Key takeaways
  • When people die at the same time, or it is uncertain who survived, each person's property is dealt with as if that person had survived the other.
  • Joint tenants or joint account holders in that situation are each deemed to hold as tenants in common, so the property is split rather than passing to a survivor.
  • Without a will, the Succession Law Reform Act sets the order of who inherits from each person: spouse, children, parents, siblings, nieces and nephews, then more distant kin.
  • Insurance proceeds in these cases are paid under the Insurance Act rules rather than by the estate rules alone.

Losing two family members in the same accident, fire or illness is devastating. When neither left a will, you may also face a hard legal question: if no one can say who died first, how does the law decide who inherits?

Ontario has a specific rule for deaths at the same time or in uncertain circumstances. This article explains that rule in plain language, how the intestacy order works for each person, and what to sort out first. It is general information, not advice on your family's facts.

The basic survival rule

The Succession Law Reform Act (SLRA) deals with this directly. When two or more people die at the same time, or in circumstances that make it uncertain who survived, the property of each person is disposed of as if he or she had survived the other or others.

In plain terms, each person's estate is worked out separately, as though that person had outlived the other. This prevents the law from guessing which spouse or relative died first, and it generally means one person does not inherit from the other in that situation. How it applies to a particular family depends on the facts, so a lawyer can confirm.

Joint property and accounts

Normally, jointly owned property passing by right of survivorship falls outside the estate. That cannot work if there is no clear survivor. The SLRA says that joint tenants, or joint account holders, who die in these circumstances are each deemed to hold as tenants in common.

This means each person's share is treated as part of that person's own estate rather than passing automatically to the other. Each share is then dealt with under that person's will or, if there is none, under the intestacy rules.

Who inherits from each person without a will

Once you treat each death separately, the normal intestacy order applies to each estate. The order depends on who is alive and who is related. The table summarizes the main steps.

Who survivesWho inherits
Spouse but no children or other issueThe spouse takes the whole intestate estate
Spouse and childrenThe spouse takes the preferential share first, then a fraction of the rest; the remainder goes to the issue
No spouse, but children or issueThe estate goes equally to the issue in the nearest degree, with a deceased child's share going to that child's own issue
No spouse or issueThe parents equally, or a sole surviving parent entirely
No spouse, issue or parentSurviving siblings equally, with a predeceased sibling's share going to that sibling's children
No spouse, issue, parent or siblingNieces and nephews equally, without representation; then next of kin of equal degree

If no one is entitled, the property becomes the property of the Crown and the Escheats Act, 2015 applies. Because the spouse usually cannot take from a spouse who is treated as having outlived them, the children or other relatives of each person often become the ones to look at. Your lawyer can walk through the exact result for your family.

Points that often change the answer

A common-law partner or other dependant may still be able to ask a court for support from an estate under Part V of the SLRA, even without an intestacy share. A support application generally must be made within six months after the grant of probate or administration, though a court may allow a late one for the part of the estate not yet distributed.

Insurance, pensions and RRSPs

Not everything passes under the estate rules. When deaths are simultaneous or uncertain, insurance proceeds are paid under sections 215 and 319 of the Insurance Act.

Retirement plans such as RRSPs, RRIFs and pensions can have a named beneficiary, designated by a signed instrument or by a will that expressly refers to the plan. The plan administrator is discharged by paying the person named in the latest valid designation, absent notice of a later one. If the named beneficiary also died, what happens depends on the plan terms, so check the paperwork and ask a lawyer.

What to do next

Frequently asked questions

Who is treated as dying first if no one knows?

The SLRA does not pick one. When deaths are at the same time or it is uncertain who survived, the property of each person is disposed of as if he or she had survived the other.

Does a surviving joint owner get the whole property in this situation?

If both joint owners die in such circumstances, they are each deemed to hold as tenants in common, so each share goes through that person's own estate.

Can a common-law partner inherit if neither left a will?

A common-law partner is not a spouse for intestacy purposes. They may still apply for dependants' support from the estate under Part V.

Is insurance paid out under the same rules?

Insurance proceeds in simultaneous or uncertain deaths are paid under sections 215 and 319 of the Insurance Act. The policy and any named beneficiary matter, so have the documents reviewed.
