Sign a personal guarantee on a $150,000 business loan and your corporation stops being a shield for that particular debt. Most Canadian owners find this out late, usually the day a demand letter arrives at their house instead of the shop.
A personal guarantee is a separate contract in which you promise to repay your company's debt out of your own money if the company cannot. It sits beside the loan agreement, it outlives the corporation, and across Canadian business lending it is rarely optional. What you can change is its shape: how much it covers, who else is on the hook beside you, and what has to happen before a lender can reach you.
One more thing before we get into it. Most of the advice online still repeats a rule that expired in 2014. Under the federal small business loan program, guarantees used to be capped at a quarter of the borrowing. They are not anymore, and that single change matters more than anything else on this page.
What a personal guarantee actually reaches
Incorporating separates you from creditors whose only claim is against the company. A guarantee builds a second road straight back to you. Both claims can be enforced at the same time, and corporate bankruptcy retires the company's obligation while leaving yours completely intact.
In practice, a lender who cannot collect from the business can sue you personally, register a judgment, garnish wages, and move against personal property. In most provinces a judgment creditor can register that judgment against real estate you own. Your home is not automatically safe simply because you never pledged it as security.
None of that means a guarantee is unreasonable. Lenders ask for one because a small company can be wound up in an afternoon, and because an owner with skin in the game behaves differently in a bad quarter. The Business Development Bank of Canada and every chartered bank in the country take them as standard practice. The problem is not that guarantees exist. It is that owners sign them without reading the four lines that decide how far they reach.
What a guarantee does not do on day one
Signing does not put a mark on your consumer credit file. A guarantee is a contingent promise rather than a credit account in your name, so nothing flows to Equifax Canada or TransUnion Canada at closing. Reporting begins only if the business defaults and the lender enforces. Then collections activity, a court judgment, or a settled balance lands on your personal file and sits there for years.
That gives you a clean way to think about the risk. A guarantee you never have to honour costs nothing on paper. A guarantee that gets called can follow you for six years or longer, and it will show up on every mortgage application you make in that window.
Which is why the underwriting conversation matters as much as the guarantee conversation. What a lender reads in your business bank statements shapes how much security they feel they need from you personally.
The four guarantee structures, and which one you are signing
Lenders do not use one document. Four structures show up repeatedly in Canadian business lending, and the gap between the best and worst of them is measured in houses.
| Structure | What you are liable for | When lenders use it | What to ask for instead |
|---|---|---|---|
| Unlimited guarantee | The full outstanding balance plus interest, enforcement costs and legal fees, with no ceiling | The default on most bank and alternative lending files | A stated dollar ceiling tied to the original principal |
| Limited guarantee | A named dollar amount or a fixed percentage of the original loan | Files with several shareholders, or borrowers with strong financials | Written confirmation that costs and interest sit inside the cap |
| Joint and several | The entire debt, collectible from whichever guarantor the lender picks | Two or more owners signing on the same file | Several liability split by shareholding |
| Several liability | Only your stated share of the debt | Uncommon, and almost always the result of negotiation | Confirmation your share cannot expand if a partner defaults |
Joint and several is the structure that ends partnerships. Own 30% of a company with two other shareholders and sign a joint and several guarantee alongside them. The lender can then collect the whole balance from whichever of the three of you has the most equity in their home. You would be left chasing your partners for their portion in a separate action, on your own dime, while the lender walks away paid.
The wording that quietly costs money
Ask for the cap in dollars. Phrases like "limited to your proportionate interest" read as protection and function as nothing of the sort. What decides the outcome is whether the document names a figure, and whether interest, enforcement costs and legal fees fall inside that figure or on top of it. In most agreements they land on top. On a defaulted six-figure facility, that difference alone can run into tens of thousands.
The same logic applies further down the risk ladder. Owners working through a bad credit business loan are usually the least able to negotiate structure and the most exposed when it goes wrong. Read harder, not faster.
What the CSBFP rules really say about guarantee limits in 2026
Search for guarantee limits in Canada and you will find the same claim on a dozen sites. Under the Canada Small Business Financing Program, a lender can only take a personal guarantee worth 25% of the loan. That was accurate once. It stopped being accurate on April 1, 2014.
Section 19 of the Canada Small Business Financing Regulations sets the ceiling in two parts. For a loan made before April 1, 2014, an unsecured personal guarantee is capped at 25% of the original loan amount. For a loan made after March 31, 2014, the ceiling is the original amount of the loan. On top of that number the lender may also add interest on any judgment, taxed court costs, and legal fees.
Read that twice if you carry a program loan on your books. On a $500,000 term loan registered in 2019, the guarantee ceiling is $500,000 plus costs, not $125,000. The program that accountants across the country still describe as the cautious option now carries the same personal exposure as a conventional bank facility. Honestly, if anyone tells you otherwise, ask them for the section number. There is not one.
