Key Takeaways
- 1.Under Ontario's SLRA intestacy rules, the surviving spouse receives a $350,000 preferential share before any residue is split with children. On a $500K estate with two children, the spouse gets $400,000 total (80% of the estate).
- 2.RRSP, RRIF, TFSA, and life insurance proceeds with a named beneficiary bypass the estate entirely — they are not subject to intestacy rules, probate fees, or creditor claims against the estate.
- 3.A separated-but-not-divorced spouse retains full inheritance rights under the SLRA, including the $350,000 preferential share. Only a final divorce order terminates spousal entitlement.
- 4.In second marriages, children from all relationships share equally in the children's portion of the residue — the SLRA does not distinguish between children from current and prior marriages.
Ontario Intestacy Rules: How the SLRA Distributes an Estate
When an Ontario resident dies without a valid will — or when a surviving spouse elects against the will — the Succession Law Reform Act (SLRA) dictates exactly how the estate is divided. The formula depends on two variables: whether there are surviving children, and how many.
| Scenario | Spouse Receives |
|---|---|
| No children | 100% of the estate |
| One child | $350,000 preferential share + 50% of residue |
| Two or more children | $350,000 preferential share + one-third of residue |
The preferential share was increased from $200,000 to $350,000 in 2021 under Ontario Regulation 54/21. This threshold is not indexed to inflation and requires a regulatory amendment to change. The $350,000 goes to the spouse first, off the top, before any division with children begins.
Step-by-Step: Distributing a $500,000 Estate
Let's run through the calculation for our baseline scenario: a $500,000 estate, a surviving spouse, and two adult children. No will exists.
Step 1: Identify estate assets vs. non-estate assets
First, separate assets that pass through the estate from those that bypass it. This distinction is critical because the SLRA only governs estate assets.
| Asset | Value | Named Beneficiary? | Estate or Non-Estate? |
|---|---|---|---|
| Family home (joint tenancy with spouse) | $400,000 equity | N/A — right of survivorship | Non-estate |
| RRSP | $150,000 | Spouse named | Non-estate |
| TFSA | $85,000 | Spouse named | Non-estate |
| Life insurance | $200,000 | Spouse named | Non-estate |
| Non-registered investment account (sole name) | $300,000 | No | Estate |
| Savings account (sole name) | $80,000 | No | Estate |
| Vehicle | $35,000 | No | Estate |
| Personal property | $85,000 | No | Estate |
Total non-estate assets going directly to the spouse: $835,000 (home equity + RRSP + TFSA + life insurance). Total estate assets subject to SLRA distribution: $500,000 (investment account + savings + vehicle + personal property). The SLRA formula applies only to the $500,000 estate.
Step 2: Apply the preferential share
Preferential share = $350,000 → goes entirely to the surviving spouse
Step 3: Calculate the residue
Residue = $500,000 − $350,000 = $150,000
Step 4: Split the residue
With two children, the spouse receives one-third of the residue and the children share two-thirds equally:
| Recipient | Share of Residue | Amount |
|---|---|---|
| Surviving spouse | One-third | $50,000 |
| Child 1 | One-third (half of two-thirds) | $50,000 |
| Child 2 | One-third (half of two-thirds) | $50,000 |
Step 5: Total spousal inheritance
| Source | Amount to Spouse |
|---|---|
| Preferential share (from estate) | $350,000 |
| Spouse's share of residue (from estate) | $50,000 |
| Home equity (right of survivorship) | $400,000 |
| RRSP (named beneficiary) | $150,000 |
| TFSA (named beneficiary) | $85,000 |
| Life insurance (named beneficiary) | $200,000 |
| Total to surviving spouse | $1,235,000 |
| Total to each child | $50,000 |
The spouse receives $400,000 from the $500,000 estate (80%) and $835,000 from non-estate assets, for a total of $1,235,000. Each child receives $50,000. The non-estate assets dramatically shift the picture — without proper beneficiary designations, those RRSP, TFSA, and insurance proceeds would fall into the estate and change the calculation entirely.
