Trusts in Canada — A Plain-English Introduction

A 67-year-old Winnipeg widow has a disabled adult son who lives with her, plus a younger daughter who is a working professional. She wants to leave half her estate to each child. If she leaves the son's half outright in the will, he will lose the provincial disability benefits the family has spent twenty years navigating. If she leaves the daughter to "look after him," she has just created a recipe for sibling conflict and zero legal protection. A discretionary trust in her will — sometimes called a Henson trust — solves the problem in a way the will alone cannot.

That tension between "what the will can do" and "what the family actually needs" is the most common reason a Canadian household ends up looking at trusts. Most people don't need them. The ones who do, need them badly enough that the cost and complexity earn their place. This article explains what a trust actually is in Canadian law, the kinds that show up in normal estate plans, and the tax rules that quietly shape every decision.

The three-cornered relationship #

Every Canadian trust has the same three roles:

• The settlor — the person who transfers property into the trust. For a testamentary trust, the settlor is the testator of the will; for an inter vivos trust, it is whoever signs the trust deed and contributes the initial property.
• The trustee — the person (or trust company) who legally owns and manages the trust property, with a fiduciary duty to act in the beneficiary's interest. The trustee is governed by the relevant provincial Trustee Act.^[5]
• The beneficiary — the person (or class of people) entitled to benefit from the trust property. Beneficiaries can be present-interest holders (income beneficiaries) or future-interest holders (capital beneficiaries), and the same person can be both.

The trust deed (or the will, for a testamentary trust) sets out the rules: who the trustees are, who the beneficiaries are, what discretion the trustees have, when distributions can or must happen, and when the trust ends.

Inter vivos versus testamentary #

The first cut in Canadian trust planning is when the trust comes into existence.

Inter vivos trusts are created during the settlor's lifetime. A trust deed is signed, property is transferred in, and the trust is up and running while the settlor is still alive. Family trusts, alter-ego trusts, joint-spousal trusts, and discretionary trusts for a disabled adult child set up while the parent is alive are all inter vivos trusts. They are generally taxed at the highest federal personal rate on retained income from day one.

Testamentary trusts come into existence at death, on the words of the will. The most common version is the residue of the estate held in trust for minor children until they reach a stated age, but the same mechanism is used for second-marriage planning, spendthrift beneficiaries, and Henson trusts for disabled beneficiaries. Since the 2014 federal budget reforms, most testamentary trusts no longer enjoy the favourable graduated rate they once did.^[2]

The 21-year deemed-disposition rule #

The single most important tax rule shaping Canadian trust planning is the 21-year rule under subsection 104(4) of the Income Tax Act.^[1] On the 21st anniversary of a trust's creation, the trust is generally deemed to have sold all of its capital property at fair-market value and reacquired it at the same value — even though no real sale has occurred. The accrued capital gain is taxed inside the trust at the top federal rate.

For long-running family trusts, the 21-year date is a planning milestone the trustees and accountants generally track from the beginning. The standard moves are some combination of distributing capital out to beneficiaries before the deadline (so the gain rolls out on a tax-deferred basis), winding the trust up entirely, or — where the structure permits — rolling assets into a new vehicle. Anti-avoidance rules attack obvious workarounds, including indirect trust-to-trust transfers.

Graduated Rate Estate (GRE) and Qualified Disability Trust (QDT) #

Two important exceptions survived the 2014 reforms.

The Graduated Rate Estate (GRE). An estate that arose on the death of an individual can be designated as a GRE if it elects on its first T3 return and meets certain conditions. It receives graduated personal tax rates and an off-calendar fiscal year for up to 36 months after the date of death.^[2] After 36 months, the estate generally moves to a calendar year-end and the top federal rate. The GRE window is a real planning advantage and one of the standard reasons estate accountants push for clean, prompt T3 filings.

The Qualified Disability Trust (QDT). A testamentary trust set up for a beneficiary who qualifies for the federal Disability Tax Credit can elect QDT status annually and continue to receive graduated personal rates indefinitely — not just for 36 months. Only one QDT per beneficiary per year. The QDT is the modern tax-efficient companion to a Henson-style disability trust.

