How to Renew a Business License in Ontario
If you're searching for how to renew a business license in Ontario, the first thing to know is that the term “business license” can mean different things.
For many Ontario small-business owners, the renewal they need is actually a Business Name Registration, commonly known as a Master Business Licence (MBL). A Business Name Registration is generally valid for five years and can be renewed online through the Ontario Business Registry (OBR) beginning six months before its expiry date and up to 60 days after expiry.
This guide explains exactly how the renewal works, how much it costs, what happens if your registration has expired, and how to determine whether you need a business-name renewal at all.
What Does “Renew a Business License” Mean in Ontario?
Ontario does not have one universal business licence that every business renews.
When people search for “renew business license Ontario,” they are often referring to renewing a registered business name.
The official Ontario terminology is now Business Name Registration. The term Master Business Licence (MBL) is still widely used by business owners and service providers to describe the document associated with a registered business name.
A Business Name Registration may apply to:
Sole proprietorships operating under a business name
General partnerships operating under a registered name
Certain partnership structures
Corporations operating under a registered trade name
Other business-name registrations covered by Ontario's Business Names Act
Ontario states that a business-name registration is effective for five years from the date it is accepted by the Registrar.
Business Name Registration vs. other licences
It is important not to confuse a Business Name Registration with a municipal or industry-specific licence.
Registration or licence | What it does | Renewal |
Business Name Registration / formerly Master Business Licence or MBL | Registers your operating/ business name with Ontario | Every 5 years |
Municipal business licence | Authorizes certain activities within a municipality | Depends on municipality |
Industry-specific licence | Regulates certain professions or activities | Depends on regulator |
CRA HST account | Tax account | Does not need renewing |
CRA payroll account | Payroll program account | Does not need renewing |
Creates a separate legal entity | Does not need renewing |
Bottom line: Renewing your Ontario Business Name Registration does not automatically renew every licence, permit or account your business may have.
When Do You Need to Renew Your Ontario Business Name Registration?
A Business Name Registration is valid for five years.
For example:
Original registration date: September 15, 2021
Expiry date: September 15, 2026
Ontario allows a renewal to be filed up to six months before expiry. The government also allows renewal for up to 60 days after expiry.
Your renewal window
Timing | What you can do |
More than 6 months before expiry | Wait until the renewal window opens |
Within 6 months before expiry | Renewal can be filed |
Expiry date | Registration expires unless renewed |
1–60 days after expiry | Grace period; Renewal is still available |
More than 60 days after expiry | Cannot be renewed; you need a new registration |
The Ontario government specifically states that the renewal option appears in the OBR account six months before the expiry date.
Do not wait until the last day
Although Ontario provides a post-expiry period, the safest approach is to renew before the registration expires.
Renewing early gives you time to deal with:
Incorrect business information
Missing OBR access
Company Key issues
Address changes
Ownership changes
Filing problems
Questions about whether you need a renewal or another type of filing
How to Renew a Business License in Ontario Online
If by “business licence” you mean your Ontario Business Name Registration, you can renew it online through the Ontario Business Registry (OBR).
Step 1: Confirm your expiry date
Before starting, locate your existing Business Name Registration and check the expiry date.
Your renewal window opens six months before that date.
If you're unsure when your registration expires, check your business records or access your business information through the Ontario Business Registry.
Step 2: Make sure you can access the Ontario Business Registry
To manage your business online through the OBR, Ontario says you need:
A company key
An Ontario.ca Login
An Ontario Business Account
These are used to establish access to your business profile.
What is a Company Key?
A Company Key is an authorization code associated with your business or corporation that helps you access and manage information in the Ontario Business Registry.
If you do not have the necessary access information, you may need to recover or request the appropriate credentials before completing the renewal.
Step 3: Sign into the Ontario Business Registry
Access the Ontario Business Registry through Ontario's online business services.
Once logged in, select your business from your profile.
Ontario confirms that business owners can use the OBR to renew their business-name registration and manage other business transactions.
Step 4: Select the renewal option
Once your business is selected, look for the renewal option under the available business transactions.
Ontario's current instructions indicate that the renewal option becomes available six months before expiry.
You can then begin the renewal filing.
Step 5: Review your business information
Before submitting, carefully check the information associated with your registration.
Look for:
Business name
Business Identification Number (BIN)
Owner information
Business address
Mailing information
Business activity
Partnership information, where applicable
What if my information has changed?
This is where you should stop and determine whether you need a renewal, amendment or another filing.
A renewal is not necessarily the same thing as updating your business information.
For example, if you moved and your registered business information needs to be changed, you may need to complete the appropriate amendment rather than simply treating the renewal as an opportunity to change everything.
Step 6: Pay the government renewal fee
Ontario's current government fee for many Business Names Act registrations is $60 when filed online.