Release only works while you are current
Section 21 of the same regulations says a lender may release a guarantor only if the loan is in good standing. That sentence closes the exit exactly when owners start looking for it. People ask about coming off a guarantee when the business is wobbling, which is the precise moment the rule stops permitting it. If you want out, you raise it during a quiet quarter, when the payments are boring and the lender has no reason to say no.
Substitution is the route that actually works
Section 22 allows a borrower to replace a guarantee, with the lender's consent, using security in the company's own assets or another guarantee of equal or greater value. That swap is behind most successful releases in the real world. A departing shareholder hands the guarantee to the incoming one. A company pledges equipment or receivables in place of an owner's signature. Nobody removes the security. They exchange it.
One more detail sits in section 19 and rarely gets mentioned: under this program the personal guarantee must be unsecured. A lender cannot register a charge against your house to back it. Conventional lenders, private lenders and most alternative lenders work under no such restriction, so the same signature carries a different weight depending on which product you are signing for. It is worth checking whether a business line of credit or a term facility gives you the better structure before you commit.
Five things to settle before you sign
Call this the five point guarantee review. Work through it with the lender while the deal is still being shaped, not after the documents come back from their lawyer.
- The number. Ask for a stated dollar ceiling, and ask in writing whether interest, enforcement costs and legal fees sit inside it or on top of it.
- The structure. Where there is more than one shareholder, push for several liability split by shareholding rather than joint and several. Expect resistance. Ask anyway.
- The release trigger. Ask for a written condition tied to something measurable, such as a debt service ratio held across four consecutive quarters or the balance falling under a set figure. A guarantee with no exit clause is a guarantee for life.
- The spouse. If a lender asks a non-owner spouse to sign, treat that as a separate decision with separate consequences. Both of you should take independent legal advice, from different lawyers, before either signature goes down.
- The sale. Ask what happens to your guarantee if you sell your shares or leave the partnership. Silence in the document means it follows you out the door.
You will not win all five. Two or three is a normal result on a file with decent numbers, and that is often the difference between a rough year and a lost house.
Solid Capital is a Canadian alternative lender built for business owners and homeowners the big banks decline or under-serve. The difference sits in the underwriting: we read the whole file, the bank statements, the revenue history, the context behind a soft quarter, instead of stopping at a credit score. That usually means the conversation about security starts from what the business can genuinely support rather than from a form. If that sounds like your situation, look at your business financing options or start an application. It takes about five minutes, there is no impact to your credit to apply, and a Canadian advisor reviews every file personally.
A guarantee is not paperwork. It is the second contract, the one that reaches past your corporation and into your savings account. Read it before closing day, not on it. Ask for the number. Then decide.
Frequently Asked Questions
Do you have to sign a personal guarantee for a business loan in Canada?
In most cases, yes. Canadian banks, alternative lenders and government-backed programs commonly require a personal guarantee from anyone holding a meaningful ownership stake in the borrowing company. Guarantees are occasionally waived or reduced for established businesses with long operating history, strong financials, or hard assets the lender can secure against instead.
Does a personal guarantee show up on your personal credit report in Canada?
Not when you sign it. A guarantee is a contingent promise rather than a credit account in your name, so it is not reported to Equifax Canada or TransUnion Canada at closing. If the business defaults and the lender enforces the guarantee, the resulting collections activity, court judgment or settled balance can appear on your personal file and affect your score for years.
Can you get out of a personal guarantee after you have signed it?
Sometimes, and timing decides it. Under section 21 of the Canada Small Business Financing Regulations, a lender may release a guarantor only while the loan is in good standing. The practical route is substitution under section 22: with the lender's consent you replace the guarantee with security in business assets or another guarantee of equal or greater value.
Does incorporating protect you from a personal guarantee?
No. A corporation limits your exposure to creditors whose only claim is against the company itself. A guarantee is a separate contract between you and the lender, and it survives the corporation. If the company is wound up or goes bankrupt, the lender can still pursue you personally on the strength of that signature.
What is the difference between a limited and an unlimited personal guarantee?
An unlimited guarantee exposes you to the entire outstanding balance plus interest, enforcement costs and legal fees, with no ceiling. A limited guarantee names a maximum, either as a dollar figure or as a percentage of the original loan. Always ask whether costs and interest sit inside that maximum, because in most agreements they sit outside it.
Do alternative lenders in Canada require personal guarantees?
Usually yes, including on merchant cash advances and short-term working capital facilities. What varies is the structure. Because alternative underwriting weighs revenue and deposit history rather than the credit score alone, there is often more room to negotiate the ceiling, the release trigger, and whether liability is joint and several.
