Ask what a trust is for and most people will say avoiding tax. That is mostly wrong in Canada, and the families who benefit from trusts are the ones who understand what the tool actually does: it separates control of an asset from its enjoyment. A trustee controls; beneficiaries benefit. Everything a trust legitimately achieves, protecting heirs from themselves or others, managing wealth for those who cannot, keeping a family business governable, smoothing an estate, flows from that separation. The tax rules mostly limit rather than create the advantages, and candid professional guidance says as much.
The rules that shape everything
Three features of Canadian trust taxation set the boundaries. First, most inter vivos trusts pay tax at the top marginal rate on income they retain, so trusts are generally not a vehicle for accumulating lightly taxed income; income is usually paid or made payable to beneficiaries and taxed in their hands. Second, attribution rules can tax income from property you transfer into a trust back to you where spouses or minor children benefit, which is why casual income-splitting through trusts largely stopped working long ago, and the tax on split income rules closed most of what remained for private company income. Third, and most important for planning, the 21-year rule: a trust is deemed to dispose of its capital property at fair market value every 21 years, triggering tax on accrued gains. A trust is therefore not a place where gains hide forever; it is a place where they are scheduled. Well-run trusts plan for year 21 from the day they are settled, typically by rolling assets out to Canadian resident beneficiaries before the anniversary when that fits the family's intentions.
The alter ego trust: probate planning for the 65-plus
One trust deserves particular attention for Canadians over 65, because it solves a specific, expensive, public problem: probate. When an estate passes by will, provincial fees apply, roughly 1.5 per cent of estate value above a small threshold in Ontario, and the will becomes a public court document, with the estate frozen while probate is processed.
An alter ego trust, or a joint partner trust for a couple, is an inter vivos trust available where the settlor is at least 65. Its defining feature is the rollover: you can transfer assets into the trust at cost, with no deemed disposition on the way in, something no ordinary trust permits. You remain entitled to all the income for life, retain effective control as trustee, and on death the assets pass to your chosen beneficiaries under the trust's terms, outside the will. No probate fee on those assets, no public disclosure, no estate freeze-up, and meaningfully better protection against the will challenges that increasingly follow blended families and unequal bequests.
The costs are real but knowable: legal setup, an annual trust return, and, at death, a deemed disposition inside the trust that taxes the accrued gains much as the estate would have been taxed. The 21-year rule, notably, does not apply until after the settlor's death. For Ontarians over 65 with substantial non-registered portfolios or private company shares, the arithmetic frequently favours the trust; for families whose wealth sits mainly in registered accounts and a principal residence, designations and joint ownership may achieve most of the benefit with less machinery. This is precisely the calculation to run with your advisors rather than assume in either direction.
Where family trusts still earn their keep
Beyond probate, four uses justify the ongoing compliance of a discretionary family trust. In an estate freeze, the trust holds the new growth shares of a private company, keeping tomorrow's growth flexible among children and grandchildren without today deciding who gets what, and, where the shares qualify, potentially multiplying access to the lifetime capital gains exemption across beneficiaries at a future sale, subject to the technical rules your accountant will steward. For beneficiaries who should not yet, or ever, control capital, minors, spendthrift heirs, family members with disabilities, where a properly structured trust can also preserve provincial disability benefits, the trustee's control is the entire point. For privacy and continuity across generations, a trust holds assets together where an outright bequest would scatter them. And in second marriages, a spousal trust can support a surviving spouse for life while guaranteeing the capital ultimately reaches the children of the first marriage, an arrangement no will alone can enforce as cleanly.
What trusts no longer do is conjure tax savings from nothing. The honest modern case for a family trust is control, protection, privacy and orderly succession, with tax outcomes that are managed rather than magical.
Getting it right
Trusts fail in practice for mundane reasons: settled and then ignored, trustees who never meet, no minutes, no plan for year 21, portfolios inside the trust run with no reference to its purpose. A trust is a small institution, and it needs what institutions need: a written investment policy matched to the beneficiaries' horizon, annual attention, and coordination among the lawyer who drafted it, the accountant who files for it, and the manager who invests for it.
BlueSky Investment Counsel manages portfolios for family trusts, alter ego trusts and estates, and works alongside your lawyer and accountant so the investing serves the structure rather than ignoring it. If your family uses a trust, or is weighing one, a complimentary Second-Opinion Portfolio Review of the assets involved is a practical place to start.
