What are business owners actually agreeing to when they sign a personal guarantee in Ontario? A personal guarantee is often treated as a formality, but it is not. It is a separate obligation that sits outside the company and attaches directly to the individual who signs it.
This guide explains how a guarantee is structured and why it operates independently from the main contract. It also covers how guarantees work on commercial loans, what you can negotiate before signing, and how to get released later.
Key Takeaways
- A personal guarantee is a separate obligation. It attaches directly to the individual, not just the company.
- If the company fails to meet its obligations, the guarantor becomes personally responsible.
- A guarantee typically operates independently from the main contract, even if the company disputes its own obligations.
- On commercial loans, guarantees often cover principal, interest, fees, enforcement costs, and future advances.
- Joint and several guarantees let a lender pursue any one guarantor for the full debt.
- Corporate security does not eliminate personal exposure. Both can be enforced.
- Scope, amount, and duration can sometimes be negotiated, but only before signing.
This guide draws on more than ten years of experience reviewing and negotiating personal guarantees for Ontario business owners.
Why Personal Guarantees in Ontario Are Not a Formality
Business owners are often told a personal guarantee is standard, routine, or just paperwork. That framing understates what is actually being signed.
A guarantee creates a real, enforceable obligation. It exists outside the company, which means the usual protection of limited liability does not apply to it.
Signing one means personally standing behind an obligation that would otherwise belong only to the company. This is worth pausing on before signing, not after a dispute has already started.
How a Personal Guarantee Is Structured
A guarantee creates direct liability for the person who signs it.
If the company fails to meet its obligations, the guarantor becomes responsible for them. This liability is not limited to specific assets, unless the guarantee is deliberately structured that way. Without that limitation, the obligation can reach the guarantor's personal assets broadly.
The obligation is personal. It does not depend on the guarantor being a shareholder, a director, or having any ongoing role in the company at all.
Why a Personal Guarantee Is Separate From the Main Contract
A guarantee is often signed alongside the main agreement, but it operates independently from it.
Even if the company disputes its obligations, the guarantor may still be required to perform under the guarantee. The guarantee generally does not rely on the same defences available to the company.
A dispute that slows down or blocks a claim against the company will not necessarily protect the guarantor. A claim can still be brought directly against them.
This independence often surprises business owners. Many assume their personal exposure automatically follows whatever happens to the company's own dispute.
Unlimited vs. Limited Personal Guarantees in Ontario
Guarantees are not all structured the same way. The difference matters enormously to how much risk a guarantor is actually taking on.
Unlimited Guarantees
An unlimited guarantee has no cap on the amount the guarantor could owe. It typically covers the full obligation under the agreement, whatever that turns out to be. This includes future increases in the amount owed.
This is the broadest, and riskiest, form of guarantee. Lenders and landlords often prefer it, since it leaves them with the strongest possible position if the company defaults.
Limited Guarantees
A limited guarantee caps the guarantor's exposure at a specific dollar amount, or ties it to a defined portion of the obligation.
This gives the guarantor a clear ceiling on their personal risk, even if the company's obligations later grow larger. Many guarantees default to unlimited unless a cap is specifically negotiated.
The Scope of Liability Under a Personal Guarantee
Many guarantees are broader than the person signing them expects.
A guarantee may cover all obligations under the agreement, not just the amount discussed at signing. This can include future amendments, extensions of the term, or additional amounts advanced later.
Without clear limits, this exposure can expand well beyond what the guarantor originally anticipated.
This is why reading the actual scope language matters more than relying on how the guarantee was described in conversation. The document itself, not the conversation around it, is what a court will look to if a dispute arises.
Personal Guarantees on Commercial Loans
Personal guarantees are most common in commercial lending. Banks and private lenders routinely require them from the owners of a borrowing company, usually alongside the commercial loan agreement and security documents.
What a Loan Guarantee Typically Covers
On a commercial loan, a guarantee is rarely limited to the principal. It often covers interest, fees, and the lender's enforcement costs as well.
Depending on how it is drafted, it may also extend to future advances or other obligations the company owes the same lender. The guarantor is backing the whole lending relationship, not a fixed amount.
Continuing Guarantees and Future Advances
Many loan guarantees are continuing in nature. They stay in effect until formally released, even as the underlying loan changes.
If the company refinances, increases the loan, or takes on related obligations with the lender, the guarantee may keep applying. This is often not obvious at the time of signing.
How a Guarantee Works Alongside PPSA Security
A guarantee is separate from the security a lender takes over the company's assets. That security is usually a general security agreement registered under Ontario's Personal Property Security Act. Our guide to PPSA security registration in Ontario explains what that registration covers.
Lenders will often enforce against the company's assets first. If a shortfall remains, they can pursue the guarantor directly. Corporate security does not eliminate personal exposure.
When Lenders Enforce a Guarantee
Enforcement usually follows a default by the borrower. If the business cannot repay the loan in full, the lender may seek recovery from the guarantor through legal proceedings, judgments, and enforcement against personal assets.
