Ontario Debt Division Calculator

Ontario uses equalization of net family property (NFP) under the Family Law Act, RSO 1990, c. F.3, Section 4—not community property or equitable distribution. Each spouse calculates their NFP by subtracting all debts from assets at separation, minus their net worth at marriage. The spouse with higher NFP pays half the difference to the other spouse, effectively sharing the debt burden through this equalization payment.

In Ontario, you are only legally responsible to creditors for debts you co-signed, co-borrowed, or guaranteed. Marriage alone does not make you liable for your spouse's individual debts. However, during divorce, your spouse's debts reduce their net family property, which can increase the equalization payment you receive—or decrease what you owe. Debts your spouse brought into the marriage remain their sole responsibility.

Joint credit cards in Ontario create joint and several liability, meaning both spouses are 100% responsible for the full balance to the creditor—not just half. Supplementary cards typically leave only the primary cardholder liable. Individual credit cards in one spouse's name reduce that spouse's NFP in equalization. After separation, immediately freeze joint accounts to prevent new charges while continuing payments.

Student loans in Ontario generally remain with the borrowing spouse, as only the original borrower is liable to the creditor. However, student loan debt acquired during marriage reduces that spouse's net family property in the equalization calculation, which can affect your equalization payment. If you co-signed your spouse's student loan, you share full liability to the lender regardless of what your separation agreement states.

The matrimonial home mortgage in Ontario factors into the spousal buyout calculation: equity equals appraised value minus mortgage balance, typically split 50/50 in the separation agreement. CMHC's spousal buyout program allows refinancing up to 95% of the home's value, helping the staying spouse pay out their ex-partner. The departing spouse must be removed from the mortgage—simply assigning it in the separation agreement does not release them from lender liability.

Yes, creditors can pursue you for any joint debt regardless of what your Ontario separation agreement states. Separation agreements divide responsibility between spouses, but creditors are not parties to your divorce—they retain full rights under the original credit agreement. If your ex-spouse stops paying a joint debt assigned to them, the lender can legally collect the entire balance from you. To eliminate this liability, the creditor must consent to remove your name from the account.

Medical debt in Ontario is included in net family property calculations like other debts incurred during marriage. Canada's healthcare system covers most hospital care, but private medical expenses reduce the owing spouse's NFP. Courts may consider each spouse's ability to pay when medical debt significantly impacts equalization. Medical debt your spouse brought into the marriage or incurred after separation typically remains their individual responsibility.

Timing bankruptcy around Ontario divorce requires careful consideration. Filing before divorce means your spouse's income counts toward surplus income calculations, potentially increasing costs. Filing after divorce excludes their income and protects assets transferred via Family Court Order from creditors. However, if you file bankruptcy, creditors will pursue your ex-spouse for 100% of any joint debts. Equalization payments owed to your spouse may be dischargeable, but spousal and child support obligations survive bankruptcy.
