What is a matrimonial home under Ontario’s Family Law Act?
A matrimonial home is any property that a married couple ordinarily occupied as their family residence at the time of separation. Under section 18 of Ontario’s Family Law Act, this designation carries significant legal weight — it affects how property is divided and whether a spouse can claim special protections. A property does not automatically become a matrimonial home just because a couple owns it or plans to live there someday.
In Sandhu v. Dhillon, 2026 ONSC 3371 (CanLII), the Ontario Superior Court of Justice worked through exactly these questions when two properties were in dispute — and the answers turned on some very specific facts.
Does a property have to be occupied at separation to be a matrimonial home?
Yes — ordinary occupation at the time of separation is a core requirement. The court confirmed that simply owning a property, or intending to live there in the future, is not enough to give it matrimonial home status. The couple must have actually been using the property as a family residence when they separated.
The court applied a flexible and contextual approach, drawing on established case law, and found that one of the disputed properties did not meet this threshold. Neither spouse had established ordinary or joint occupation of that property at the relevant time. A future intention to move in — no matter how sincere — cannot substitute for actual occupation.
Can a basement apartment be the sole matrimonial home?
Yes, it can. The court found that the basement apartment was the couple’s sole matrimonial home. This matters because Ontario law does not require a matrimonial home to be a large or impressive property — it just has to be where the family actually lived.
This outcome also had a direct financial consequence: because only one property qualified as the matrimonial home, the spouse who owned the other property before the marriage was entitled to claim a deduction for that pre-marital asset when calculating equalization of net family property. The date-of-marriage deduction was preserved.
Are admissions made during a trial binding in Ontario family law cases?
Generally, yes — a clear factual concession made during trial proceedings will bind the party who made it. In this case, one spouse had conceded during the trial that a particular property was not the matrimonial home. The court treated this as a binding factual admission.
Attempts to walk back that concession were rejected. The court distinguished cases from criminal law where admissions are sometimes treated differently, and found no basis to disturb the admission in this civil family law context. Once a party makes a clear factual concession in court, they cannot simply change their position afterward because the outcome is unfavourable.
Can new information be added after a trial through supplementary written submissions?
No — supplementary submissions cannot be used to introduce new facts that were never part of the trial record. The court was firm on this point: its analysis was confined strictly to the evidence actually presented at trial.
Any new assertions that appeared in post-trial written submissions were disregarded entirely. This is an important reminder that the evidentiary record closes at trial. If information is not put before the court during the hearing itself, it generally cannot be relied upon later to change the outcome.
Why does matrimonial home status matter so much in property division?
Matrimonial home status affects several important rights. Both spouses have an equal right to possession of a matrimonial home, regardless of who holds title. A spouse cannot sell or mortgage a matrimonial home without the other spouse’s consent. And in equalization calculations, the rules around deductions for pre-marital value differ depending on whether a property qualifies.
If a property is wrongly characterized as a matrimonial home — or wrongly excluded — the financial consequences can be substantial. Getting this classification right is one of the most consequential steps in any Ontario separation involving real estate.
Practical takeaways for separating spouses
- Occupation at separation is what counts. Owning a property or planning to live there is not enough — actual use as a family residence at the time of separation determines matrimonial home status.
- Watch what you concede at trial. Factual admissions made during court proceedings are binding. Before agreeing to any characterization of a property, understand the financial implications.
- Pre-marital assets can still be protected. If a property does not qualify as a matrimonial home, you may be entitled to deduct its value at the date of marriage from your equalization calculation — but you need to document this carefully.
- Post-trial submissions are not a second chance to add evidence. If there is information you want the court to consider, it must be introduced during the trial itself.
- Get legal advice early. The difference between one matrimonial home and two can mean tens or hundreds of thousands of dollars in an equalization payment.

FAQ
Frequently asked questions
Under section 18 of the Family Law Act, a matrimonial home is a property that a married couple ordinarily occupied as their family residence at the time of separation. Ownership alone is not enough — actual use as a family home at the relevant time is required.
Yes, Ontario law allows for more than one matrimonial home if the couple ordinarily occupied multiple properties as family residences at separation. However, each property must meet the ordinary occupation test — vacation properties or investment properties that were not regularly used as a family home typically will not qualify.
If a property you owned before marriage does not qualify as a matrimonial home, you are generally entitled to deduct its value at the date of marriage when calculating your net family property for equalization purposes. This deduction can significantly reduce the equalization payment you owe.
