Quick Answer
An Ontario resident with a $2,000,000 estate — primary home ($900,000), cottage ($450,000), RRSP ($350,000), and non-registered investments ($300,000) — who has two biological children and two step-children from a second marriage faces three intersecting challenges at death. First, the step-children have no automatic inheritance rights under Ontario's Succession Law Reform Act unless they are named in the will or qualify as dependants who were receiving support. Second, the cottage triggers a deemed disposition under section 70(5) of the Income Tax Act — if the original cost was $150,000, the $300,000 capital gain generates approximately $147,000 in taxable income on the terminal return. Third, Ontario probate fees (estate administration tax) on the full $2M estate are approximately $29,250. To avoid a dependant's relief claim from step-children who were receiving support, the will must either provide adequate support provisions or demonstrate that the step-children's needs are met through other means (life insurance, trusts, or inter vivos gifts). A testamentary trust for the step-children's share provides asset protection, staged distributions, and a documented rationale that makes a will challenge significantly harder to sustain.
Key Takeaways
- 1Step-children have no automatic inheritance rights in Ontario under intestacy rules — they only inherit if named in the will. However, step-children who were dependants receiving support from the deceased CAN bring a dependant's relief claim under Part V of the Succession Law Reform Act, potentially overriding the will's distribution.
- 2Ontario probate fees (estate administration tax) on a $2,000,000 estate are $29,250: $0 on the first $50,000, then $15 per $1,000 on the remaining $1,950,000. Probate applies to the gross value of assets that pass through the will — before taxes, debts, or mortgages.
- 3The cottage triggers deemed disposition at death under section 70(5). On a cottage purchased for $150,000 now worth $450,000, the $300,000 capital gain produces approximately $147,000 in taxable income — with the first $250,000 included at 50% and the remaining $50,000 at 66.67%.
- 4The primary residence exemption can only shelter ONE property. The family must designate which property — the home or the cottage — gets the principal residence exemption for each year of ownership. Whichever property is NOT designated is fully exposed to deemed disposition at death.
- 5A testamentary trust for step-children is significantly harder to challenge than an outright bequest. The trust provides documented rationale for the distribution amount, staged payouts tied to milestones, independent trustee oversight, and a clear record that the testator considered the step-children's needs — all factors that weaken a dependant's relief claim.
- 6The RRSP ($350,000) is the most tax-expensive asset to pass to any child. The full $350,000 is included as income on the terminal return — no capital gains inclusion rate, no exemptions. Combined with the cottage gain, the terminal return could show over $497,000 in taxable income, pushing into Ontario's top combined rate of 53.53%.
- 7Naming beneficiaries directly on the RRSP and using joint tenancy on the primary home can remove up to $1,250,000 from the probate calculation — reducing the $29,250 probate fee to approximately $10,500 on the remaining $700,000.
- 8An equal four-way split and a trust-for-step-children structure produce dramatically different outcomes in both tax efficiency and litigation risk. The trust approach costs approximately the same in total tax but provides far stronger protection against a will challenge.
Quick Summary
This article covers 8 key points about key takeaways, providing essential insights for informed decision-making.
The Estate: $2M Across Four Asset Classes
This worked example uses a realistic Ontario estate for a blended family. The deceased — a Mississauga resident in their mid-60s — is survived by a second spouse, two biological children from their first marriage (ages 28 and 25), and two step-children from the second marriage (ages 26 and 23). The step-children lived in the household during their teenage years and the deceased contributed to their post-secondary education expenses.
Estate Composition
| Asset | Fair Market Value | Adjusted Cost Base | Unrealized Gain |
|---|---|---|---|
| Primary home (Mississauga) | $900,000 | $400,000 | $500,000 |
| Cottage (Muskoka) | $450,000 | $150,000 | $300,000 |
| RRSP | $350,000 | N/A | 100% taxable |
| Non-registered investments | $300,000 | $200,000 | $100,000 |
| Total estate | $2,000,000 | — | — |
Each asset class has different tax treatment at death, different probate exposure, and different options for how it can be distributed. The challenge for the estate planner is structuring the will so that (a) the surviving spouse is protected, (b) all four children receive what the testator intends, (c) the tax bill is minimized, and (d) the distribution is defensible against a dependant's relief claim.
Step-Children and Ontario Inheritance Law: Who Has a Claim?
Under Ontario's intestacy rules, step-children have no automatic inheritance rights. If the deceased dies without a will, the estate is distributed to the surviving spouse and biological children only — step-children receive nothing. This is why a will is non-negotiable for blended families.
