What is a NUANS report?
A NUANS report is a search result comparing a proposed corporate name against a database of existing corporate names, business names, and registered trademarks across Canada. Both Corporations Canada and the Ontario Business Registry require one when you incorporate, or rename, a corporation with a word name, though a numbered company such as “1234567 Ontario Inc.” skips the search entirely since there is no name to check. A NUANS report is valid for 90 days from the search date, and it reduces the risk of a name conflict without fully guaranteeing your name is free of one.

What a NUANS report actually is
NUANS stands for the Newly Upgraded Automated Name Search system, and a NUANS report is the output of running your proposed corporate name through it. The report lists existing corporate names, registered business names, and trademarks that are identical or similar to what you are proposing, so you and the government registry can see whether your name conflicts with something already on file before the corporation is approved. It is a search result, not an approval or a rejection on its own; the registry examiner still makes the final call on whether your proposed name can proceed once your report is submitted with the rest of your filing.
When you actually need one
Both federal incorporation through Corporations Canada and provincial incorporation through the Ontario Business Registry require a NUANS report when you choose a word name for your corporation, such as "Maple Street Consulting Inc." rather than a number. Choosing a numbered company instead, where the government simply assigns the corporation a number followed by the jurisdiction and a legal ending, skips the name search step entirely, which is worth considering if the name itself is not central to your brand or customer-facing identity.
Not-for-profits need one too
A NUANS report is not just a business corporation requirement. Anyone incorporating a not-for-profit in Ontario with a word name goes through the same search process before the Ontario Business Registry will approve the articles, and a not-for-profit can choose a numbered corporation to skip it in exactly the same way a business can. The three-part name structure and the conflict-checking logic described below apply identically whether the entity behind the name is a for-profit business or a charitable organization.
How long a report stays valid
A NUANS report is valid for 90 days from the date it was generated. If you do not complete your incorporation, or your name change, within that window, you generally need to run a new search before the registry will accept the filing, since the underlying name database can change in the meantime as other corporations and trademarks get registered.
What the search is actually checking
A corporate name has three parts: a distinctive element that makes it unique, a descriptive element that describes the business, and a legal element such as Inc., Corp., or Ltd. The NUANS search flags names that are identical or confusingly similar to existing ones, particularly where the distinctive element overlaps, since a name too close to an existing corporation's can be refused at the registry or challenged by the other business afterward, even if the initial filing goes through.
A name built on a purely descriptive element with little or nothing distinctive about it, such as "Ontario Home Renovations," is harder to clear than one with a genuinely unique word or combination attached to it, since a descriptive name is more likely to already be in use by several other similar businesses across the province. Owners who want a strong, defensible name generally do better picking a distinctive element that says something about the business without simply describing the industry it operates in.
Where to get one and what it costs
NUANS reports are available through a self-serve search directly, and through third-party search houses that also review the result for you as part of the fee. Pricing varies by source and has ranged, as at the time of writing, from roughly the mid-teens for a basic self-serve search up to considerably more through a full-service provider; confirm current pricing with whichever source you use before you budget for it, since this is not a government-set fee. This is a separate charge from the incorporation filing fee itself; see our cost to incorporate in Ontario breakdown for how it fits alongside the government fee and any professional fees.
A search house typically charges more than a bare self-serve report because it also reviews the results and flags anything that looks like a genuine conflict rather than leaving you to interpret a raw list of similar names yourself. For a first-time incorporator, that review is often worth the extra cost, since misreading a borderline result and filing anyway can mean a rejected application and a second round of fees to fix it.
A clean report is not a full guarantee
A NUANS report that comes back clean improves your odds of approval, but it does not amount to a legal clearance the way a trademark search and opinion would. The report only searches names and trademarks that are actually registered or on file; it will not catch an unregistered trade name already in active use in the marketplace, and someone using that name first can still raise a dispute with you later even though your NUANS report came back clear. Owners who care deeply about the name should consider a separate trademark search alongside the NUANS report, rather than treating the incorporation search as the final word on availability, especially if the name is going to carry real marketing investment behind it over time.
How we handle this
We run the NUANS search as part of every named incorporation we handle, and we flag a borderline result before filing rather than after a rejection comes back from the registry. This is part of our incorporation and compliance service, alongside the rest of the filing, whether you are naming a standard business corporation or a not-for-profit.

Do I need a NUANS report for a numbered company?
No, a numbered company such as "1234567 Ontario Inc." skips the name search entirely, since the government assigns the number rather than checking a proposed word name.
Does a NUANS report protect my business name like a trademark would?
No, it only reduces the risk that the government refuses your name at incorporation; actual trademark protection is a separate and more thorough legal process.
What happens if my NUANS report shows a similar existing name?
You can often still proceed if the similarity is minor, sometimes with consent from the existing name holder or a small change to your distinctive element, but a close match raises the risk of a refusal or a dispute later.
