What an Alter Ego Trust actually is.
A specialized inter-vivos trust available only to Canadians 65 and older — designed to move assets at cost, control succession, and avoid probate.
An Alter Ego Trust ("AET") is a category of inter-vivos trust defined in subsection 248(1) of the Income Tax Act. It is created by a Canadian-resident individual aged 65 or older, who is the only person entitled — during their lifetime — to receive income from the trust or to use or benefit from any of the trust's property. On death, the trust deed dictates who inherits, in what shares, and on what conditions, in much the same way a will would.
Two features make it structurally different from a normal trust. First, assets transfer in at adjusted cost base rather than fair market value, under subsection 73(1.01), so no capital gain is triggered on funding. Second, the standard 21-year deemed disposition that affects most Canadian trusts does not apply while the settlor is alive — the deemed disposition is deferred to the day the settlor dies.
Who qualifies — the 65+ test
Three conditions must be met for a trust to qualify as an Alter Ego Trust under the Income Tax Act:
| Requirement | What it means |
|---|---|
| Age | The settlor must be 65 or older at the time the trust is created. |
| Residency | The trust must be created and resident in Canada; the settlor must be a Canadian resident. |
| Sole beneficial use | While the settlor is alive, only the settlor can receive income or capital, and no other person can use or benefit from trust property. |
The third condition is the strictest. It is not enough that the settlor is the only named beneficiary on paper — no one else can have any present beneficial interest. A child living in a home held inside an AET, for example, would generally disqualify the structure unless they pay fair market rent.
How it works — funding & rollover
The settlor transfers assets — typically non-registered investments, private company shares, real property other than a principal residence, and certain other holdings — into the trust. Under subsection 73(1.01) the transfer occurs at the settlor's adjusted cost base, so no capital gain is realized at the time of funding. The trust inherits the settlor's ACB.
During the settlor's lifetime, the trustee (who can include the settlor) administers the assets according to the trust deed. Income earned in the trust is generally attributed back to the settlor under subsection 75(2), so the settlor pays tax on it personally as though the assets were still in their hands. There is no rate cost while the settlor is alive — the trust is tax-neutral on that dimension.
On the settlor's death, three things happen at once:
Deemed disposition at fair market value
Every capital asset in the trust is treated as having been disposed of at fair market value, under subsection 104(4). Accrued capital gains are realized — but inside the trust, not on the settlor's terminal return. The trust files a T3 return for the year of death.
Distribution per the trust deed
The remaining beneficiaries (children, grandchildren, charities, ongoing trusts) inherit according to the deed — bypassing the will entirely.
No probate on trust assets
Because the assets never form part of the estate, they do not attract probate fees in any province.
Probate avoidance — and quiet control
Probate fees vary widely by province. The two highest-fee jurisdictions and the typical AET savings are shown below:
| Province | Probate rate | Fee on $5M estate |
|---|---|---|
| Ontario | ~1.5% over $50K | ~$74,500 |
| British Columbia | ~1.4% over $50K | ~$69,500 |
| Alberta | Flat (max $525) | $525 |
| Quebec (notarial will) | Nominal | ~$0 |
Probate is a provincial fee on the gross value of estate assets passing under the will. AET assets pass outside the will and are not included in the calculation.
For an Ontario or BC family with a $5–25M estate, the probate saving alone can run from $70,000 to $375,000. In Alberta, the case is weaker — probate is effectively a non-issue, so AETs are used there mainly for control and privacy reasons rather than fees.
Control and privacy
A will is a public document once probated. A trust deed is not. Families who want the terms of distribution to remain private — common with blended families, second marriages, or large family businesses — use the AET to keep succession terms outside the public record.
Why HNW families use AETs. Probate avoidance is the headline. Privacy, control over conditional distributions (age gates, education trusts, addiction protections), and protection against will challenges are the durable reasons. A will can be contested in open court; an AET, properly settled years before death, is far harder to attack.
Tax treatment — during life and at death
While alive
Income is attributed to the settlor under subsection 75(2) and taxed on their personal return. There is no graduated-rate access (unlike a Graduated Rate Estate) and no separate trust-level tax bill while attribution applies. The trust files a T3 information return but tax is paid by the settlor.
At death
The trust experiences a deemed disposition of all capital property at fair market value. Capital gains are realized inside the trust, not on the settlor's terminal return, and are taxed at the top marginal rate (since AETs are taxed at the highest combined federal-provincial rate by default). One important consequence: capital losses realized inside the trust at death cannot be carried back to offset gains on the settlor's terminal return — a meaningful planning consideration if there are loss positions to harvest.
