Refinancing your mortgage after a divorce in Ontario usually means using a Spousal Buyout Program to borrow up to 95% of your home's appraised value, far above the standard 80% refinance ceiling, so you can pay your former spouse their share of the equity and take sole ownership. You must qualify on your own income under the 2026 mortgage stress test, have a signed separation agreement, and ensure both spouses are on title at separation.

How Refinancing a Mortgage After Divorce Works in Ontario
Refinancing your mortgage after divorce in Ontario typically requires a Spousal Buyout Program that lets you borrow up to 95% of the home's appraised value, compared to the 80% limit on a conventional refinance. This 15-percentage-point increase gives you the cash to pay your ex-spouse their equity share and remove them from both title and the mortgage in a single transaction.
When you refinance to buy out a spouse, the lender treats the transaction like a purchase rather than a standard refinance. The equity you pay to your former spouse functions as the down payment. For example, on a home appraised at $600,000, a 95% spousal buyout mortgage advances up to $570,000, while a conventional 80% refinance would cap your borrowing at $480,000, a $90,000 difference. That gap is often what determines whether removing your spouse from the mortgage is financially possible or whether you must sell the home instead. The Spousal Buyout Program is backed by Canada's three mortgage default insurers, so brokers, not all retail bank branches, generally arrange it.
The Spousal Buyout Program: Borrow Up to 95% of Home Value
The Spousal Buyout Program allows one divorcing spouse to refinance the matrimonial home up to 95% of its appraised value to buy out the other spouse, versus the 80% maximum on a standard refinance. All three Canadian mortgage insurers, CMHC, Sagen, and Canada Guaranty, offer a version of this insured mortgage, which is structured as a purchase transaction rather than a refinance.
The program exists because a buyout spouse rarely has 20% equity sitting idle to fund the payout. Consider a home worth $500,000 with a $250,000 existing mortgage, leaving $250,000 in equity split equally at $125,000 each. To buy out your spouse under a conventional 80% refinance, you could borrow only $400,000, leaving $150,000 to pay $125,000 plus closing costs, which is tight. Under the 95% spousal buyout, you can borrow up to $475,000, comfortably covering the $125,000 payout, the existing mortgage, and matrimonial debts named in the separation agreement. Because the new loan exceeds 80% loan-to-value, mortgage default insurance applies, and the premium is usually added to the mortgage balance rather than paid upfront.
Removing a Spouse From the Mortgage and Title
Removing a spouse from the mortgage in Ontario requires both a title transfer and a new mortgage in your name alone, because taking a name off title does not release that person from mortgage liability. A separation agreement saying your ex "keeps the house" does not end your obligation to the lender; only the lender, through refinancing or an approved assumption, can release a borrower.
Many separating spouses wrongly assume that moving out or signing a separation agreement automatically ends their mortgage liability. In reality, the original lender continues to hold both spouses responsible until the loan is refinanced, assumed with lender approval, or paid off through a sale. To complete removing your spouse from the mortgage, the buyout spouse refinances into a new mortgage, the leaving spouse signs a transfer of their title interest, and a real estate lawyer registers the change. Both spouses must be on title at the date of separation to use the Spousal Buyout Program. Under Family Law Act § 21, you cannot mortgage or sell the matrimonial home without your spouse's written consent or a court order, so the buyout documents must include that consent.
The 2026 Mortgage Stress Test and Qualifying Alone
The 2026 mortgage stress test requires you to qualify at the greater of your contract rate plus 2% or the benchmark rate of 5.25%, and this single-income hurdle is where most divorce refinances succeed or fail. A spouse who qualified easily on two incomes during the marriage must now prove they can carry the larger buyout mortgage on their own earnings.
Federally regulated lenders apply the stress test to every spousal buyout mortgage, treating it as a fresh purchase qualification. If your contract rate is 4.5%, you must demonstrate you can afford payments at 6.5% (4.5% + 2%), since that exceeds the 5.25% floor. Support payments change the math in two directions: if you pay spousal or child support, lenders count it as a debt that reduces your borrowing capacity; if you receive support, documented and stable payments may count as qualifying income within insurer guidelines. To strengthen your file, gather pay stubs, notices of assessment, and a copy of the separation agreement showing support amounts. If your income alone cannot support the buyout mortgage at the stress-test rate, alternatives include a co-signer, alternative lenders capped at 80% LTV, or selling the home.
