Roughly 58% of Canadians do not have a valid will. In Ontario, that means more than half the population has handed control of their estate to a set of provincial rules they have likely never read.
This guide covers:
• How Ontario’s intestacy laws divide your estate without your input
• Which family members are most at risk under the default rules
• What the probate process looks like when there is no will
• The practical consequences families face while waiting for court approval

How Ontario Law Divides Your Estate Without a Will
When someone dies without a valid will in Ontario, they are said to have died “intestate.” The province does not leave the distribution of that person’s estate to chance or to family consensus. Instead, the Succession Law Reform Act (SLRA) applies a fixed hierarchy of beneficiaries, regardless of the deceased’s actual relationships, intentions, or informal promises made during their lifetime. The formula is mathematical and uniform, and it does not bend to account for circumstances the deceased would have considered important. Research by IG Wealth Management found that roughly 58% of Canadians do; not have a valid will, which means the SLRA’s default rules are quietly governing the estate plans of millions of families who have never actually read them.
The distribution order under the SLRA works as follows. A surviving legally married spouse receives the first $350,000 of the estate outright (this is called the preferential share, and it was updated to this amount for deaths occurring on or after March 1, 2021). If the estate is worth less than $350,000, the spouse receives everything. If it is worth more, the remaining amount after the preferential share is divided between the spouse and any children: 50/50 if there is one child, or one-third to the spouse and two-thirds split equally among children if there are two or more.
If the deceased had no spouse but had children, the estate is divided equally among the children. If there are no spouse or children, the estate passes to parents, then to siblings, then to nieces and nephews, continuing down the family line in descending order of proximity. Should no eligible relatives be found at all, the estate escheats to the Ontario government.
| Family Situation | Who Inherits Under the SLRA |
| Married spouse, no children | Entire estate to spouse |
| Married spouse + 1 child | Spouse takes $350K preferential share; remainder split 50/50 |
| Married spouse + 2+ children | Spouse takes $350K; spouse gets 1/3 of residue, children share 2/3 |
| No spouse, children only | Estate split equally among children |
| No spouse, no children | Parents, then siblings, then nieces/nephews, then government |
Who the Intestacy Rules Leave Behind
The SLRA’s formula creates significant gaps for family structures that do not fit the traditional mould, and those gaps can have devastating financial consequences for the people left behind. The two most affected groups are common-law partners and blended families, and neither receives automatic protection under Ontario’s intestacy rules.
Common-law partners are the most exposed. No matter how long two people have lived together, shared finances, or raised children, a common-law partner has zero automatic right to inherit under the SLRA. The Act uses a narrow legal definition of “spouse” that requires a valid marriage. A surviving common-law partner who wants to claim a share of the estate must pursue a separate legal action, typically under the Family Law Act or through a dependant support claim. That process takes time, costs money, and is not guaranteed to succeed.
Blended families face a different but equally serious problem. Stepchildren are completely invisible under the SLRA. The Act recognizes only biological and legally adopted children. A person who raised a stepchild for two decades, considered them their own, and always intended to leave them an inheritance will have that intention overridden entirely by intestacy rules. The stepchild receives nothing, while assets flow to biological relatives the deceased may have been estranged from for years.
Firms such as Gill and Alter Law Firm regularly work with families navigating these gaps after an unexpected death, and the situations they encounter are rarely simple. Blended family disputes over intestate estates frequently require litigation to resolve, adding legal costs and emotional strain to an already difficult period.
What the Probate Process Looks Like Without a Will
When someone dies without a will, there is no named executor to step in and begin managing the estate. Someone must apply to the Ontario Superior Court of Justice to be appointed as the Estate Trustee Without a Will, and until that Certificate of Appointment is granted, no one has legal authority to access or distribute the deceased’s assets. According to the Ontario government’s estate administration guidance, if the deceased owned real property or assets held by a financial institution, the estate normally has to be probated before those assets can be distributed. This is where the practical consequences of dying intestate become most immediate for grieving families.