Unless the guarantee says otherwise, the lender does not need to exhaust its remedies against the company first. Guarantees from private lenders in Ontario are often broader and more aggressively enforced than bank guarantees.
How Personal Guarantees Interact With Limitation of Liability and Indemnity Clauses
Personal guarantees rarely appear alone. They typically sit alongside other provisions that shape how much risk an individual is actually carrying.
A guarantee's practical impact often depends on how it interacts with a limitation of liability clause elsewhere in the agreement. These provisions can cap some obligations while leaving the personal guarantee itself untouched.
Guarantees also frequently work alongside indemnity clauses. These address a related but separate question: how losses actually get compensated once liability is established.

Joint and Several Guarantees: When Multiple Owners Sign
Where a business has more than one owner, guarantees are often signed by multiple individuals at once. How that is structured changes what each person is actually exposed to.
A joint and several guarantee means each guarantor can be held responsible for the entire obligation, not just a share.
A lender can pursue whichever guarantor has the most available assets. That person is then left to seek contribution from the others afterward.
A guarantee structured on a several basis, by contrast, limits each guarantor to a defined portion of the total obligation. This is generally more favourable to the individuals signing. Lenders often resist it, since it weakens their overall position.
Business partners signing a guarantee together should understand which structure applies before signing. The difference can be significant if the company later runs into trouble.
What You Can Negotiate Before Signing
Guarantees are not identical across transactions. In some cases, scope can be limited by capping the total amount, restricting the guarantee to specific obligations, or limiting its duration.
Whether these changes are available depends on the lender or counterparty, the strength of the business, and the overall deal. Once the guarantee is signed, its terms define your exposure.
A few questions tend to reveal how much exposure a guarantee actually creates.
Does the Guarantee Cap the Total Amount?
Confirm whether liability is capped at a specific figure or extends to the full, uncapped amount owing.
Is the Guarantee Limited to This Agreement Alone?
Check whether it applies only to the current loan or contract, or extends automatically to future advances and other obligations.
Is Liability Joint and Several With Other Guarantors?
Understand whether you could be pursued individually for the entire debt, regardless of what others contributed.
Can the Guarantee Be Released or Limited in Duration?
Ask whether the guarantee can be discharged once specific conditions are met, rather than staying open-ended.
How to Get Released From a Personal Guarantee
A personal guarantee does not automatically end when a guarantor leaves the company or sells their shares.
The guarantee remains in force until the lender or counterparty formally releases the guarantor in writing. It also ends once the underlying obligation is fully repaid.
Departing shareholders and directors should confirm this release is actually documented. Exiting the company does not, by itself, end their personal exposure.
This is a common gap that surfaces later. A business owner may discover, years after leaving a company, that an old guarantee is still technically active.
The Bottom Line on Personal Guarantees in Ontario
A personal guarantee is not a supporting clause. It is a direct transfer of risk from the company to the individual who signs it.
Its impact depends on scope, not on how it is described. An unlimited, continuing guarantee with no defined end date can expose a guarantor to far more than expected, especially on a commercial loan.

Frequently Asked Questions
What is a personal guarantee in Ontario?
A personal guarantee is a separate legal obligation that makes an individual personally responsible if their company fails to pay or perform. It sits outside the corporation, so the usual protection of limited liability does not apply to it.
Guarantees are common in leases, supplier agreements, and especially commercial loan agreements. Because the obligation is personal, it can reach the guarantor's own assets, even if they later stop being a shareholder or director in the company.
What is the difference between an unlimited and a limited personal guarantee?
An unlimited guarantee has no cap. It covers the full obligation, including interest, fees, enforcement costs, and any future increases in the amount owed. A limited guarantee caps your exposure at a specific dollar amount or a defined portion of the debt.
Many guarantees default to unlimited unless a cap is negotiated before signing. A limitation of liability clause elsewhere in the agreement will not necessarily limit the guarantee, so ask for a separate cap.
Does a personal guarantee on a commercial loan cover more than the principal?
Usually, yes. Loan guarantees often cover interest, fees, and the lender's enforcement costs, not just the amount borrowed. Many are also continuing guarantees, meaning they can extend to refinancing, increased limits, and future advances unless specifically limited.
Lenders typically take PPSA security over the company's assets as well, registered under the Personal Property Security Act, but that corporate security does not reduce your personal exposure if the company's assets fall short. Read the scope clause before you sign.
What does joint and several liability mean for guarantors?
It means a lender can pursue any one guarantor for the entire debt, not just their share. If three owners sign a joint and several guarantee, the lender can choose whoever has the most accessible assets.
That person must then seek contribution from the others.
A several guarantee instead limits each person to a defined portion. This matters most when shareholder disputes or a partner's exit leave co-owners with different abilities to pay. Lenders often resist several structures.
Does a personal guarantee end when I leave the company?
No. Leaving the company, resigning as a director, or selling your shares does not end a personal guarantee. It stays in force until the lender or counterparty releases you in writing, or until the underlying obligation is fully repaid.
If you are exiting through a share sale, consider making the release a closing condition.