How the Matrimonial Home Is Divided Under Ontario Law
Ontario divides property through equalization of Net Family Property under the Family Law Act, and the matrimonial home receives unique treatment: its full separation-date value is included in the owner's property with no deduction for its marriage-date value. This rule frequently produces a larger payout to the non-owning spouse and directly affects how much equity you must finance in a buyout.
Under Family Law Act § 5, each spouse calculates net worth at the separation date minus net worth at the marriage date; the spouse with the higher Net Family Property pays half the difference to the other as an equalization payment. The matrimonial home breaks the normal pattern. If one spouse brought a $200,000 home into the marriage that became the matrimonial home and it is worth $300,000 at separation, that spouse cannot deduct the $200,000 marriage-date value, exposing the full $300,000. Inheritances or gifts invested in the matrimonial home also lose their normal exemption. The deadline to claim equalization is the earliest of six years from separation, two years from a divorce judgment, or six months after the other spouse's death.
What the Refinance Funds Can and Cannot Pay
Under a Spousal Buyout Program refinance, the funds can pay your former spouse's equity share, and depending on the insurer, can also clear joint matrimonial debts and mortgage penalties specified in the separation agreement. The exact rules differ between CMHC and the other insurers, so the separation agreement must list every debt and amount to be paid.
The insurer you use determines flexibility. CMHC's Spousal Buyout Program restricts the borrowed funds to paying out the spouse's equity only, not other debts or penalties. Sagen (formerly Genworth) permits the refinance funds to pay off matrimonial debts and mortgage prepayment penalties, provided those items appear in the separation agreement. This is why lenders insist the agreement explicitly state the equity payout figure, the specific joint debts to be cleared, and closing costs, because the lender advances funds based on that document. Budget separately for prepayment penalties when breaking an existing mortgage early: variable-rate mortgages typically carry a three-months'-interest penalty, while fixed-rate mortgages cost the greater of three months' interest or the interest rate differential, which can reach thousands of dollars.
Land Transfer Tax Exemption on a Spousal Buyout
A matrimonial home transfer between spouses is exempt from Ontario Land Transfer Tax when it complies with a written separation agreement or court order, under Regulation 696, R.R.O. 1990 made under the Land Transfer Tax Act. This exemption can save thousands of dollars when transferring title during a buyout, but the agreement documentation must be precise.
The exemption applies in three situations: when the only consideration is assuming a registered mortgage; when the transfer complies with a written separation agreement under which the parties agree to live separate and apart; or when the transfer follows a court order. Critically, the buyout payment for your spouse's interest can still qualify for the exemption if it is specified in the separation agreement, even though a buyout payment would otherwise count as taxable consideration. The transferor and transferee must be spouses or former spouses as defined in Family Law Act § 29. At registration, your lawyer selects statements 9085 and 9087 under the exemption tab and cites Regulation 696 in the affidavit. On a $600,000 Toronto home, this exemption can avoid roughly $8,475 in provincial plus a similar municipal land transfer tax, so confirm eligibility with your real estate lawyer before changing title.
Alternatives if You Cannot Refinance
If you cannot qualify to refinance the mortgage after divorce in Ontario, the main alternatives are mortgage assumption, alternative lending capped at 80% loan-to-value, or selling the home and dividing the proceeds. Each option has a different cost, qualification standard, and impact on your equity, so compare them before deciding.
Mortgage assumption lets one spouse take over the existing mortgage and its rate, which can save refinancing costs and avoid prepayment penalties, but the lender must approve the assuming spouse on income, debt ratios, and credit. Alternative financing through B-lenders or private lenders is available up to 80% of the home's value if you cannot meet insured-program criteria, though rates and fees run higher. Selling the matrimonial home provides the cleanest exit: sale proceeds pay off the mortgage, cover real estate commissions and legal fees, and the remaining equity is split according to the separation agreement. A typical Ontario home sale costs roughly 4-5% in real estate commission plus $1,500-$2,500 in legal fees. Run the numbers on all three paths with a mortgage broker and family lawyer before committing.
