Renew Ontario Business Registration: 2026 Guide to Costs, Deadlines & How to Renew
If you registered a sole proprietorship, partnership, or business name in Ontario, your registration does not last forever. In most cases, an Ontario Business Name Registration is valid for five years and must be renewed to keep the registration active.
If you're searching for how to renew Ontario business registration, this guide explains exactly when to renew, how much it costs, what happens if you miss the deadline, how to renew through the Ontario Business Registry (OBR), and what to do if your business information has changed.
We'll also explain the difference between renewing a business registration and renewing a business licence in Ontario—two things that are often confused.
What Is an Ontario Business Registration?
An Ontario Business Name Registration is the provincial registration used when certain businesses operate under a name other than the owner's legal name or when a business structure requires registration with Ontario.
The registration system is administered through the Ontario Business Registry (OBR).
The terminology has changed over time. Before the Ontario Business Registry launched, many people referred to the document as a Master Business Licence (MBL).
Today, Ontario generally refers to it as a Business Name Registration or other entity-specific registration document.
The Ontario Business Registry allows businesses to register, renew, amend and cancel registrations online.
Which businesses may need to renew?
Depending on the structure, this can include:
The exact filing depends on the type of entity.
Does an Ontario Business Registration Expire?
Yes. Most Ontario Business Name Registrations are valid for five years.
Ontario states that a Business Name Registration expires every five years. The renewal window opens six months before the expiry date and extends for up to 60 days after expiry.
Ontario business registration renewal timeline
Timing | What you can do |
More than 6 months before expiry | Wait until the renewal window opens |
6 months before expiry | Renewal becomes available |
Expiry date | Registration reaches its expiry date |
Up to 60 days after expiry | Late renewal may still be available |
More than 60 days after expiry | You will need to register the business name again |
The safest approach is to renew before the expiry date rather than relying on the 60-day grace period.
Ontario's Business Names Act provides for renewal before expiry and late renewal within 60 days after expiry.
When Can You Renew an Ontario Business Registration?
You can generally renew an Ontario Business Name Registration within six months before its expiry date.
For example, suppose your registration expires: October 15, 2026
Your renewal window would generally begin: April 15, 2026
You could then renew before October 15 without waiting until the last minute.
If you miss the expiry date, Ontario allows a 60-day late-renewal period for registrations under the Business Names Act.
Example
Imagine your registration expires on: September 30, 2026
You should ideally renew between: March 30, 2026 and September 30, 2026
If you miss the September 30 expiry, the 60-day post-expiry period provides an additional opportunity to renew.
But don't treat this as an extra two months of normal operating time. Renewing before expiry is the better strategy.
How to Renew Ontario Business Registration Online
For an eligible registration, the renewal process can be completed through the Ontario Business Registry.
Step 1: Find your expiry date
Look at your existing Business Name Registration document.
Find the registration or expiry information and determine when your five-year term ends.
If you aren't sure when your registration expires, you may need to locate your original registration documents or check your Ontario Business Registry profile.
Here's a sample of where you can find the expiry date on your documents.
Step 2: Access your Ontario Business Registry account
You'll generally need:
An Ontario.ca Login
Your company's company key
Your business linked to your account
Ontario explains that a company key is a unique nine-digit code used to link and manage a business in the OBR.
Need a hand with the process? Launch a Business can help. If you're not sure how to access your Ontario Business Registry profile, don't have your company key handy, or simply don't want to navigate the renewal process yourself, Launch a Business can assist with your Ontario business registration renewal and help make sure the filing is completed correctly.
You don't have to figure it all out on your own.
Step 3: Select your business
Once your business is linked to your Ontario Business Account, locate the business registration you want to manage.
Step 4: Select "Renew"
Ontario's current OBR instructions state that the renewal option appears when you're within the six-month renewal window.
From your business profile, select "renew" under "make changes."
Step 5: Review your information
Before submitting the renewal, make sure your information is still accurate.
Pay particular attention to:
Business address
Principal place of business
Business activity
Owner information
Partner information
Contact information
If something has changed, determine whether you need an amendment or another filing rather than simply renewing unchanged information.
Step 6: Pay the government fee
The government fee depends on the type of registration.
Step 7: Save your renewed registration
Once the transaction is completed, keep the updated registration document with your business records. Your renewal is good for another 5 years!
How Much Does It Cost to Renew a Business Registration in Ontario?