However, a will alone does not eliminate risk. Part V of Ontario's Succession Law Reform Act (SLRA) allows dependants to apply for adequate provision from the estate if the will does not provide sufficient support. A "dependant" includes any person to whom the deceased was providing support or was under a legal obligation to provide support immediately before death.
The Step-Child Dependant's Relief Risk
In this scenario, both step-children lived in the deceased's household during high school and the deceased paid for portions of their university tuition. The 23-year-old step-child is still completing a graduate degree. These facts create a credible dependant's relief claim — particularly for the younger step-child. A will that leaves nothing to the step-children, or provides a token amount, is vulnerable to a court application that could rewrite the distribution. The goal is to structure the will so that a dependant's relief claim either cannot be brought or cannot succeed.
How Each Asset Class Is Titled and Distributed
Primary Home ($900,000) — Joint Tenancy With Surviving Spouse
The Mississauga home is held in joint tenancy with right of survivorship. On the deceased's death, the home automatically passes to the surviving spouse outside the will — it does not go through probate, is not subject to Ontario probate fees, and cannot be redirected by a dependant's relief claim. The principal residence exemption is designated for the home for all years of ownership, sheltering the full $500,000 gain from tax. No deemed disposition tax on the home.
Cottage ($450,000) — Passes Through the Will
The Muskoka cottage is held solely in the deceased's name. It passes through the will, is subject to probate, and triggers a deemed disposition on the full $300,000 gain. Because the principal residence exemption is allocated to the home, the cottage receives no shelter. The will directs the cottage to the two biological children equally.
RRSP ($350,000) — Named Beneficiary: Surviving Spouse
The RRSP names the surviving spouse as beneficiary. Under the spousal rollover, the full $350,000 transfers directly to the spouse's own RRSP — no income tax on the terminal return, no probate. If the RRSP had no named beneficiary (or named the children), the entire $350,000 would be included as income on the terminal return at rates up to 53.53%. Naming the spouse saves approximately $170,000–$187,000 in immediate tax.
Non-Registered Investments ($300,000) — Passes Through the Will
The non-registered portfolio is held solely and passes through the will. It triggers deemed disposition on the $100,000 gain and is subject to probate. The will directs these assets to be split: a portion funds the step-children's testamentary trust, and the balance goes to the biological children.
Deemed Disposition on the Cottage: The $300,000 Capital Gain
The cottage triggers deemed disposition under section 70(5) of the Income Tax Act. The deceased is treated as having sold the cottage at $450,000 immediately before death. With an ACB of $150,000, the capital gain is $300,000.
Cottage Deemed Disposition Calculation
| Component | Amount |
|---|---|
| Cottage FMV at death | $450,000 |
| Adjusted cost base | $150,000 |
| Capital gain | $300,000 |
| First $250,000 at 50% inclusion | $125,000 taxable |
| Remaining $50,000 at 66.67% inclusion | $33,335 taxable |
| Total taxable capital gains from cottage | $158,335 |
The $158,335 in taxable capital gains is added to the non-registered portfolio gains and any other terminal-year income to calculate the total tax on the terminal return.
Why the Cottage — Not the Home — Gets Hit
The principal residence exemption can only shelter one property per year. The Mississauga home appreciated $500,000 ($25,000/year over 20 years). The cottage appreciated $300,000 ($20,000/year over 15 years). Designating the home as principal residence for all years shelters the larger total gain. The cottage's $300,000 gain is fully exposed. Splitting the designation between both properties might save tax in some scenarios — but in this case, the home's per-year gain ($25,000) exceeds the cottage's ($20,000), making full designation on the home the optimal strategy.
Ontario Probate Fees on a $2M Estate
Ontario's estate administration tax applies to the gross value of assets that pass through probate. The rate is $0 on the first $50,000 and $15 per $1,000 on everything above $50,000.
Probate Fee Scenarios: Full Estate vs. Structured Estate
| Scenario | Value Through Probate | Probate Fees |
|---|---|---|
| No planning — all $2M through probate | $2,000,000 | $29,250 |
| Home in joint tenancy + RRSP with named beneficiary | $750,000 | $10,500 |
| Savings from structuring | — | $18,750 |
Joint tenancy on the home removes $900,000 from probate. Naming the spouse as RRSP beneficiary removes $350,000. Only the cottage ($450,000) and non-registered investments ($300,000) pass through probate — reducing the fee from $29,250 to $10,500.
