Spousal Beneficiary Inheritance Calculator: How Much of a $500K Estate Goes to a Surviving Spouse in Ontario

Published 2026-04-30 · 12 min read

Someone in Ontario dies with a $500,000 estate. They have a surviving spouse and two adult children. No will. How much does the spouse actually receive? The answer depends on Ontario's Succession Law Reform Act, the $350,000 preferential share rule, and whether key assets like RRSPs and TFSAs have named beneficiaries that bypass the estate entirely. This article walks through the math step by step.

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.

ScenarioSpouse Receives
No children100% 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.

AssetValueNamed Beneficiary?Estate or Non-Estate?
Family home (joint tenancy with spouse)$400,000 equityN/A — right of survivorshipNon-estate
RRSP$150,000Spouse namedNon-estate
TFSA$85,000Spouse namedNon-estate
Life insurance$200,000Spouse namedNon-estate
Non-registered investment account (sole name)$300,000NoEstate
Savings account (sole name)$80,000NoEstate
Vehicle$35,000NoEstate
Personal property$85,000NoEstate

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:

RecipientShare of ResidueAmount
Surviving spouseOne-third$50,000
Child 1One-third (half of two-thirds)$50,000
Child 2One-third (half of two-thirds)$50,000

Step 5: Total spousal inheritance

SourceAmount 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:

ScenarioEstate ValueSpouse from EstateEach 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:

ComponentTwo ChildrenOne 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:

DetailValue
Estate value$500,000
Surviving spouse (second marriage)Current spouse of 5 years
Children from first marriage2 adult children
Children from second marriage1 minor child

The distribution under SLRA intestacy:

RecipientCalculationAmount
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 marriage1/3 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 ScenarioTax on DeathNet 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 ValueChildrenSpouse ReceivesEach Child Receives
$250,0002$250,000 (100%)$0
$400,0001$375,000 (94%)$25,000
$500,0002$400,000 (80%)$50,000
$750,0002$483,333 (64%)$133,333
$1,000,0003$566,667 (57%)$144,444
$2,000,0003$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 ValueTax Rate
First $50,0000.5%
Amount above $50,0001.5%

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.

Frequently Asked Questions

What is the preferential share for a surviving spouse in Ontario?

Under Ontario's Succession Law Reform Act (SLRA), when a person dies intestate (without a valid will), the surviving spouse receives a preferential share of the estate before any residue is split with children. As of the 2021 amendment, the preferential share is $350,000. This means the spouse receives the first $350,000 of estate assets outright. If the estate is worth $350,000 or less, the spouse receives everything regardless of whether there are children.

How is the residue of the estate divided between a surviving spouse and children in Ontario?

After the surviving spouse receives the $350,000 preferential share, the remaining estate (the residue) is split between the spouse and children. If there is one child, the residue is split equally — 50% to the spouse and 50% to the child. If there are two or more children, the spouse receives one-third of the residue and the children share the remaining two-thirds equally among themselves. For a $500,000 estate with two children, the residue is $150,000 — the spouse gets $50,000 (one-third) and each child gets $50,000.

Do RRSP and TFSA accounts go through the estate or directly to the named beneficiary?

RRSP, RRIF, and TFSA accounts with a named beneficiary pass directly to that beneficiary outside of the estate. They do not go through probate, are not subject to the SLRA intestacy distribution rules, and are not available for the preferential share calculation. If a surviving spouse is named as the beneficiary on a $200,000 RRSP, they receive that $200,000 in full regardless of what happens with the estate. However, if no beneficiary is named on these accounts, they fall into the estate and are distributed according to the will or intestacy rules.

What happens if the deceased had a will that leaves everything to someone other than the spouse?

Even if a valid will exists that leaves the estate to someone else, the surviving spouse has a right to elect against the will under Part II of the SLRA. The spouse can choose to take their entitlement under the intestacy rules (including the $350,000 preferential share) instead of whatever the will provides, as long as they elect within six months of the grant of probate. This election right ensures a surviving spouse cannot be entirely disinherited. However, assets with named beneficiaries (RRSP, TFSA, life insurance) are not affected by the election.

Does separation affect a spouse's inheritance rights in Ontario?

In Ontario, legal separation alone does not terminate inheritance rights. A separated spouse who has not divorced retains their right to the preferential share and intestacy distribution under the SLRA. Only a final divorce order terminates spousal inheritance rights. This means a person who has been separated for years but never divorced could still inherit the full preferential share of $350,000 plus their share of the residue. This is a common oversight in estate planning and one reason why updating beneficiary designations and creating a will after separation is critical.

How does the spousal inheritance calculation change for a second marriage with children from a prior relationship?

The SLRA intestacy rules do not distinguish between children from the current marriage and children from prior relationships. All biological and legally adopted children of the deceased share equally in their portion of the residue. In a second marriage scenario, this means the current spouse receives the $350,000 preferential share plus their fraction of the residue, while children from both the current and prior marriages split the children's share equally. For a $500,000 estate with one child from the current marriage and one from a prior marriage, the spouse gets $350,000 + $50,000 (one-third of residue) = $400,000, and each child gets $50,000.
