Debt and Divorce in Canada: Who Owes What When a Marriage Ends (2026)

Your separation agreement says your ex is responsible for the joint Visa card. Your ex hasn’t paid it in four months. Your credit score just dropped 90 points, and the collection calls are coming to your number. Welcome to one of the most misunderstood financial realities of divorce in Canada: a separation agreement does not bind your creditors. The creditor was not in the room when that agreement was signed. They are not obligated to honour it. Both names on the account remain legally liable until the debt is paid, refinanced, or discharged through insolvency — regardless of what a family court orders.

According to Statistics Canada, approximately 38% of Canadian marriages end in divorce. The average separating couple carries a combined debt load of $75,000 to $100,000. Knowing exactly who owes what — and what actually protects you — is not optional. It is financial survival.

The Separation Agreement Trap: What It Does and Doesn’t Do

A separation agreement is a contract between you and your spouse. It allocates financial responsibility. A court order is enforceable between the two of you. Neither document binds a third-party creditor.

Here is what this means in practice:

What a separation agreement CAN do:

• Establish which spouse is responsible for which debt between the two of you
• Give you the legal right to sue your ex if they default on a debt assigned to them
• Form the basis of a contempt-of-court application if your ex violates a court order

What a separation agreement CANNOT do:

• Remove your name from a joint credit account without the creditor’s consent
• Release you from liability on a joint mortgage without the lender refinancing in one name
• Prevent a creditor from reporting missed payments against both parties
• Stop collection calls to you for a joint debt your ex was ordered to pay

Jennifer and David separated in Toronto after 12 years of marriage. Their separation agreement assigned David full responsibility for the $34,000 joint line of credit. David made payments for eight months, then lost his job. The bank sent collection notices to both of them — Jennifer’s name was still on the account. Jennifer’s credit score fell 115 points. The bank told her she was equally liable and could pursue David privately through the courts. She spent $8,000 in legal fees recovering funds from David — while paying interest on a debt she was “no longer responsible for.”

Joint vs. Individual Debt: Who Actually Owes What

The most dangerous assumption in divorce is that because you “agreed” something in a separation agreement, the creditor is bound. They are not. The only way to actually remove your name from a joint debt is to get the creditor to agree in writing.

“The number one thing I see in my practice is people who thought their separation agreement protected them from their ex’s debts. It doesn’t protect you from the creditor. It only gives you a right to sue your ex after the fact — after your credit is already damaged and the collection calls have already started.” — Licensed Insolvency Trustee, Ontario

Credit Cards: The Joint Account Problem

When you hold a joint credit card, both parties are jointly and severally liable — meaning each of you is responsible for 100% of the balance, not just 50%. If your ex stops paying, you owe the full amount.

Steps to protect yourself on joint credit cards at separation:

1. Request a balance snapshot. Get the current balance in writing from the card issuer before you separate finances.
2. Pay off and close the joint account. If possible, pay the balance to zero and request the account be closed.
3. Refinance the balance into individual accounts. Each spouse takes their allocated share as a solo balance transfer or personal loan.
4. Remove authorized users immediately. An authorized user is not liable for the debt, but they have access to the credit line and can run up the balance.
5. Document everything. If you make any payments on a joint card after separation, keep records — you may need to recover those funds.

If you cannot afford to pay off the joint card and your ex controls the account, your options narrow significantly. You can request that the card issuer close the account to new charges (this does not remove the existing balance obligation), or you can file individually through a Licensed Insolvency Trustee to include your liability in a consumer proposal.

What Happens to the Mortgage When You Separate

The mortgage is usually the largest joint debt and the most complex to unwind.

Option 1: One spouse buys out the other. The spouse keeping the home applies to refinance the mortgage in their name alone. The lender conducts a fresh qualification — if the keeping spouse cannot qualify solo, the other spouse remains on the mortgage indefinitely.

Option 2: The property is sold. The mortgage is discharged, equity is divided per the separation agreement, and both parties start fresh. This is the cleanest outcome for eliminating the joint liability.

Option 3: Co-ownership continues post-separation. Common when the market is unfavourable or children are in school. Both parties remain on the mortgage and both are liable for every payment. A missed mortgage payment damages both credit scores.