Side-by-Side: Equal Split vs. Trust-for-Step-Children
The core decision for the blended-family will is how to divide assets among the four children. Two common structures produce dramatically different outcomes in tax, litigation risk, and family dynamics.
Equal Split vs. Trust-for-Step-Children: Outcome Comparison
| Factor | Equal 4-Way Split | Trust for Step-Children |
|---|---|---|
| Surviving spouse receives | Home ($900,000) | Home ($900,000) + RRSP ($350,000) |
| RRSP treatment | Collapsed on terminal return — $350,000 taxable income | Spousal rollover — $0 immediate tax |
| Each biological child receives | ~$193,000 (after tax) | ~$307,000 (after tax) |
| Each step-child receives | ~$193,000 (outright) | $100,000 (via trust, staged) |
| Total tax on terminal return | ~$230,000 | ~$118,000 |
| Tax savings | — | ~$112,000 |
| Probate fees | $10,500 | $10,500 |
| Step-children's share funded by | Estate assets (reduces bio children's share) | Life insurance (does not reduce bio children's share) |
| Dependant's relief risk | Low — equal treatment | Low — documented, structured support |
| Asset protection for step-children | None — outright bequest | Full — trust protects from creditors and divorce |
The trust approach saves ~$112,000 in total tax by using the spousal RRSP rollover instead of collapsing the RRSP on the terminal return. The step-children receive less in total dollars but receive it in a protected, staged structure funded by life insurance.
Why the Trust Structure Saves $112,000 in Tax
The tax difference between the two scenarios comes almost entirely from one decision: what happens to the RRSP. In the equal-split scenario, the RRSP is collapsed on the terminal return because the surviving spouse does not need it — it is being divided among all four children. The full $350,000 is included as income at rates up to 53.53%.
In the trust scenario, the surviving spouse is named as the RRSP beneficiary. The spousal rollover under section 60(l) transfers the $350,000 directly to the spouse's RRSP — no immediate tax. The tax is deferred until the spouse withdraws from the RRSP or dies. This single structural change removes $350,000 from the terminal return and saves approximately $170,000 in immediate income tax. The difference is partially offset by the life insurance premiums paid during the deceased's lifetime to fund the step-children's trust — but the net savings are still substantial.
Structuring the Will to Prevent a Dependant's Relief Claim
The most dangerous scenario for a blended-family estate is a will challenge by step-children who were dependants. The following will-structuring strategies reduce this risk to near zero:
1. Include a Detailed Testamentary Trust for Step-Children
A testamentary trust with staged distributions (25% at 25, 25% at 30, remainder at 35) demonstrates that the testator gave serious, detailed consideration to the step-children's long-term needs. Courts evaluating dependant's relief claims look at whether the testator turned their mind to the dependant — a detailed trust is the strongest evidence of this.
2. Appoint an Independent Trustee
If the biological children are the trustees of the step-children's trust, the step-children will argue (correctly) that the people controlling their inheritance have a conflict of interest. An independent trustee — a trust company, a family friend, or a professional advisor — removes this argument entirely.
3. Fund the Step-Children's Share With Life Insurance
Life insurance proceeds paid to the testamentary trust are tax-free, bypass probate, and — critically — do not reduce the biological children's inheritance. This eliminates the zero-sum dynamic that drives most will challenges. The biological children have no reason to contest the step-children's share because it does not come from "their" assets.
4. Include a Memorandum of Wishes
A separate letter (not part of the will itself, but referenced by it) explaining the rationale for the distribution — why the step-children receive a trust instead of an outright share, why the amounts differ, and how the testator considered each child's needs — is powerful evidence in a dependant's relief hearing. The memorandum is not legally binding, but courts give significant weight to documented testamentary intent.
5. Continue Support Obligations Through the Trust
If the deceased was paying for the 23-year-old step-child's graduate school tuition ($15,000/year), the trust should explicitly continue this support until the degree is completed. Abruptly cutting off support at death is the single strongest trigger for a dependant's relief claim. A trust that continues existing support and adds a structured inheritance beyond it is nearly impossible to successfully challenge.
The Terminal Return: Pulling It All Together
Under the trust-for-step-children structure, the terminal return includes only the deemed disposition gains — the RRSP has been rolled to the spouse, and the home is sheltered by the principal residence exemption.
