A Guide to Your Mortgage During a Divorce in Ontario
August 9, 2025

Divorce or separation is undeniably one of the most stressful and emotionally taxing life events a person can go through. While you’re navigating the personal challenges, you’re also forced to make critical and complex financial decisions under immense pressure. The largest and most emotionally charged of these is almost always what to do with the matrimonial home and its mortgage. It's not just a financial asset; it's a home filled with memories, and its future is often a major point of contention.
This guide is designed to provide a clear, calm, and practical overview of the mortgage options available to separating couples in Ontario. Our goal is to demystify the process, explain the terminology, and show you that there is a path forward to a stable and independent financial future. While this is expert financial guidance, it is essential that it is paired with professional legal advice from your family lawyer, who will help you navigate the legal framework for separating your assets.
The First Step: The Matrimonial Home
Before any decisions can be made about the mortgage, both parties must understand the legal status of their property.
What Qualifies as a Matrimonial Home?
Under Ontario's Family Law Act, the matrimonial home is the property that you and your spouse ordinarily occupied as your family residence at the time of separation. It’s important to note that a couple can have more than one matrimonial home (for example, a house in the city and a family cottage).
The most critical rule regarding the matrimonial home is that both spouses have an equal right to possess it, regardless of whose name is on the legal title. Even if only one spouse is on the title to the property, the other spouse has a legal right to live there until a court order or a formal separation agreement states otherwise. This "possessory right" protects both partners from being suddenly locked out of their home. Conversely, an investment property purchased during the marriage that the couple never lived in would not typically be considered a matrimonial home, and would be treated differently in the division of assets.
The Importance of the Separation Agreement
No lender will even begin to look at a mortgage application for a separating couple until a legally binding Separation Agreement is drafted and signed. This document, prepared by your lawyers, is the absolute foundation of the entire process.
The separation agreement will explicitly state how the home's equity is to be divided, who has the right to buy out the other, and by what date these actions must take place. It is the non-negotiable instruction manual that we, as mortgage brokers, and the lenders must follow. It removes all ambiguity and provides the legal certainty needed to proceed with any financing.
The 3 Main Options for the Mortgage
Once a Separation Agreement is in place, there are generally three paths you can take to handle the existing mortgage and the property.
Option 1: One Spouse Buys Out the Other
This is often the most desired outcome, especially when children are involved, as it allows one parent and the children to remain in the family home, providing a sense of stability during a difficult time.
The Goal: The spouse who is staying in the home (let's call them Spouse A) must pay the other spouse (Spouse B) their share of the home's equity. To do this, Spouse A will need to refinance the mortgage.
The Process: It’s a multi-step process. First, you must get a formal appraisal of the home to determine its current, fair market value. Then, you calculate the total equity (Appraised Value - Mortgage Balance = Equity). Your Separation Agreement will define the exact buyout amount, which is typically 50% of the equity. Finally, Spouse A applies for a new mortgage that is large enough to pay off the old mortgage and pay out the full buyout amount to Spouse B.
The Challenge: The biggest hurdle is that Spouse A must now qualify for this new, larger mortgage on their own single income, without their former partner's income to support the application.
Option 2: Selling the Property
This is often the cleanest and simplest path from a financial perspective, although it can be emotionally difficult.
The Goal: The couple puts the home on the market and sells it.
The Benefit: From the proceeds of the sale, the existing mortgage is paid off in full, along with any other joint debts secured by the property (like a HELOC). The remaining profit is then split between the two spouses as laid out in their Separation Agreement. This provides a true "fresh start" for both parties, with no lingering financial ties to the property and often a significant cash payout to begin their new lives.
Option 3: One Spouse Assumes the Mortgage
In some cases, the spouse who is staying in the home can simply "assume" or take over the existing mortgage.
The Goal: Spouse A takes over the mortgage payments and legal responsibility for the loan.
The Nuance: This is less common than a refinance for a few key reasons. First, the mortgage must be legally "assumable." Second, and most importantly, Spouse A must still formally apply with the lender and prove they can qualify for the mortgage on their own income. Finally, this option doesn't provide any cash to pay out Spouse B's share of the equity. It's typically only viable when there is very little equity in the home or when the buyout is being paid from other assets.
The Spousal Buyout Program: A Broker's Solution
The biggest challenge for the person who wants to keep the home is almost always qualifying for the new, larger mortgage on a single income. This is where a mortgage broker can introduce a powerful and specialized solution: the Spousal Buyout Program.
Overcoming the Qualification Hurdle
Normally, to refinance a mortgage for more than 80% of the home's value, you would need to pay for mortgage default insurance. However, the Spousal Buyout Program is a special exception offered by many 'A' lenders (often accessible only through brokers) that is designed specifically for separating couples.
How the Program Works
This program allows the spouse keeping the home to refinance for up to 95% of the home's appraised value without it being considered a standard high-ratio insured mortgage. This provides access to a much larger loan amount than a traditional refinance, giving you the funds needed to pay your former spouse their share of the equity. The equity being paid out is essentially treated as the down payment.
A Real-World Example
Let's look at a common scenario. A home in Ontario is appraised at $1,000,000. The existing mortgage is $500,000, which means there is $500,000 in equity.
According to the Separation Agreement, Spouse A needs to pay Spouse B their 50% share, which is $250,000.
Through the Spousal Buyout Program, Spouse A can get a new mortgage for up to 95% of the home's value, which is $950,000.
This new mortgage is large enough to pay off the old $500,000 mortgage and pay out the $250,000 owed to Spouse B, leaving them with a new mortgage of $750,000. Without this program, Spouse A would have had to find another way to come up with the $250,000.
The Importance of Child & Spousal Support
A key element of making the buyout work is how lenders treat support payments. We can use court-ordered or agreement-defined child and spousal support payments received by our client as part of their qualifying income. For many single parents, this additional income is what makes them able to qualify for the new mortgage on their own.
A Broker's Role During The Separation
Navigating a mortgage during a separation is as much about having a calm and objective guide as it is about the numbers.
Working With Your Legal Team
Our role is to work in tandem with your family lawyer. We review the draft Separation Agreement to ensure the financial clauses are realistic and achievable from a lending perspective. This collaboration between your legal and financial experts is crucial for a smooth process.
Providing Clarity and Options
During a highly emotional time, it can be difficult to make objective financial decisions. We act as a neutral third party. Our job is to lay out all the possible scenarios—selling vs. buying out—and run the numbers for each. We can show you exactly what your new monthly payments would be and what your financial future would look like in each case, allowing you to make a logical decision, not just an emotional one.
Accessing the Right Lenders
Not all lenders offer flexible Spousal Buyout programs, and some are simply better and faster at processing these sensitive applications than others. As brokers, we know exactly which lenders to approach to secure the best possible terms for your specific situation.
Turning a Challenge into a New Beginning
Navigating a mortgage during a divorce is complex and stressful, but it's important to know that there are clear options and specialized programs designed to help. You do not have to feel like you are navigating this alone. The key is to build a strong professional team, including a trusted family lawyer to handle the legal agreement and an experienced mortgage broker to manage the financing strategy. With the right expert guidance, you can move forward with confidence and financial stability.
