How to Search for a Business Name in Canada
Run a business name search in Canada the right way: check federal, provincial and trademark records for business name availability before you register.
A business name search is the check you run before registering a name in Canada: you look through federal and provincial or territorial registries, and usually a trademarks database, to see whether someone already uses the name or one confusingly similar to it. It takes minutes online and it can save you a refused registration, a forced rebrand, or a dispute later. This guide explains what to search, where to search it, and how business name availability is judged today.
Why business name availability matters
In Canada, registering a name does not give you ownership of the words the way a trademark does, and a registry approval is not proof that nobody else holds rights to a similar name. What registration does is place your name on a public record and, in most provinces and territories, stop another business from registering an identical name in that jurisdiction. Checking business name availability first reduces the risk of a rejected application, a costly rebrand, or a complaint from a business that already trades under the name. It is also the cheapest part of the whole registration process.
Where to search: federal, provincial and territorial registries
There is no single national register containing every business name in Canada. Sole proprietorships and partnerships are registered provincially or territorially, while corporations may be federal or provincial, so a complete search of the business registry in Canada means checking more than one database. The table below shows the main sources.
| What you are checking | Where to search | What it covers |
|---|---|---|
| Federal corporation or federal trade name | Corporations Canada, through Canada.ca | National in scope; a NUANS report is generally required |
| Sole proprietorship, partnership or provincial company | Your provincial or territorial business or corporate registry | Names registered in that province or territory |
| Multi-jurisdiction lookup | Canada's Business Registries | Aggregated searching across participating registries |
| Trademarks | Canadian trademarks database (CIPO) | Registered and applied-for trademarks, not just business names |
| Domain names | Any domain registrar | Not a legal register, but important for branding |
Registry data is only as current as the filings behind it, and a name that is clear today can be taken next month, so search close to the date you actually register.
How to run a business name search step by step
- Write down the exact name you want plus two or three alternatives, so you are not stuck if the first choice is taken.
- Search your provincial or territorial registry for an exact match, then for names that sound or look similar.
- Repeat the search in other provinces or territories if you may expand or sell online across Canada.
- Check the Canadian trademarks database for conflicting marks, including marks in related product or service categories.
- Check domain availability and social media handles, since a name you cannot use online is rarely worth keeping.
- Save screenshots, dates and notes. They are useful if a conflict arises later or if a registry asks how you chose the name.
Trademarks, licences and other records to check separately
A registry search covers registered business names, not trademarks, which are handled by the Canadian Intellectual Property Office. A name can be clear at the registry yet still infringe someone's registered trademark, so a trademark search is worthwhile before you print signage or packaging. Municipal business licensing is separate again: many cities require a licence in the name you trade under, and a licence does not reserve the name against anyone else. If your province issues a Master Business Licence, treat that document as evidence of registration rather than proof of exclusive rights.
NUANS reports and name reservations
A NUANS report is a search of a national database of business names, corporate names and trademarks. Federal incorporation generally requires one, and several provinces require one for corporations. For a sole proprietorship, a full NUANS report is usually unnecessary, but some registries ask for a name search or a name reservation before you register, and a reservation holds the name for a limited period. Fee amounts and reservation periods vary by jurisdiction, so confirm the current requirement and cost with the registry you are dealing with. Our guide to the NUANS report in Canada explains when one is actually required.
What to do if the name is already taken
You normally cannot register an identical name, and many registries also refuse names that are confusingly similar to an existing registration. Options include:
- Choosing a different name entirely.
- Adding a distinctive word, such as a location or a made-up term.
- Narrowing the descriptive part of the name so it is clearly distinguishable.
- Checking whether the existing registration is in a different jurisdiction and line of business, which lowers but does not remove the risk.
- Asking the existing owner for written consent, where the registry permits that route.
- Getting trademark advice if the conflict involves a registered mark.
After the search: registering your name
Once the name is available, you register it with the registry that governs your business structure. A sole proprietorship is typically registered in the province or territory where you operate, and if you carry on business under your own legal name, some jurisdictions do not require registration at all. Understanding federal versus provincial registration helps you pick the right registry, and if you are starting out, review what a sole proprietorship is and how to register a business name in Canada before you file. Costs vary, so compare registration costs by province and confirm the current fee on your registry's website. This is general information, not legal or tax advice.
Frequently asked questions
How do I check if a business name is available in Canada?
Start with the registry that will handle your registration: your provincial or territorial business registry for a sole proprietorship, or Corporations Canada for a federal corporation. Then check broader sources such as Canada's Business Registries, the Canadian trademarks database and a domain registrar. Look for exact matches and for names that sound or look confusingly similar, and note the date of your search.
Do I need a NUANS report for a sole proprietorship?
Usually not. A NUANS report is a national search of business names, corporate names and trademarks, generally required for federal incorporation and by several provinces for corporations. A sole proprietorship registered in a province normally only needs the provincial name search that accompanies registration. Some registries still ask for a name search or reservation, so confirm the exact requirement where you plan to register.
Is a business name search free in Canada?
Basic searches are often free. Provincial and territorial registry databases generally allow free online lookups of registered names, and the Canadian trademarks database can be searched at no cost. Formal products such as a NUANS report or a name reservation usually carry a fee that varies by jurisdiction. Because amounts change, confirm the current cost on your provincial or territorial registry website or on Canada.ca.
What happens if the business name I want is already taken?
You generally cannot register an identical name, and registries may also refuse names that are confusingly similar to an existing registration. Your options include choosing a different name, adding a distinctive word, or seeking written consent from the existing owner where the registry allows it. If a registered trademark is involved, registration alone will not protect you, so a trademark search is worthwhile.
