Property Division in Ontario

When married spouses separate, Ontario does not split each asset down the middle. Each spouse keeps what is in their own name, and the spouse whose net worth grew more during the marriage pays the other half of the difference. This is called equalization of net family property. Law Wise handles property division for clients from its Mississauga office, serving the entire GTA and Ontario.

How family property in Ontario is divided

Property division for married spouses is governed by Part I of the Family Law Act. The calculation follows five steps:

1. Valuation dateFix the valuation date. This is usually the day you separated with no reasonable prospect of resuming life together.
2. Property and debtsAdd up the value of everything each spouse owned on the valuation date, and subtract that spouse’s debts and other liabilities.
3. Date of marriageSubtract the net value of what that spouse owned on the date of marriage. A matrimonial home is left out of this deduction.
4. ExclusionsLeave out property that the Act excludes, such as certain gifts and inheritances.
5. EqualizationThe result is each spouse’s net family property. The spouse with the lower figure is entitled to one-half of the difference.

For example, if one spouse’s net family property is $400,000 and the other’s is $250,000, the difference is $150,000 and the equalization payment is $75,000. The figures are an illustration only.

The Act explains why: child care, household management and financial provision are the joint responsibilities of the spouses, and each is taken to contribute equally to them.

Excluded property

The value of the following property does not form part of a spouse’s net family property:

• a gift or inheritance received from a third person after the date of marriage, other than a matrimonial home
• income from that gift or inheritance, if the giver or the will expressly said it was to be excluded
• damages for personal injuries, or the part of a settlement that represents them
• proceeds of a life insurance policy that are payable on the death of the person insured
• property, other than a matrimonial home, into which any of the above can be traced
• property the spouses agreed to exclude in a domestic contract

The spouse who claims a deduction or an exclusion has to prove it, so records matter. An inheritance that was kept in a separate account is easier to trace than one that was mixed with family money, and an inheritance that was put into the matrimonial home loses its exclusion.

The matrimonial home

A matrimonial home is a property that the spouses ordinarily occupied as their family residence at the time of separation. A couple can have more than one, for example a house and a cottage. The matrimonial home is treated differently from every other asset:

• Its full value is shared. A spouse who owned the home on the date of marriage cannot deduct its value at that date, and a home received as a gift or inheritance is not excluded.
• Both spouses can live there. Both spouses have an equal right to possession of the matrimonial home, whoever is on title. Where only one spouse owns it, the other’s right ends when they stop being spouses, unless a separation agreement or court order says otherwise.
• It cannot be sold or mortgaged alone. A spouse cannot dispose of or encumber an interest in the matrimonial home unless the other spouse consents, has released those rights in a separation agreement, or a court order allows it.
• A court can order exclusive possession. A judge can give one spouse the sole right to live in the home for a period. The judge considers the best interests of the children, existing orders, the financial position of both spouses, any written agreement, whether other suitable and affordable housing is available, and any violence.

Pensions, businesses and other assets

A spouse’s interest in a pension plan is property and is valued under special rules. Businesses, investments, registered savings and real estate often need a professional valuation at the valuation date and, for property owned before the marriage, at the date of marriage. Debts count as well, including debts brought into the marriage.

When the division is not equal

A court can award more or less than half the difference only where equalizing would be unconscionable, having regard to factors listed in the Act. They include a spouse’s failure to disclose debts that existed at the date of marriage, debts incurred recklessly or in bad faith, intentional or reckless depletion of net family property, and an equalization payment that is disproportionately large for a period of living together of less than five years.

Protecting property while the case is decided

If there is a risk that property will be sold, transferred or run down before the claim is decided, a court can make an order restraining the depletion of a spouse’s property and an order for its preservation. Our page on court litigation and court orders explains how urgent orders are requested.

Common-law partners

The equalization rules apply only to married spouses. Unmarried partners each keep what is in their own name, and neither has an automatic right to share in an increase in the value of the other’s property. A partner who contributed to property owned by the other may still have a claim based on trust or unjust enrichment. These claims are decided by the courts on the evidence, case by case. A cohabitation agreement lets partners set their own rules in advance.

Marriage contracts and property

A marriage contract, often called a prenuptial agreement, can change how property is treated on separation, for example by excluding a business or a home owned before the marriage from net family property. It cannot limit the right to possession of the matrimonial home, and it can be set aside if it was made without proper financial disclosure or understanding. See separation agreements and domestic contracts.

Financial disclosure: what to gather

Property claims depend on documents. It helps to collect these early:

• bank, investment and registered account statements at the date of marriage and the date of separation
• mortgage statements and a recent appraisal or assessment for each property
• pension statements
• financial statements and tax returns for any business
• personal tax returns and notices of assessment
• loan, line of credit and credit card statements
• records of gifts and inheritances and where the money went
