Key takeaways
  • Part II of the Succession Law Reform Act sets out who inherits when someone dies without a valid will, and the order is fixed by statute.
  • A spouse with children takes a preferential share of $350,000 for deaths on or after March 1, 2021, before the rest is divided.
  • Common-law partners are not spouses under Part II, though they may have other routes such as a dependants' support claim.
  • If no one is entitled, the estate goes to the Crown.

People often say there is an Intestate Succession Act in Ontario. There is no statute with that name. The intestacy rules sit in Part II of the Succession Law Reform Act (SLRA), and they decide who inherits when a person dies without a valid will.

This article walks through what Part II actually provides, in the order the statute works through it. It is general information, not advice on a particular family. Real estates often raise facts that change the result, so it is worth confirming your situation with a lawyer.

What Part II covers and who counts as a spouse

"Intestate" simply means the person died without a valid will covering the property in question. Part II then sets the order of who takes. It works from the closest family outward: spouse and children first, then parents, siblings, nieces and nephews, and more distant relatives.

The word "spouse" matters a great deal. For Part II, a spouse is a married person, using the meaning in section 1 of the Family Law Act, so an unmarried common-law partner is not a spouse for intestacy. A common-law partner is not left with nothing in every respect, because Part V of the SLRA lets a common-law partner qualify as a dependant for a support claim.

Separation can also end a spouse's rights. Part II spousal entitlements do not apply if the spouses were separated at death, for example after living apart because of marriage breakdown for three years immediately before death, or where there was a valid separation agreement, a court order on the settlement of affairs, or a family arbitration award and they were living separate and apart at death. That rule applies only to events on or after the commencement of the 2021 amendment that created it, so the date of separation can matter.

When there is a spouse

If the deceased left a spouse but no children or other issue, the spouse takes the whole intestate estate. "Issue" means descendants such as children and grandchildren.

If there is a spouse and issue, the spouse first takes the "preferential share". If the net value of the intestate estate is no more than that amount, the spouse takes all of it. Net value is worked out after charges on the property, debts, funeral expenses and administration expenses. The preferential share is $350,000 for deaths on or after March 1, 2021, and was $200,000 for deaths before that date.

Where the estate is worth more, the spouse takes the preferential share and then a fraction of what is left. With one child, the spouse takes one-half of the residue. With more than one child, the spouse takes one-third of the residue, and the rest goes to the issue. If a child died first leaving issue alive at the death, the spouse's fraction is worked out as if that child were living.

When there is no spouse

With no spouse, the estate goes in the order below. A relative in an earlier row shuts out the later rows.

Who survivesWho takes
Children or other issueEqually to the issue in the nearest degree; the share of an issue who died first passes to that person's own issue
No issue, but parentsEqually to the parents, or wholly to a sole surviving parent
No issue or parent, but siblingsEqually to surviving brothers and sisters; a predeceased sibling's share goes equally to that sibling's children
No issue, parent or sibling, but nieces and nephewsEqually to nieces and nephews, without representation, so their own children do not take in their place
None of the aboveNext of kin of equal degree of consanguinity, equally and without representation
No one entitledThe property becomes the property of the Crown and the Escheats Act, 2015 applies

Degrees of kindred are counted up to the nearest common ancestor and then down to the relative, and relatives of the half-blood inherit equally with those of the whole blood in the same degree.

Special situations the statute addresses

On that last point, the election is filed with the Estate Registrar within six months after the first spouse's death, and if none is filed in time the survivor is deemed to have chosen the intestate entitlement unless a court orders otherwise. This is a deadline worth taking seriously and raising with a lawyer early.

What falls outside Part II, and what to do next

Part II divides only the property that forms the estate. Property that passes by right of survivorship, such as jointly owned property, is outside the estate. Plans such as RRSPs can pass by a beneficiary designation instead. So the rules above may apply to less than the whole of what a person owned.

Frequently asked questions

Is there an Intestate Succession Act in Ontario?

Not under that name. The intestacy rules are in Part II of the Succession Law Reform Act. Other statutes, such as the Family Law Act, also affect a surviving spouse.

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

Not under Part II, because a spouse there means a married person. A common-law partner can still qualify as a dependant and may bring a support claim under Part V. A lawyer can tell you how that applies to your facts.

How much does a spouse get if there are children?

For deaths on or after March 1, 2021, the spouse first takes the $350,000 preferential share. If more remains, the spouse takes one-half of the residue with one child, or one-third with more than one child.

What happens if there are no relatives at all?

If no one is entitled under Part II, the property becomes the property of the Crown and the Escheats Act, 2015 applies. Before that point, the statute works outward to nieces, nephews and more distant next of kin.