Named Beneficiary vs. Estate Distribution: Why It Matters
The distinction between named-beneficiary assets and estate assets is the single most important variable in spousal inheritance planning. Here is what changes if the deceased had not named the spouse as RRSP and TFSA beneficiary:
| Scenario | Estate Value | Spouse from Estate | Each Child from Estate |
|---|---|---|---|
| RRSP + TFSA have named beneficiary (spouse) | $500,000 | $400,000 | $50,000 |
| RRSP + TFSA fall into estate (no beneficiary) | $735,000 | $478,333 | $128,333 |
When the RRSP ($150,000) and TFSA ($85,000) fall into the estate, the total estate grows to $735,000. The preferential share is still $350,000. The residue becomes $385,000, of which the spouse gets one-third ($128,333) and the children split two-thirds ($128,333 each). The spouse's estate share rises to $478,333 — but they lose the $235,000 that would have gone directly to them as named beneficiary. Net result: the spouse receives $78,333 more from the estate but $235,000 less overall. The children each gain $78,333.
Probate Fees Add Up
Ontario charges an Estate Administration Tax (probate fee) of 1.5% on estate assets above $50,000. On a $500,000 estate, the probate fee is approximately $7,250. On a $735,000 estate (with RRSP/TFSA falling in), the fee jumps to $10,775 — an extra $3,525 in fees that could have been avoided entirely by naming a beneficiary. Assets with named beneficiaries bypass probate completely.

What Happens with Only One Child?
The math shifts meaningfully with one child instead of two. With a single child, the spouse receives 50% of the residue instead of one-third:
| Component | Two Children | One Child |
|---|---|---|
| Preferential share to spouse | $350,000 | $350,000 |
| Residue | $150,000 | $150,000 |
| Spouse's share of residue | $50,000 (1/3) | $75,000 (1/2) |
| Each child's share of residue | $50,000 | $75,000 |
| Total to spouse from estate | $400,000 (80%) | $425,000 (85%) |
With one child, the spouse receives an additional $25,000 from the estate. The single child also receives more ($75,000 vs. $50,000) because they do not have to split the children's two-thirds share with siblings.
Estates Under $350,000: The Spouse Gets Everything
When the estate value is at or below the $350,000 preferential share threshold, the spouse receives the entire estate regardless of children. The preferential share operates as a floor — if there is not enough in the estate to satisfy it, the spouse takes what is available and the children receive nothing from the estate.
Estate = $280,000 → Spouse receives $280,000, children receive $0 from estate
This is why the 2021 increase from $200,000 to $350,000 was significant. An estate worth $300,000 under the old rules would have given the spouse $200,000 + one-third of $100,000 ($33,333) = $233,333, with $66,667 going to children. Under the current rules, the spouse receives the full $300,000.
Second Marriages and Blended Family Complications
Second marriages introduce the most contentious inheritance scenarios. The SLRA intestacy rules treat all children of the deceased equally — regardless of which marriage they are from. Consider this scenario:
| Detail | Value |
|---|---|
| Estate value | $500,000 |
| Surviving spouse (second marriage) | Current spouse of 5 years |
| Children from first marriage | 2 adult children |
| Children from second marriage | 1 minor child |
The distribution under SLRA intestacy:
| Recipient | Calculation | Amount |
|---|---|---|
| Current spouse | $350,000 + 1/3 of $150,000 | $400,000 |
| Child from first marriage (1) | 1/3 of 2/3 of $150,000 | $33,333 |
| Child from first marriage (2) | 1/3 of 2/3 of $150,000 | $33,333 |
| Child from second marriage | 1/3 of 2/3 of $150,000 | $33,333 |
The children from the first marriage each receive only $33,333 from a $500,000 estate. If the deceased intended for those children to inherit more — which is common when the second marriage is recent and most wealth was built during the first marriage — this outcome can feel deeply unfair. This is exactly why estate lawyers recommend a will for anyone entering a second marriage, especially when there are children from a prior relationship. Without a will, the SLRA's automatic formula overrides any informal understanding the family may have had.

