Yes, and the deed you sign will almost certainly include them
Start with what the law permits, which is nearly everything: a trust's beneficiaries are whoever the deed names, and spouses sit in the standard class alongside children, grandchildren and usually a corporate beneficiary. There is no rule against it, no filing triggered by it, and no tax cost to their mere presence on the list. A discretionary beneficiary who is never paid anything has received nothing and is taxed on nothing.
Including the spouse buys the trustees options. It lets the trust direct income to them in the years the rules allow it at their rates, include them in a capital gains exemption multiplication on a sale, and receive trust capital if the family ever wants value in their hands. It also builds in flexibility for your death: a spouse who is a beneficiary can be supported by the trust without the shares ever passing through your estate. Leaving the spouse out is the unusual drafting choice, typically made in second marriages or where a marriage contract says so.
So the yes is easy. What your search is really asking, whether the trust can move income to your spouse and save tax, is where the three rule sets come in, and each one polices a different thing.
The three rules that police what your spouse receives
Each rule watches a different flow, and confusing them is how bad advice gets made, so here they are side by side:
| Rule | What it watches | What it does | What keeps you out of it |
|---|---|---|---|
| Tax on split income | Private-company dividends the trust allocates to your spouse | Taxes the allocation at the top marginal rate regardless of their bracket | Spouse genuinely works in the business about 20 hours a week, or you have reached 65, or the amount is an exemption-eligible capital gain |
| Spousal attribution | Income from property you transferred or lent, directly or via the trust | Taxes that income back on your return, not theirs | Clean settlement by a third party; you do not fund the trust yourself |
| Corporate attribution | Estate freezes where a spouse or minor is a beneficiary and the company stops qualifying as a small business corporation | Can tax you annually on a deemed return on the frozen value | Keeping the company onside as a small business corporation, checked every year |
Notice the pattern: none of these rules forbids anything. They reassign the tax so the shift is not worth doing, which is a polite Canadian way of forbidding it. Planning with a spouse in the trust is therefore about finding the flows the rules leave alone, which is the next section.
Notice also that two of the three rules are about where the property came from, not where the income goes. This is why the trust is settled by an outsider with a token gift, why you lend to the trust only on commercial terms if at all, and why the freeze design gets tested against small-business-corporation status at the start and each year after. The mechanics of the whole who-pays system are traced in how family trusts are taxed in Canada.
What actually works: the payments that survive the rules
Four flows to a spouse hold up. First, compensation for real work: if your spouse genuinely works in the business on a regular basis, around 20 hours a week in the current year or any five past years, dividend allocations to them are excluded from the split-income rules and taxed at their own rates. The five-year memory means a spouse who worked in the early years may qualify long after stepping back, provided the hours were real and you can show them.
Second, the age-65 relief: once the business owner turns 65, allocations to their spouse escape the split-income rules, deliberately mirroring how pension income splitting works for retirees. For owner families in their fifties building a trust today, this is not a loophole but the design: the structure that feels constrained now becomes a retirement income splitter on schedule.
Third, the exit event: capital gains that qualify for the lifetime capital gains exemption are outside the split-income rules entirely, so on a sale the trustees can allocate gain to your spouse and their own exemption, up to $1.25 million, shelters it. A spouse in the trust is one more exemption on sale day, which for many families is the single largest benefit the trust ever delivers, and a core reason a trust holds the shares in the first place.
Fourth, capital rather than income: the trustees can distribute trust capital to a spouse beneficiary, which is not an income allocation at all. Whether that is wise touches attribution history and family-law exposure, so it is a decision made with advisors, but it is a real lever the deed provides.
Separation, death, and how the deed defines "spouse"
The word spouse in a deed is drafting, not biology, and it decides what happens when the marriage changes. Well-drafted deeds define the spouse by reference to the relationship at the time of a distribution, or name the person and exclude them upon separation, so an ex-spouse does not remain a beneficiary by accident. If your deed simply names your spouse with no exit language, a separation leaves them on the list until the deed's mechanisms, or a court, deal with it. This is worth checking now, while it is hypothetical.
In a separation, a discretionary interest is not divided like a bank account, but family law can treat it as relevant financial context, and trust structures do not override equalization rules. The honest framing: the trust contains value away from both spouses individually, which helps, and a marriage contract plus deliberate deed drafting help more. Specific exposure is a family lawyer's question, asked before signing rather than after.
On death the trust shows its worth. A spouse who is a beneficiary can be supported by trustee allocations without the company's shares entering your estate, probate or Ontario's estate administration tax, and the deed, not your will, governs. Coordination still matters: your will, the deed and any shareholders' agreement have to tell one story, which is a coordination job we run inside estate planning engagements for exactly these families.
The facts that change the answer
Whether naming your spouse is merely fine or genuinely valuable turns on a short list. Whether they work in the business now, or credibly did for five past years, with evidence. Your age, because 65 flips the default answer for dividends. Whether a sale at a meaningful gain is plausible, which sets the value of their exemption on exit. The stability of the marriage and the existence of a marriage contract, which set the family-law stakes. Whether the company reliably qualifies as a small business corporation, which controls the corporate attribution risk. And who funded the trust, because attribution follows the property forever.
If you are designing the trust now, the sequencing is simple: decide the beneficiary list with both the tax rules and the family-law questions on the table, settle it cleanly, and revisit the deed when the marriage, the residence of beneficiaries or the business changes.
