What Happens If You Die Without a Last Will and Testament in Ontario?
If a person dies without a valid will in Ontario, they die intestate. That means their estate is not distributed based on personal wishes, verbal promises, or what surviving family members think is fair. Instead, Ontario law decides who inherits and in what order.
For many families, intestacy creates delay, added legal costs, uncertainty, and conflict. It can also produce outcomes the deceased would never have wanted.

- The preferential share in Ontario is currently $350,000 for deaths on or after March 1, 2021.
- Common-law spouses do not automatically inherit under Ontario intestacy law.
- If there is no will, someone must usually apply to be appointed as estate trustee without a will.
- Dying intestate often causes delay, expense, and avoidable family disputes.
What It Means to Die Intestate in Ontario
When a person dies without a valid will, Ontario’s Succession Law Reform Act determines who inherits the estate. This applies unless an asset passes outside the estate, such as through a designated beneficiary, joint ownership with right of survivorship, or certain trust arrangements.
In other words, intestacy rules generally apply only to assets that form part of the deceased’s estate.
Who Inherits If There Is No Will?
Ontario law sets out a strict order for inheritance. The outcome depends largely on whether the deceased left behind:
If no eligible relatives can be found, the estate may ultimately pass to the Crown.
If There Is a Married Spouse and No Children
If the deceased leaves a legally married spouse and no children, the spouse generally inherits the entire estate.
This is often the simplest intestacy scenario, but administration issues can still arise if no one has authority to deal with the estate until the court appoints an estate trustee.
If There Is a Married Spouse and Children
If the deceased leaves a married spouse and children, the spouse does not always receive the entire estate. Ontario law first gives the spouse the preferential share, and then the remainder is divided according to the number of children.
The Preferential Share
For deaths on or after March 1, 2021, the preferential share in Ontario is $350,000.
If There Is One Child
The spouse receives the first $350,000 of the estate. The balance of the estate is then divided equally between the spouse and the child.
If There Is More Than One Child
The spouse receives the first $350,000 of the estate. The residue is then divided so that:
- the spouse receives one-third of the residue; and
- the children share the remaining two-thirds equally.
Example
If an estate is worth $950,000 and the deceased leaves a married spouse and two children:
If There Are Children but No Spouse
If the deceased leaves children but no spouse entitled under the legislation, the children generally inherit the estate equally.
If a child died before the deceased but left descendants, those descendants may inherit their parent’s share by representation.
If There Is No Spouse and No Children
If there is no spouse and no descendants, Ontario law looks to the next class of relatives in order. Depending on the family structure, the estate may pass to:
What About Common-Law Spouses?
This is one of the most important issues in Ontario estate law. A common-law spouse does not automatically inherit under Ontario intestacy rules.
That often surprises people, especially those who lived together for many years, shared expenses, or considered themselves effectively married. While a common-law spouse may have other possible legal claims, including a dependant’s support claim in some cases, they do not receive the same automatic entitlement as a legally married spouse under the intestacy provisions.
What About Separated Spouses?
Separation can change intestacy rights. Ontario law now provides that a spouse who was separated from the deceased at the time of death may lose entitlement as a spouse for intestacy purposes if the statutory separation conditions are met.
This makes separation status a legally significant issue when determining who inherits if there is no will.
Who Administers the Estate If There Is No Will?
A will typically names an executor. If there is no will, there is no executor chosen by the deceased. Instead, someone usually must apply to the court to be appointed as estate trustee without a will.
The estate trustee is the person with legal authority to:
Until that appointment is made, practical administration can become difficult. Financial institutions and land registries often require formal legal authority before releasing assets or allowing transfers.
Practical Problems Caused by Dying Without a Will
Dying without a will can create serious practical and legal problems, including:
- delay because someone must seek court appointment to manage the estate;
- higher cost due to legal fees, court filings, and additional administrative steps;
- loss of control because Ontario law decides who inherits;
- family conflict over who should administer the estate or how assets should be handled;
- no tailored planning for vulnerable beneficiaries, blended families, disabled children, charities, or tax planning;
- no guardian appointment in a will for minor children, which can create further uncertainty.
For many families, the biggest mistake is assuming that “everything automatically goes to my partner” or “my family will sort it out.” In Ontario, that is not always how the law works.

Final Thoughts
Dying without a last will and testament in Ontario means the law decides who inherits your estate. That may or may not reflect your actual wishes. For married spouses, children, common-law partners, and blended families, the outcome can be very different from what people expect.
A properly prepared will is one of the most important estate planning documents a person can sign. It helps protect loved ones, reduce conflict, and ensure the right person has authority to administer the estate.
