What Is a NUANS Report?
A NUANS Report is an official name search report used for certain corporate filings in Canada.
For Ontario corporations, the report compares your proposed corporation name against names contained in the NUANS database, including existing corporate names, business names, and certain trademarks.
The purpose is to identify names that may be identical or confusingly similar to your proposed name.
A NUANS reservation report reserves the proposed corporate name in the NUANS database for 90 days, but it does not constitute government approval of the name.
In other words:
- NUANS reservation: Yes
- Government name approval: No
- Trademark ownership or protection: No
A NUANS Report should therefore be understood as both a name search and reservation report, not as a government certificate approving your corporation name.
What Does NUANS Stand For?
NUANS stands for Newly Upgraded Automated Name Search.
It is a computerized name-search system developed for Canadian corporate name searches.
Rather than checking only for exact matches, the system analyzes names for similarities such as:
- Spelling
- Pronunciation
- Appearance
- Distinctive words
- Descriptive words
- Business identifiers
- Legal endings
This helps identify existing names that could potentially be confused with the proposed corporation name.
Do I Need a NUANS Report to Incorporate in Ontario?
If you are incorporating an Ontario corporation using a custom corporation name, an Ontario-biased or weighted NUANS Report is generally required as part of the incorporation process.
A NUANS Report may also be required for other Ontario corporate filings involving a proposed corporation name, including certain:
- New incorporations
- Corporation name changes
- Revivals involving a new name
- Extra-provincial filings
- Other corporate filings that require a name search
The NUANS Report used for the filing must generally be dated within the applicable 90-day period.
If you are incorporating a corporation such as:
Maple Horizon Technologies Inc.
you would normally obtain an Ontario NUANS Report for that proposed name before completing the applicable filing.
When Is a NUANS Report Not Required?
A NUANS Report is generally not required when incorporating a numbered Ontario corporation.
For example:
12345678 Ontario Inc.
Because the corporation number is assigned through the incorporation process, there is no proposed distinctive corporation name to search.
A NUANS Report may also be unnecessary for filings that do not involve adopting or changing a corporation name.
Requirements depend on the type of filing being submitted, so it is important to confirm the requirements for your particular transaction.
Does a NUANS Report Reserve My Business Name?
A NUANS reservation report reserves the proposed corporate name in the NUANS database for 90 days.
However, reservation does not mean that the corporation name has been approved by the Ontario government.
It also does not:
- Guarantee that the incorporation will be accepted
- Give you ownership of the name
- Create trademark rights
- Prevent every other business from using a similar name
The distinction between reservation and approval is important.
NUANS reserves the proposed name in its database for the applicable period, while the government registry retains responsibility for the corporate filing itself.
Does a NUANS Report Guarantee Name Approval?
No.
A NUANS Report is not a certificate of government approval.
The report provides information about potentially similar names and reserves the proposed corporate name in the NUANS database for 90 days.
However, obtaining the report does not guarantee that your corporation name will ultimately be accepted as part of a government filing.
For example, problems may still arise if the proposed name:
- Conflicts with applicable naming rules
- Creates a misleading impression
- Contains restricted or prohibited wording
- Is too similar to another name in circumstances that create legal concerns
The NUANS Report is therefore an important part of the process, but it is not the final approval decision.
How Does the NUANS Search Work?
When you submit a proposed corporation name, the NUANS system compares it against records contained in the NUANS database.
These may include:
- Ontario corporations
- Federal corporations
- Business names
- Certain registered trademarks
- Other names contained within the NUANS database
The system looks for similarities rather than only exact matches.
For example, if your proposed corporation name is:
Maple Leaf Consulting Inc.
the report may identify names such as:
- Maple Leaf Business Solutions Inc.
- Maple Consulting Group Inc.
- Maple Leaf Advisors Ltd.
- Maple Consulting Services Corp.
The purpose of these results is to help identify names that may be similar enough to warrant further consideration.
Seeing similar names on your report does not automatically mean that your proposed name will be rejected.