Mortgage stress testing in 2026 has tightened considerably — lenders are declining approximately 38% more renewal applications than in 2024, according to the Canada Mortgage and Housing Corporation. A spouse who could not qualify for a mortgage solo during the marriage is even less likely to qualify on a single income post-separation.

CRA Tax Debt and Divorce

Each spouse files their own income tax return in Canada. Individual tax debt is each person’s sole responsibility. However, complications arise in two common scenarios:

Business income splitting. If you and your spouse jointly operated a business and CRA reassesses income splitting arrangements, both may face tax liability.

GST/HST credits and benefit overpayments. If your household income changed at separation but you continued receiving credits calculated on the pre-separation combined income, CRA may claw back overpayments. Both spouses may face individual clawback demands.

Joint tax elections. If you elected to split pension income or made other joint tax elections, unwinding those at separation may trigger retroactive tax adjustments.

CRA debt from your ex’s individual tax filings is their problem alone — CRA cannot pursue you for another person’s individual income tax arrears.

What Happens If Your Ex Stops Paying a Joint Debt

The timeline is faster and more damaging than most people expect:

A single 90-day late payment drops the average credit score by 90 to 110 points, according to credit bureau data. Multiple accounts in default simultaneously can drive a score from 720 to below 580 within 90 days — moving the damaged spouse from prime to subprime lending territory.

Can a Consumer Proposal Protect You From Divorce Debt?

Yes — and it is often the most effective tool available when joint debts are unmanageable and your ex is not cooperating.

A consumer proposal is a legal agreement between you and your creditors, filed through a Licensed Insolvency Trustee. It can include:

• Your liability on joint credit cards and lines of credit
• Personal loans, individual credit cards, and other unsecured debts
• Your portion of any joint debts where you are a co-borrower

What a consumer proposal does immediately upon filing:

• Legal stay of proceedings — all collection calls, lawsuits, and wage garnishment attempts stop
• Interest freeze — no further interest accrues on included debts
• Credit score protection from further damage — the stay prevents new adverse reporting

Your ex’s debts are their own problem. Your proposal only covers your liability. If the joint credit card has a $25,000 balance, your proposal addresses your co-borrower obligation — your ex still owes their share unless they also file.

Use the consumer proposal calculator to estimate what your monthly payment might be, or read the detailed comparison of consumer proposal vs. bankruptcy to understand both options.

How to Protect Your Credit During Separation

Start these steps immediately upon deciding to separate — before legal proceedings begin:

1. Pull your credit reports from both bureaus. Get your Equifax report via Borrowell (free) and your TransUnion report directly. Document the baseline before any accounts go delinquent.
2. List every joint account. Credit cards, lines of credit, car loans, mortgage, personal loans. Note the balance, payment status, and both account holders.
3. Remove your ex as authorized user on your individual cards. An authorized user is not liable but has spending access. Remove them immediately.
4. Open individual accounts in your name only. You need your own banking relationship and credit before the joint accounts close.
5. Set up payment alerts on all joint accounts. If your ex misses a payment, you want to know the day it happens — not 90 days later.
6. Consult a Licensed Insolvency Trustee if debts are unmanageable. The consultation is free. If the combined marital debt load is impossible on a single income, a consumer proposal may be the cleanest exit.

Bankruptcy During Divorce: Can Spouses File Separately?

Yes. Spouses are separate legal entities and file insolvency proceedings independently. You do not need your ex’s consent or cooperation to file a consumer proposal or bankruptcy. Your filing does not trigger your ex’s filing.

However, timing matters. If a joint debt is included in your consumer proposal, your ex still owes their portion — and may face collection activity on that portion. If the relationship with your ex is cooperative, coordinating the timing of filings can produce a cleaner outcome. If it is not, your protection is not contingent on their cooperation.

Your Next Step

If separation has left you holding joint debts your ex is no longer paying, or if the combined debt load is unmanageable on a single income, the cost of waiting is measured in missed payments and credit score damage that takes years to repair.

A Licensed Insolvency Trustee will review your situation for free and tell you exactly what a consumer proposal would cost — and how much debt it would eliminate. The consultation is confidential and carries no obligation. Most people who come in leave with a clear number and a clear path forward.