As of 2026, Ontario's published information lists the following renewal fees:
Business structure | Government renewal fee |
Sole Proprietorship | $60 |
General Partnership | $60 |
Ontario Limited Liability Partnership | $60 |
Extra-Provincial Limited Liability Partnership | $60 |
Ontario Limited Partnership | $210 |
Extra-Provincial Limited Partnership | $210 |
Ontario states that the renewal cost is the same as the applicable new-registration cost for these business types.
Is the Ontario government fee the only cost?
Not necessarily.
If you use a private registration service, that provider may charge a separate service or filing fee in addition to the government fee.
Therefore, when comparing prices, look at:
Government fee + service fee + applicable taxes
rather than assuming the entire amount is the government fee.
What Happens If You Don't Renew Your Ontario Business Registration?
This is one of the most important parts of the renewal process.
If your registration has expired for more than 60 days, Ontario states that you cannot simply renew the expired registration.
Instead, you will need to register the business name again.
A new registration can result in a:
New Business Identification Number (BIN)
New company key
New registration record
This is why missing the renewal deadline can create unnecessary administrative work.
What if I am only a few days late?
If your registration has been expired for less than 60 days, you may still be able to complete a renewal through the OBR.
However, don't assume that an expired registration is equivalent to an active registration during that period.
If your registration is approaching expiry, renewing before the expiry date is the simplest option.
What Happens If My Ontario Business Registration Has Been Expired for More Than 60 Days?
If the registration has been expired for more than 60 days, Ontario says you must complete a new business name registration rather than a renewal.
You may be able to register the same business name again, but it is treated as a new registration.
Ontario indicates that the new registration will receive a new BIN and new company key.
Important
A new registration is not necessarily identical to simply extending the old registration.
If continuity of your business records matters, don't wait until the 60-day period has passed.
Can I Renew My Business Registration Before It Expires?
Yes.
The Ontario Business Registry makes renewal available six months before the expiry date.
This is useful because you don't have to wait until the final weeks before your registration expires.
Our recommendation
If you're already inside the six-month renewal period:
Renew it early.
There is little benefit to waiting until the last possible day.
Do I Need to Renew a Partnership Registration in Ontario?
Yes, depending on the type of partnership and registration involved.
A general partnership registered in Ontario is subject to the five-year registration period and renewal requirements.
If you're searching for:
register partnership Ontario
register a partnership business in Ontario
renew partnership registration Ontario
Ontario partnership renewal
the important distinction is that registering a partnership and renewing an existing partnership are separate transactions.
The Ontario Business Registry lists registration services for general partnerships, limited liability partnerships and limited partnerships.
How to Renew a General Partnership in Ontario
For a general partnership, the basic process is:
Locate the existing registration.
Confirm the expiry date.
Access the Ontario Business Registry.
Link the business to your Ontario Business Account if necessary.
Review the partnership information.
Select the renewal option.
Pay the applicable fee.
Save the updated registration documents.
The current government fee for renewal of a general partnership is $60.
What if the partners have changed?
This is where you should stop and review the filing requirements before simply renewing.
A change involving partners may require an amendment or another filing.
If you're adding or removing partners, don't assume that a straightforward renewal will update the legal record correctly.
How to Register a Partnership Business in Ontario
If you're not renewing an existing partnership and are actually starting one, the process is different.
A general partnership generally involves two or more owners carrying on business together.
Ontario lists General Partnership registration as one of the business registration services available through the Ontario Business Registry.
Before registering a partnership, consider:
Partners
Business address
Principal place of business
Business activities
Partnership agreement
Tax responsibilities
Liability
A provincial business registration does not replace a partnership agreement.
A written partnership agreement can address matters such as:
Profit sharing
Responsibilities
Contributions
Decision-making
Dispute resolution
What happens if a partner leaves
For complicated partnership arrangements, professional legal or accounting advice may be appropriate.
Ontario Business Registration vs Business Licence: What's the Difference?
This is one of the biggest sources of confusion.
A business registration is not necessarily a business licence.
An Ontario Business Name Registration registers your business name or applicable business registration with the province.
A business licence generally refers to a licence or permit required to legally conduct a particular type of business.
Those requirements can come from:
Municipal governments
Provincial regulators
Federal regulators
Industry-specific authorities
For example, a business may have a valid Ontario Business Name Registration but still require a municipal licence or industry-specific permit.
Do I Need to Renew a Business Licence in Ontario?
Possibly.
Whether you need to renew a business licence in Ontario depends on what your business does and which government authority issued the licence.
There is no single universal "Ontario business licence" that every business must renew.
