through a quick informal check: 

• A plain Google search. Fast, free, and it’ll catch the obvious conflicts.
• Domain availability. If the .ca and .com are both gone and there’s no workable alternative, that’s a problem you’ll live with for years.
• Social handles. Check Instagram, Facebook, LinkedIn, TikTok, X/Twitter and other social networks you intend to use before you commit. Inconsistent handles across platforms make you harder to find.

One caution: a Google search only surfaces the slice of registered Canadian businesses that have an online presence. Plenty of registered companies don’t. Treat this step as a sanity check, not a clearance.

Pro tip: Come up with a shortlist, not a favourite. Even a name you’re certain about might already be taken, and having three viable options saves you from starting over.

2. Search Your Provincial Registry

Every province maintains a public registry of business names and corporations. This is where you’ll find the registrations that never show up on Google.

Rules and name availability differ between jurisdictions, so if you plan to operate in more than one province, search each one:

• Alberta
• British Columbia
• Manitoba
• New Brunswick
• Newfoundland and Labrador
• Nova Scotia
• Ontario
• Prince Edward Island
• Quebec
• Saskatchewan

Most of these searches are free and take under a minute. In Ontario, for example, the Ontario Business Registry lets you check name availability at no cost before you register anything. 

3. Search Corporation Canada‘s Federal Database

Provincial registries won’t show you federally incorporated companies. Corporations Canada maintains a free, searchable database of every federal corporation in the country. A federally incorporated business can operate in your province using a name your provincial registry shows as available.

Skip this step, and you can register a name that puts you in direct conflict with a company already operating down the street.

4. Do a Free CIPO Trademark Search

This is the step almost everyone skips, and it’s the one that bites. A business name and a trademark are two different things.

A business name is a name your business operates under. A trademark is one or more words, designs, or sounds that distinguish your business from everyone else‘s, and it carries far more legal weight. 

Here’s why that matters: a registered trademark can stop you from using a name even if your provincial registry approves your registration. Registry approval isn’t legal permission to use a name. It just means nobody else registered that exact name in that jurisdiction first.

Search the Canadian Intellectual Property Office’s (CIPO) Canadian Trademarks Database. It’s free to use.

On trademark rights: Registration is what gives you exclusive rights to the name across Canada for 10 years, renewable after that.

5. Order Your Official Name Search Report

If you’re incorporating, the free searches aren’t enough. You need a formal name search report to file with your application. Which report you need depends on where you’re incorporating. 

NUANS covers six jurisdictions

NUANS (Newly Upgraded Automated Name Search) is the Government of Canada’s official business name and trademark search tool. It scans corporate names and trademarks across the country and returns a list of everything similar or identical to the name you want. NUANS applies to:

• Canada (federal)
• Ontario
• Alberta
• New Brunswick
• Nova Scotia
• Prince Edward Island

Five provinces use their own systems

British Columbia, Quebec, Manitoba, Saskatchewan, and Newfoundland and Labrador don’t use NUANS. Each runs its own name request or name reservation system through its provincial registry, and that’s the report you’ll need to file.

What it costs and how long it lasts

A federal name search runs around $13.80, and it’s built directly into most Canada Business Corporations Act online incorporation applications. In most cases, that means you shouldn’t buy a separate report before filing because the search happens as part of the application. Third-party search agents typically charge $20 to $40 if you’d rather order one independently.

Your report is generally valid for 90 days from the date it’s generated. File within that window or you’ll need a fresh one.

The report doesn’t approve your business name

Your report gets submitted alongside your articles of incorporation, and a federal or provincial examiner reviews it to confirm your name doesn’t conflict with an existing business. If there is a conflict, they’ll want documentation explaining why you submitted it anyway.

Sole proprietors, take note: you don’t need a NUANS report at all. Since a sole proprietor’s business name isn’t protected the way a corporate name is, the report isn’t mandatory. However, a preliminary search is still strongly recommended.

6. Register Your Business Name

What you register depends on your business structure. Is it a sole proprietorship, partnership, or corporation?

Sole proprietor operating under your own legal name? You generally don’t need to register a business name at all.

Sole proprietor or partnership operating under any other name? You register that name as a business or trade name with your province. In Ontario, that’s around $60 online filing through the Ontario Business Registry, and the registration is valid for five years before it needs renewing. If you operate under an unregistered name, you may face fines, and you’ll have trouble opening a business bank account or enforcing contracts.

