Funding a Trust in Canada — Getting Assets In Without a Tax Surprise
People focus on creating a trust — the deed, the trustees, the lawyer's bill — and overlook the step that actually makes it real: putting assets into it. Funding is where the tax happens, and where well-intentioned plans quietly self-destruct. Transfer the wrong asset the wrong way, or let the wrong person fund it, and you can trigger a capital gain you did not expect or hand the tax back to yourself through the attribution rules. The mechanics of getting assets in deserve as much care as the decision to set the trust up.
This guide explains how trusts are funded and the tax that comes with it. It is general information, not advice; trust funding is technical and belongs with a tax professional.
What funding means
A trust is a legal relationship in which a trustee holds property for beneficiaries — and until property is actually transferred to the trustee, there is nothing for the trust to govern. Funding is that transfer: an initial settlement amount to bring the trust into existence, and later contributions of cash or property. An unfunded trust is just a document.
The deemed disposition on funding
Here is the first tax point. Transferring appreciated capital property into most trusts is treated as a disposition at fair market value, so the contributor may realize a capital gain on the way in.[1][2] Cash, having no accrued gain, transfers cleanly. The exceptions are the tax-deferred rollovers available to alter ego, joint partner, and spousal trusts, which let qualifying property transfer at cost. So funding a discretionary family trust with a long-held appreciated stock portfolio can itself trigger tax — a surprise worth planning around.
The attribution traps
The rules that most often defeat a trust are the attribution rules. The central one is the reversionary-trust rule: if the person who contributes property — or their spouse — can receive that property back, or retains control over how it is dealt with, the trust's income and capital gains can be attributed back to the contributor and taxed in their hands.[1] Funding a trust carelessly can therefore cancel its entire tax rationale. This is why the settlor is typically an arm's-length person who makes only a small initial gift and is not a beneficiary, with later contributions and benefits structured carefully around these rules.
Funding later, and the 21-year clock
Trusts can take further contributions over time, but each transfer of appreciated property is its own deemed disposition, and each must be tested against the attribution rules — later funding deserves the same care as the first. And remember the 21-year clock starts at creation, not at each contribution, so fund and plan with that eventual deemed-disposition date in mind; see the 21-year rule.
What we focus on at It's Simple Will
The Will Creator covers the wills that suit most Canadians, whose plans do not involve funding a trust. Where a trust is part of your strategy, funding it correctly is a tax-planning exercise for an accountant and lawyer, and a place where mistakes are expensive.

Frequently asked questions
What does it mean to fund a trust?
To transfer assets to the trustee to hold under the trust deed. A trust is a legal relationship, not a container — until property is actually conveyed to the trustee, the trust is an empty framework. Funding can be the initial settlement amount and later contributions of cash or property.
Is there tax on transferring assets into a trust?
Often, yes. Transferring appreciated capital property to most trusts is treated as a disposition at fair market value, so the contributor may realize a capital gain on the transfer in. Cash carries no such gain. The exceptions are tax-deferred rollovers available to alter ego, joint partner, and spousal trusts, which can transfer at cost.
What are the attribution traps when funding a trust?
The main one is the reversionary-trust rule: if the person who contributes property, or their spouse, can receive it back or control how it is dealt with, the trust's income and capital gains can be attributed back to that contributor and taxed in their hands. Funding a trust carelessly can therefore defeat its tax purpose entirely.
Who should the settlor be?
Typically someone who makes only a small, initial gift to settle the trust and who is not a beneficiary — often an arm's-length person — precisely to avoid the attribution and control problems. The people who later contribute larger amounts and the people who benefit need to be structured carefully around the attribution rules.
Can I add assets to a trust later?
Yes, trusts can receive further contributions, but each transfer of appreciated property is its own deemed disposition, and each contribution must be considered against the attribution rules. Later funding should be planned with the same care as the initial settlement, not done casually.
When does the 21-year clock start?
At the trust's creation. The 21-year deemed-disposition clock runs from when the trust is settled, regardless of when particular assets are contributed, so funding decisions should be made with that eventual date in mind. Record the creation date and plan well ahead of the anniversary.
