Dying Without a Will in Ontario: What Intestacy Really Means for Your Family

Most people know they should have a will. Far fewer actually get around to making one. If you die without a valid will in Ontario, the law does not leave your estate in limbo — it follows a fixed set of rules that have nothing to do with your wishes, your relationships, or your family's actual needs. Understanding dying without a will in Ontario and the intestacy rules that apply is the first step toward making sure your estate ends up where you want it to go.

This article walks through what happens when Ontario's intestacy rules take over — who gets what, who gets nothing, what extra steps your family will face, and why a simple will remains the most important document most people never make.

What Does "Dying Intestate" Mean?

"Intestate" is the legal term for dying without a valid will. When that happens in Ontario, your estate is governed by the Succession Law Reform Act — a provincial statute that sets out a strict priority list for distributing everything you owned. The Act does not care about verbal promises, long-standing relationships, or what seems fair to the people you leave behind. It distributes your estate according to legal family status, full stop.

How Ontario's Intestacy Rules Distribute Your Estate

If You Leave a Surviving Married Spouse

Your legally married spouse receives the first priority. Under Ontario's intestacy rules, a surviving spouse is entitled to a preferential share of the estate before anything else is divided. As of writing, a specific dollar threshold applies to that preferential share — but those figures are set by regulation and can be updated, so verify the current amount at ServiceOntario or with an Ontario estates lawyer before relying on any number you find online.

After the preferential share is paid:

• If you have no children: your spouse receives the entire remainder of the estate.
• If you have one child: the remainder is split between your spouse and that child.
• If you have two or more children: the remainder is divided — your spouse receives a portion, and the balance is split equally among all your children.

Children who have already died but left their own children (your grandchildren) may step into their parent's share, depending on the circumstances.

If You Leave No Surviving Married Spouse

The estate passes to your children equally. If a child has predeceased you and left children of their own, those grandchildren generally divide their parent's share among themselves.

If You Leave No Spouse and No Children

The estate moves further up the priority ladder:

1. Parents — split equally between both parents if both survive, or entirely to the surviving parent.
2. Siblings — equally divided; a deceased sibling's children may take their parent's share.
3. Nephews and nieces, then more distant relatives, depending on who survives.
4. Escheat to the Crown — if no eligible relatives can be found, your estate passes to the Ontario government. It does not go to your friends, your favourite charity, your chosen community, or anyone else you might have wanted to benefit.

The Critical Gap: Common-Law Spouses Are Not Treated as Married Spouses

This is the point that surprises — and devastates — the most Ontario families.

Ontario's intestacy rules do not recognize common-law spouses. A spouse is defined, for intestacy purposes, as someone you are legally married to. It does not matter how long you have lived together, whether you share children, whether you jointly own a home, or how intertwined your financial lives are. If you are not legally married and you die without a will, your common-law partner has no automatic right to inherit anything from your estate under the Succession Law Reform Act.

Your common-law partner may be able to pursue a claim against the estate under other legislation — but those claims are uncertain, expensive, emotionally taxing, and far from guaranteed. A will drafted during your lifetime is a far simpler, more reliable, and far less costly way to protect a partner you have chosen to build your life with.

If you are in a common-law relationship in Ontario and you do not have a will, making one should move to the top of your list.

Intestacy Does Not Solve Guardianship

Ontario's intestacy rules govern the distribution of your property. They say nothing about who will raise your minor children.

If both parents die without naming a guardian in a will, the court will appoint one — based on the child's best interests, as determined by a judge who never knew your family. The people you would have chosen may or may not be the people a court selects. Naming a guardian in your will is the only reliable way to express your wishes on this question while you still can.

The Administrator Problem: No Will Means No Named Executor

When you die with a will, you name an executor — someone you trust to carry out your instructions. When you die without one, no executor exists. Instead, a family member (or other eligible person) must apply to the court for a Certificate of Appointment of Estate Trustee Without a Will — Ontario's formal term for what is sometimes called "letters of administration."

This process is slower and more expensive than the standard Certificate of Appointment of Estate Trustee (what many people call "probate"). The administrator must post a bond in many cases, is subject to strict court oversight, and can only act after the certificate is issued. Meanwhile, assets can sit frozen, bills can go unpaid, and families can experience real financial strain during an already difficult time.

A will with a named executor sidesteps most of this friction. Your executor can apply for the standard certificate and move forward much more quickly.

Costs and Delays: The Hidden Price of No Will

Intestacy does not save your estate money — it typically costs more:

• Court time and legal fees to obtain the Certificate of Appointment of Estate Trustee Without a Will.
• Bond premiums that an administrator may be required to pay.
• Family conflict when relatives disagree about who should administer the estate, sometimes leading to contested proceedings.
• Lost opportunities — assets that could have passed to a beneficiary directly (via a named designation or joint ownership) may instead flow through the estate and face delays.

Compare that to a straightforward will, which in many cases can be prepared for a flat, transparent fee. The math usually favors planning.
