Two different jobs: passing your own assets quietly, or moving growth to your family
The confusion in your question is the market's fault, not yours: both structures get called trusts, both involve lawyers and deeds, and both get pitched to business owners, but they exist for opposite purposes. An alter ego trust is about you. It reorganizes how your own assets are held so that, at your death, they pass under the trust deed instead of your will, skipping probate, staying private and providing for incapacity along the way. Nobody else benefits from it while you live; that restriction is not a drawback, it is the defining condition.
A family trust points the other way. It exists so that value, almost always the future growth of your company, accrues to your family rather than to you, while you keep control. You are typically not even a meaningful beneficiary; you are the trustee steering it. Everything the family trust is good at, multiplying the capital gains exemption on a sale, holding growth after a freeze, deferring the decision of which child gets what, flows from the fact that the value is no longer yours.
So the question is not which trust is better, and anyone comparing their fees side by side is measuring the wrong thing. The question is which handover you are planning: your assets to your estate, or your company's future to your family. Answer that, and the structure picks itself. The rest of this page describes each tool honestly, puts them side by side, and finishes with the facts that tell you which one, or which two, your situation is actually asking for.
The alter ego trust: a probate and incapacity tool for owners 65 and over
An alter ego trust is available once you are 65, and its opening move is the attractive part: you can transfer your own assets into it at cost, with no immediate tax, because the law treats it as you continuing to hold your own property in a different wrapper. During your lifetime, all the income must go to you and nobody else may touch income or capital. It is, functionally, you, which is where the name comes from.
What it buys is administrative, and for larger estates the arithmetic is real. Assets in the trust do not pass under your will, so they avoid probate entirely, which in Ontario means skipping estate administration tax of roughly 1.5 per cent of estate value above $50,000, avoiding the delay of the court process, and keeping the details out of the public probate file. The deed also names who manages the assets if you lose capacity, which is often the quietly decisive benefit: a working substitute for a power of attorney, already funded, already in motion.
What it does not buy is income tax savings, and an honest advisor says so up front. The trust's income is taxed in your hands while you live, exactly as before. At your death, the trust faces a deemed disposition of its assets at fair market value, the same reckoning your estate would have faced, with the tax paid inside the trust. The 21-year rule that haunts family trusts does not apply during your lifetime; death is the trust's tax event. You have changed the route your assets take and the paperwork they generate, not the income tax bill along the way.
One fit note for business owners: an alter ego trust suits the personal side of your balance sheet, the investment portfolio, real estate, sometimes fixed-value freeze shares, far better than it suits growth you intend your children to have. Growth parked in a trust that can only ever benefit you has simply postponed the family handover. If you are married, the same tool comes in a two-person version, compared properly in joint spousal trust vs family trust.
The family trust: a container for value you are giving away
A family trust is a discretionary structure whose beneficiaries are your spouse, children, often future grandchildren and usually a holding company, and its whole point is that the value inside it is destined for them, not you. There is no age requirement and no rollover on the way in: transferring existing assets to it is a disposition at fair market value. That is why, in practice, the trust rarely buys anything. It subscribes for new growth shares for a nominal amount after an estate freeze, and everything the company becomes worth afterward accrues inside it.
Its strengths are exit-shaped. On a sale of qualifying small business shares, the trustees can allocate the gain among Canadian-resident beneficiaries so that each claims their own lifetime capital gains exemption, currently up to $1.25 million of qualifying gain per person, several exemptions instead of one. Between now and that exit, the discretionary design lets you defer deciding which child gets what, and value sitting in the trust has not vested in any child, which matters if a marriage or a business venture of theirs goes wrong. The full case, including the years it is not worth it, is in our honest assessment of family trusts.
Its costs are recurring and its clocks are real. An annual T3 return with expanded beneficial ownership disclosure, trustee resolutions behind every allocation, and the 21-year deemed disposition, which forces the trust to roll its property out to beneficiaries, and therefore finally decide the who-gets-what question, before its 21st anniversary. A family trust is not a set-and-forget document; it is a small administrative machine that pays for itself only if the exit it was built for actually arrives.
