How is property divided when married spouses separate in Ontario?
In Ontario, ex-spouses do not split each family asset in half. Each spouse keeps what they own on the date of separation, and the spouse whose net worth grew more during the marriage pays the other half the difference. This is called an equalization payment, under Part I of the Family Law Act. The matrimonial home follows special rules.
Key points
-
Equalization shares the growth in net worth during the marriage, not the assets themselves.
-
Some property is excluded, including most gifts and inheritances from third parties.
-
If a home owned before marriage is the matrimonial home at separation, its whole value counts.
-
The claim for equalization must be brought within 6 years of separation or 2 years of divorce, whichever comes first.
-
These rules apply to married spouses only. Common-law partners have different rights.

How is the equalization payment calculated?
Each spouse calculates their net family property (NFP) in three steps:
-
Value everything you own, minus your debts, on the valuation date (usually the date of separation).
-
Value everything you owned, minus your debts, on the date of marriage. Do not count a home you owned then if it is the matrimonial home at separation.
-
Subtract step 2 from step 1, and remove any excluded property. That is your NFP. A negative NFP counts as zero.
The spouse with the higher NFP pays the other spouse half of the difference in their NFPs.
Worked example
Hypothetical figures.
Spouse 1 Spouse 2
Assets on separation date $600,000 $250,000
Debts on separation date -$50,000 -$10,000
Net worth on marriage date -$60,000 -$30,000
(not counting the matrimonial home)
Excluded property (inheritance or gift) $0 $0
Net family property $490,000 $210,000
The difference in NFPs is $280,000, so Spouse 1 owes Spouse 2 an equalization payment of $140,000. This can be paid in cash, by transferring property such as an RRSP or a share of the house, or over time if a court allows.
What property is excluded?
Some property a spouse holds on the valuation date is left out of their NFP calculation. The main exclusions are:
-
gifts and inheritances received from a third person after the marriage;
-
income received from a gift or inheritance, if the giver said in writing that it is excluded;
-
damages or settlements for personal injury;
-
life insurance proceeds;
-
property that can be traced to any of the above; and
-
property excluded by a valid marriage contract, cohabitation agreement, or other domestic contract.
The spouse claiming an exclusion must prove it. An inheritance or gift that was spent on family needs, for example, on downpayment for a matrimonial home, or mixed into other family accounts, can lose its excluded status. It must be traceable on the date of separation to be considered exclude property.
What happens to the matrimonial home?
A matrimonial home is any property a spouse has an interest in that the family ordinarily lived in at the date of separation. Married couple can have more than one matrimonial home at the same time, for example, a cottage can be one too. In terms of equalization, special rule apply: no marriage-date deduction. It means that if you owned the home before you got married and it is still the matrimonial home on the date of separation, you cannon deduct its pre-marriage value.
How are pensions and RRSPs divided?
RRSPs are valued like any other asset and can usually be rolled over to a spouse's RRSP without immediate tax when paid under an agreement or order. Workplace pensions are valued using a "family law value" and can often be transferred in part to the other spouse as a part of equalization. Canada Pension Plan credits earned during the relationship are shared equally if you lived together for at least one year.
Who is responsible for debts?
Each spouse is usually responsible for their own debts; both are liable for debts they both signed for. Debts on the valuation date reduce spouse’s NFP, which in effect shares them.
How long do I have to make a property claim?
In most cases, an equalization claim must be started by whichever comes first: 6 years after separation or 2 years after a divorce. When a spouse dies, the surviving spouse usually has 6 months to choose and claims either equalization of net family properties, or inheritance. A court can extend the deadline only in limited situations.
What financial disclosure is required?
Both spouses must give full and honest financial disclosure. In a court case, this means a sworn financial statement with supporting documents such as tax returns, account statements and appraisals must be prepared and served on the opposing party. Following the same process is strongly recommended in negotiated separations. Lack of meaningful disclosure may result in serious additional costs in a court proceeding.
Can property be divided unequally?
Not as a rule. A court can award more or less than half the difference only if an equal division would be unconscionable. It’s a high threshold and it requires serious evidence. Examples include a very short marriage, debts run up recklessly, or one spouse deliberately depleting their property.
From practice
Hypothetical example. Any resemblance to a real case is coincidental.
Nina owned a condo before she got married. The couple lived there for eight years, and it was their matrimonial home when they separated. Her husband had a larger RRSP, and Nina assumed her pre-marriage condo would be protected.
Because the condo was the matrimonial home at separation, she cannot deduct its marriage-date value. Its full value goes into her NFP. Had the couple sold it and bought a new home, the rule would likely have been different: the condo would no longer be the matrimonial home, and its marriage-date value could be deducted. Cases like this show why the history of each asset matters as much as its current value.
Frequently asked questions
Does my spouse get half the house if it is in my name? No. However, if the house was a matrimonial home on the date of separation, the house's value goes into equalization calculation, and your spouse may be entitled to half of its value.
Is my inheritance protected? Often, if you received it during the marriage and can trace it. It is not protected if it went into the matrimonial home or mixed with other family funds.
Do common-law partners get equalization? No. Unmarried partners keep what is in their own name, subject to certain trust claims.
What is the valuation date? Usually, the date you separated with no reasonable prospect of resuming cohabitation.
