What Happens If You Die Without a Will in Ontario

If you die without a will in Ontario, you do not get to decide who inherits your estate. The province does, through a fixed formula set out in the Succession Law Reform Act. This is called dying intestate, and the outcome is often slower, more expensive, and less fair than the family expects. The law applies a standard division that cannot bend to your relationships, your blended family, your common-law partner, or your intention to treat one child differently from another.

This article is for Ontario residents who have been putting off a will and want to understand, plainly, what the alternative actually looks like. It explains who inherits under intestacy, how the process works, and the specific ways it can go wrong, so the case for a simple will is clear.

What intestacy means

Intestacy is the legal state of dying without a valid will. When it happens, three things follow. The distribution of your estate is governed entirely by statute. The court, rather than you, effectively decides who administers the estate. And several planning advantages that a will provides, naming a guardian for children, setting up trusts, minimising probate, are simply lost. None of this reflects neglect by the law; it is a default designed to be workable for the average case, which is precisely why it rarely fits a particular family.

Who inherits under Ontario’s rules

The division depends on who survives you.

• Spouse, no children. A married spouse inherits the entire estate.
• Spouse and children. The spouse first receives a preferential share, set at $350,000 for deaths in recent years, off the top. The remainder is then split: if there is one child, half to the spouse and half to the child; if more than one child, one-third to the spouse and two-thirds divided among the children.
• Children, no spouse. The estate is divided equally among the children, with a deceased child’s share passing to their own children.
• No spouse or children. The estate passes to parents, then siblings, then nieces and nephews, then more distant relatives, in a set order.
• No relatives at all. The estate ultimately passes to the Ontario government.

The single most important point for modern families is this: common-law partners do not inherit under intestacy, no matter how long the relationship. They may have to bring a dependant’s support claim, which is uncertain and adversarial. The word spouse in the intestacy rules means a married spouse only.

The table below summarises the common outcomes. Figures are set by regulation and can change, so confirm the current preferential share.

Who survives you	How the estate is divided
Married spouse only	Spouse receives everything
Spouse and one child	Spouse receives $350,000, then the rest split equally
Spouse and two or more children	Spouse receives $350,000, then one-third to spouse, two-thirds to children
Children, no spouse	Equal shares among children
Common-law partner	No automatic share; must make a legal claim
No spouse, children, or relatives	Estate passes to the Ontario government

Why intestacy costs more and takes longer

Beyond who inherits, the process itself is harder. Without a will there is no named executor, so someone, usually a family member, must apply to the court to be appointed estate administrator, which is the role covered in our note on executor duties in Ontario. The court often requires an administration bond, effectively an insurance policy guaranteeing the administrator’s conduct, which costs money and can be difficult to obtain. All of this adds months.

The estate still pays Ontario’s Estate Administration Tax, roughly 1.5% on value above $50,000, and a will does not avoid that on its own. But a will supports planning, beneficiary designations, trusts, sometimes multiple wills, that can reduce the exposed estate, as described in how to minimize probate fees in Ontario. Dying intestate forecloses all of it.

The problems intestacy creates for families

A few consequences recur and tend to surprise people.

• Minor children receive a lump sum at 18. Their share is generally paid into court and released in full the day they turn 18, with no trust, no staging, and no guardian of your choosing. Many parents would never leave a large sum to an 18-year-old without conditions.
• No guardian is named. The court decides who raises your minor children, without the benefit of your stated wishes.
• Blended families are poorly served. The rigid formula can leave a second spouse and children from a first marriage in direct conflict, a problem explored in estate planning for blended families.
• A disabled beneficiary can lose support. An outright inheritance can disqualify a beneficiary from provincial disability benefits, where a Henson trust in a will would have protected them.
• Business and cottage succession is left to chance. Assets that needed a plan are simply divided by formula, often forcing a sale.

What a will and a basic plan fix

Almost every problem above is solved by an ordinary estate plan: a valid will, powers of attorney for property and personal care, and current beneficiary designations on registered accounts and insurance. A will lets you name your executor, choose a guardian for your children, create trusts to manage inheritances, provide for a common-law partner, and direct specific assets to specific people. Our estate planning checklist for Ontario sets out the full list, and the broader work sits within our estate planning service.

The cost of a straightforward will is modest, usually a small fraction of what an intestate estate loses in bonds, legal fees, delay, and unintended distribution. For most families it is among the highest-value decisions in their financial life, precisely because the downside of skipping it is so concrete.

What happens between death and distribution

It helps to picture the practical sequence when there is no will, because the delay is where much of the cost hides. Someone must step forward to administer the estate, but they have no authority until the court grants it, which can take months. In the meantime, banks may freeze accounts, bills and taxes still fall due, and no one can legally deal with the assets. The administrator, once appointed, must inventory the estate, settle debts, file the deceased’s final tax return, and only then distribute what remains according to the statutory formula. Every step is slower without the clear authority and instructions a will provides, and the family often carries costs out of pocket until the estate is unlocked.

A partial will, or one that is out of date, can be nearly as troublesome as none. An old will that names a deceased executor, omits a later child, or no longer reflects a marriage or divorce can produce results the person never intended. In Ontario the rules on how marriage and divorce affect a will have changed in recent years, which is another reason to have a current document reviewed rather than relying on one drafted long ago.

A note on common-law couples

The position of common-law partners deserves emphasis because it surprises so many people. A couple can live together for decades, raise children, and own a home together, and still the surviving partner inherits nothing automatically under Ontario intestacy. Their only recourse is usually a dependant’s support claim or a claim based on their contribution to shared property, both of which are slow, uncertain, and often adversarial at the worst possible time. For common-law couples, a will is not merely advisable; it is the only reliable way to provide for each other, and it should be paired with joint ownership and beneficiary designations that support the same intention.

Next step

Dying without a will does not mean your estate goes unmanaged; it means it is managed by a formula that was never designed for your family.
