What happens if the person I co-signed for doesn''t pay?

You become 100% responsible for the full debt. The lender can demand payment from you without first trying to collect from the primary borrower. Missed payments will appear on your credit report, and the lender can sue you, garnish your wages, or seize your assets to recover the money.

Can I remove myself as a co-signer?

It is very difficult. Most lenders will not release a co-signer unless the primary borrower refinances the loan on their own or pays it off. Some lenders allow co-signer release after 12-24 months of on-time payments, but this is not guaranteed. Get the co-signer release policy in writing before signing.

Does co-signing affect my ability to get a mortgage?

Yes. The co-signed loan appears on your credit report as your debt. Lenders include it in your debt-to-income ratio when you apply for a mortgage, potentially reducing how much you qualify for or disqualifying you entirely.

Co-Signing a Loan in Canada: Risks, Responsibilities, and Alternatives (2026)

Co-signing a loan in Canada means you are legally agreeing to pay the full debt if the borrower doesn’t. That’s not a theoretical risk — according to industry data, a significant percentage of co-signed loans end up in default, with the co-signer left holding the bill. Before signing, understand that you are taking on 100% of the risk in exchange for 0% of the benefit. There are almost always better alternatives that help the borrower without jeopardizing your own finances.

What Co-Signing Means

Aspect	What It Means for You
Legal obligation	You are equally responsible for the full debt
Credit reporting	Loan appears on your credit report
Payment default	Lender can come to you immediately for full amount
Credit impact	Late payments affect your credit score
Debt-to-income	Counts against you for future borrowing
Duration	Until the loan is fully paid off or you’re released

Co-Signer vs Guarantor

Most people use these terms interchangeably, but they carry different legal weight. A co-signer is equally responsible from day one — the lender can come to you for payment even before contacting the primary borrower. A guarantor is a backup: the lender must first attempt to collect from the borrower and only comes to you after they’ve defaulted. If you must help someone borrow, being a guarantor is the less risky option, though not all lenders offer the distinction.

	Co-Signer	Guarantor
Obligation	Primary — equally responsible	Secondary — responsible only after borrower defaults
When lender contacts you	Anytime, even before contacting borrower	After borrower has defaulted and lender has attempted collection
Credit report	Loan appears on your report	May or may not appear on your report
Common for	Personal loans, car loans, credit cards	Mortgages, rental agreements, student lines of credit

Before You Co-Sign: Checklist

Question	If the Answer Is No…
Can I afford to pay this loan if they can’t?	Don’t co-sign
Do I trust this person’s financial habits?	Don’t co-sign
Am I okay losing this relationship if things go wrong?	Don’t co-sign
Have I seen their budget and financial situation?	Ask before signing
Is there a co-signer release clause?	Negotiate one or reconsider
Will this affect my own borrowing plans?	Calculate the impact first
Have I read the full loan agreement?	Read every page before signing

How to Protect Yourself If You Co-Sign

Protection	How
Get co-signer release clause in writing	Some lenders release after 12-24 months of on-time payments
Set up payment alerts	Ask lender to notify you of any missed payments
Monitor your credit report	Check monthly for the co-signed account
Keep copies of everything	Loan agreement, payment history, communications
Written agreement with borrower	Not legally binding against lender, but clarifies expectations
Cap the amount	Co-sign the minimum needed, not more
Set a time limit	Agree that borrower refinances within a set period

Alternatives to Co-Signing

Before co-signing, consider whether one of these alternatives achieves the same goal with less risk. Helping with a larger down payment reduces the loan amount without tying your credit to someone else’s payments. A secured credit card lets the borrower build credit using their own cash as collateral. Adding them as an authorized user on your credit card helps their credit score without making you liable for a separate debt.

Alternative	Details
Help with a down payment	Gift money to reduce the loan amount
Secured credit card	Borrower deposits cash as collateral
Credit-builder loan	Small loan designed to build credit (no co-signer needed)
Become an authorized user	Add them to your credit card (you control the account)
Delayed purchase	Wait until they’ve built enough credit
Credit union	Often more flexible lending criteria
Joint account vs co-signing	Different legal structure, consider carefully

How to Remove Yourself as a Co-Signer

Method	Likelihood of Success
Borrower refinances on their own	Best option — completely removes you
Co-signer release clause	If the lender offers it (after on-time payments)
Pay off the loan	Eliminates the obligation
Negotiate with lender	Difficult, but worth trying
Sell the asset	If it’s a car loan, selling the car can pay off the loan
Bankruptcy (yours)	May discharge obligation, but destroys your credit

What does NOT remove you:

Action	Removes You?
Verbal agreement with borrower	No
Divorce decree	No (lender is not bound by divorce agreements)
Borrower says they’ll take over	No (only lender can release you)
Closing your other accounts	No
Moving provinces	No

The Bottom Line

Co-signing is one of the highest-risk financial decisions you can make. You get no benefit from the loan, but you take on full liability for the debt, and your credit and borrowing capacity are affected as if the debt were your own. If you do co-sign, insist on a written co-signer release clause, set up payment alerts so you know immediately if a payment is missed, and monitor your credit report monthly.