What Information Appears on a NUANS Report?
A typical Ontario NUANS Report includes information such as:
- Proposed corporation name
- NUANS search reference number
- Report date
- Reservation or expiry information
- Similar corporate names
- Similar business names
- Certain trademark references
- Jurisdiction information
The number of search results can vary significantly.
A highly distinctive proposed name may produce relatively few similar results, while a name containing common words may produce many pages of matches.
How Long Is an Ontario NUANS Report Valid?
An Ontario NUANS Report is generally valid for 90 days from the date of the report.
During this period, the proposed corporate name is reserved in the NUANS database.
If the required corporate filing is not completed before the report expires, a new NUANS Report will generally be required.
For this reason, it usually makes sense to order your NUANS Report when you are reasonably close to completing your incorporation or other corporate filing.
How Long Does It Take to Get a NUANS Report?
Processing time depends on the NUANS provider.
Some providers process reports manually during business hours, while automated services can generate and deliver reports much faster.
With GetNuans, Ontario NUANS Reports are processed automatically and are typically delivered electronically within minutes, 24 hours a day.
This means you can order a report:
- During regular business hours
- In the evening
- Overnight
- On weekends
- On holidays
Once completed, the official report is delivered electronically as a PDF.
How to Order an Ontario NUANS Report
Ordering an Ontario NUANS Report online is straightforward.
You will typically need to provide:
- Your proposed corporation name
- Ontario as the jurisdiction
- The required legal ending, where applicable
- Your contact information
- Payment
Before submitting the order, carefully check the spelling of the proposed corporation name.
For example:
Northstar Robotics Inc.
is different from:
North Star Robotics Inc.
Your NUANS Report should reflect the corporation name you actually intend to use for the filing.
Should I Include Inc., Ltd. or Corp.?
Ontario corporation names normally contain a legal ending or legal designation.
Common examples include:
- Inc.
- Incorporated
- Corp.
- Corporation
- Ltd.
- Limited
For example:
Aurora Robotics Inc.
The legal ending should match the corporation name you intend to use.
Avoid accidentally entering the legal ending twice.
For example:
Aurora Robotics Inc. Inc.
would be incorrect.
If an ordering form provides a separate field for the legal ending, enter the distinctive portion of the business name in the name field and select the appropriate legal ending separately.
Tips for Choosing a Strong Corporation Name
Choosing a distinctive name can reduce the likelihood of confusion with existing businesses.
Use a distinctive element
Names built entirely from common descriptive terms tend to produce more similar search results.
Compare:
Ontario Technology Services Inc.
with:
Velmora Technology Services Inc.
The invented or distinctive word makes the second name easier to distinguish.
Avoid names that closely resemble established businesses
Changing only one generic word may not make a proposed name meaningfully different.
Consider trademarks separately
A NUANS Report may contain certain trademark references, but it is not a comprehensive trademark clearance search.
If the name will become an important brand, consider whether separate trademark research or professional advice is appropriate.
Check the domain name
If your corporation will operate online, check whether an appropriate .ca or .com domain is available.
Think about future growth
A very narrow name may become limiting if the company later expands into different products, services, or geographic markets.
Common NUANS Mistakes to Avoid
Assuming reservation means government approval
This is one of the most common misunderstandings.
A NUANS reservation report reserves the proposed corporate name in the NUANS database for 90 days.
However, the reservation does not mean that the name has been approved by the applicable government registry.
Waiting until the report expires
Ontario NUANS Reports are generally valid for 90 days.
If you wait too long before completing the corporate filing, you may have to obtain another report.
Ordering the wrong jurisdiction
NUANS Reports are jurisdiction-specific.
If you are incorporating an Ontario corporation, make sure you are ordering the appropriate Ontario NUANS Report rather than a report intended for another jurisdiction.
Entering the corporation name incorrectly
Check:
- Spelling
- Spaces
- Punctuation
- Distinctive wording
- Legal ending
before submitting your order.