Henson trusts — the disability-benefits problem #

A Henson trust is typically an absolute discretionary trust under which the disabled beneficiary cannot compel distributions or unilaterally control the trust property. Whether the beneficiary's interest is counted as an asset for eligibility purposes depends on the wording and structure of the particular benefits program. See S.A. v. Metro Vancouver Housing Corp., 2019 SCC 4, [2019] 1 S.C.R. 99.^[4]

That last sentence is the part most summaries drop. S.A. established a nationally binding method of analysis, not a blanket national exemption — it concerned a contractual rental-assistance program, and the answer turned on that program's wording. Most common-law provinces accept the structure for ODSP-style asset-limit purposes, but "accepted" is program by program, and the drafting has to be matched to the regime the beneficiary actually relies on.

Historical footnote. The structure is commonly associated with Director of Income Maintenance Branch of the Ministry of Community and Social Services v. Henson (1987), 26 O.A.C. 332 (Div. Ct.), aff'd (1989), 36 E.T.R. 192 (C.A.). The father, Leonard Henson, had left assets in trust for his daughter Audrey, who relied on provincial disability benefits, with the trustees given absolute discretion over whether to make any payment to her at all. In Henson, the Ontario courts held that a beneficiary's interest in an absolutely discretionary trust was not an asset for the applicable benefit-eligibility analysis because the beneficiary had no enforceable right to compel distributions and no unilateral control over the trust property. The Supreme Court of Canada subsequently considered the treatment of such trusts in S.A. v. Metro Vancouver Housing Corp., 2019 SCC 4, [2019] 1 S.C.R. 99.

Alter-ego and joint-spousal trusts #

For Canadians 65 and older, two inter vivos vehicles are specifically allowed by the Income Tax Act to roll capital property in without triggering tax. An alter-ego trust is for a single settlor, age 65+, who remains the sole lifetime beneficiary. A joint-spousal trust has both spouses (or common-law partners) as lifetime beneficiaries, with the same age threshold for at least one of them.

The point of both vehicles is to take title to assets — most commonly real estate, non-registered investment portfolios, or business interests — outside the estate while the settlor is alive. On death, the assets pass to the named successor beneficiaries without passing through the estate or through probate. The tax bill that would otherwise hit the final return is generally deferred until the death of the surviving lifetime beneficiary.

These structures are powerful, but they come with real costs: legal setup, ongoing T3 trust returns, and the 21-year clock starting from the trust's creation. Unlike most other family trusts, alter-ego and joint-spousal trusts generally remain on the short list of trusts still permitted to claim the principal-residence exemption on a home held inside them — but confirm eligibility with an accountant rather than assuming it.

When a trust earns its place — and when it doesn't #

Trusts are tools. They are worth their cost when:

• A beneficiary cannot manage money for legitimate reasons (age, disability, addiction, financial vulnerability)
• A beneficiary's benefits or means-tested supports must be protected
• The estate is large enough that probate-avoidance savings outweigh setup costs
• A blended family needs a structured way to support the surviving spouse for life while preserving the residue for the testator's biological children
• A business or family cottage needs to stay intact across generations rather than being forced into a sale

They are usually not worth it when:

• The estate is modest and the beneficiaries are competent adults
• All major assets already pass by valid beneficiary designation or joint ownership
• The complexity will simply create work for an executor without a corresponding advantage

The trust conversation belongs with a lawyer and an accountant for almost every Canadian household where it is realistically on the table. The cost of getting the structure wrong — losing disability benefits, triggering the 21-year tax bill earlier than expected, or running afoul of attribution rules — is generally far higher than the cost of professional advice up front.

What we focus on at It's Simple Will #

The will-creation flow at It's Simple Will covers the testamentary trusts most Canadian households actually need — minor-children trusts, age-graduated distributions, and discretionary trusts for vulnerable adults — without pretending to replace the lawyer-and-accountant conversation those structures sometimes require. For the bigger picture, see our pillar on estate planning in Canada and the related articles on the Henson trust and testamentary trusts in a Canadian will.
