What Is a Certificate of Appointment of Estate Trustee in Ontario?

A North York widow walks into her late husband's bank with a death certificate and the will, expecting to close his account. The teller asks for the Certificate of Appointment of Estate Trustee. She looks blank — the lawyer who drew up the will never used that phrase. Two weeks and one Google search later she's looking at Form 74A, an Estate Administration Tax calculation, and a 6-to-8-week wait. The Ontario probate vocabulary trips up more first-time executors than any other piece of the process.

This guide walks through what the Certificate of Appointment actually is, the forms and steps to get one, the Estate Administration Tax that runs in parallel, and where the Small Estate Certificate route applies. For the broader context, see our pillar guide on what probate is in Canada.

What the Certificate of Appointment actually does #

The certificate is the Superior Court of Justice's confirmation that a specific person has legal authority to step into the deceased's shoes for the limited purpose of administering the estate. Banks rely on it before releasing accounts. The Land Registry Office requires it before transferring title out of the deceased's name. The certificate does not give the estate trustee ownership of the assets — it gives them authority to collect, manage, and distribute the assets according to the will (or to the intestacy rules in the Succession Law Reform Act^[6] if there is no will).

Ontario uses three flavours:

• Certificate of Appointment of Estate Trustee With a Will — issued where there is a valid will. The named executor applies.
• Certificate of Appointment of Estate Trustee Without a Will — issued where there is no will or the named executors cannot or will not act. A statutory priority list determines who can apply (the surviving spouse first, then adult children, etc.) under the Estates Act^[3] and Rule 74.^[1]
• Small Estate Certificate — introduced effective April 1, 2021 for estates valued at $150,000 or less. A simpler procedure using Forms 74.1A through 74.1F.

The application — forms and what they do #

The Rule 74 forms framework is the backbone of every Ontario probate application.^[5]

Form 74A — Application for a Certificate of Appointment of Estate Trustee. Since a 2025 update to the estate forms, this single application is used whether or not there is a Will (it replaced the earlier separate with-a-will and without-a-will application forms). Signed by the proposed estate trustee, it identifies the deceased, the will if there is one, the beneficiaries, the estate value, and the calculated Estate Administration Tax.

Form 74B / 74B.1 — Affidavit of Service / Lawyer's Certificate of Service. Proves every beneficiary, every person with a financial interest, and every relevant party has been notified of the application before the court considers it.

Form 74C — Certificate of Appointment of Estate Trustee. The certificate itself, issued by the registrar once the application is approved.

Form 74D / 74E / 74F — Supporting affidavits about the will. Affidavit of Execution of Will or Codicil (74D), Affidavit of Condition of Will or Codicil (74E), and Affidavit Regarding a Holograph Will or Codicil (74F).

Form 74G — Renunciation and Consent. Used when a named executor declines to act, or when someone with an equal or prior right to apply consents to the applicant's appointment — clearing the path in both with-a-will and without-a-will applications.

The application bundle, the original will, the death certificate, and the EAT payment all go to the Superior Court of Justice registry for the county or district where the deceased lived at death. Filing is now accepted by email, regular mail, or in person.^[4]

Estate Administration Tax — the other side of the form #

When the application requests the certificate, Ontario's Estate Administration Tax^[2] is calculated and paid. The structure:

• $5 per $1,000 (0.5%) on the first $50,000 of estate value — often effectively waived since 2020 for estates valued at $50,000 or less
• $15 per $1,000 (1.5%) on every dollar above $50,000
• No cap — a $2,000,000 estate pays roughly $29,250 in EAT

The tax is paid out of estate assets, not by the estate trustee personally. The amount paid is provisional — the estate trustee must file an Estate Information Return within 180 days of the certificate's issuance confirming the asset values. If the values change, the tax is reconciled. For a side-by-side comparison with other provinces, see probate fees across Canada and our probate fee calculator.

How long the process actually takes #

The clean version: 6 to 8 weeks from complete application to certificate, plus the pre-application work and the post-certificate Estate Information Return.

Pre-application (typically 2 to 8 weeks). Locate the original will, gather the death certificate, value every asset and debt as of the date of death, identify and notify every beneficiary, assemble the affidavits.

At the registry (typically 6 to 12 weeks). The Superior Court of Justice processes the application. Toronto, Newmarket, Brampton, and Ottawa registries are generally busier than smaller-county registries. Applications that are returned for corrections add 4 to 8 weeks per round-trip.

Post-certificate (180 days for the Estate Information Return, 6 to 12 months for CRA clearance). Distribution is risky until both the EIR is filed and the CRA clearance certificate has been issued.

A typical clean Ontario estate runs 9 to 18 months from death to final distribution.

The Small Estate Certificate path #

For estates valued at $150,000 or less, the Small Estate Certificate procedure is substantially lighter. The forms (74.1A through 74.1F) cut the number of required affidavits. The Estate Administration Tax still applies, but the practical cost of getting the certificate is lower — a self-represented applicant can plausibly handle a Small Estate Certificate application without a lawyer, where a full Certificate of Appointment usually warrants legal help.

The threshold is meaningful — about a third of Ontario estates that go through any probate process at all qualify. If you're administering a small estate, ask the registry whether the Small Estate Certificate route applies before defaulting to a full Form 74A application.

What slows an Ontario probate down #

The recurring causes:

• Missing affidavits. The most common cause of a registry returning an application. Affidavit of Execution is the usual culprit — many older wills don't have one prepared, and the witnesses can be hard to locate decades later.
• Wrong beneficiary list. Every beneficiary must be served. Missing one — including disinherited children, who are still entitled to notice in many circumstances — causes the application to come back.
• Inventory errors. Real-estate values that aren't supportable, missed accounts, or an inventory that excludes assets passing outside the estate (joint property, beneficiary-designated accounts) all cause problems.
• EAT calculation disputes. Especially around the deceased's home value or business interests.
