Key takeaways
  • When investing trust property, a trustee must use the care, skill, diligence and judgment of a prudent investor.
  • Estate trustees must keep accurate records of the estate's assets and transactions, and accounts filed with the court must show assets, money received, liabilities and the compensation claimed.
  • An executor who has started to act cannot simply retire by deed; stepping down requires a court application.

Some wills do more than divide assets. They set up a trust, for example to hold money for a young child until a set age, or to provide for a surviving spouse over time. The person named as executor is often also named as trustee of that trust.

That role can last years after the estate itself is settled. This article outlines the ongoing duties around investing, record keeping, tax filings and accounting, and what to do if the job becomes too much.

Taking on the role, and leaving it

A person named as estate trustee in a will does not have to act. If you are named, think carefully about whether you can manage a long-term responsibility before you step forward.

Once you have acted, leaving is harder. The Trustee Act procedure for a trustee to retire by deed does not apply to executors or administrators, so an executor who wants to step down after acting must apply to court. The court may also remove a personal representative on any ground on which it may remove any other trustee and appoint another proper person, and any person interested in the estate, or an executor who wants to be relieved, may apply.

Investing trust property

In investing estate property, a trustee must exercise the care, skill, diligence and judgment of a prudent investor. In plain terms, you are not expected to chase high returns, but you are expected to act thoughtfully and be able to show your reasoning.

The will itself may give extra directions or limits, so read the trust terms closely.

Records, expenses and accounts

Estate trustees must keep accurate records of the estate's assets and transactions. Accounts filed with the court must include assets at the date of death, all money received, all liabilities and a statement of the compensation the trustee claims.

If you believe an expense is properly incurred in carrying out the trust, you may pay it from estate property, or pay it personally and recover it from the estate, but the court may later disallow the payment or recovery. Keep receipts and the reason for each payment.

A beneficiary is an interested person who can compel accounts. A person with a financial interest may also move for an order requiring the trustee to give a statement of the assets, further particulars, or to pass accounts. Passing accounts means filing accounts verified by affidavit (Form 74.43) and the other required documents, serving every person with a contingent or vested interest at least 60 days before the hearing, or 75 days if served outside Ontario. A beneficiary who objects must serve a Notice of Objection to Accounts (Form 74.45) at least 35 days before the hearing.

Where children under 18 are beneficiaries, the Office of the Children's Lawyer may act on their behalf in estate matters.

Compensation and tax

An estate trustee is entitled to a fair and reasonable allowance for care, pains and trouble and time spent, as allowed by a judge of the Superior Court of Justice. The statute sets no percentage or formula. This does not apply where the will itself fixes the allowance. Where a lawyer is the trustee and has provided necessary professional services, the allowance may be increased.

On the tax side, a trust return (T3) must generally be filed no later than 90 days after the trust's tax year-end, with any balance owing due within the same 90 days. A trust must file if its total income from all sources is more than $500, or if it makes a capital distribution to beneficiaries. These filing rules changed for trust tax years ending on or after December 31, 2023.

An estate can be a graduated rate estate for no more than 36 months after the death. A graduated rate estate may have a non-calendar tax year, while other trusts generally must use a December 31 year-end. Ask an accountant how your trust is classified and when its year ends.

What to do next

If you act honestly and reasonably, the court has power to relieve a trustee of personal liability for a breach of trust where they ought fairly to be excused. It is a discretion, so good habits matter more than relying on it.

Frequently asked questions

Do I have to accept the role of trustee named in the will?

No. A person named as estate trustee in a will does not have to act. Think about it before you take any steps as executor, and get advice if you are unsure.

Can I resign later if the trust becomes too much?

An executor who has started to act cannot retire by deed. Stepping down requires an application to court.

Can a beneficiary ask to see my accounts?

Yes. A beneficiary is an interested person who can compel accounts, and a person with a financial interest may move for an order requiring the trustee to pass accounts.

How should I invest the trust money?

You must use the care, skill, diligence and judgment of a prudent investor. The right mix depends on the trust's purpose and terms, so a lawyer or qualified investment adviser can help.