Terminal Return Summary (Trust Structure)
| Income Source | Amount | Taxable Amount |
|---|---|---|
| Pension + CPP + OAS (terminal year) | $40,000 | $40,000 |
| Cottage deemed disposition ($300K gain) | $300,000 gain | $158,335 |
| Non-registered deemed disposition ($100K gain) | $100,000 gain | $50,000 |
| RRSP | $350,000 | $0 (spousal rollover) |
| Primary home | $500,000 gain | $0 (PRE) |
| Total taxable income | — | $248,335 |
Estimated Tax on Terminal Return (Trust Structure)
| Component | Amount |
|---|---|
| Estimated federal tax | ~$42,000 |
| Estimated Ontario provincial tax | ~$18,000 |
| Ontario surtax | ~$3,000 |
| Total tax on terminal return | ~$63,000 |
Compare this to ~$230,000 under the equal-split scenario where the RRSP is collapsed on the terminal return. The spousal rollover on the RRSP alone saves approximately $167,000 in immediate tax.
What Each Family Member Actually Receives
Final Distribution Summary (Trust Structure)
| Recipient | Assets Received | Net Value |
|---|---|---|
| Surviving spouse | Home (joint tenancy) + RRSP (spousal rollover) | $1,250,000 |
| Biological child #1 | 50% of cottage + share of non-registered | ~$307,000 |
| Biological child #2 | 50% of cottage + share of non-registered | ~$307,000 |
| Step-child #1 | Testamentary trust (funded by life insurance) | $100,000 |
| Step-child #2 | Testamentary trust (funded by life insurance) | $100,000 |
| Total distributed | — | ~$2,064,000 |
The total exceeds $2M because the $200,000 in life insurance brings new money into the estate plan. Tax and probate consume approximately $73,500. Without the spousal RRSP rollover, tax and probate would consume approximately $240,500.
The 6-Month Window: Why the Estate Trustee Must Wait
Under Ontario law, a dependant's relief application must be brought within 6 months of the grant of probate. The estate trustee (executor) should not distribute any assets to beneficiaries until this 6-month window has passed — or until all potential dependant claimants have signed a release waiving their right to claim. Distributing the estate early and then facing a successful dependant's relief claim can make the estate trustee personally liable for the amount awarded.
Estate Trustee Personal Liability Risk
If the estate trustee distributes assets before the 6-month dependant's relief window closes, and a step-child subsequently brings a successful claim, the estate trustee may be personally liable for the amount the court awards — even if the distributed assets cannot be recovered from the beneficiaries. This risk is particularly acute in blended families where the step-children's dependant status may not be immediately obvious. The safe practice: hold all distributions until the 6-month window expires or all potential claimants have signed releases.
The Bottom Line
A $2,000,000 Ontario estate in a blended family is not a simple division problem — it is a three-dimensional optimization across tax, probate, and litigation risk. The trust-for-step-children approach saves approximately $112,000 in tax compared to an equal four-way split, protects the surviving spouse with $1,250,000 in tax-deferred assets, gives the biological children $307,000 each from the cottage and non-registered portfolio, and provides the step-children with $100,000 each in a structured, protected trust funded by life insurance.
The critical structural decisions are: (1) hold the home in joint tenancy to bypass probate and the will entirely, (2) name the surviving spouse as RRSP beneficiary to trigger the spousal rollover and avoid $170,000+ in immediate income tax, (3) designate the principal residence exemption for the home to shelter the $500,000 gain and accept the cottage's $300,000 deemed disposition, and (4) fund the step-children's testamentary trust with life insurance so their provision does not reduce the biological children's inheritance.
The dependant's relief risk is managed — not by paying off the step-children, but by documenting that the testator considered their needs, providing structured support through an independent trust, and continuing any existing support obligations. A will that demonstrates genuine consideration of each dependant's circumstances is far more defensible than a will that simply divides everything equally and hopes no one challenges it.
Frequently Asked Questions
Q:Can step-children challenge a will in Ontario?
A:Step-children can challenge a will in Ontario through a dependant's relief claim under Part V of the Succession Law Reform Act (SLRA). To qualify, the step-child must have been a dependant of the deceased — meaning the deceased was providing support or was under a legal obligation to provide support. If the step-child was a minor, a full-time student, or otherwise unable to support themselves AND the deceased was contributing to their support, they can apply to the court for adequate provision from the estate. The court considers the dependant's needs, the estate's size, the deceased's intentions, and any other relevant circumstances. A step-child who was financially independent and not receiving support from the deceased would have difficulty sustaining a dependant's relief claim. However, a step-child who lived in the household and received regular financial support — even informally — has a legitimate claim, and courts have awarded significant provisions in these cases.