For example, a municipality may require a particular business licence, while another business may need a provincial or industry-specific licence.
How to renew an Ontario business licence
The process depends on the licence.
Generally:
Identify the authority that issued the licence.
Check the licence expiry date.
Review renewal requirements.
Pay the applicable renewal fee.
Save your renewed licence.
So if you search "how to renew Ontario business license," the first question should be:
Which licence?
Your Business Name Registration renewal is handled differently from municipal or industry-specific licensing.
Does Renewing My Business Registration Renew My Business Licence?
No.
Renewing your Ontario Business Name Registration does not automatically renew separate municipal, provincial or industry-specific licences.
You may need to maintain several separate registrations, accounts and licences.
For example:
Requirement | May need separate renewal? |
Yes | |
Municipal business licence | Possibly |
HST account | Generally not a five-year renewal |
Payroll account | Generally not a five-year renewal |
WSIB obligations | Separate requirements may apply |
Industry licence | Possibly |
Professional licence | Possibly |
The key lesson:
Don't treat your five-year business registration renewal as a complete business compliance renewal.
Do Corporations Have to Renew Their Ontario Business Registration?
This is another major misconception.
An Ontario corporation generally does not renew every five years in the same way a sole proprietorship or business-name registration does.
Instead, corporations have ongoing filing obligations, including annual returns.
Ontario states that corporations must file an annual return through the OBR within six months of their fiscal year-end.
Sole proprietorship / partnership registration | Corporation |
Generally five-year registration | Ongoing corporate existence |
Renewal required | Annual return required |
Business Name Registration | Corporate record |
BIN associated with registration | Ontario Corporation Number |
Business name registration can expire | Corporation compliance requirements |
If you're operating through an Ontario corporation, don't use the five-year business-name renewal rules as a substitute for your corporation's annual compliance requirements.
Does Renewing My Business Registration Renew My CRA Business Number?
No.
An Ontario Business Identification Number (BIN) and a CRA Business Number (BN) are different identifiers.
Ontario itself distinguishes the provincial BIN from the CRA BN.
Your Ontario registration may involve:
Ontario: Business Identification Number (BIN)
CRA: Business Number (BN)
The CRA BN is associated with federal tax programs such as:
GST/HST
Payroll
Corporate income tax
Import/export
Renewing your provincial business registration does not mean you're registering for a new CRA tax account.
Likewise, renewing a business registration does not automatically register you for HST or payroll.
What Should I Check Before Renewing?
Don't automatically click "renew" without reviewing your information.
Use this checklist first.

What If My Address Has Changed?
If your business address has changed, don't simply assume that renewal will update everything automatically.
Ontario requires businesses and other entities to keep their registry information accurate and states that changes to applicable information must be reported within 15 days.
Depending on your business structure and the change involved, you may need to file an amendment or other change transaction.
Before renewing, ask:
Has anything changed since I originally registered?
If the answer is yes, identify the correct filing before completing the renewal.
What If My Business Name Has Changed?
A renewal is generally intended to continue the existing registration.
If you want to operate under a different business name, you should not assume that you can simply edit the name during renewal.
A different business name requires a new registration or another appropriate filing.
If you're considering changing your business name, review the Ontario requirements before submitting the renewal.
Do I Need a NUANS Report to Renew My Ontario Business Registration?
A NUANS report is not the same thing as a five-year business registration renewal requirement.
This is another area where business owners can encounter confusing information online.
NUANS searches are primarily associated with certain corporate name searches and registrations. To register or renew an Ontario Business Registration, you do not require a NUANS report.
But, sometimes it's a good idea to search your business name, just to make sure it's not being used by another business or corporation.
The Ontario government specifically notes that an Ontario-biased or weighted NUANS report is required for certain Ontario corporate registrations when using a non-numbered corporate name.
A standard renewal of an existing business-name registration is a different transaction.
Can I Renew My Ontario Business Registration Myself?
Yes.
Ontario provides online tools for business owners to manage eligible registrations through the Ontario Business Registry.
You will generally need an Ontario.ca Login, Ontario Business Account and company key to access and manage an existing business profile.
When might you want professional assistance?
A filing service can be useful if:
You cannot access your OBR account
You don't have your company key
Your registration has expired
Your business information has changed
You need to add or remove a partner
You're unsure whether you need an amendment
You want someone to handle the filing for you
You need several business registrations or changes completed together
The key is to understand exactly what transaction you need before paying a third party.
