When an Ontario resident passes away, their estate is administered under one of two legal regimes: testate (with a valid, legally executed Last Will and Testament) or intestate (without a valid will). Dying intestate does not mean the provincial government automatically confiscates your assets, unless you leave behind no surviving blood relatives at all—in which case the estate ultimately escheats to the Crown. However, dying without a will surrenders complete control of your estate to the rigid statutory formula in Part II of Ontario's Succession Law Reform Act (SLRA).
For families, real estate owners, and incorporated professionals across Markham and the Greater Toronto Area, the gap between what you assume your family will receive and what the Succession Law Reform Act actually mandates can result in frozen bank accounts, court-supervised minor shares, unintended disinheritance of common-law partners, and thousands of dollars in avoidable legal expenses.
1. What Enters the "Net Estate" vs. What Passes Outside the Will
Before applying Ontario's intestacy formula, an estate trustee must separate assets that pass outside the estate from assets that fall into the net estate:
- Registered Accounts & Insurance with Named Beneficiaries: RRSPs, RRIFs, TFSAs, and life insurance policies with a valid designated beneficiary generally pass directly to that named individual outside the estate and without probate.
- Joint Tenancy with Right of Survivorship: Real estate (such as a matrimonial home) and joint bank accounts held with a spouse as joint tenants typically pass automatically to the surviving joint owner by right of survivorship. (Caution: Under Supreme Court of Canada precedent, assets held jointly between an aging parent and a financially independent adult child are subject to a rebuttable presumption of a resulting trust, meaning they revert to the estate unless clear gift intent is proven).
- Solely Owned & Tenants-in-Common Assets (The Net Probate Estate): Individually held bank and investment accounts, real estate held solely or as tenants in common, personal property, and private corporation shares fall directly into the estate and are governed by your will—or, if you die intestate, by the SLRA formula.
2. The Ontario Intestacy Formula: How the $350,000 Preferential Share Works
Under section 45 of the Succession Law Reform Act and Ontario Regulation 54/95 (as amended by O. Reg. 122/21), a surviving legally married spouse is entitled to the first $350,000 of the net estate off the top—known as the preferential share—for deaths occurring on or after March 1, 2021 (up from the pre-2021 threshold of $200,000).
Once the $350,000 preferential share is satisfied, any remaining estate value (the residue) is divided strictly by statute between the married spouse and the deceased's children:
| Family Structure at Death | Statutory Distribution Under the Ontario SLRA | Practical Impact on Your Family |
|---|---|---|
| Married Spouse Only (No Children) | 100% of the net estate goes to the legally married spouse. | Clean transfer, though still requires a court application for Certificate of Appointment of Estate Trustee Without a Will. |
| Married Spouse + 1 Child | Spouse receives the first $350,000 (preferential share) + 50% of the residue. The child receives the remaining 50% of the residue. | On a $1,150,000 net estate, the spouse receives $750,000 and the child receives $400,000 outright (or paid into court if under 18). |
| Married Spouse + 2 or More Children | Spouse receives the first $350,000 + 1/3 of the residue. The children share the remaining 2/3 of the residue equally. | On a $1,250,000 net estate with 2 children, the spouse receives $650,000 ($350k + $300k), and each child receives $300,000. |
| Children Only (No Married Spouse) | 100% of the net estate is divided equally among all children (per stirpes if a child predeceased leaving grandchildren). | No surviving executor exists to manage or stage distributions past age 18. |
| Common-Law Partner (Unmarried) | $0 automatic entitlement under Part II of the SLRA. Estate passes to children, or if none, to parents/siblings. | Common-law partner must launch costly litigation via a Dependant's Support Claim (Part V of the SLRA) or unjust enrichment claim. |
| No Spouse, No Children / Descendants | 100% to surviving parents equally; if none, to siblings equally; if none, to nieces/nephews; then next of kin; otherwise escheats to the Crown. | Assets may pass to estranged relatives rather than chosen family or charities. |
3. Four Critical Traps of Dying Without a Will in Ontario
Trap 1: Minor Children's Inheritances Are Frozen & Paid Into Court
Many parents assume that if one spouse passes away without a will, the surviving parent automatically controls the entire estate for the benefit of their young children. That is false in Ontario. Under the SLRA formula, any share allocated to a child under the age of 18 does not go to the surviving parent. Without a will establishing a formal minor's trust and empowering a trustee, the children's shares must typically be paid into court under the oversight of the Office of the Children's Lawyer (OCL) and the Accountant of the Superior Court of Justice. The surviving parent must apply for approval to release funds for education or care, and the moment each child turns 18 years old, they are legally entitled to demand their entire inheritance in an unconditional lump sum. A properly drafted Will allows you to hold funds in a discretionary parent-controlled trust with staged distributions (for example, 25% at age 21, 35% at age 25, and 40% at age 30).
