Key takeaways
  • How the house is owned (joint tenancy or tenants in common) decides whether it passes by survivorship or becomes part of the estate.
  • A spouse with no children takes the whole estate; a spouse with children takes a $350,000 preferential share first for deaths on or after March 1, 2021.
  • A common-law partner does not inherit under Ontario's intestacy rules.
  • Probate is normally needed if the home does not pass by right of survivorship, and a certificate should be in hand before anyone signs an Agreement of Purchase and Sale.

When someone dies without a will, the family often assumes the house simply goes to whoever lived there or to the oldest child. In Ontario, it does not work that way. A set of legal rules decides who inherits, and a separate step decides who has the authority to deal with the home.

This article explains, in general terms, how the house is treated when there is no will, how a spouse's share works, who can apply to administer the estate, and what to sort out before anyone lists or sells the property. Every family's facts are different, so use it as a map, not a final answer.

First question: how was the house owned?

Before the intestacy rules even matter, look at the title. Ontario co-owners hold property either as joint tenants or as tenants in common. When a joint tenant dies, the surviving co-owners inherit the share. When a tenant in common dies, that share becomes part of their estate.

This means that if a couple owned the home as joint tenants, the survivor usually takes it outright, and the no-will rules never decide who gets it. If the deceased owned the home alone, or as a tenant in common, the share falls into the estate and the intestacy rules apply.

A copy of the deed or a title search will show how ownership is registered. If it is unclear, ask a lawyer to confirm before anyone assumes the answer.

How the intestacy rules divide the estate

If the house is part of the estate, it is divided with everything else the person owned, after debts and taxes. The rules depend mostly on whether there is a surviving spouse and whether there are children.

SituationWho takes what
Spouse, no childrenThe spouse takes the whole estate.
Spouse and children, net estate at or below the preferential shareThe spouse takes everything.
Spouse and one child, estate above the preferential shareThe spouse takes the preferential share, then one-half of what remains.
Spouse and two or more children, estate above the preferential shareThe spouse takes the preferential share, then one-third of what remains.

The preferential share is $350,000 for deaths on or after March 1, 2021. It was $200,000 before that.

In practice, the spouse takes the preferential share first, and how the rest is split depends on how many children there are, with the children sharing what is left.

The rules for situations with no surviving spouse, or involving more distant relatives, are not covered here. They depend on the family tree, and a lawyer can confirm who is entitled.

Common-law partners are treated differently

This surprises many families. Under Ontario's intestacy rules, a common-law spouse does not inherit. A partner who lived in the home for decades may have no automatic share of it under those rules.

That does not necessarily mean the partner has no other options. How this applies depends on the situation, so it is worth confirming with a lawyer. Get legal advice early if you are in this position.

Who can apply to administer the estate

Inheriting and administering are different things. The person who deals with the home, the bank accounts and the paperwork is the estate trustee. Their duties are to wind up the deceased's affairs, pay taxes and debts, collect assets and distribute the rest to those entitled.

With no will, the spouse or common-law partner usually has first right to apply to administer the estate. If there is none, a close adult relative can apply: a child, parent, grandchild, sibling, nephew or niece. The court may appoint the relative it considers most appropriate.

Note that the right to apply to administer is not the same as the right to inherit. A common-law partner may be first in line to apply even though they do not inherit under the intestacy rules.

If no eligible person can administer the estate, the Office of the Public Guardian and Trustee may apply to act, including where the deceased owned Ontario real estate. Where relatives disagree about who should act, that is a good time to speak with a lawyer.

Probate, tax and timing for the house

Probate is normally required if the deceased owned real property that does not pass to another person by right of survivorship. Estates valued at up to $150,000 can use a Small Estate Certificate, and larger estates use a Certificate of Appointment of Estate Trustee. An Estate Information Return must be filed within 180 calendar days after the certificate is received.

If the house must be sold, a certificate should be obtained before anyone signs an Agreement of Purchase and Sale. Listing or accepting an offer too early can cause problems with the buyer's lawyer.

The estate pays Estate Administration Tax. For certificates applied for on or after January 1, 2020, it is $0 per $1,000 on the first $50,000 and $15 per $1,000 on the rest. Ontario real estate counts at appraised date-of-death value, minus encumbrances such as mortgages or liens.

Income tax also matters. On death, the person is treated as having sold their property just before death, and any gain or loss goes on the final return. A home that qualifies as a principal residence must still be designated on the final return using Schedule 3 and Form T1255. A transfer to a surviving spouse or common-law partner who is resident in Canada may produce no gain or loss on the final return. The final return is due April 30 of the following year if death occurs January 1 to October 31, or six months after death if it occurs November 1 to December 31. An accountant can confirm how this applies.

What to do next

A lawyer can confirm who inherits on your family's facts, handle the application and explain the tax steps.

Frequently asked questions

Does the oldest child automatically get the house?

Not under the rules described here. If there is a surviving spouse and no children, the spouse takes the whole estate, and a spouse with children takes everything if the net value is not more than the preferential share. Otherwise the spouse takes the preferential share first, then one-half of the residue if there is one child or one-third if there are two or more children. How this applies to your family depends on the facts, so it is worth confirming with a lawyer.

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

Not under Ontario's intestacy rules, which do not give a common-law spouse a share. A common-law partner may still be first in line to apply to administer the estate. Other options may exist, so get legal advice.

Can the family sell the house before probate is granted?

Where probate is needed, a certificate should be obtained before anyone signs an Agreement of Purchase and Sale. Selling earlier can create problems at closing, so speak with a lawyer first.

What if nobody wants to or can administer the estate?

If no eligible person can administer the estate, the Office of the Public Guardian and Trustee may apply to act, including where the deceased owned Ontario real estate. Relatives who are eligible can usually apply themselves instead.