Separated but Not Divorced: The Overlooked Risk
Ontario law draws a hard line between separation and divorce when it comes to inheritance. A married couple who has been separated for ten years, living in different cities with no contact — the surviving spouse still has full SLRA entitlement. The $350,000 preferential share. The one-third or one-half of residue. The right to elect against a will.
The only events that terminate spousal inheritance rights under the SLRA are:
- A final divorce order
- A valid domestic contract (separation agreement) that explicitly waives inheritance rights
- A court order under the Family Law Act that terminates spousal entitlement
Simple physical separation does none of these. This creates scenarios where a deceased person's current partner (common-law) receives nothing from the estate while the long-separated legal spouse inherits the preferential share. Common-law partners do not have inheritance rights under the SLRA regardless of the length of the relationship — only legally married spouses qualify.
Common-Law Partners and the SLRA
Unlike many provinces, Ontario does not extend SLRA intestacy rights to common-law partners. A common-law partner of 20 years has no automatic right to any share of the estate under the SLRA. They may have a claim under the doctrine of unjust enrichment or constructive trust, but that requires litigation. The only reliable way for a common-law partner to inherit is through a valid will or by being named as a beneficiary on registered accounts and insurance policies.
How RRSP Rollovers Work for Surviving Spouses
When a surviving spouse is the named beneficiary of an RRSP or RRIF, they have a unique tax advantage: the account balance can be rolled directly into the spouse's own RRSP or RRIF on a tax-deferred basis. No immediate tax is triggered. The tax is deferred until the surviving spouse eventually withdraws the funds.
Without a named spousal beneficiary, the full RRSP value is included in the deceased's final tax return as income, potentially triggering a massive tax bill. On a $150,000 RRSP, the combined federal and Ontario tax at the top marginal rate (53.53%) could reach $80,295. With a spousal rollover, that tax is deferred indefinitely.
| RRSP Scenario | Tax on Death | Net to Family |
|---|---|---|
| Spouse named as beneficiary (rollover) | $0 at death (deferred) | $150,000 to spouse's RRSP |
| No beneficiary (falls into estate) | Up to $80,295 | ~$69,705 to estate |
The TFSA equivalent is the successor holder designation. If the spouse is named as successor holder, they inherit the TFSA and it continues as their own TFSA without affecting their contribution room. If named as a beneficiary (not successor holder), the account closes and proceeds are paid to the spouse, but growth after the date of death may be taxable.

Adjusting the Calculator for Your Situation
The $500,000 estate with two children is our worked example, but the formula adapts to any estate size and family structure. Here are quick calculations for common variations:
| Estate Value | Children | Spouse Receives | Each Child Receives |
|---|---|---|---|
| $250,000 | 2 | $250,000 (100%) | $0 |
| $400,000 | 1 | $375,000 (94%) | $25,000 |
| $500,000 | 2 | $400,000 (80%) | $50,000 |
| $750,000 | 2 | $483,333 (64%) | $133,333 |
| $1,000,000 | 3 | $566,667 (57%) | $144,444 |
| $2,000,000 | 3 | $900,000 (45%) | $366,667 |
Notice the pattern: as estate value increases, the spouse's percentage decreases because the $350,000 preferential share becomes a smaller proportion of the total. On a $250,000 estate, the spouse gets 100%. On a $2,000,000 estate with three children, the spouse gets only 45%. This is why larger estates benefit most from proper will planning — the SLRA formula may not reflect the deceased's actual intentions.

Ontario Probate Fees on Estate Assets
Ontario's Estate Administration Tax applies to the total value of estate assets (not non-estate assets like named-beneficiary accounts). The rates are:
| Estate Value | Tax Rate |
|---|---|
| First $50,000 | 0.5% |
| Amount above $50,000 | 1.5% |
On a $500,000 estate: ($50,000 × 0.5%) + ($450,000 × 1.5%) = $250 + $6,750 = $7,000. This fee comes off the estate before distribution. Every dollar moved out of the estate through beneficiary designations, joint ownership, or inter vivos trusts reduces the probate fee.