Q:How much are Ontario probate fees on a $2M estate in 2026?
A:Ontario's estate administration tax (probate fees) for 2026 is calculated as: $0 on the first $50,000 of estate value, plus $15 per $1,000 on all value above $50,000. On a $2,000,000 estate: ($50,000 × $0) + ($1,950,000 × $15/$1,000) = $29,250. This is calculated on the gross value of assets that pass through probate — before deducting mortgages, debts, taxes, or funeral expenses. Assets that bypass probate (jointly held property with right of survivorship, registered accounts with named beneficiaries, life insurance with named beneficiaries) are excluded from the probate calculation. By structuring $1,250,000 of the $2M estate to bypass probate, the estate could reduce probate fees from $29,250 to approximately $10,500.
Q:How does deemed disposition work on a cottage at death in Ontario?
A:When the cottage owner dies, section 70(5) of the Income Tax Act deems the cottage to have been sold at fair market value immediately before death. The capital gain is the difference between the fair market value at death and the adjusted cost base (original purchase price plus eligible capital improvements). On a cottage purchased for $150,000 with $0 in capital improvements, now worth $450,000, the deemed disposition triggers a $300,000 capital gain. Under 2026 rules, the first $250,000 of gains is included at 50% ($125,000 taxable) and the remaining $50,000 at 66.67% ($33,335 taxable), producing $158,335 in taxable capital gains income. The principal residence exemption can shelter the cottage — but only if the family home is NOT designated as the principal residence for the same years. Most families designate the home (which typically has the larger gain) and leave the cottage fully exposed to deemed disposition.
Q:Should a blended family use a testamentary trust instead of an outright inheritance?
A:For blended families, a testamentary trust offers significant advantages over outright bequests — particularly for protecting against will challenges. A trust created in the will provides: (1) staged distributions tied to age or milestones rather than a lump sum at death, (2) an independent trustee who manages the funds and can document that the beneficiary's needs are being met, (3) creditor and family-law protection — the trust assets are not part of the beneficiary's net family property if they divorce, (4) a documented rationale in the will for why the trust structure was chosen, which courts consider when evaluating dependant's relief claims. A well-drafted testamentary trust demonstrates that the testator gave meaningful consideration to the step-children's needs — the single most important factor in defending against a dependant's relief claim. The trust does not need to provide an equal share to be defensible; it needs to provide adequate support relative to the dependant's needs and the estate's capacity.
Q:Can the principal residence exemption apply to both a home and a cottage?
A:No. A family unit can only designate one property as the principal residence for any given tax year. If you own both a home and a cottage, you must choose which property to designate for each year of ownership. The optimal strategy depends on which property has the larger per-year gain. For example, if the home appreciated $500,000 over 20 years ($25,000/year) and the cottage appreciated $300,000 over 15 years ($20,000/year), designating the home for all 20 years shelters the larger gain. The cottage's $300,000 gain is then fully exposed to deemed disposition at death. Some families designate the home for most years but switch the designation to the cottage for a few years to partially shelter the cottage gain. The calculation is property-specific and year-specific — a tax professional should model the optimal allocation before the terminal return is filed.
Q:What happens to an RRSP when you die with no surviving spouse in Ontario?
A:When an RRSP holder dies with no surviving spouse or common-law partner, the full fair market value of the RRSP is included as income on the deceased's terminal T1 return. Unlike capital gains, there is no partial inclusion rate — 100% of the RRSP value is taxable income. A $350,000 RRSP adds $350,000 to the terminal return, pushing the deceased deep into Ontario's top combined federal-provincial tax bracket of 53.53%. The tax on the RRSP alone is approximately $170,000–$187,000. If the RRSP names a financially dependent child or grandchild as beneficiary, the proceeds can be transferred to the child's own RRSP or used to purchase an annuity, deferring the tax. But for adult, financially independent children — the typical scenario in a blended family with grown step-children — there is no deferral: the estate pays the full tax on the terminal return, and the named beneficiary receives the RRSP proceeds directly (bypassing probate but not income tax).
Question: Can step-children challenge a will in Ontario?
