Executing a spousal buyout mortgage in Ontario typically takes 30 to 60 days. To buy out your ex-partner, you must have a finalized separation agreement and qualify for refinancing. Special CMHC, Sagen, or Canada Guaranty rules allow you to finance up to 95% of the matrimonial home’s value to keep the property.
One of the most stressful decisions during a divorce is figuring out what happens to the matrimonial home. For many Ontario families, uprooting children and selling the house is the last resort. If one spouse wants to stay and keep the property, they must buy out the other spouse’s share of the equity. However, you cannot simply cross a name off the deed and carry on; you must legally and financially restructure the debt.
A spousal buyout mortgage is a specific type of refinancing designed for divorcing couples. Normally, Canadian banking rules restrict you from refinancing more than 80% of your home’s value. However, under specialized spousal buyout programs offered by default mortgage insurers like CMHC, Sagen, or Canada Guaranty, a remaining spouse can access up to 95% of the home’s equity. This allows them to pay off the departing partner, discharge joint first mortgages, and depending on the insurer selected, consolidate other family liabilities to secure a fresh financial start.
Step-by-Step Process in Ontario
Whether your home is located in Kingston, Kitchener, Barrie, Toronto, or Mississauga, the spousal buyout process requires intense coordination between your family lawyer, your mortgage broker, and your real estate lawyer. Following these steps sequentially is crucial to ensure the transaction closes smoothly and both parties are legally protected.
Step 1: Signing a Legal Separation Agreement
You cannot even apply for a spousal buyout mortgage without a legally binding, finalized Separation Agreement. Lenders need absolute certainty about your financial obligations. The agreement must explicitly state who is keeping the house, exactly how much equity the departing spouse is entitled to, and outline any ongoing spousal support or child support payments, as these drastically affect your mortgage qualification.
Step 2: Appraising the Matrimonial Home
To determine how much equity needs to be split, you must know what the house is worth today. A professional, independent appraisal is almost always required by the mortgage lender. You and your ex-spouse should agree on a certified appraiser. If the house is valued at $800,000 and your current mortgage is $400,000, there is $400,000 in equity to deal with.
Step 3: Applying for the Refinance (Qualifying)
The spouse keeping the home must now apply for a new mortgage solely in their name. You will need to prove to the lender that your single income is sufficient to carry the new, larger mortgage. If you receive regular spousal support or child support, lenders can often include that as qualifying income, provided there is a formal court order or separation agreement backing it up.
Step 4: Obtaining Independent Legal Advice (ILA)
In Ontario, it is standard practice (and often mandatory) for both spouses to receive Independent Legal Advice (ILA) from separate law firms before the title transfer is executed. This proves that the departing spouse fully understands they are giving up their rights to the matrimonial home in exchange for the agreed-upon cash buyout, preventing future lawsuits.
Step 5: Closing with a Real Estate Lawyer
Once the lender approves the spousal buyout mortgage, your real estate lawyer handles the closing day. The lawyer will receive the funds from the bank, pay off the old joint mortgage, pay out the departing spouse’s equity share directly into their bank account, and register the new property title solely in your name at the Land Registry Office.
How Much Does it Cost in Ontario?
Refinancing a home is not free. Both spouses need to budget for the administrative and legal costs associated with transferring title and securing new debt. Below are average estimated costs in CAD as of May 2026.
| Home Appraisal Fee | $350 – $600 CAD |
| Family Lawyer (Separation Agreement) | $2,500 – $5,000+ CAD |
| Mortgage Break Penalty (Old Mortgage) | Varies (Often $2,000 to $10,000+) |
| Real Estate Lawyer Closing Fees | $1,200 – $1,800 CAD |
How Long Does the Process Take?
Assuming you already have a signed Separation Agreement in hand, the actual mortgage process is quite fast. Booking an appraiser and receiving the report takes about 1 week. The lender’s underwriting process to approve the new default-insured mortgage takes roughly 1 to 2 weeks. Finally, your real estate lawyer needs about 2 weeks to draft the transfer documents, clear title, and execute the closing. In total, expect the refinancing phase to take 30 to 60 days.
Frequently Asked Questions (FAQ)
Do I have to pay Land Transfer Tax when buying out my spouse?
Generally, no. In Ontario, transferring property between legally married spouses or common-law partners pursuant to a written separation agreement is usually exempt from provincial Land Transfer Tax. Your real estate lawyer will file the appropriate exemption forms on closing.
Can I use the buyout mortgage to pay off our credit cards?
It depends on the insurer. Under CMHC guidelines, the proceeds of a spousal buyout mortgage can only be used to pay off the existing joint first mortgage and fund the departing spouse’s equity payout; they cannot be used to consolidate other debts or cover mortgage prepayment penalties. However, if you insure the mortgage through private default insurers Sagen or Canada Guaranty, you are permitted to roll joint marital debts (like credit cards, lines of credit, or car loans) and penalties into the new mortgage up to the 95% limit, provided these obligations are explicitly detailed in your signed Separation Agreement.
What happens if I don’t qualify for the new mortgage on my own?
If your single income is too low to support the new debt, the lender will deny the application. At that point, you usually have two options: find a suitable co-signer (like a parent) to guarantee the mortgage, or list the matrimonial home for sale and split the cash proceeds.
When does my ex-spouse have to move out?
This should be explicitly detailed in your separation agreement. Generally, the departing spouse is expected to vacate the property on or before the legal closing date, which is when they receive their lump-sum equity payout from the real estate lawyer.