Trap 2: Common-Law Spouses Have Zero Automatic Intestate Rights
In Ontario, the definition of "spouse" for intestate succession under Part II of the SLRA is restricted strictly to legally married spouses. Even if you have lived with a common-law partner for 15 years and raised children together, your partner inherits nothing automatically if you die without a will. Instead, they are forced to hire litigation counsel and bring a Dependant's Relief application against your estate.
Trap 3: Separated Spouses Changes & Estate Equalization Exposure
Under recent reforms to Ontario's Succession Law Reform Act, a married spouse who was legally separated from the deceased at the time of death (meeting specific statutory separation criteria) is excluded from claiming an intestate share. Furthermore, a surviving married spouse always retains the right under section 5 of the Family Law Act to elect between receiving their entitlement under the Will/intestacy OR claiming an equalization of Net Family Property. Intentional estate planning coordinates your Will with domestic contracts and beneficiary designations to prevent litigation.
Trap 4: Delayed Administration, Bond Requirements & Higher Costs
When you name an Executor (Estate Trustee) in a Will, their legal authority flows from the Will itself the moment you pass away. When you die intestate, nobody has legal authority to deal with your estate until a family member petitions the Superior Court of Justice for a Certificate of Appointment of Estate Trustee Without a Will (formerly Letters of Administration). All adult beneficiaries must generally consent, and if there are minor beneficiaries or out-of-province administrators, the court may require an expensive Administration Bond (often double the value of the estate) unless waived by a judge.
4. Testate vs. Intestate: Executive Comparison Matrix
| Estate Planning Dimension | Testate (With an Ontario Lawyer-Drafted Will) | Intestate (No Will — Governed by SLRA) |
|---|---|---|
| Choice of Executor / Trustee | Chosen by you; immediate authority to secure assets. | Appointed by Superior Court; delays and potential family disputes. |
| Guardianship of Minor Children | Expressly appointed in your Will (90-day statutory appointment leading to permanent custody). | No guardian named; competing relatives must apply to court. |
| Control Over Minor's Inheritance | Held by your chosen Trustee with flexible education/maintenance access and staged payout ages (e.g., 25/30). | Supervised by the Court / Office of the Children's Lawyer; mandatory 100% lump-sum payout at age 18. |
| Common-Law Partner Protection | Fully customizable gifts, life interests in the home, and trusts. | Excluded from automatic inheritance; triggers litigation. |
| Private Company Probate Tax (1.5%) | Avoidable on private corporate shares using a Secondary Corporate Will. | Mandatory 1.5% Estate Administration Tax on all estate assets over $50,000. |
| Religious / Sharia Compliance | Fully customizable (e.g., Wasiyyah & Mawarith schedules). | Strict secular statutory split; violates Islamic inheritance obligations. |
Frequently Asked Questions
If I die without a will in Ontario and I am married with children, does my spouse get everything?
Only if your net probate estate is worth $350,000 or less. If your net estate exceeds $350,000, your legally married spouse receives the first $350,000 (the preferential share), and the remaining residue is split between your spouse and your children (50/50 if you have one child; 1/3 to your spouse and 2/3 split equally among your children if you have two or more children).
Do common-law partners automatically inherit in Ontario if there is no will?
No. Under Part II of Ontario's Succession Law Reform Act, only legally married spouses are entitled to an automatic intestate share. An unmarried common-law partner must file a court claim for dependant's support or constructive trust to receive provision from an intestate estate.