How Launch a Business Can Help With an Ontario Business Registration Renewal
If you don't want to navigate the Ontario Business Registry yourself, Launch a Business can assist with the filing process.
We can help with services such as:
HST registration
Payroll registration
Other business filings
The goal is simple: you provide the information, and we help take care of the filing process.
For businesses that have changed ownership, addresses, activities or structure, we can also help determine which type of filing is appropriate before proceeding.
Ontario Business Registration Renewal Example
Let's say Sarah registered: Sarah's Creative Studio
Her Business Name Registration was issued on: June 15, 2021
Her five-year registration period ends in: June 15, 2026
Sarah should have been able to access the renewal option beginning approximately: December 15, 2025
If she renewed before June 15, 2026, the renewal process would be straightforward.
If she waited until July 2026, she could still potentially be within the 60-day late-renewal period.
If she waited beyond the 60-day period, Ontario says she would need to register the business name again rather than simply renewing the expired registration.
The lesson
Don't wait until the registration expires.
Set a reminder for six months before expiry.
A Better Way to Manage Your Five-Year Renewal
Five years is a long time.
It's easy to forget when your registration expires.
A simple business compliance calendar can prevent this.
Recommended schedule
6 months before expiry
Check the registration and begin renewal.
3 months before expiry
Confirm business information and licences.
30 days before expiry
Make sure the renewal has been completed.
After renewal
Save the new registration and record the next expiry date.
This creates a simple recurring compliance system instead of relying on memory.
Common Ontario Business Registration Renewal Mistakes
1. Waiting until the last day
The biggest mistake is treating the expiry date as the day to start the process.
Better: Renew as soon as your six-month renewal window opens.
2. Confusing the BIN with the CRA BN
These are different identifiers.
3. Assuming renewal updates everything
A five-year registration renewal doesn't automatically update every government account or business licence.
4. Ignoring changes
If your address, business activity or ownership has changed, investigate the appropriate amendment or filing.
5. Assuming corporations renew every five years
Corporations have different compliance requirements, including annual returns.
6. Confusing a business registration with a licence
A Business Name Registration does not automatically satisfy municipal or industry licensing requirements.
7. Letting the registration expire for more than 60 days
Once the registration is more than 60 days past expiry, Ontario says a new registration is required rather than a renewal.

How do I register a partnership business in Ontario?

Do I need to renew my Master Business Licence?
If by "Master Business Licence" you mean an Ontario Business Name Registration, the registration generally expires after five years and needs to be renewed. Ontario now uses Business Name Registration terminology rather than the former MBL terminology.
Is a Business Name Registration the same as a business licence?
No. A Business Name Registration is a provincial business registration. A business licence may be required separately by a municipality, province or industry regulator.
How do I renew an Ontario business licence?
There is no single renewal process for every Ontario business licence. You must identify the authority that issued your licence and follow its renewal requirements.
Do corporations need to renew every five years?
No, not unless you're renewing a Tradename under that corporation. Ontario corporations themselves have different ongoing compliance requirements, including annual returns.
Does renewing my business registration renew my HST account?
No. An Ontario business registration renewal and a CRA GST/HST account are separate matters. An HST account does not need to be renewed.
Do I need a new Business Number when I renew?
Generally, a normal renewal does not mean you are creating a new CRA Business Number. The Ontario BIN and CRA BN are different identifiers.
Can I renew after my business registration expires?
Yes, if you are within the applicable 60-day late-renewal period. After more than 60 days, Ontario says you need to complete a new registration.
What if I lost my company key?
You can request a company key from the Ontario government. Ontario explains that the company key is a nine-digit code used to access and manage your business profile.
Should I renew my business registration if I am planning to incorporate?
It depends on your timing and circumstances. Incorporation creates a different legal structure, so don't assume that renewing a sole proprietorship is automatically necessary if you're immediately transitioning to a corporation. Consider the timing of the transition and whether you need the existing registration to remain active.
Final Ontario Business Registration Renewal Checklist
Before you finish, remember:
✓ Check your expiry date
✓ Renew within the six-month renewal window
✓ Don't rely on the 60-day grace period
✓ Confirm your business information
✓ Check whether your ownership has changed
✓ Check your municipal and industry licences
✓ Keep your Ontario BIN separate from your CRA BN
✓ Save your renewed registration
✓ Record your next renewal date
And if your registration has already been expired for more than 60 days, don't assume you can simply click "renew." Ontario's current guidance says you'll generally need to complete a new business-name registration.
