A guarantor is a person who promises to pay a debt if the primary borrower fails to pay. In Canada a guarantee is usually a secondary obligation, meaning the lender is expected to look to the borrower first, though the contract wording can change that.
A guarantor is someone who agrees to answer for another person's debt. The borrower remains primarily responsible, and the guarantor steps in if the borrower does not pay. That is the classic structure, and it is why guarantees are common in business lending, commercial leases, and some larger consumer loans. The Clicklaw Wikibooks guide from Courthouse Libraries BC explains the difference between guaranteeing and co-signing, and the FCAC joint-borrower page covers the shared responsibility that applies when a person is a joint borrower rather than a guarantor.
The word guarantor is often used loosely. Some people say guarantor when they mean co-signer, and some lenders use the terms in ways that do not match the classic legal distinction. Because the consequences differ, the only reliable approach is to read the actual contract and understand which role it creates.
How a guarantee works
A guarantee is a contract between the guarantor and the lender. The guarantor promises that if the borrower does not perform, the guarantor will. In its classic form, the guarantor's obligation is secondary: the lender must first look to the borrower, and only if the borrower defaults does the guarantor become liable. Many guarantees also require the lender to give notice of default before calling on the guarantee. Those protections depend entirely on the wording of the document and on the law of the province that governs it.
In practice, many modern guarantees are drafted to make the guarantor liable as a principal debtor and jointly and severally with the borrower. That language removes the secondary character of the obligation and lets the lender pursue the guarantor directly, much like a co-signer. If you are asked to guarantee a debt, read the clause that describes your liability and ask the lender to explain, in writing, when it can pursue you.
Guarantor versus co-signer
The table below summarises the main differences. The contract controls, so treat this as a guide to what to look for rather than a substitute for reading the document.
| Feature | Guarantor | Co-signer (joint debtor) |
|---|---|---|
| Nature of obligation | Usually secondary, triggered by default | Generally primary and immediate |
| Who the lender pursues first | Usually the borrower | Either party, at the lender's choice |
| Amount | Usually up to a guaranteed limit | Generally the full balance |
| Notice of default | Often required by the contract | Usually not required |
| Credit reporting | May or may not be reported | Often reported as a joint account |
| Common use | Business credit, leases, some loans | Consumer loans, auto, student credit |
Types of guarantee
Guarantees come in several forms, and the type matters as much as the label. A specific or limited guarantee covers a defined obligation, such as a single loan for a set amount. A continuing guarantee covers a course of dealing, such as a line of credit that may be drawn and repaid repeatedly, which means the guarantor's exposure can continue or grow. A joint and several guarantee makes the guarantor liable alongside the borrower without the lender having to pursue the borrower first. A guarantee may also be limited by amount, by time, or by the type of obligation covered. Before signing, identify which type you are being asked to give and whether the amount is capped.
When guarantees are used
Guarantees are common where the lender wants extra security but does not want to add another borrower to the account. Small business owners are often asked to give personal guarantees for company credit. Commercial landlords commonly require a personal guarantee from a business owner or a director. Lenders may also ask for a guarantee on a large consumer loan where the borrower's income is hard to verify. In each case, the lender gains a second source of repayment without making that person a co-owner of the debt.
Your obligations as a guarantor
If you give a guarantee, you may be required to pay the outstanding amount, plus interest and any costs the contract allows, if the borrower defaults. You may also have to deal with the lender directly if the borrower will not communicate. Your credit file may be affected, depending on how the lender reports the guarantee. And you may find it difficult to withdraw: many guarantees cannot be cancelled unilaterally while the underlying credit remains outstanding. If the guarantee is continuing, it may cover new borrowing you did not specifically approve.
Common mistakes
- Signing a guarantee without reading the liability and enforcement clauses.
- Assuming the lender must always pursue the borrower first.
- Giving a continuing guarantee without a cap on the amount.
- Believing a guarantee ends automatically when the original loan is repaid.
- Not asking how the guarantee will be reported on your credit file.
- Failing to get independent legal advice before signing a large guarantee.
If you are asked to guarantee a debt, get the document reviewed, ask for a cap if one is not offered, and confirm in writing when and how the lender can call on you. Those three steps turn a vague promise into a decision you actually understand.
How guarantees come to an end
A guarantee does not always end when the original loan is repaid. If the guarantee is continuing, it may cover future credit, so repaying one balance does not necessarily release you. A guarantee typically ends when the underlying credit facility is closed and all amounts are paid, when the lender agrees in writing to release you, or when the guarantee reaches its stated expiry or limit. In some cases a lender will release a guarantor when the borrower has built a strong enough file to stand alone, but that is a discretionary decision. If you give a guarantee, ask at the outset what events would end it and get the answer in writing.
Guarantees in business lending
Personal guarantees are routine in small business lending. A bank may lend to a corporation but require the owner or director to guarantee the debt personally. That means the business failure can become a personal financial problem. Commercial leases often work the same way, with the owner guaranteeing the rent for the term. If you are asked to guarantee business credit, find out whether the guarantee is limited to a specific facility or covers all obligations to the lender, whether it is capped, and whether it survives changes in the business structure. These questions are best answered by a lawyer or accountant before you sign, not after.
Checklist before you guarantee
- Confirm whether the guarantee is specific, continuing, or joint and several.
- Check whether the amount is capped and whether future advances are included.
- Ask when and how the lender can call on the guarantee.
- Ask how it will be reported to the credit bureaus.
- Ask what would release you, and get it in writing.
- Get independent legal advice for any large or continuing guarantee.
