For many Ontario couples, the will is simple: everything to my spouse, full stop. For others, routing some or all of an inheritance through a spousal trust instead makes more sense. The two approaches aren't separated by tax savings — a common misconception — but by how much control you want to keep over what happens to your assets after your spouse no longer needs them.
Here's how the two actually compare, and how to tell which one fits your situation.
The Tax Deferral Is Available Either Way
It's worth clearing this up first: the capital gains deferral people associate with spousal planning applies whether property passes to your spouse outright or into a properly structured qualifying spousal trust. Both routes can defer the tax that would otherwise arise from the deemed disposition of your property at death, generally until your spouse later disposes of the property or dies. So the tax deferral, on its own, isn't a reason to choose one over the other — the real differences lie elsewhere.
Side-by-Side Comparison
| Outright to Spouse | Qualifying Spousal Trust | |
|---|---|---|
| Capital gains deferral | Available | Available, if the trust meets the technical conditions |
| Who controls it after your death | Your spouse, fully — it becomes their own property to spend, give away, or leave to whoever they choose | You, through the trust terms — your spouse generally receives income, while the ultimate destination of the capital is fixed by you in advance |
| Protection if your spouse remarries | None — assets given outright can eventually pass to a new spouse or their family | The trust's remainder beneficiaries (often your children) are generally locked in by the trust document, regardless of your spouse's later relationships |
| Administrative burden | None beyond normal estate administration | Ongoing — a trustee, typically separate accounting, and generally its own annual tax filings for as long as the trust exists |
| Flexibility for your spouse | Complete — no restrictions | Usually limited to income, or a defined use of specific property, depending on drafting |
When an Outright Gift Usually Makes Sense
- You and your spouse are each other's only intended beneficiaries, with no children from earlier relationships to protect
- Your spouse is fully capable of managing money and property on their own
- Simplicity and low ongoing cost matter more to you than locking in a future distribution
- You're comfortable with your spouse having complete discretion over what eventually happens to the assets, including who inherits from them
When a Spousal Trust Usually Makes Sense
- You're in a blended family and want to provide for your current spouse while guaranteeing that children from an earlier relationship eventually inherit
- You're concerned about your spouse's capacity to manage significant assets, now or as they age
- You want professional or structured management of the assets rather than leaving that entirely to your spouse
- You want to reduce the risk that the assets end up passing to a future spouse or their family instead of your own children
The Real Trade-Off
Choosing between the two isn't really about tax at all — it's about how much you're willing to trust your spouse's own future decisions versus how much you want to lock in today. An outright gift is simpler and gives your spouse complete freedom. A spousal trust costs more in complexity and ongoing administration, but it lets you set the rules for what happens after your spouse's interest ends. Neither choice is inherently right; it depends on your family, your assets, and how much certainty you want.
Frequently asked questions
Does a spousal trust mean my spouse gets less than they would outright?
Not necessarily less — a well-drafted spousal trust can still give your spouse the full income the assets generate, and sometimes the use of specific property like the family home. What's different is who controls the underlying capital, not necessarily how much your spouse benefits day to day.
Can I split my estate, leaving some assets outright and some in trust?
Yes. Many Ontario wills do exactly this — for example, leaving personal effects and a portion of savings outright, while routing a larger asset like an investment portfolio or a business interest through a spousal trust.
Is a spousal trust only relevant for large estates?
No, though the added administrative cost matters proportionally more for a smaller estate. The decision is usually driven more by family structure and control concerns than by the size of the estate alone.
If I choose an outright gift now, can I change my mind later?
Yes — you can update your will at any time while you have the capacity to do so, switching between an outright gift and a trust structure as your circumstances or intentions change.
