Should I Include Inc., Ltd. or Corp. on My Ontario NUANS Report?
August 31, 2026
If you're ordering an Ontario NUANS Report, you may be wondering whether your proposed corporation name should include a legal ending such as Inc., Ltd. or Corp.
The short answer is:
Yes. Ontario requires the legal designation to be included on the NUANS Report.
For example, if the corporation you intend to incorporate is:
Silverline Studios Inc.
your Ontario NUANS Report should reflect the proposed corporation name with the appropriate legal ending.
If the NUANS ordering form has a separate Legal Ending field, however, you should normally enter:
Business name: Silverline Studios
Legal ending: Inc.
and not:
Business name: Silverline Studios Inc.
Legal ending: Inc.
Otherwise, you could accidentally create:
Silverline Studios Inc. Inc.
This guide explains how legal endings work on Ontario NUANS Reports and how to avoid some of the most common ordering mistakes.

What Is a Legal Ending?
The legal ending, sometimes called the legal element or legal designation, is the part of a corporation name that identifies it as an incorporated entity.
Common examples include:
- Inc.
- Incorporated
- Corp.
- Corporation
- Ltd.
- Limited
For example:
Northstar Robotics Inc.
can be broken down into:
| Part | Example |
|---|---|
| Distinctive element | Northstar |
| Descriptive element | Robotics |
| Legal element | Inc. |
The legal ending is part of the corporation's legal name.
Does an Ontario NUANS Report Need Inc., Ltd. or Corp.?
Yes.
Ontario is one of the jurisdictions that requires the legal designation to appear on the NUANS Report.
This means that if your intended corporation name is:
Qavellis Robotics Inc.
the proposed corporate name on the Ontario NUANS Report should include the appropriate legal element.
The legal ending is different from the distinctive term used to help focus the NUANS search.
In:
Qavellis Robotics Inc.
the likely elements would be:
Distinctive term: Qavellis
Descriptive element: Robotics
Legal ending: Inc.
Which Legal Endings Can an Ontario Corporation Use?
For an Ontario business corporation, common English legal endings include:
- Inc.
- Incorporated
- Corp.
- Corporation
- Ltd.
- Limited
For example:
Northern Peak Technologies Inc.
or:
Northern Peak Technologies Corporation
The abbreviated and full versions represent the legal element of the corporation name.
When ordering your NUANS Report, choose the legal ending that you actually intend to use for the corporation.
Should I Type "Inc." in the Business Name Field?
It depends on how the ordering form is designed.
If you are asked to enter the complete proposed corporation name in a single field, you may enter:
Silverline Studios Inc.
However, if the form provides:
Business Name
and a separate:
Legal Ending
field, enter the name without the ending in the first field.
For example:
Correct:
Business Name: Silverline Studios
Legal Ending: Inc.
The system can then construct:
Silverline Studios Inc.
What If the Form Has a Separate Legal Ending Field?
When the legal ending is selected separately, do not normally type it again into the business name field.
For example:
Correct
Business Name: Aurora Robotics
Legal Ending: Corp.
Result:
Aurora Robotics Corp.
Incorrect
Business Name: Aurora Robotics Inc.
Legal Ending: Corp.
This creates a conflict between:
Inc.
and:
Corp.
It is unclear whether the intended corporation name is:
Aurora Robotics Inc.
or:
Aurora Robotics Corp.
The safest approach is to enter the main portion of the proposed name once and select the intended legal ending separately.
What If My Business Name Already Includes "Inc."?
This is a common ordering mistake.
Suppose you enter:
Silverline Studios Inc.
in the Business Name field, but the form also asks you to select:
Inc.
as the Legal Ending.
You should normally remove Inc. from the Business Name field and leave:
Silverline Studios
Then select:
Inc.
from the Legal Ending field.
The completed proposed name remains:
Silverline Studios Inc.
You are not removing Inc. from the corporation name.
You are simply avoiding entering the same legal ending twice.
What If the Legal Ending in My Business Name Is Different From the One I Selected?
This should be corrected before ordering the report.
For example:
Business Name: Qavellis Robotics Inc.
Selected Legal Ending: Corp.
creates two different possible names:
Qavellis Robotics Inc.
and:
Qavellis Robotics Corp.
Before continuing, decide which legal name you actually intend to use.
If the intended name is:
Qavellis Robotics Inc.
enter:
Business Name: Qavellis Robotics
Legal Ending: Inc.
If the intended name is:
Qavellis Robotics Corp.
enter:
Business Name: Qavellis Robotics
Legal Ending: Corp.
Do not rely on the NUANS provider to guess which one you intended.
What If I Choose the Wrong Legal Ending by Mistake?
If you notice the mistake before the NUANS Report is generated, correct the order before submitting it.
If the report has already been issued, review the proposed corporate name shown on the report.
Your NUANS Report should correspond to the corporation name you intend to use for the Ontario filing.
If the report says:
Northstar Robotics Inc.
but you actually intend to incorporate:
Northstar Robotics Corp.
do not simply assume the existing report will be appropriate for the filing.
Contact the NUANS provider or confirm the applicable filing requirements before proceeding.
This is especially important because Ontario requires the legal designation to appear on the NUANS Report.
Does Inc. vs. Corp. Affect the NUANS Search?
The legal ending is part of the proposed corporation name, but it normally does not provide the distinctive identity of the business.
