Key takeaways
  • Whether a common-law partner counts as a spouse depends on the statute, and the tests differ between insurance and pensions.
  • A pension spouse is entitled to the pre-retirement death benefit ahead of a designated beneficiary.
  • A dependant's support claim generally must be made within six months of the grant of letters probate or administration.

Losing a partner is hard enough without discovering that the law does not treat an unmarried partner the way it treats a spouse. In Ontario, the answer depends on which law and which asset you are asking about.

This article walks through where a common-law partner is counted as a spouse, where the answer needs checking, and the claims that may be available.

It depends on which law applies

There is no single definition. Each statute defines spouse for its own purposes, so a partner can qualify under one and not another.

AreaWho counts as a spouse
Insurance ActMarried people, people in a void or voidable marriage entered into in good faith, and unmarried people who live together in a conjugal relationship
Pension Benefits ActIncludes unmarried partners in a conjugal relationship who have lived together continuously for at least three years, or who are in a relationship of some permanence and are parents of a child
Tax (CRA rollover)Spouse or common-law partner

Because the tests differ, a partner of two years might qualify under one law and not another. The facts of the relationship matter.

Pensions, insurance and registered plans

If the partner was not named on the forms, that can limit what is available. A lawyer can explain the options on the specific plan.

Tax rollovers that may help

Capital property is generally treated as disposed of at fair market value just before death. For property passing to a surviving spouse or common-law partner, or to a qualifying testamentary spousal trust, there may be no capital gain or loss on the final return, provided the property vests in the spouse within 36 months of death.

For an RRSP, no amount is included on the deceased's return if the spouse or common-law partner is the sole designated beneficiary and all the property is transferred directly to a qualifying plan for them by December 31 of the year after the year of death. An accountant can confirm the current rules and deadlines.

The estate itself and support claims

If there was a will, its terms apply. If there was none, whether a common-law partner shares under the intestacy rules should be confirmed with a lawyer, because that depends on the statute and the facts. The rules giving a spouse a share also do not apply where spouses were separated at death, for separation events on or after January 1, 2022.

A surviving partner may also be able to claim as a dependant. For that claim, life insurance owned by the deceased and amounts payable under a plan designation are deemed part of the net estate. The application generally cannot be made more than six months after the grant of letters probate or administration, though the court may allow a later one against undistributed property.

What to do next

Frequently asked questions

Is a common-law partner a spouse for life insurance?

Under the Insurance Act, a spouse includes people who are not married but live together in a conjugal relationship. Common-law partners are therefore in the family class.

Can I get my partner's pension?

Possibly. An unmarried partner may qualify as a spouse under the Pension Benefits Act if they lived together continuously for at least three years, or are in a relationship of some permanence and are parents of a child.

Does a common-law partner automatically inherit if there is no will?

That should not be assumed. It depends on the statute and the facts, so ask a lawyer to confirm.

Can I make a claim against the estate?

You may be able to apply as a dependant for support. The application generally cannot be made more than six months after the grant of letters probate or administration.