Side by side: what each trust can and cannot do
Put the two tools in the same frame and the pattern is hard to miss: every row is really the same row, yourself versus your family.
| Question | Alter ego trust | Family trust |
|---|---|---|
| Who can benefit while you live | Only you; that restriction is mandatory | Anyone named in the deed, at the trustees' discretion |
| Age requirement | You must be 65 or older | None |
| Tax on assets going in | Roll in at cost, no immediate tax | Fair market value on the way in, so it holds new growth shares instead of existing assets |
| Probate on death | Avoided for everything the trust holds; this is the headline benefit | Trust assets sit outside your estate too, but as a side effect, not the purpose |
| Multiplying the capital gains exemption | No | Yes, across qualifying Canadian-resident beneficiaries on a sale |
| The 21-year deemed disposition | Does not apply during your lifetime; the tax event is your death | Applies; plan the rollout from about year fifteen |
| What it replaces | Much of your will, and part of a power of attorney | Nothing; it adds a structure your estate plan must accommodate |
Read the last row twice, because it carries the practical warning. An alter ego trust simplifies your estate; a family trust complicates it in exchange for exit value. Choosing between them by fee quote, or by whichever one an advisor happened to lead with, gets this exactly backwards.
The split income rules constrain the family trust, not the choice
If part of the appeal of a for-my-family trust is paying income to family members at their lower rates, the tax on split income rules already took most of that off the table, so do not let it drive the decision. Since 2018, dividends a family trust allocates to your spouse or adult children are taxed at the top marginal rate unless the recipient fits an exclusion: chiefly, genuinely working in the business around twenty hours a week in the current year or any five earlier years, or the relief for amounts to your spouse once you have reached 65.
The alter ego trust never played this game; by design it pays only you, so there is nothing to split and nothing for the rules to catch. The family trust's surviving tax value is capital, not income: exemption multiplication on a sale, and gains eligible for the exemption sit outside the split income rules entirely. So the comparison stands even after 2018, it is just cleaner: the alter ego trust is estate administration, the family trust is exit planning, and neither is an income-splitting scheme anymore.
Which one fits, and when the honest answer is both
Your facts decide this in about five questions, the same ones we ask in the first meeting:
- Your age. Under 65, the alter ego trust is simply unavailable, and the question collapses to whether a family trust is worth it yet.
- Whether a sale or succession of the business is plausible. A realistic exit at a meaningful gain is the family trust's whole case. No exit, weak case.
- The size of your personal estate. Probate savings scale with what passes through your will; a large portfolio and real estate make the alter ego trust's arithmetic compelling, a modest estate does not.
- Who needs the value. If the goal is providing for children and grandchildren during your lifetime, only the family trust can do it. If the goal is an orderly, private estate, only the alter ego trust is built for that.
- Your appetite for administration. The family trust brings annual filings and trustee duties for decades. The alter ego trust is nearer to a one-time reorganization with light upkeep.
For an owner at 65 with a valuable company and a real personal portfolio, the answer is often both, doing different jobs on different floors: a family trust holding the growth shares of the business since the freeze, and an alter ego trust holding the personal assets, including, sometimes, the fixed-value freeze shares, so your own estate passes without probate. The structures do not compete; they stack, and where a holding company sits in that stack is its own question, mapped in family trust or holding company.
Sequencing is where a business estate planning CPA in Ontario earns the fee: the freeze needs a valuation, the family trust should exist before the growth it is meant to catch, the alter ego trust must not accidentally swallow shares the succession plan needs elsewhere, and the will, the deeds and the shareholder agreement have to tell one consistent story. A lawyer drafts the deeds; we design the tax architecture, run the valuations and carry the annual filings, as defined-scope work under Strategic Projects within our estate planning practice.
If you are staring at a proposal for one trust and wondering whether it should have been the other, that is precisely a 15-minute conversation. The discovery call is free, and the most common outcome is not a sale; it is a clear answer about which job actually needs doing first.
