Asked to sign a guarantee for a loan, lease or business account? Tell Legal Route the parties’ names, your role, whether anything has been signed and any deadline. We will check conflicts and availability, explain consultation arrangements and any applicable fee, and confirm whether we can assist. An inquiry does not create a lawyer-client relationship or mean we have accepted a deadline.

A personal guarantee can make you personally responsible for specified business obligations even when the borrower or tenant is a corporation. The amount, duration and circumstances in which payment can be required depend on the guarantee, any indemnity, related documents and applicable law. The loan amount or a reassurance that signing is “just a formality” does not settle those questions.

This guide focuses on commercial guarantees connected with Ontario, including business loans, commercial leases and supplier credit. Governing-law provisions, the transaction and any special lending-program rules may affect the assessment.

Key takeaways

Company debt can become a personal commitment. Signing for the company and accepting an individual guarantee are different roles.
A stated limit needs context. Interest, costs, future debts and the wording of any cap can affect your exposure.
Leaving the business may not end the guarantee. A sale, resignation or closure requires a separate review of continuing obligations and any release.
Confirm who is advising you. The company’s lawyer does not automatically represent you personally as guarantor.

Why can I be personally liable if my business is incorporated?

Ontario corporate law generally limits a shareholder’s liability simply as a shareholder. A personal guarantee is a separate commitment given to a lender, landlord, supplier or another creditor. It can create liability beyond the money you invested in the company.

The proposed guarantor, borrower and creditor need to be identified accurately. Your ownership percentage or title does not, by itself, determine the obligations you accept. A spouse, family member or another person may also be asked to provide a guarantee without owning the business.

A guarantee may appear within a credit application, lease schedule, renewal or other agreement rather than in a document titled “Personal Guarantee.” The whole transaction matters.

Is a guarantee the same as an indemnity?

They can create different obligations. A guarantee generally supports another party’s obligation. An indemnity may create a separate primary obligation to cover specified losses. A document can contain both, including wording that treats the guarantor as a principal debtor in particular circumstances.

Those provisions can affect available arguments if the underlying debt changes or cannot be enforced against the business. The label on the document is not enough to determine the result.

What does a limited or continuing guarantee actually cover?

A useful review considers the complete wording rather than only the amount shown on the first page:

The obligations: one loan or lease, a particular account, or a wider group of present and future debts.
The limit: whether a stated cap includes interest, legal costs and other charges, or whether some amounts may be added.
The duration: whether the guarantee continues through renewals, further advances or replacement arrangements.
Changes and waivers: what the document says about amendments, extensions, security or notice to the guarantor.
The parties: whose debts are covered and whether the limit applies to each guarantor individually or to the group collectively.

“Continuing” and “unlimited” describe different questions. A guarantee can have a financial cap while continuing to support future obligations. Conversely, the amount originally borrowed does not necessarily describe the total liability under an uncapped document.

The same loan can involve different personal commitments

One proposed guarantee covers only a named loan and includes an overall liability limit. Another covers the borrower’s present and future obligations, with a principal cap but separate interest and enforcement-cost provisions. Even if the initial loans are the same size, the personal commitments may differ. The complete wording determines the comparison.

Must the creditor pursue the company before asking me to pay?

Not necessarily. Some guarantees permit recourse against a guarantor without first suing the business or exhausting its assets. The payment trigger, any demand requirement, related security and applicable law need review.

A creditor holding business collateral does not automatically mean the guarantor is responsible only for an eventual shortfall. That depends on the obligations actually agreed to. A lender’s description of its usual collection practice is not a substitute for the document.

How is liability shared between business partners or guarantors?

Equal ownership does not necessarily mean equal liability to the creditor. Joint and several wording may allow the creditor to seek the covered amount from one guarantor, subject to the agreement and applicable law.

A separate arrangement between owners about sharing a debt does not, by itself, change the creditor’s rights. Whether a cap is individual or collective, and what rights may exist between guarantors, requires separate attention.

Does a guarantee put my home or other assets at risk?

A personal guarantee creates a potential personal obligation; it is not necessarily a mortgage over your home or a security interest in a named asset. Separate security documents may form part of the transaction.

Even where no specific collateral is listed, personal liability can expose a guarantor to a claim and, if the creditor obtains an enforceable judgment, enforcement against assets permitted by law. Ownership, exemptions, existing security, priorities and enforcement rules affect which assets may be reached. Neither “no collateral” nor “personal guarantee” alone answers what could happen to a particular property.

What happens if I sell the business, resign or the company closes?

A sale of your shares, departure as a director or closure of operations should not be assumed to end a separate guarantee. The creditor’s agreement to a release, and the terms of any replacement arrangement, can be important.

A buyer’s promise to take responsibility for business debts may give you rights against the buyer without releasing you from the creditor’s claim. Similarly, the borrower’s insolvency does not automatically eliminate the guarantor’s obligations.

Renewals, amendments and changes to the underlying obligation can affect a guarantee, but not every change releases the guarantor. Consent, advance authorization, waivers and the circumstances all matter. An available right to end future coverage may also leave existing obligations in place.

Why might independent legal advice be requested?

The borrower, its owners, the lender and an individual guarantor can have different interests. A lawyer acting for the company does not automatically act for you personally. The client, role and any conflict need to be established before advice is provided.

Independent legal advice involves explaining the nature and consequences of the proposed commitment; it is more than witnessing a signature. A lender may request particular advice or documentation. There is no universal rule that the absence of an independent-advice certificate makes every Ontario guarantee unenforceable.

Legal advice also serves a different purpose from a financial assessment. Understanding the legal commitment does not establish that borrowing is affordable or that the business will succeed.

What to include in your first inquiry

Your name and role, and the names of the business, creditor and proposed guarantors.
Whether the request concerns a loan, lease, supplier account, renewal or business transaction.
Whether documents have already been signed, a demand received or another lawyer retained.
Any proposed signing, funding or response date, and whether independent legal advice has been requested.

You can contact us before assembling every document. Wait for secure intake instructions before sending financial statements, identification, confidential agreements or other sensitive records.

How can Legal Route help with a personal guarantee?

Legal Route provides business-law services through a lawyer licensed by the Law Society of Ontario. Subject to conflicts, availability and an agreed retainer, we can review the guarantee and connected documents, explain the proposed obligations, assess terms to discuss, and advise on amendments, releases or a resulting dispute.

A focused review of a proposed guarantee involves different work from negotiating financing, assessing an existing demand or advising on an owner’s exit. We confirm whom we represent, the proposed scope, fees, taxes and disbursements. If independent legal advice is requested, we first assess whether we can accept that role.

Frequently asked questions

Can I guarantee a business debt without owning shares?

Yes, a person may be asked to support another party’s obligations without being an owner. The absence of shares does not, by itself, remove a commitment you accept.

Does a cap mean I cannot owe anything above that figure?

Not necessarily. The document may treat interest, costs or other amounts separately. Whether the figure is an overall limit needs review.

Do I only owe half if my business partner also signs?

Not automatically. The guarantee may impose joint and several liability. Ownership proportions and arrangements between partners are separate questions.

Does obtaining independent legal advice remove the risk?

No. Advice helps you understand the commitment; it does not insure the debt, guarantee financing approval or release the obligation.

Can I arrange a review of just the guarantee?

A focused engagement may be possible, but the underlying loan, lease or credit documents may also be needed. We explain the materials, scope and fees before undertaking the work.

What if I have already signed or received a payment demand?

A review may still be useful. Tell us what was signed, what has happened and the relevant dates. The wording, surrounding circumstances and legal time limits require assessment; an inquiry does not suspend a deadline.