For example:
Velmora Consulting Inc.
and:
Velmora Consulting Corp.
both share the same important distinctive and descriptive wording:
Velmora Consulting
The NUANS system is primarily concerned with identifying potentially confusing names, and legal designations such as Inc. or Corp. do not normally make a proposed name meaningfully distinctive.
However, Ontario requires the legal designation to appear on the NUANS Report, so you should still select the legal ending you intend to use.
Is Inc. the Same as Incorporated?
Inc. is the abbreviated form of Incorporated.
Similarly:
- Corp. = Corporation
- Ltd. = Limited
Ontario's Business Corporations Act recognizes both full and abbreviated forms of these legal elements.
For example:
Aurora Technologies Incorporated
may use the full legal element, while:
Aurora Technologies Inc.
uses its abbreviated form.
When ordering your report, use the version that matches the proposed corporation name you intend to file.
Is Inc. Better Than Corp. or Ltd.?
For ordinary naming purposes, one is not inherently "better" than another.
The choice is primarily part of how you want the legal corporation name to appear.
For example:
Aurora Technologies Inc.
Aurora Technologies Corp.
Aurora Technologies Ltd.
all use different legal endings.
The important point for your NUANS order is to choose the one you actually intend to use and enter it consistently.
Does the Legal Ending Make My Name More Distinctive?
Generally, no.
Adding a different legal ending does not normally turn an otherwise confusingly similar name into a strongly distinctive one.
For example:
Velmora Consulting Inc.
and:
Velmora Consulting Corp.
still contain the same core name:
Velmora Consulting
The distinctive part of the corporation name is generally something such as:
Velmora
rather than:
Inc.
or:
Corp.
If you're unsure what counts as the distinctive portion of your name, see our guide:
What Is the Distinctive Term on a NUANS Report?
Can I Incorporate Without Inc., Ltd. or Corp.?
A named Ontario business corporation normally requires an appropriate legal element in its corporate name.
Examples include:
Incorporated
Inc.
Corporation
Corp.
Limited
Ltd.
So a proposed corporation name such as:
Northstar Robotics
would normally need an appropriate legal ending for the corporate name, such as:
Northstar Robotics Inc.
This is different from a registered business name, trade name, or operating name, which follows different rules.
Do Numbered Ontario Corporations Need a NUANS Report?
Generally, no.
If you incorporate a numbered Ontario corporation, a corporation number is assigned as part of the incorporation process.
For example:
12345678 Ontario Inc.
Because you are not proposing a distinctive corporation name such as:
Northstar Robotics Inc.
a NUANS name search is generally unnecessary.
Common Mistakes When Entering a Legal Ending
Entering the ending twice
For example:
Business Name: Silverline Studios Inc.
Legal Ending: Inc.
which could produce:
Silverline Studios Inc. Inc.
Entering one ending but selecting another
For example:
Business Name: Silverline Studios Inc.
Legal Ending: Corp.
Now it is unclear whether you want:
Silverline Studios Inc.
or:
Silverline Studios Corp.
Leaving out the legal ending entirely
For an Ontario NUANS Report, the required legal designation should be included in the proposed corporate name on the report.
Assuming the legal ending is the distinctive term
For:
Qavellis Robotics Inc.
the likely distinctive term is:
Qavellis
not:
Inc.
Choosing an ending without checking the intended legal name
Your NUANS order should reflect the corporation name you genuinely intend to use.
Before submitting the order, read the complete proposed name from beginning to end.
Frequently Asked Questions
Should my Ontario NUANS Report include "Inc."?
Yes, if Inc. is the legal ending you intend to use.
Ontario requires the legal designation to be included on the NUANS Report.
Should I put "Inc." in the business name field?
If the order form has a separate Legal Ending field, normally enter the main business name without Inc. and select Inc. separately.
For example:
Business Name: Silverline Studios
Legal Ending: Inc.
My business name already ends in Inc. What should I do?
If the ordering form has a separate legal-ending selector, remove Inc. from the business-name field and select Inc. separately.
This prevents the ending from being entered twice.
Can I use Corp. instead of Inc.?
Yes, Corp. is an accepted legal element for an Ontario business corporation.
Choose the legal ending that matches the corporation name you intend to use.
Can I use Ltd. instead of Inc.?
Yes, Ltd. or Limited can be used as a legal element for an Ontario business corporation.
Make sure the NUANS Report reflects the legal name you intend to file.
Is "Corporation" the same as "Corp."?
Corp. is the abbreviated form of Corporation.
Both can serve as the legal element of an Ontario corporation name.
Is "Incorporated" the same as "Inc."?
Yes.
Inc. is the abbreviated form of Incorporated.
Does changing Inc. to Corp. make the corporation name different?
The legal element changes, even though the distinctive portion of the name may remain the same.
For NUANS and filing purposes, the safest approach is to make sure the proposed name on the report matches the legal name you actually intend to use.
Can I leave the legal ending blank on an Ontario NUANS Report?
For Ontario NUANS Reports, the legal designation is required on the report.
Choose the appropriate legal ending before submitting the order.
Is Inc. the distinctive term?

Northstar
Before You Submit Your Ontario NUANS Order
Take a few seconds to verify the complete proposed corporation name.
Check:
- Spelling
- Spaces
- Punctuation
- Distinctive term
- Legal ending
If the ordering form separates the Business Name and Legal Ending, enter each part only once.
For example:
Business Name: Qavellis Robotics
Legal Ending: Inc.
Result:
Qavellis Robotics Inc.
That is much safer than leaving the provider to interpret conflicting information.
