Mortgages After Divorce or Separation in Canada
Getting a mortgage after divorce in Canada: how lenders treat support payments, single-income qualification, buy-outs, refinancing, and the stress test.
A mortgage after divorce or separation in Canada usually means one of three things: buying out your ex's share of the home, qualifying for a new mortgage on your own income, or selling and dividing the proceeds. Lenders assess you as an individual borrower — your income, your debts, your credit — not as a household. The federal mortgage stress test, GDS and TDS ratios, and CMHC default insurance rules all still apply, so the smartest move is to map out your options before you finalize anything.
How separation changes your mortgage file
When you bought together, the lender looked at combined income and combined debts. After a separation, only your income is counted, while joint debts can still sit on your credit report. A joint mortgage, joint car loan, or joint credit card typically appears on both credit reports, and most lenders count the full balance and the full payment against you until your name is formally removed.
That is why documentation matters as much as income. A written separation agreement or court order that records who keeps the home, who pays the mortgage, and how support is handled gives lenders something concrete to underwrite. Informal arrangements usually cannot be used.
Your three main options
| Option | What it involves | What to watch |
|---|---|---|
| Buy out your ex | You refinance or take a new mortgage in your name and pay your ex for their share of equity | You must qualify on your own income, and a payout penalty may apply to the old mortgage |
| Sell the home | Both names come off title, the mortgage is discharged, and net proceeds are divided as agreed | Early payout penalty, legal and discharge fees, and a fresh land transfer tax bill when either of you buys again |
| Assume the mortgage | One borrower is released and the other keeps the existing mortgage | The lender must agree and may require the remaining borrower to re-qualify in full |
Income, support payments, and your ratios
Lenders measure affordability with two ratios. Gross debt service (GDS) compares housing costs to gross income, and total debt service (TDS) adds all other debt payments. When your income drops after separation, your ratios tighten quickly, which is why the details of support matter.
Child support and spousal support you receive can often be added to your qualifying income if the arrangement is documented and expected to continue — lenders typically want a separation agreement, a court order, or a reliable deposit history. Support you pay is treated like a debt and reduces how much you can carry. Lenders vary in how strictly they apply each rule, so confirm the treatment with yours. See the guide to GDS and TDS ratios for the math.
The stress test and default insurance still apply
You qualify at the higher of your contract rate plus two percentage points or the published qualifying-rate floor. Confirm the current floor with OSFI or your lender before you assume a number. You can test scenarios with the stress test explainer.
If your down payment is under 20% of the purchase price, mortgage default insurance from CMHC or a private insurer is required, and insured mortgages carry their own loan-to-value and amortization limits. If you are refinancing a home you already own rather than buying, that is a different product with different limits.
Refinancing to buy out your ex
Keeping the home usually means refinancing so the mortgage sits in your name alone, then paying your ex their share of the equity. A refinance typically allows borrowing up to 80% of the home's appraised value, and you will need enough equity to cover both the buy-out and closing costs.
Paying out the old mortgage early can trigger a prepayment penalty. On a closed fixed-rate mortgage that penalty is often the greater of three months' interest or the interest rate differential (IRD), which can be substantial when rates have fallen since you signed. The guides to the IRD and refinancing a mortgage explain how the numbers work. Some lenders also offer dedicated spousal buy-out programs that allow a higher loan-to-value ratio than a standard refinance when a separation agreement is in place — ask your lender whether that option exists and what it requires.
Credit, title, and the details people miss
- Close or separate joint accounts. A joint credit card or line of credit keeps counting against your ratios even if your ex is the one paying it.
- Transfer the title. Removing a name from title is a legal step, usually handled by a lawyer or notary. Some provinces offer relief from land transfer tax on transfers between spouses under a separation agreement — check your province's rules.
- Look at first-time buyer programs. After a relationship breakdown, the CRA may treat you as a first-time home buyer for the RRSP Home Buyers' Plan and the First Home Savings Account. Confirm current eligibility on the CRA website.
- Update beneficiaries and insurance. Life insurance, wills, and powers of attorney usually need revisiting after a separation.
Documents to have ready
Expect to provide a signed separation agreement or court order, proof of any support received, recent pay stubs and T4s, Notices of Assessment, the current mortgage statement, a property tax bill, photo ID, and a void cheque. Pulling a full credit report helps you spot joint accounts you forgot about. See the mortgage document checklist for the full list.
Start with the numbers, not the draft agreement
Before you finalize anything, find out what you can actually qualify for on one income. Run your income, debts, and down payment through the mortgage affordability calculator, then speak with a lender or mortgage broker about how they treat support payments and buy-outs. Knowing your number first keeps you from agreeing to a settlement you cannot finance.
Frequently asked questions
Can I get a mortgage after divorce on one income?
Yes, but you qualify on your own income, debts, and credit rather than a combined household figure, which usually means a smaller maximum mortgage. Lenders apply the same stress test and GDS/TDS ratios as any other applicant. If you receive documented child or spousal support, ask whether your lender will add it to qualifying income, since that can meaningfully increase what you can borrow.
Does child support count as income when applying for a mortgage?
Often it can, if the support is documented and expected to continue. Lenders typically want a separation agreement or court order and may ask for a deposit history showing regular payments. Support you pay is usually treated as a debt and lowers your borrowing room. Rules differ between lenders, so confirm how yours treats both received and paid support before you rely on it.
Do I need a separation agreement to get a mortgage after separation?
In most cases, yes. Lenders want written proof of the arrangement, such as a signed separation agreement or court order, especially when you are buying out a former partner or relying on support income. A verbal agreement is rarely accepted. If your divorce is not yet finalized, a separation agreement is usually enough; ask your lender exactly what documentation it requires.
How do I remove my ex's name from the mortgage?
Removing a name is not automatic. The lender must approve the change and will usually require the remaining borrower to re-qualify for the full mortgage balance. This typically happens through an assumption or a refinance, and there may be a prepayment penalty plus legal and title-transfer costs. If the lender declines, selling the home and discharging the mortgage is often the alternative.
