Do I need a trust, and how does it work in Ontario?

A trust is a relationship, not a business or an account. One person (the settlor) transfers property to another person or corporation (the trustee), who holds and manages it for the benefit of someone else (the beneficiary). The trustee becomes the legal owner on paper — the deed, the bank account, the share certificate sits in their name — while the beneficiary holds the benefit of it, on the terms the settlor set out.

That split between legal ownership and the benefit of ownership is what makes a trust different from simply giving something away or adding someone to title. Most Ontario families never need one: a will, correct beneficiary designations and powers of attorney cover the great majority of estate plans. A trust earns its place when property needs to be managed for someone over time, rather than handed over all at once.

A trust for minor children holds an inheritance until they reach an age the settlor chooses, rather than handing a lump sum to an eighteen-year-old. A trust for a beneficiary with a disability can be structured with that beneficiary's own support and benefits in mind. Blended families sometimes use a trust to give a surviving spouse the use of a home or income for life while preserving the capital for children from an earlier relationship. Business owners use trusts in succession and income-splitting plans around a private corporation, and some families want a specific asset — a cottage, an investment portfolio — managed under clear rules instead of informal joint ownership.

None of these are the only way to reach the goal: a will with conditions, a beneficiary designation or a life-interest clause can sometimes do similar work more simply, which is why the right structure depends on the specific problem, not a general preference for "having a trust."

An inter vivos trust (sometimes called a living trust) is set up while the settlor is alive, by transferring property into it now. It can start working immediately and continues on its own terms regardless of what happens to the settlor's will. A testamentary trust is created by a will and only comes into existence on death; it holds a share of the estate rather than property moved in advance.

The tax treatment differs too. For up to 36 months after the death, an estate can qualify as a "graduated rate estate" and be taxed at the same graduated rates as an individual; outside that window, and for most inter vivos trusts throughout, trust income that isn't paid out to a beneficiary is generally taxed at the highest flat rate. Both kinds are still useful for the same non-tax reasons — controlling timing or protecting a beneficiary — the choice mostly comes down to whether the property needs managing now or only after death.

A trustee is a fiduciary: someone who must act in the beneficiaries' best interests, not their own. Ontario's Trustee Act sets a "prudent investor" standard for how a trustee invests trust property — the care, skill and judgment a prudent investor would use, weighing the trust's need for income, inflation and expected tax consequences, and diversifying to a degree appropriate to the trust. A trustee who follows a reasonable, documented plan is generally protected even if one investment loses money.

Trustees must also keep proper accounts and can be asked to formally "pass" them before a judge; if the trust document doesn't set compensation, a judge fixes a fair and reasonable amount for the care, time and trouble the role took. Anyone the settlor trusts can generally act as trustee — a family member, a friend, an accountant or a trust company — but the role carries real legal exposure, which is why many settlors name more than one trustee rather than leaving sole control with one person.

A trust is generally its own taxpayer, separate from the settlor and the beneficiaries, and most trusts have to file an annual return. Trust income kept inside the trust, rather than paid out, is usually taxed at the highest personal rate — outside a testamentary trust's first 36 months as a graduated rate estate — which is why many trusts are structured to pay income out to beneficiaries who are taxed at their own, often lower, rate instead.

Because the rules turn on drafting details and a family's own numbers, this is where a lawyer works alongside an accountant, not instead of one; a trust's ongoing filing obligations are part of what it costs to keep running, not a one-time cost at signing.

Most Ontario estate plans don't need a trust — a well-drafted will, correct beneficiary designations and powers of attorney do the job for most families. A trust earns its cost and complexity when there's a specific problem it solves: a beneficiary who can't yet, or can't ever, manage money directly; a blended family where timing matters; a business that needs an ownership structure separate from day-to-day control; or a wish to keep a specific asset under clear rules instead of informal joint ownership.

Before recommending one, a lawyer checks what you're actually trying to achieve, whether a simpler tool reaches the same result, who is realistic and willing to act as trustee, and what the trust will cost to set up and to administer every year after. See our Incapacity and Powers of Attorney guide if the problem you're actually solving is who acts for you while you're alive, not after you die.
