$5M Net-Worth Canada Estate Plan in 2026: Which Assets Go Into a Trust, Which Get the Spousal Rollover, and What the Deemed Disposition Still Hits

The $5M Estate: Asset-by-Asset Profile

This worked example uses a specific high-net-worth profile common among GTA business owners and professionals approaching retirement. The estate totals $5,000,000 across five asset classes, each with different tax treatment on death.

The estate plan must answer three questions for each asset: (1) does it qualify for an exemption that eliminates tax entirely, (2) can it roll over to the surviving spouse to defer tax, and (3) if neither applies, what is the deemed disposition tax bill at the 2026 inclusion rate?

Asset 1: The Principal Residence — $1.8M Toronto Home

The family home is the single largest asset in the estate and carries a $1,200,000 unrealized gain. Under the principal residence exemption (PRE), a property that was ordinarily inhabited by the taxpayer, their spouse, or their child can be designated as the principal residence for each year of ownership. The gain attributable to those years is fully exempt from capital gains tax.

The critical constraint: only one property per family unit can be designated as the principal residence for each calendar year. Since this estate also includes a Muskoka cottage, the principal residence designation must be allocated strategically between the two properties. In almost all cases, the property with the highest per-year capital gain should receive the designation — and for GTA families who purchased their home 20+ years ago, that is nearly always the city home.

Asset 2: The Cottage — $650K Muskoka Property

The cottage has a $450,000 unrealized capital gain. Since the Toronto home absorbs the principal residence designation, the cottage faces deemed disposition at fair market value on death. Without any planning, the executor must report a $450,000 capital gain on the final return.

The solution: transfer the cottage to a spousal trust under subsection 70(6). The cottage rolls over at the deceased's adjusted cost base ($200,000), deferring the entire $450,000 gain until the surviving spouse dies or the trust disposes of the property. This deferral can last decades — and if the surviving spouse makes the cottage their principal residence, it may eventually qualify for the PRE on their death.

Asset 3: CCPC Shares — $1.2M Operating Company

The Canadian-controlled private corporation shares represent the most complex asset in the estate. The $1,100,000 unrealized gain is the largest single capital gain, and the 2026 inclusion rate change hits it hardest.

For this estate, two strategies compete. If the CCPC shares qualify as QSBC shares and the deceased has unused LCGE room, the executor can claim the exemption on the final return — eliminating up to $1,250,000 in capital gains tax-free. If the shares do not qualify (common when the corporation holds substantial passive investments), the spousal rollover defers the entire gain to the surviving spouse's death.

The interaction between the LCGE and the spousal rollover is important: if you use the spousal rollover, you cannot also claim the LCGE on those shares. The rollover defers the gain at the deceased's ACB. When the surviving spouse eventually dies, their estate can then attempt to claim the LCGE — but the surviving spouse must have their own unused LCGE room and the shares must still qualify as QSBC shares at that time.

Asset 4: RRSP/RRIF — $600K in Registered Savings

Registered accounts follow different rules than capital property. The RRSP/RRIF balance is not a capital gain — it is fully included as income on the deceased's final return under subsection 146(8.8). At the top Ontario marginal rate of 53.53%, a $600,000 RRSP inclusion generates approximately $321,180 in tax.

If there is no surviving spouse, the $600,000 RRSP/RRIF balance is included as income on the final return. It can be transferred tax-deferred to a financially dependent child or grandchild under certain conditions, but for most high-net-worth estates with adult, financially independent children, the full tax applies. This is why the RRSP/RRIF beneficiary designation is one of the most important documents in any estate plan — more important, in tax terms, than the will itself.

Asset 5: Non-Registered Portfolio — $750K With $250K in Gains

The non-registered investment portfolio has a $250,000 unrealized capital gain. On death, this triggers a deemed disposition. At exactly $250,000, the entire gain falls within the lower 50% inclusion rate — but only if no other capital gains are reported on the same return.

