  • A personal guarantee is a legal contract in which you agree to be personally responsible for your corporation's debt if the corporation fails to repay it.
  • Understanding the type you are being asked to sign matters.
  • Lenders present guarantee documents as standard, non-negotiable.

A corporation gives its owners limited liability — the debts of the company are not automatically your personal debts. That protection, however, largely disappears the moment you sign a personal guarantee on a business loan. Yet most small business owners in Ontario sign guarantees without fully understanding the commitment they are making.

A personal guarantee on a business loan is one of the most consequential documents a business owner can sign. This article explains what it means, the key terms to negotiate, and what options exist to protect yourself.

What Is a Personal Guarantee?

A personal guarantee is a legal contract in which you agree to be personally responsible for your corporation's debt if the corporation fails to repay it. You are essentially telling the lender: "If my company cannot pay, I will."

From the moment you sign, your personal assets — your home, savings, car, and other property — are potentially on the line for the corporation's debt.

Guarantees are almost universally required by:

The fact that guarantees are common does not mean they are not serious. Each one is a binding legal obligation.

Types of Guarantees

Not all guarantees are identical. Understanding the type you are being asked to sign matters.

Unlimited vs. limited guarantees

An unlimited guarantee makes you personally liable for the full amount of the loan, plus interest, fees, and enforcement costs — no cap. You are essentially a co-borrower.

A limited guarantee caps your exposure at a specific dollar amount. Even if the loan balance exceeds that amount, your maximum personal liability is fixed. Negotiating a cap is one of the most valuable things you can do before signing.

Continuing vs. specific guarantees

A continuing guarantee covers all present and future obligations of the corporation to the lender — not just the loan you are signing today, but any future credit the lender extends. This can expand your exposure significantly over time.

A specific guarantee covers only a identified debt or transaction.

Joint vs. joint and several guarantees

If multiple owners are guaranteeing a loan, the lender may require a joint and several guarantee. This means each guarantor is individually liable for 100% of the debt — the lender can pursue any one of you for the full amount, not just your proportionate share. The guarantor who pays can then seek contribution from the others, but that is a separate legal process.

What Lenders Want and What You Can Negotiate

Lenders present guarantee documents as standard, non-negotiable. That is often not entirely true. Points worth raising:

Dollar cap

If the lender will not drop the guarantee requirement, ask for a specific dollar limit. Caps are commonly negotiated on SBA-style facilities and commercial real estate loans in Canada.

Time limit

Some guarantees can be limited to a set period or expire when the loan balance drops below a threshold.

Release on equity milestones

You may be able to negotiate an automatic release of the guarantee if the company achieves certain performance targets or if you reduce your ownership stake.

Spousal consent

In Ontario, if your home is in both your name and your spouse's name, a lender may require your spouse to sign a separate consent or acknowledgment confirming they understand the guarantee may affect the family home. This is not a co-guarantee, but it puts your spouse on notice.

Independent legal advice

Some lenders require the guarantor to sign a certificate confirming they received independent legal advice before signing. Even when not required, obtaining ILA is prudent — it demonstrates you understood the document and makes it harder to later claim you did not.

What Happens When You Are Called on the Guarantee

If your corporation defaults on the loan, the lender can:

  1. Demand payment from you personally.
  2. Sue you and obtain a judgment against you personally.
  3. Enforce the judgment against your personal assets — including garnishing your wages, placing a lien on your home, or seizing non-exempt property.

The lender generally does not need to exhaust its remedies against the corporation before pursuing you. Unless the guarantee requires the lender to proceed against the corporation first (a "guarantee of collection" rather than a "guarantee of payment"), you can be pursued directly.

Reducing Personal Risk Before Signing

Before you sign a guarantee, consider:

Frequently asked questions

Can I get out of a personal guarantee after signing it?

Generally not unilaterally. The guarantee is a binding contract. Lenders may release you if the loan is fully repaid, if you negotiate a release as part of a loan refinancing, or in some cases if you sell your interest in the business. Retiring from a corporation does not automatically discharge a guarantee you already signed.

Does incorporating protect me from personal liability entirely?

Incorporation limits liability for business debts and torts — but personal guarantees are a voluntary waiver of that protection. Directors can also face personal liability for unpaid wages, HST remittances, and certain regulatory obligations under specific statutes. Limited liability has exceptions.

What if the lender sues me on the guarantee but the corporation is still operating?

The lender can sue you personally as a guarantor without necessarily first pursuing the corporation, unless the guarantee agreement specifies otherwise. A judgment against you personally is enforceable against your personal assets even while the corporation continues in business.

Are there any assets in Ontario that are protected from creditor enforcement?

Some assets are exempt from seizure under Ontario's Execution Act and related legislation — certain basic household goods and limited amounts of equity in specific tools. As of writing, the exemption amounts are modest — verify the current amounts with a lawyer. Ontario does not have the same robust homestead exemptions as some U.S. states.
