Key takeaways
  • Equalization compares each married spouse's net family property, and the spouse with the larger amount pays the other.
  • Some property is excluded, but the matrimonial home is treated differently and is shared even if one spouse owned it before the marriage.
  • Common-law partners are not covered by equalization, so their agreement has to settle property claims in other ways.

If you were married, the end of the relationship usually raises a money question: does one spouse owe the other an equalization payment? The answer comes from a formula set out in Ontario law, and your separation agreement is where the result is recorded.

This article explains the calculation in plain terms, what can be left out, and what to think about when you write it into the agreement. It is general information, and your own numbers and property can change the outcome.

How the equalization calculation works

Each spouse adds up the value of the property they own on the separation date and subtracts their debts and any excluded property. Then each spouse subtracts the value of the property, minus debts, that they owned on the date of marriage.

If the result is negative, it counts as zero. The spouse with the larger net family property pays the other spouse an equalization payment.

Pensions are part of the picture. Family Law Act s. 10.1 values a spouse's interest in a pension plan using the imputed value set under the Pension Benefits Act, and Ontario guidance says to ask the pension administrator for information about a pension's value.

What is excluded, and the matrimonial home

Excluded property includes property inherited or received as a gift from someone other than a spouse, personal injury damages, life insurance proceeds paid because someone died, and property excluded by a domestic contract.

The matrimonial home is an important exception. Spouses must share its full value even if one of them owned it before the marriage or received it as a gift or inheritance. It is divided equally unless the spouses agree to a different split.

Recording the payment in your agreement

Spouses can divide property any way they agree in a separation agreement. Ontario guidance says each spouse should have their own lawyer review it before signing, and that the agreement cannot easily be changed later.

A clear agreement usually sets out the following points:

For the agreement to be enforceable, it must be in writing, signed by the parties and witnessed.

Disclosure, time limits and common-law couples

Financial disclosure means giving the other party information and documents about your income, expenses, assets and debts. A court may set aside a domestic contract, or part of it, if a party failed to disclose significant assets or significant debts that existed when the contract was made. The Court of Appeal for Ontario has said disclosure is a paramount consideration, and that the spouse who holds the assets is responsible for disclosing and valuing them.

There is a time limit for an equalization claim: six years from the day of separation, or two years from the day the divorce is final, whichever comes first. A separate limb sets six months after the first spouse's death. The court keeps some discretion to extend time limits under the Act.

If you were not married, the equalization regime does not apply. Common-law couples are not legally required to split property acquired while living together, and household items belong to the person who bought them. A partner who contributed to property the other owns may have a right to part of it, and the separation agreement is where these claims are settled.

What to do next

Because it can be difficult to get a court to set aside a separation agreement, it is worth getting the numbers right before you sign.

Frequently asked questions

Who pays the equalization payment?

The spouse with the larger net family property pays the other spouse. If a spouse's calculation comes out negative, it counts as zero.

Is an inheritance included in equalization?

Property inherited from someone other than a spouse is generally excluded property. The exception is the matrimonial home, whose full value is shared even if it was inherited.

Do common-law partners get an equalization payment?

No. Ontario's equalization regime does not apply to unmarried couples. A partner who contributed to property the other owns may still have a claim, and the separation agreement is where it is settled.

How long do I have to claim equalization?

The time limit is six years from the day of separation, or two years from the day the divorce is final, whichever comes first. A separate limb sets six months after the first spouse's death. A lawyer can confirm how this applies to you.