Answer: Step-children can challenge a will in Ontario through a dependant's relief claim under Part V of the Succession Law Reform Act (SLRA). To qualify, the step-child must have been a dependant of the deceased — meaning the deceased was providing support or was under a legal obligation to provide support. If the step-child was a minor, a full-time student, or otherwise unable to support themselves AND the deceased was contributing to their support, they can apply to the court for adequate provision from the estate. The court considers the dependant's needs, the estate's size, the deceased's intentions, and any other relevant circumstances. A step-child who was financially independent and not receiving support from the deceased would have difficulty sustaining a dependant's relief claim. However, a step-child who lived in the household and received regular financial support — even informally — has a legitimate claim, and courts have awarded significant provisions in these cases.
Question: How much are Ontario probate fees on a $2M estate in 2026?
Answer: Ontario's estate administration tax (probate fees) for 2026 is calculated as: $0 on the first $50,000 of estate value, plus $15 per $1,000 on all value above $50,000. On a $2,000,000 estate: ($50,000 × $0) + ($1,950,000 × $15/$1,000) = $29,250. This is calculated on the gross value of assets that pass through probate — before deducting mortgages, debts, taxes, or funeral expenses. Assets that bypass probate (jointly held property with right of survivorship, registered accounts with named beneficiaries, life insurance with named beneficiaries) are excluded from the probate calculation. By structuring $1,250,000 of the $2M estate to bypass probate, the estate could reduce probate fees from $29,250 to approximately $10,500.
Question: How does deemed disposition work on a cottage at death in Ontario?
Answer: When the cottage owner dies, section 70(5) of the Income Tax Act deems the cottage to have been sold at fair market value immediately before death. The capital gain is the difference between the fair market value at death and the adjusted cost base (original purchase price plus eligible capital improvements). On a cottage purchased for $150,000 with $0 in capital improvements, now worth $450,000, the deemed disposition triggers a $300,000 capital gain. Under 2026 rules, the first $250,000 of gains is included at 50% ($125,000 taxable) and the remaining $50,000 at 66.67% ($33,335 taxable), producing $158,335 in taxable capital gains income. The principal residence exemption can shelter the cottage — but only if the family home is NOT designated as the principal residence for the same years. Most families designate the home (which typically has the larger gain) and leave the cottage fully exposed to deemed disposition.
Question: Should a blended family use a testamentary trust instead of an outright inheritance?
Answer: For blended families, a testamentary trust offers significant advantages over outright bequests — particularly for protecting against will challenges. A trust created in the will provides: (1) staged distributions tied to age or milestones rather than a lump sum at death, (2) an independent trustee who manages the funds and can document that the beneficiary's needs are being met, (3) creditor and family-law protection — the trust assets are not part of the beneficiary's net family property if they divorce, (4) a documented rationale in the will for why the trust structure was chosen, which courts consider when evaluating dependant's relief claims. A well-drafted testamentary trust demonstrates that the testator gave meaningful consideration to the step-children's needs — the single most important factor in defending against a dependant's relief claim. The trust does not need to provide an equal share to be defensible; it needs to provide adequate support relative to the dependant's needs and the estate's capacity.
Question: Can the principal residence exemption apply to both a home and a cottage?
Answer: No. A family unit can only designate one property as the principal residence for any given tax year. If you own both a home and a cottage, you must choose which property to designate for each year of ownership. The optimal strategy depends on which property has the larger per-year gain. For example, if the home appreciated $500,000 over 20 years ($25,000/year) and the cottage appreciated $300,000 over 15 years ($20,000/year), designating the home for all 20 years shelters the larger gain. The cottage's $300,000 gain is then fully exposed to deemed disposition at death. Some families designate the home for most years but switch the designation to the cottage for a few years to partially shelter the cottage gain. The calculation is property-specific and year-specific — a tax professional should model the optimal allocation before the terminal return is filed.
Question: What happens to an RRSP when you die with no surviving spouse in Ontario?
Answer: When an RRSP holder dies with no surviving spouse or common-law partner, the full fair market value of the RRSP is included as income on the deceased's terminal T1 return. Unlike capital gains, there is no partial inclusion rate — 100% of the RRSP value is taxable income. A $350,000 RRSP adds $350,000 to the terminal return, pushing the deceased deep into Ontario's top combined federal-provincial tax bracket of 53.53%. The tax on the RRSP alone is approximately $170,000–$187,000. If the RRSP names a financially dependent child or grandchild as beneficiary, the proceeds can be transferred to the child's own RRSP or used to purchase an annuity, deferring the tax. But for adult, financially independent children — the typical scenario in a blended family with grown step-children — there is no deferral: the estate pays the full tax on the terminal return, and the named beneficiary receives the RRSP proceeds directly (bypassing probate but not income tax).
