If you registered a business name in Ontario — for a sole proprietorship, a partnership, or a corporation operating under a name other than its own legal name — that registration does not last forever. It runs on a five-year term, and renewing your business name registration before it expires is entirely your own responsibility. Ontario does not promise you a reminder.
Letting a registration lapse does not shut your business down, but it creates real problems, from banking and contract headaches to questions about whether you're properly entitled to operate under that name at all. Here is what the renewal actually involves and what to do if you've already missed it.
What a Business Name Registration Actually Covers
Under Ontario's Business Names Act, you must register any business name other than your own exact legal name (for an individual), your partnership's name, or a corporation's own legal corporate name. This applies whether you're a sole proprietor operating as "Jane Smith Consulting," a partnership, or a corporation doing business under a trade name different from the one on its articles.
Registration puts your business name on the public record, which is what lets banks, landlords, and customers confirm who is actually behind the name. It does not give you exclusive rights to the name, incorporate you, or create any personal-liability protection — it's simply a public disclosure requirement.
The Five-Year Renewal Window
An Ontario business name registration is valid for a five-year term from the date it's filed. As of mid-2026, the standard registration fee is $60, and renewal is generally available starting up to six months before your expiry date and for up to sixty days afterward. Figures and windows like these are set by government fee schedules that change from time to time, so confirm the current amount and dates before you rely on them.
You don't need to wait until the exact expiry date. Renewing early, well within that pre-expiry window, is the simplest way to avoid the lapse problem altogether.
What Happens If You Miss the Deadline
If the registration lapses and you don't renew within the post-expiry window, the registration is cancelled and you are, from a legal standpoint, operating under an unregistered name. That creates a few practical risks:
- You fall out of compliance with the Business Names Act's registration requirement, which can be treated as an offence if left uncorrected.
- Banks and lenders often require an active, current business name registration to open or maintain an account in that name.
- Contracts and invoices issued under a lapsed name can raise awkward questions in a dispute about who you actually are and whether you had authority to use the name.
- Someone else could register the same name in the meantime, since an expired registration no longer reserves it for you.
None of this means your underlying business or corporation stops existing — a sole proprietor is still the same person, and a corporation's legal existence doesn't depend on its trade name registration. But operating under a lapsed name is a compliance gap worth closing quickly.
How to Renew a Business Name Registration
- Check your expiry date through the Ontario Business Registry using your existing business identification number.
- File a renewal, rather than a brand-new registration, if you're still within the eligible window — this keeps continuity on the public record.
- Confirm the current fee posted on the Ontario Business Registry before you pay, since government fees are adjusted from time to time.
- If the window has closed, you'll typically need to file a fresh registration rather than a renewal — treat this as a new filing and expect to pay the applicable registration fee again.
- Set a reminder for the next five-year cycle so this doesn't happen again — a surprising number of small businesses lose track of this simply because it's such an infrequent filing.
Business Name Renewal vs. Other Ontario Filings You Might Confuse It With
| Filing | What it does | How often |
|---|---|---|
| Business name registration/renewal | Discloses who operates under a trade name | Every 5 years |
| Corporation's annual return (Corporations Information Act) | Confirms/updates director, officer, and address information | Annually |
| Extra-provincial registration | Registers an out-of-jurisdiction corporation to carry on business in Ontario | One-time, with ongoing filings |
These are separate obligations with separate deadlines. Renewing your business name does not satisfy your corporation's annual return requirement, and vice versa.
Frequently asked questions
Does renewing my business name registration also renew my corporation?
No. A corporation's legal existence and its trade name registration are entirely separate filings with separate rules. Renewing a business name has no effect on your corporation's own annual filing obligations.
Can I renew online, or do I need to file by mail?
Ontario's Business Registry generally supports online filing for straightforward renewals, though some situations still require paper filing. Confirm the available method for your specific registration before you start.
What if I've changed the nature of my business since I first registered?
A significant change — a new legal structure, a materially different name, or new owners — may mean you need a new registration rather than a simple renewal. When in doubt, have a lawyer confirm which applies.
Is there a penalty for renewing late?
We don't have a confirmed penalty figure to cite here, and the consequence can depend on how long the lapse has gone on. The more pressing risk in practice is the operational fallout described above — banking, contracts, and someone else registering your name — so treat a lapsed registration as urgent regardless of any formal penalty.