The strategic choice: the non-registered portfolio can also roll to the spousal trust, deferring all tax. But if the surviving spouse does not need the assets for income, and the estate has sufficient liquidity from life insurance or other sources, it may be worth triggering the $250,000 gain at the lower 50% inclusion rate on the final return — especially if doing so preserves the $250K threshold for the surviving spouse's eventual deemed disposition. This is a decision that requires modelling both spouses' projected estates.

The 2026 Capital Gains Inclusion Rate: Impact at the $5M Tier

The 2026 capital gains inclusion rate change from 50% to 66.67% on gains above $250,000 has its greatest impact on high-net-worth estates like this one. Here is the comparison for the full $5M estate, assuming no spousal rollovers:

The $138,300 additional tax from the inclusion rate change is the strongest argument for proactive estate planning at the $5M tier. Every dollar of capital gains deferred through a spousal rollover is a dollar that does not get hit by the 66.67% rate on the first spouse's final return — and may benefit from the $250,000 lower-rate threshold on the second spouse's return.

The Testamentary Trust: Reducing Tax on Future Income

A testamentary trust created by will can be designated as a graduated rate estate (GRE) for up to 36 months after death. During this period, the estate is taxed at graduated marginal rates — the same brackets as an individual taxpayer — rather than the flat top rate.

For a $5M estate generating $100,000–$150,000 in annual income from the non-registered portfolio, CCPC dividends, and rental properties, the GRE can save $90,000–$120,000 in total over the 36-month period. After the GRE period expires, all income retained in the testamentary trust is taxed at the top rate. At that point, the trustee should distribute income to beneficiaries in lower tax brackets to minimize the overall family tax burden.

The Optimal Plan: Which Assets Go Where

Combining all five assets into a coherent estate plan produces the following allocation:

Life Insurance: Funding the Tax Bill Without Selling Assets

Even with the spousal rollover deferring tax on the first death, the surviving spouse's estate will eventually face the full deemed disposition. For a $5M estate, the deferred tax liability on the second death could exceed $500,000 — requiring the estate to sell the cottage, liquidate the CCPC, or draw heavily on the remaining portfolio to fund the tax bill.

A joint last-to-die life insurance policy (which pays out on the second death) can provide tax-free funds to cover this liability. Life insurance proceeds are received tax-free by the named beneficiary, bypass probate, and can be structured to pay directly into the testamentary trust. For a $5M estate, a $500,000–$750,000 policy provides a liquidity cushion that prevents forced asset sales at the worst possible time.

Ontario Probate Fees: The Hidden Cost

Ontario charges an estate administration tax (probate fee) of 1.5% on estate assets above $50,000. For a $5M estate, this is approximately $74,500 — payable before any distributions can be made. Assets that bypass probate (life insurance with a named beneficiary, RRSP/RRIF with a named beneficiary, jointly held property with right of survivorship) reduce the probate base.

The Bottom Line: $5M Estate Planning in 2026

A $5M Canadian estate in 2026 is not a single tax problem — it is five separate tax problems, each with different rules, different exemptions, and different planning tools. The principal residence exemption eliminates tax on the home. The spousal rollover defers tax on the cottage, CCPC shares, and non-registered portfolio. The RRSP/RRIF beneficiary designation handles registered accounts without a trust. And the testamentary trust reduces tax on future income during the 36-month GRE window.

The 2026 capital gains inclusion rate increase makes this planning more urgent than ever. The difference between a $5M estate with no planning ($800,000+ in tax) and a $5M estate with proper spousal rollovers, beneficiary designations, and trust structures ($67,000–$140,000 in tax on first death) is over $650,000. That gap is the cost of not having an estate plan — and at the $5M tier, it is a gap that no family should accept.

The most common mistake at this wealth level is assuming that the spousal rollover solves everything. It defers tax — it does not eliminate it. The surviving spouse's estate will eventually face the same deemed disposition, and the 21-year deemed disposition rule adds a ticking clock to any long-lived spousal trust. A complete estate plan at the $5M tier must address both deaths, fund the deferred tax liability (typically through life insurance), and use the GRE window to minimize tax on interim income.