Bank accounts held solely in the deceased’s name are typically frozen from the moment of death until probate is resolved. Mortgage payments, utility bills, and other ongoing obligations do not pause. Families are often forced to bear those costs personally while waiting for court approval, which can take months, depending on the estate’s complexity and the local courthouse’s backlog. If multiple family members disagree about who should be appointed estate trustee, the matter may need to be referred to a judge, adding further delay.
The court may also require the applicant to post an administration bond, a form of financial insurance that protects creditors and beneficiaries against mismanagement. Bonding requirements add cost and complexity that would not arise if a clear will were in place. An experienced probate lawyer Mississauga families consult can guide the trustee through the application, help calculate the estate administration tax owed, and work to minimize unnecessary delays in getting the estate moving.
The Estate Administration Tax itself is calculated at 1.5% of the total value of the estate above $50,000. For an estate worth $800,000, that amounts to $11,250 due to the court before a probate certificate is issued. This cost applies whether or not a will exists, but having a will in place at least ensures the estate is administered efficiently by someone the deceased trusted.
The Specific Problem for Minor Children
Parents who die without a will leave a particular set of problems for their minor children that extend well beyond the question of who receives the money. Ontario law does not allow children under 18 to manage or receive an inheritance directly. When there is no testamentary trust established in a will, any funds to which minor children are entitled must be paid into court and held by the Office of the Children’s Lawyer until each child turns 18.
The practical consequences of this rule are significant. A surviving spouse who needs to access the deceased’s funds to cover household expenses, school fees, or medical costs for the children may find that a large portion of the estate is locked away and unavailable. The Office of the Children’s Lawyer will manage the funds conservatively and in accordance with its own mandate, not the family’s immediate needs.
The age-of-18 release date is itself a problem for many families. Receiving a potentially large lump sum at 18 with no conditions attached and no guidance from the parent is rarely what the deceased would have chosen. A properly drafted will allows a parent to establish a trust, name a trustee they choose, set conditions on when and how funds are distributed, and specify that the inheritance be held until a later age, such as 21 or 25. None of those options are available when someone dies intestate.
What Happens Next Is Not Out of Your Hands
Dying without a will does not have to be the outcome. Ontario law imposes the SLRA’s formula only in the absence of a valid will, and the cost of creating one is almost always far less than the legal and administrative costs the intestacy rules generate for the families left behind. The formula serves as a default, not a design.

Frequently Asked Questions
If the house was owned solely by the deceased, it forms part of the estate and is distributed under the SLRA’s intestacy rules. The estate trustee appointed by the court is responsible for managing the property, which may include selling it to satisfy debts or to distribute proceeds among beneficiaries. If the property is held in joint tenancy with a surviving co-owner, it passes directly to that person outside of the estate entirely.
No. Ontario’s Succession Law Reform Act does not recognize common-law partners as spouses for inheritance purposes, regardless of how long the couple lived together. A common-law partner who is not named in a valid will must pursue a separate legal claim, typically under the Family Law Act or as a dependant, to recover any share of the estate. These claims are not guaranteed to succeed.
The estate trustee appointed by the court is responsible for settling the deceased’s debts before distributing assets to beneficiaries. Debts are paid from the estate, not from the beneficiaries personally. If the estate’s debts exceed its assets, beneficiaries generally receive nothing, but they are not personally liable for the shortfall unless they co-signed the debt.
Settling an intestate estate typically takes longer than one with a valid will. The estate trustee application alone can take several months depending on court backlogs and whether family members dispute who should be appointed. Simple estates may conclude within six to twelve months; estates involving disputes or complex assets can take considerably longer.
The SLRA’s formula is fixed, but limited legal challenges are available. A financial dependant of the deceased may bring a support claim under the Family Law Act. A common-law partner may pursue a constructive trust claim if they contributed to property the deceased owned. Both routes require legal proceedings and must be initiated within prescribed limitation periods.
