Key takeaways
  • Property that passes by true survivorship goes straight to the surviving owner and is left out of estate value for estate administration tax.
  • Adding an adult child to a parent's asset for no payment is presumed to be held in trust for the parent, so the tax saving may not hold.
  • Giving a child a share of property can trigger a capital gain right away, and joint assets can still be reached by a dependant's support claim.

Many people hear that putting a child or partner on title or on a bank account will keep the asset out of probate. Sometimes that is true. But it is not a simple shortcut, and the risks often surprise families later.

This article explains what right of survivorship does in Ontario, what actually escapes estate administration tax, and where adding a joint owner can backfire. It is general information, not advice on your situation.

What survivorship does

When an owner dies, property goes to the estate trustee only if no one else has a right to take it by survivorship. Property with a right of survivorship goes straight to the surviving owner, whether or not there is a will.

That also means a will cannot redirect it. A deceased joint tenant's interest goes to the surviving joint tenants, not to the will's beneficiaries.

Being on title together does not always create survivorship. Land given to two or more people is presumed to be held as tenants in common unless the document shows they are joint tenants. Spouses and common-law partners also hold as tenants in common unless the deed says otherwise.

What escapes estate administration tax, and what does not

For applications on or after January 1, 2020, there is no tax on an estate worth $50,000 or less, and above that the tax is $15 for every $1,000 (or part) of the estate's value. Value does not include jointly owned property that passes automatically to the other owner.

Probate is also not always needed. If a house is held in true joint tenancy and the surviving owner takes it, it can be dealt with without a Certificate of Appointment of Estate Trustee.

The resulting trust problem

The Supreme Court of Canada has said that for a transfer with no payment, the general rule is a presumption of resulting trust, and the person receiving it must show a gift was intended. An adult child added to a parent's account or asset is presumed to hold it in trust for the parent, and on death for the estate.

Only minor children benefit from the opposite presumption, a gift. An adult child's financial dependency does not trigger it, though it can be strong evidence against a resulting trust.

Courts may look at the bank documents, who controlled and used the funds, any power of attorney, the tax treatment of the account, and later evidence of the owner's intention at the time. If the asset is held in trust for the estate, it does not escape the tax.

Frequently asked questions

Does a joint account always go to the survivor?

Many joint accounts carry a right of survivorship, and the survivor becomes the owner. But heirs may challenge the survivor, who may have to show the deceased intended a gift.

Is a house owned with my spouse automatically joint?

No. Spouses and common-law partners are presumed to hold as tenants in common unless the deed says they are joint tenants.

Does survivorship avoid income tax at death?

No. The deceased is treated as having sold their capital property just before death, even when it passes by survivorship. A rollover may apply for a surviving spouse or common-law partner.

Can a dependant still claim against jointly held property?

Possibly. For a support claim, property held jointly at death and certain joint deposits can be counted in the net estate. Only the part of a joint deposit that belonged to the deceased is counted.
