Key takeaways
  • Married spouses in Ontario do not simply split every asset; the spouse with the smaller net family property is entitled to one-half of the difference between the two.
  • Debts count: what you owe on the valuation date is deducted from what you own, and the first possible valuation date is the day you separate with no reasonable prospect of living together again.
  • Common-law partners are not covered by the same equalization rules, so ownership and contributions matter more.

When a relationship ends, one of the first worries is what happens to the house, the savings, the cars and the debts. In Ontario the answer depends heavily on whether you were married or living together without marrying.

This article explains the basic approach for married spouses, what is left out of the calculation, how common-law couples are treated, and the steps people usually take next. It is general information, not advice on your situation.

The basic idea: equalization, not a pile-by-pile split

Ontario does not usually divide each item between spouses. Instead, each spouse works out the value of what they own less what they owe, and the two totals are compared. The spouse whose total is smaller is entitled to one-half of the difference between the two.

That payment is called an equalization payment. It evens out the growth in wealth that each spouse built up during the marriage, whoever's name was on the account or title. The detailed arithmetic is covered in our article on net family property.

The values are fixed as of the valuation date. The first of several possible dates is the day the spouses separate with no reasonable prospect that they will live together again.

Assets and debts both count

Your net family property is the value of the property you own on the valuation date, after deducting your debts and other liabilities. Credit cards, car loans and the remaining mortgage all reduce it.

Two dates matter. Property you owned at separation is valued as of the day you separated, and property you owned on your wedding day is valued as of the date of marriage. Debts you had at marriage are subtracted from the property you owned then, except debts tied to the family home, such as a mortgage.

What can change the result

Some property is not included in net family property. This covers property acquired during the marriage by gift or inheritance from a third person, personal-injury damages, and property the spouses agreed in a domestic contract to exclude. The exclusion does not apply to a matrimonial home.

That last point is important. The full value of the family home must be shared even if one spouse owned it before the marriage or received it as a gift or inheritance, unless the spouses agree otherwise.

A court may also award more or less than half the difference if equalizing would be unconscionable. One factor it considers is a spouse's intentional or reckless depletion of their net family property. Where needed to protect the other spouse's property interests, a court may make an interim or final preservation order restraining the depletion of property and providing for its possession, safekeeping and preservation.

If you are not married

Common-law couples are not legally required to split property acquired while living together, and items generally belong to whoever bought them. A partner who contributed to the other's property may need to go to court to recover that contribution.

The word spouse is used differently in different places. For property division, the Family Law Act's general definition covers only people who are married to each other or who entered a void or voidable marriage. For support claims, the definition also covers unmarried people who have cohabited continuously for at least three years, or who are in a relationship of some permanence and are the parents of a child. Because of this, the date your cohabitation ended can matter.

Deadlines and what to do next

An application for equalization cannot be brought after the earliest of three dates: two years after the marriage ends by divorce or judgment of nullity, six years after the spouses separate with no reasonable prospect of resuming cohabitation, or six months after the first spouse's death. A court may extend a Family Law Act time limit on a motion if there are apparent grounds for relief, the delay was in good faith, and no one will suffer substantial prejudice. Do not count on that, and act early.

Frequently asked questions

Do I get half of everything if we separate?

Not exactly. The spouse with the smaller net family property is entitled to one-half of the difference between the two net family properties. A court can award more or less than half the difference if equalizing would be unconscionable.

Does debt get divided too?

Debts are taken into account by deducting them from the property you own on the valuation date. How a debt is owed to the lender is a separate matter that depends on your credit agreement.

Is an inheritance shared?

Property acquired during the marriage by gift or inheritance from a third person is generally excluded from net family property, but this does not apply to a matrimonial home. The full value of the family home is shared even if inherited, unless the spouses agree otherwise.

How long do I have to claim?

The earliest of two years after divorce, six years after separation, or six months after the first spouse's death ends the right to bring an equalization application. A late claim may be possible only in limited circumstances.
