Can an Estate Trustee Be Removed in Ontario? What the Courts Require

Can an Ontario court remove an estate trustee?

Yes — but the threshold is deliberately high. Ontario courts will not remove an estate trustee simply because beneficiaries are unhappy or suspicious. The Court of Appeal confirmed this principle in Staples v. Jean, 2026 ONCA 369 (CanLII), dismissing an appeal that sought to oust the trustee over alleged conflicts of interest and a disputed will interpretation.

What does “high threshold” actually mean for beneficiaries?

A high threshold means that dissatisfaction alone is not enough to remove an estate trustee. Courts look for evidence that the trustee’s conduct has endangered the estate, that there is a real and serious conflict that cannot be managed any other way, or that the trustee is failing to carry out their duties. Unhappiness about decisions, personality clashes, or even a potential conflict of interest will not automatically tip the scales toward removal.

In this case, the motion judge declined to remove the trustee and instead gave practical directions to guide the administration going forward and to address the conflict concerns that had been raised. The Court of Appeal found no reviewable error in that approach and upheld it as reasonable in the circumstances.

Does a conflict of interest automatically remove an estate trustee in Ontario?

No — a conflict of interest is a serious concern, but it does not automatically lead to removal. The court will first consider whether the conflict can be managed through directions, conditions, or other safeguards that protect the estate without the disruption and cost of replacing the trustee entirely.

Replacing a trustee mid-administration is expensive and can delay distributions to beneficiaries. The Court of Appeal confirmed that the cost of bringing in a replacement trustee is not a deciding factor on its own — but the practical disruption is part of the broader picture courts weigh when deciding whether removal is truly necessary.

What is a hotchpot clause and why does it matter?

A hotchpot clause is a provision in a will that requires a beneficiary who has already received a gift or advance from the estate to bring that earlier benefit into account before taking their share of what remains. In plain terms: if you already got something, you have to “top up” the pot before you can take more.

In Staples v. Jean, the wills contained hotchpot clauses that applied across both a primary and a secondary will. The appellants challenged how the motion judge interpreted those clauses — but then conceded on appeal that the motion judge’s reading was correct. The Court of Appeal adopted the interpretation that the estate trustee had been applying all along. The lesson for anyone drafting or administering a will with multiple documents: hotchpot clauses need to be read together carefully, and the trustee’s reasonable interpretation will carry significant weight.

Can you raise a new legal argument for the first time on appeal?

Generally, no. Ontario’s Court of Appeal is reluctant to consider issues that were never put before the lower court. In this case, the appellants tried to raise a new argument about how shares in a holding company should be dealt with. Because that issue was not argued before the motion judge and was not included in the notice of appeal, the Court of Appeal declined to address it entirely.

This is an important procedural lesson: if you have a legal argument, you must raise it at the first opportunity. Saving arguments for appeal — or forgetting to include them in your appeal documents — means the court will likely refuse to hear them.

What standard does the Court of Appeal use to review a trustee removal decision?

The Court of Appeal gives significant deference to the motion judge’s decision on whether to remove a trustee. That means the appellate court will not substitute its own view simply because it might have decided differently. The reviewing court is looking for a genuine legal error or a decision that is clearly unreasonable — not just a different outcome.

In Staples v. Jean, the Court of Appeal found no such error. The motion judge’s directions were described as practical and appropriate, and the appeal was dismissed on all grounds.

Practical takeaways for estate beneficiaries

• Removal is a last resort. If you believe the trustee has a conflict of interest, courts will usually prefer to impose directions or conditions rather than remove the trustee outright. Gather clear evidence before bringing a removal motion.
• Raise every argument early. Any legal issue you want addressed — including how assets like company shares are treated — must be raised before the motion judge. You cannot save arguments for appeal.
• Understand hotchpot clauses before distributions begin. If the will contains a hotchpot clause, get legal advice on how it applies across all will documents before any gifts or advances are made.
• Trustee interpretation carries weight. Where a will is ambiguous, the trustee’s reasonable interpretation will be given serious consideration by the courts. Challenge it promptly if you disagree.
• Cost of a replacement trustee is not decisive. Do not assume courts will refuse removal just because it is expensive — but do expect the court to weigh the practical impact on the estate and beneficiaries.
