Key takeaways
  • A surviving married spouse can claim equalization under the Family Law Act, take what the will gives, or take an intestacy share if there is no will.
  • The Election of Surviving Spouse form must be filed no later than six months from the death.
  • If you elect equalization, gifts to you in the will are generally treated as revoked unless the will says they are in addition.

When your spouse dies, the will may leave you less than you would receive if the family property were divided the way it would be on a separation. Ontario law gives a surviving married spouse a choice, and the choice has a firm time limit.

This article explains the options, the form and deadline, what happens if you do nothing, a separate claim for support, and some tax points to raise. Your situation may turn on details such as the size of the estate and how property was held, so a lawyer can confirm how this applies to you.

The choice you have as a surviving spouse

When a married spouse dies, the survivor can claim half the difference in net family property under the Family Law Act, take what the will gives, or, if there is no will, take their share under the Succession Law Reform Act.

These are alternatives. In general you cannot simply collect the best of both, which is why the effect of the election matters so much.

How an equalization claim is worked out

In the standard equalization calculation, each spouse values the property they owned on the separation date, less debts and excluded property, then subtracts the net property owned on the marriage date. The spouse with the larger net family property pays half the difference, and a negative share counts as zero. How the valuation applies when a spouse has died is worth confirming with a lawyer.

A court can divide the family home differently only in very special situations where an equal split would be extremely unfair. Comparing the equalization number with what the will leaves you is the heart of the decision. A lawyer or accountant can help value assets such as a business, a pension or a cottage.

The form and the six-month deadline

To claim equalization, the survivor must file the Election of Surviving Spouse form with the Estate Registrar for Ontario (c/o Toronto Estates Office, Superior Court of Justice) no later than six months from the spouse's death.

If no election is filed, the survivor is deemed to take under the will or the intestacy rules. Missing the date can therefore lock you into the will, even if equalization would have been worth more.

What the election does to the will

Check carefully whether the will says anything about gifts being in addition. That wording can change the result of the choice.

Tax points to raise with an accountant

At death, a person is deemed to have disposed of capital property at fair market value immediately before death. If capital property passes to a surviving spouse or common-law partner resident in Canada, or to a testamentary spousal trust, the deceased is instead deemed to sell at adjusted cost base, so the capital gain on the final return is zero and the survivor takes over the deceased's cost.

A surviving spouse or common-law partner can defer tax on a refund of premiums by transferring it to their own RRSP, PRPP, SPP, RRIF or eligible annuity, within the year received or within 60 days after the end of that year. To transfer into an RRSP, the survivor must be 71 or younger at the end of the year of transfer, and older survivors can use a RRIF or annuity instead. How this fits with your election depends on the facts, so confirm it with an accountant or lawyer.

Support claims and what to do next

Separately from the election, if the deceased did not make adequate provision for the proper support of dependants, a court may order adequate support out of the estate, with or without a will. A six-month limitation period applies to that claim. The point at which that period starts is something a lawyer should confirm.

Frequently asked questions

What if I miss the six-month deadline?

If no election is filed, you are deemed to take under the will or the intestacy rules. Whether anything can be done late depends on the facts, so speak with a lawyer quickly.

Can I take both the will gift and equalization?

Generally not. If you elect equalization, gifts to you in the will are deemed revoked unless the will expressly says they are in addition.

Does this apply to a common-law partner?

The equalization rules described here apply to married spouses. Common-law partners are not legally required to split property acquired while living together, but may recover contributions to the other's property.

Can the estate be paid out right away?

The estate cannot be distributed within six months of death without the survivor's written consent or court authorization.