Your report should reflect the corporation name you intend to use.
Assuming similar results automatically mean rejection
A NUANS Report commonly contains similar names.
Their presence does not automatically mean that your proposed corporation name cannot be used.
The report provides information for the applicable filing and review process.
Treating NUANS as a complete trademark search
A NUANS Report and a comprehensive trademark clearance search are not the same thing.
If trademark protection is important to your business, consider conducting additional trademark research.
Frequently Asked Questions
Is a NUANS Report mandatory in Ontario?
For many Ontario corporate filings involving a proposed custom corporation name, an Ontario-biased or weighted NUANS Report is required.
A numbered Ontario corporation generally does not require a NUANS name search.
Do I need a NUANS Report for a numbered corporation?
Generally, no.
If you are incorporating using a corporation number assigned through the incorporation process, such as:
12345678 Ontario Inc.
a NUANS Report is generally unnecessary because there is no proposed distinctive corporation name to search.
Does a NUANS Report reserve my corporation name?
Yes.
A NUANS reservation report reserves the proposed corporate name in the NUANS database for 90 days.
However, this reservation does not constitute government approval of the name and does not create trademark ownership or exclusive rights to the name.
Does a NUANS Report mean my corporation name is approved?
No.
NUANS reservation and government approval are separate concepts.
The report reserves the proposed name in the NUANS database and provides search results, but it does not guarantee that the applicable government filing will be accepted.
How long is an Ontario NUANS Report valid?
An Ontario NUANS Report is generally valid for 90 days from the report date.
If it expires before the applicable corporate filing is completed, a new report will generally be required.
How quickly can I get an Ontario NUANS Report?
Processing times depend on the provider.
GetNuans processes Ontario NUANS Reports automatically, with reports typically delivered electronically within minutes, 24/7.
Can I get a NUANS Report at night or on a weekend?
Yes.
Automated NUANS providers such as GetNuans can process reports outside normal business hours.
GetNuans accepts and processes Ontario NUANS orders 24 hours a day, including evenings and weekends.
Can I use the same NUANS Report more than once?
A valid NUANS Report is intended for the proposed name and filing for which it was obtained.
Whether it can be reused depends on the circumstances and filing requirements.
If the report has expired or the proposed corporation name changes, a new report will generally be required.
What if I change my corporation name after ordering the report?
If the proposed corporation name changes, you may need a new NUANS search reflecting the new name.
For example, a report ordered for:
Aurora Robotics Inc.
does not automatically become a report for:
Aurora Automation Inc.
Check the proposed name carefully before ordering.
What happens if my proposed name is rejected?
If the proposed corporation name cannot be used for the filing, you may need to choose a different name and obtain a new NUANS Report for the replacement name.
Can two Ontario corporations have similar names?
Similar names can appear in the NUANS database.
Whether a particular proposed name can be used depends on the applicable corporate naming rules and circumstances.
A NUANS search is designed to identify these potentially similar names so they can be considered before the filing is completed.
Is a NUANS Report the same as a trademark search?
No.
A NUANS Report may contain certain trademark references, but it is not a comprehensive trademark clearance search.
Businesses planning to invest significantly in a brand should consider whether additional trademark research or professional advice is appropriate.
Can I use a Federal NUANS Report for an Ontario incorporation?
Ontario filings that require a NUANS search generally require the appropriate Ontario-biased or weighted NUANS Report.
A NUANS Report prepared for another jurisdiction should not automatically be assumed to satisfy Ontario filing requirements.
Final Thoughts
A NUANS Report is an important part of incorporating a named corporation in Ontario.
It performs two important functions:
- It searches the NUANS database for potentially similar names.
- It reserves the proposed corporate name in the NUANS database for 90 days.
However, a NUANS reservation is not the same as government approval, and a NUANS Report does not create trademark ownership or guarantee that a corporate filing will be accepted.
Understanding these distinctions can help you avoid unnecessary delays and order the correct report for your Ontario corporation.