The Ontario fee schedule lists:
Sole proprietorship renewal: $60
General partnership renewal: $60
Ontario LLP renewal: $60
Extra-provincial LLP renewal: $60
Ontario limited partnership renewal: $210
Extra-provincial limited partnership renewal: $210
The government confirms that online renewal service for standard Business Names Act registrations is processed immediately in its published fee schedule.
Always verify the current government fee before filing because government fees and service standards can change.
Step 7: Submit the renewal
Review your information carefully and submit the filing.
Keep your confirmation and renewal documentation for your business records.
The Ontario government says online business-name filings can provide immediate confirmation of the transaction, depending on the filing.
Step 8: Save your renewed Business Name Registration
After completing the renewal, save the updated documentation.
We recommend keeping:
A PDF copy
The confirmation email
Your BIN
The next expiry date
Your OBR access information in a secure location
This can make your next renewal much easier.
Can You Renew a Master Business License Online in Ontario?
Yes. What many people call a Master Business Licence can generally be renewed online as a Business Name Registration through the Ontario Business Registry.
The Ontario government currently describes the process as renewing your business name registration rather than renewing a separate “Master Business Licence.”
So searches such as:
“renew Master Business Licence Ontario”
“renew Master Business Licence Ontario online”
“renew business name registration Ontario”
“renew business license Ontario”
may all be referring to the same basic provincial business-name renewal process.
How to Renew My Business License in Ontario If It Has Already Expired
This is one of the most important parts of the renewal process.
If your Business Name Registration has expired, you may still be able to renew it—but only within the permitted post-expiry period.
If it expired less than 60 days ago
Ontario allows you to renew a Business Name Registration that has been expired for less than 60 days.
If it expired more than 60 days ago
You cannot simply renew the old registration.
Instead, Ontario requires you to submit a new business-name registration.
This means you will receive:
A new registration
A new Business Identification Number (BIN)
A new Company Key
Ontario explicitly states that registrations expired for more than 60 days cannot be renewed and must instead be registered again.
Example
Imagine your registration expired on July 1.
July 1: Registration expires
July 15: You can still renew
August 20: You can still renew
August 30: You may still be within the 60-day window, depending on the exact expiry date
After the 60-day period: A new registration is required
The important point is that the 60-day period is based on the actual expiry date—not a general “two-month” rule.
What Happens If You Don't Renew Your Ontario Business Registration?
If your registration expires and you do not renew it within the allowed period, you may have to register the business name again.
That can create unnecessary administrative work.
Potential consequences can include:
Losing the active registration for the name
Receiving a new BIN after re-registration
Having to provide registration information again
Updating organizations that rely on your business documentation
Potential confusion with banks, vendors or customers
Additional administrative work if the business name needs to be re-established
Important distinction
Do not assume that your CRA accounts automatically change because your provincial business-name registration expires.
The provincial registration and CRA program accounts are separate matters.
If your business has HST, payroll or other CRA accounts, make sure you understand your separate tax obligations.
How Much Does It Cost to Renew a Business License in Ontario?
For Business Name Act registrations, Ontario's current online government fee is $60.
Business type | Ontario government renewal fee |
Sole proprietorship | $60 |
General partnership | $60 |
Ontario LLP | $60 |
Extra-provincial LLP | $60 |
Ontario limited partnership | $210 |
Extra-provincial limited partnership | $210 |
These are government filing fees, not necessarily the total amount you may pay if you use a private service provider.
Ontario's published fee schedule should be treated as the authoritative source for government fees.
Government Renewal vs. Using a Business Renewal Service
You have two basic options.
Option 1: Renew it yourself
You can use the Ontario Business Registry directly.
Advantages
| Disadvantages
|
Option 2: Use a renewal service
A renew Master Business License service in Ontario can handle the filing for you.
This may make sense if:
You don't want to navigate the OBR
You're unsure whether your registration is still active
Your business information has changed
You need help understanding the filing
You want someone to handle the administrative work
What a service provider should tell you
Before paying for a renewal service, make sure you understand:
Government fee
Service fee
Total price
Processing timeline
What documents you'll receive
Whether amendments are included
Whether they will contact you if there is a filing problem
A reputable provider should clearly distinguish its own service fee from the Ontario government filing fee.
Renew Master Business License Ontario: Common Mistakes to Avoid
A renewal is straightforward, but several mistakes can cause problems.
Mistake 1: Calling every licence a “Master Business Licence”
A Master Business Licence/Business Name Registration is not the same thing as a municipal business licence or industry-specific licence.
Always identify what registration or licence you actually need to renew.
Mistake 2: Waiting until after expiry
You may have a 60-day post-expiry period, but that does not mean you should rely on it.
Renew before the expiry date whenever possible.
Mistake 3: Assuming a corporation needs a five-year MBL renewal
A corporation does not renew its existence every five years like a sole proprietorship's business-name registration. However, a corporation may have a registered trade name/business name that needs to be renewed.
