Key takeaways
  • A common-law spouse does not inherit under the Succession Law Reform Act on an intestacy.
  • Property held as joint tenants passes automatically to the surviving owner when one owner dies.
  • Joint ownership can be ended by severance during life, sometimes without the other partner agreeing.
  • The federal spousal tax rollover can apply to a common-law partner, but conditions and elections apply.

If you live with a partner but are not married, Ontario's default inheritance rules do not treat you like a spouse. Many couples hear that putting a home or bank account in joint names solves this. It can help, but only if the ownership is set up the right way and stays that way.

This article explains how joint ownership works for unmarried partners, where it can fall short, and what to check. It is general information, not advice for your own situation.

What the law does and does not give you

Ontario says a common-law spouse does not inherit under the Succession Law Reform Act when someone dies without a will. Its Family Law Act equalization and election rights are for married spouses, and common-law couples are not legally required to split property acquired while living together.

That is why ownership matters so much. Ontario explains that the assets in an estate are distributed depending on how they are owned, with money and property jointly owned with another person given as examples.

How joint ownership works as protection

If you own property as a joint tenant, it passes automatically to the surviving owner when you die. The right of survivorship applies only to interests held in a joint tenancy. Property that does not pass by survivorship goes to the deceased's personal representative.

How the asset is heldWhat generally happens on death
Joint tenantsThe interest passes to the surviving co-owners
Tenants in commonThe interest passes to the deceased's estate
Sole name, no will, unmarried partnerThe surviving common-law partner does not inherit under intestacy rules

Because survivorship property passes outside the estate, Estate Administration Tax excludes assets under joint ownership that automatically become the other owner's.

Ways joint protection can fall apart

The Court of Appeal for Ontario recognizes three ways to sever a joint tenancy: one owner dealing unilaterally with their own share, such as selling or encumbering it; a mutual agreement; or a course of dealing showing the interests were mutually treated as severed. A secret intention is not enough.

If you rely on survivorship, check the title and account records from time to time, especially after a relationship breakdown or a refinancing.

Paperwork, land transfer tax and income tax

For land, the survivor generally registers a survivorship application. In Land Titles it includes a statement that the applicant held the property as joint tenant with the deceased and is entitled as surviving joint tenant, with the date of death. For deaths on or after March 1, 1986, it must also include a Family Law Act statement, signed by a solicitor. Forms have changed recently, so a lawyer should confirm what is current.

Ontario's land transfer tax guidance says the Act excludes from disposition of a beneficial interest a transfer that happens by reason of the owner's death, which covers acquisition by operation of law such as a deceased joint tenant's interest.

For income tax, a person is treated as having disposed of capital property at fair market value immediately before death. Property passed to a surviving spouse or common-law partner resident in Canada may not produce a capital gain or loss on the final return, though the legal representative can elect out. The property must be locked in for the partner no later than 36 months after death, and an extension can be requested before the deadline. A home qualifies as a principal residence only if conditions are met, including that the deceased owned it alone or jointly, and it must be designated even if the gain is fully exempt.

What to do next

Frequently asked questions

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

Ontario says a common-law spouse does not inherit under the Succession Law Reform Act on an intestacy. Property you own jointly with survivorship passes outside the will and those rules.

Can my partner end the joint ownership without telling me?

A joint tenant can sever by registering a transfer to themselves, and the registrar then shows them as a tenant in common. A secret intention alone is not enough to sever by course of dealing.

Do I pay land transfer tax when I take over a home as survivor?

Ontario guidance says the Act excludes a transfer that occurs by reason of the owner's death, including acquisition by operation of law such as a deceased joint tenant's interest. A lawyer can confirm how it applies to your transfer.

Does the spousal tax rollover apply to unmarried partners?

The CRA says property passed to a surviving spouse or common-law partner resident in Canada may not result in a capital gain or loss on the final return. The legal representative can elect out, and timing rules apply.