Incorporating? Your corporate name gets registered as part of your articles of incorporation. Incorporate provincially, and you get exclusive use of that name in that province. Incorporate federally, and you get exclusive use across Canada.

Don’t want to deal with a name search at all? You can incorporate as a numbered company, such as 1234567 Ontario Inc., and register a trade name separately whenever you’re ready. It’s a common move for founders who want to file fast and settle on branding later.

Two more things to handle after registering

Get a Canada Revenue Agency (CRA) Business Number, which is free and required for payroll, HST, and most other tax accounts. Then register for HST once your annual revenue passes $30,000. Registration itself is free.

Some municipalities also require a local business licence on top of your provincial registration, so check with your city before you open the doors.

How to Choose a Business Name

A few things to weigh before you fall in love with an idea:  

• Make it relevant. Choose a name that clearly signals what you sell and appeals to the customers you want. 

• Aim for clarity and simplicity. Your name is your first impression. Easy to say, easy to spell, easy to remember. A name that rolls off the tongue gets shared in conversation, recommended to others, and typed correctly into a search bar. 

• Be distinctive. A unique name sets you apart from competitors and lowers your legal risk. Generic names are harder to protect and harder to rank. 

• Keep it short. Shorter names are easier to rank in search engines and AI search tools, and they make for a cleaner domain and URL. 

• Have backups. Three options minimum. Your favourite might be gone. 

Rules that get business names rejected

Corporate names in Canada need three parts:

1. A distinctive element: the coined or unique part
2. A descriptive element: what you actually do
3. A legal element: Inc., Ltd., Corp., or Limited

Some words are restricted. Your name can’t imply a connection to a government, and it can’t use words suggesting a regulated activity, like “bank“, “trust“, “insurance“, “engineering“, and similar without authorization from the relevant regulator. It also can’t be obscene.

Business Names, Trademarks, Patents and Copyright: What’s the Difference?

Four different protections, four different scopes. Here’s how they compare: 

The takeaway: registering a business name is not the same as owning it. Only a trademark gives you exclusive national rights. 

What Insurance Protects Your Intellectual Property (IP)?

Intellectual property insurance can help you or your business mount a defence if your trademarks, patents, or copyrights are infringed. Coverage can include lost profits and the loss of your IP rights.

Frequently Asked Questions About Business Name Searches in Canada

How do I check if a business name is already taken in Canada? 

Search three free databases: your provincial or territorial business registry, Corporations Canada’s federal corporations database, and the CIPO Canadian Trademarks Database. All three are free and take minutes. A Google search alone isn’t enough. It only surfaces registered businesses that have an online presence. 

Is a business name search free in Canada? 

The preliminary searches are free. Provincial registries, the federal corporations database, and the CIPO trademarks database all cost nothing to search. What costs money is the official name search report you need to file an incorporation. A federal name search is $13.80, and third-party agents typically charge $20 to $40. 

What is a NUANS report and do I need one? 

A NUANS report is the Government of Canada’s official business name and trademark search. It lists existing corporate names and trademarks similar or identical to the name you want. You need one if you’re incorporating federally or in Ontario, Alberta, New Brunswick, Nova Scotia, or Prince Edward Island. Sole proprietors don’t need one, though a preliminary search is still smart. British Columbia, Quebec, Manitoba, Saskatchewan, and Newfoundland and Labrador use their own provincial name search systems instead. 

Do sole proprietors have to register a business name in Canada? 

Not if you operate under your own legal name. The moment you use any other name you have to register it as a business or trade name with your province. In Ontario, that’s a $60 online filing, valid for five years. 

Does registering a business name protect it? 

Only within that jurisdiction, and only against identical registrations. Provincial registration doesn’t stop a business in another province from using your name, and it doesn’t protect you against a registered trademark holder. A trademark is the only thing that gives you exclusive rights to a name across Canada. 

Do I need insurance before I register my business name? 

No, but you’ll likely need it before you sign your first contract. Many clients, landlords, and general contractors require proof of commercial general liability coverage, and the certificate of insurance they ask for lists your registered business name. Getting the name and the coverage sorted together saves you re-issuing documents later.