If you're incorporated and unsure what exactly is expiring, check your corporate and business-name records separately.
Mistake 4: Confusing a BIN with a CRA Business Number
These numbers are different.
A Business Identification Number (BIN) is associated with Ontario business-name registration.
A Business Number (BN) is issued by the Canada Revenue Agency for federal tax programs.
Do not assume that your Ontario BIN and CRA BN are interchangeable.
Mistake 5: Assuming renewal updates your business information
Renewal and amendment are different transactions.
If your address, ownership structure, business activity or other information has changed, determine whether a separate filing is required.
Mistake 6: Assuming renewal handles municipal licences
It does not.
If your municipality requires a business licence, that licence has its own rules, renewal date and fee.
Renewing a Business Name vs. Amending a Business
Here's a simple way to decide what you need.
Situation | Likely action |
Registration is approaching expiry | Renew |
Registration expired less than 60 days ago | Renew |
Registration expired more than 60 days ago | New registration |
Business information changed | Amendment/change may be required |
You want to change the registered business name | Different filing/new registration may be required |
You are closing the business | Cancellation may be appropriate |
You are incorporating | Incorporation is a separate process |
If you're not sure which filing applies, don't automatically submit a renewal just because the document is expiring.
Do Corporations Need to Renew a Master Business Licence?
Not necessarily.
An Ontario corporation itself does not need to be “renewed” every five years.
However, if the corporation operates under a registered business name or tradename that is separate from its corporate legal name, that business-name registration may have a five-year renewal period.
Example
Legal corporate name: 1234567 Ontario Inc.
Operating name: Ottawa Home Renovations
The corporation is one legal entity.
The registered operating name is a separate business-name registration.
That operating-name registration may need to be renewed even though the corporation itself does not have a five-year renewal.
This distinction is particularly important for corporations that have been operating for several years.
What If My Business Information Changed Since I Last Registered?
Don't simply ignore the changes. Before submitting your renewal, compare the information on your existing registration with your current business information.
Common changes include:
Address
Business activity
Owner information
Partner information
Contact information
Depending on the change, you may need an amendment or another filing.
Does Renewing My Business Registration Renew My HST Account?
No.
Your Ontario Business Name Registration and CRA tax accounts are separate.
For example, a business might have:
Ontario Business Name Registration
CRA Business Number
GST/HST account
Payroll account
WSIB account
Municipal licence
Industry-specific licence
Renewing one does not automatically renew or update all the others.
The CRA's Ontario business guidance directs businesses to Ontario's Business Registry for provincial registration changes while maintaining separate processes for CRA program accounts.
Ontario Business Renewal Checklist
Use this checklist before submitting your renewal.
Before renewing
Confirm your business name
Find your BIN
Confirm your expiry date
Check whether you're within the six-month renewal window
Confirm your business information is accurate
Check whether your address has changed
Check whether ownership information has changed
Determine whether you need an amendment
Confirm you have OBR access or use a business renewal service
After renewing
Save your confirmation
Save your updated Business Name Registration
Record the new expiry date
Update your internal business records
Provide updated documentation to organizations that require it
Add a reminder for the next renewal
A Better Way to Manage Your Five-Year Renewal
Don't wait for an email reminder.
Create your own internal compliance calendar.
For example:
Renewal date: September 15, 2031
Set reminders for:
March 15, 2031 — Renewal window opens
July 15, 2031 — Internal renewal reminder
August 15, 2031 — Final preparation reminder
September 1, 2031 — Renew if not already completed
This gives you plenty of time to resolve unexpected issues.
What Documents Should You Keep?
Your business records should include the latest version of your registration.
Keep:
Current Business Name Registration
Previous registration, if useful for historical records
Filing confirmation
BIN
Business name information
Renewal/expiry date
Relevant amendments
Partnership documentation, if applicable
Digital records are usually the easiest to organize.
A simple folder could be:
Business Records → Ontario Registration → Business Name Registration
Then save the current document with the date.
When Should You Use a Professional Renewal Service?
DIY renewal is perfectly reasonable for a straightforward filing.
A service provider may be useful when you want someone else to handle the administrative process.
Consider using a service if:
You cannot access your OBR profile
You lost your Company Key
Your registration is close to expiry
Your registration has already expired
Your business information has changed
You're not sure whether you need a renewal or amendment
You're operating through a corporation and have a tradename
You simply don't want to deal with the government portal

For most people searching for “renew Master Business Licence Ontario,” the answer is a Business Name Registration renewal through the Ontario Business Registry.
Remember these four key points:
Business Name Registrations are generally valid for five years.
You can renew up to six months before expiry.
You generally have 60 days after expiry to renew.
After 60 days, a new registration is required instead of a renewal.