Principal residence
The principal residence exemption is generally not available on a home held inside an Alter Ego Trust. Practitioners almost always leave the principal residence outside the AET for this reason. See our PRE guide for the full mechanics.
Joint Partner Trusts — the spousal variant
A Joint Partner Trust ("JPT") is the equivalent structure for spouses or common-law partners. It works the same way as an AET, except that both spouses are entitled to income and capital during their lifetimes, and the deemed disposition is deferred until the second spouse's death rather than the first.
The JPT is often the better choice for couples because it pushes the deemed-disposition tax bill out by one full lifespan, much like the rollover available between spouses on death of the first under subsection 70(6). For many HNW Canadian couples in their late 60s and 70s, a JPT is the default unless a specific reason favours an AET (e.g., one spouse is non-resident, or only one spouse holds the assets at issue).
Where Alter Ego Trusts fail
Top-rate taxation on retained income
If the attribution rule does not apply for any reason, or after the settlor's death while the trust continues, income is taxed at the top combined marginal rate. There is no access to graduated rates that an estate (specifically a Graduated Rate Estate) enjoys for its first 36 months.
Loss of the principal residence exemption
A home held in an AET generally cannot claim the PRE. This is the single most common reason families fund an AET with everything except the home.
Loss carry-back limitations
Losses realized inside the trust at death cannot offset gains on the deceased's terminal return. If a portfolio holds significant unrealized losses alongside gains, this is a meaningful asymmetry compared to dying with the assets held personally.
Cost and complexity
Drafting fees typically run $5,000 – $15,000+, with annual T3 filings, accounting, and trustee coordination. The structure is rarely worth it on estates below roughly $2–3M in qualifying assets — probate savings simply don't justify the carrying cost.
Where it fits for HNW Canadians
For incorporated business owners and HNW families, AETs and JPTs typically appear in three patterns:
Probate-heavy provinces with $5M+ liquid wealth
Ontario and BC families with significant non-registered portfolios, holdcos with marketable shares, or recreational real estate use AETs/JPTs primarily for the probate saving. The fee differential alone covers drafting and ongoing trust costs many times over.
Blended families and conditional distributions
Where the desired distribution is unequal, conditional, or involves children from prior relationships, the privacy and control of a trust deed is materially stronger than a will. The AET sits alongside testamentary trusts created in the will.
Coordinated with corporate-side planning
AETs are typically just one piece of an estate plan that also includes an COLI policy funding the eventual tax bill, an estate freeze capping the value of the holdco at the freeze date, and personal life insurance to clear the AET's deemed-disposition liability. The AET handles probate and control; the insurance handles liquidity.
None of this is do-it-yourself. AETs are drafted by trust and estates counsel and coordinated with the family CPA. The strategic question — whether an AET or JPT actually fits — is what we help answer before any drafting begins.
FAQ
Yes. The settlor is commonly a trustee, often alongside a co-trustee (a spouse, a child, or a corporate trustee). Acting as trustee preserves the settlor's day-to-day control over investment decisions and distributions.
Typically non-registered investment portfolios, private company shares (often after an estate freeze), recreational real estate, and other capital assets that would otherwise pass through the will. RRSPs/RRIFs and TFSAs cannot be transferred into the trust without triggering tax. The principal residence is usually deliberately left outside the trust to preserve the PRE.
Some — but it is not bulletproof. A properly settled AET can offer modest creditor protection because the assets are held by a separate legal entity, but provincial fraudulent-conveyance statutes and the tax attribution rules limit how aggressive the protection can be. AETs are not asset-protection trusts; if creditor protection is the primary goal, other structures are usually better.
A regular family (discretionary) trust has multiple beneficiaries, faces the 21-year deemed disposition rule, and transfers assets in at fair market value (potentially triggering tax on funding). An AET is single-beneficiary during life, defers the deemed disposition until the settlor's death, and rolls assets in at adjusted cost base. They serve different planning goals.
Yes, and it is a common pattern after an estate freeze. The frozen "common" shares — which carry future growth — are held by a family trust, while the freeze "preferred" shares can be held inside an AET to bypass probate on the founder's death and provide a clean ownership transition.
There is no tax penalty for waiting, and drafting fees are the same. Most families create the AET when there is a triggering event — sale of a business, death of a spouse, retirement, or a probate-conscious estate review. Waiting too long is the more common mistake; capacity issues can complicate or invalidate a late-stage settlement.
