Ontario Probate Application: Document Checklist

Everything you need to gather to apply for a Certificate of Appointment of Estate Trustee — and where to find each piece.

Who this is for: an estate trustee (executor), or a family member expecting to become one, who needs to apply for probate in Ontario and wants to know exactly what to collect before filing. What you'll get: a stage-by-stage document checklist, a source table, and a heads-up on what causes delays.

⚖️ This is a general guide, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.

First, what is probate?

In Ontario, "probate" is the common name for getting a Certificate of Appointment of Estate Trustee from the Superior Court of Justice. The certificate is the court's confirmation that:

1. the deceased's will is valid (if there is one), and
2. the estate trustee has authority to act.

Banks, the land registry, and investment firms often won't release significant assets or transfer property until they see this certificate. Not every estate needs it — small or jointly-held estates sometimes don't — but when an institution insists, probate is the key that unlocks the assets.

When you apply, the estate pays Estate Administration Tax (Ontario's name for the probate fee), calculated on the value of the estate. The forms and process are governed by the Estates Act, the Estate Administration Tax Act, and the Rules of Civil Procedure.

⚠️ Forms and rules change. Ontario revises its estate court forms and filing procedures periodically, and Estate Administration Tax thresholds and rates are set by law. Always verify the current forms, fees, and rules with the Superior Court of Justice and the Ontario government before you file. Don't rely on an old form or figure.

Stage 1 — Confirm the death and locate the will

• Original will — not a photocopy. The court needs the original signed will.
• Any codicils — signed amendments to the will, also originals.
• Proof of death — typically the funeral director's Statement of Death and/or the Death Certificate issued by the province.
• A search for a later will — confirm you have the most recent valid will. A later will or codicil can override what you're holding.

💡 No will? You can still apply — for a Certificate of Appointment of Estate Trustee without a will (an intestacy). The document list overlaps, but with no will to name an estate trustee, who may be appointed is governed by s. 29 of the Estates Act, while who inherits is governed by the Succession Law Reform Act — and a bond is more likely to be required. Get advice.

Stage 2 — Build the asset inventory and value the estate

This is the part that takes the most time, and it drives the Estate Administration Tax.

• A complete list of estate assets the deceased owned in their own name, with date-of-death values:
  • [ ] Real estate in Ontario (use the value of the deceased's interest)
  • [ ] Bank and investment accounts
  • [ ] Vehicles, valuables, business interests
  • [ ] Other property passing under the will/intestacy
• Date-of-death valuations to support those figures — bank letters, account statements, a real-estate appraisal or assessment, business valuations.
• A list of debts (mortgages on Ontario real estate may reduce the value of that property for tax purposes — confirm the current rule).

💡 What usually stays out of the probate value: assets that pass outside the estate, such as property held in joint tenancy with right of survivorship, and registered accounts or insurance with a named beneficiary. These often don't form part of the estate that's probated — but the rules are nuanced, so confirm each asset's treatment.

⚠️ Watch out: you must value the estate honestly and reasonably. Ontario requires an Estate Information Return to be filed with the Ministry of Finance after the certificate is issued (within a set deadline — verify the current timeframe), reporting the estate's value. Under- or over-stating values has consequences. Keep your backup documents.

Stage 3 — Notify the beneficiaries

• Notice to every beneficiary named in the will (or every person entitled on an intestacy), plus anyone entitled to share, as the rules require.
• Proof that notice was sent — the court requires an affidavit or sworn statement confirming you served the required people.
• Special handling where a beneficiary is a minor or incapable adult — notice may also go to the Children's Lawyer or the Public Guardian and Trustee. Confirm who must be served.

Stage 4 — Complete the application forms

The forms differ depending on whether there's a will and whether the trustee is an individual or a company. Verify the current versions — names and numbers change.

• The main application for a Certificate of Appointment of Estate Trustee (with or without a will).
• A sworn statement / affidavit of the estate trustee confirming the facts of the application.
• An affidavit of execution of the will — sworn evidence that the will was properly signed and witnessed. If a witness signed an affidavit of execution when the will was made, you may already have it; if not, you'll need to track down a witness. (A will that is fully handwritten and signed by the deceased — a holograph will — is proved differently.)
• Draft certificate for the court to issue, if required by the current process.
• Any consents or renunciations — for example, if a named executor is stepping aside, or beneficiaries consent to your appointment.

Stage 5 — Bond (if required)

A bond (estate trustee's bond) is a form of security that protects the estate's beneficiaries and creditors against mismanagement.

• Determine whether a bond is required. It often is not required where there's a will naming a resident estate trustee, but it commonly is required for an intestacy, for a non-resident trustee, or in other circumstances.
• If required: either obtain a bond from an insurer/surety, or apply to the court to dispense with or reduce the bond (often with beneficiary consents). This can add time and cost.

💡 If a bond is a hurdle, a lawyer can often help by obtaining beneficiary consents and asking the court to dispense with it.

Stage 6 — Pay the tax and file

• Calculate the Estate Administration Tax on the estate's value. Verify the current rate and any exempt threshold — they're set by law and can change.
• Pay the required deposit on filing. In Ontario, the Estate Administration Tax is generally payable when you file the application (you can sometimes give an estimate and reconcile later, but confirm the current procedure). Budget for it.
• File with the Superior Court of Justice. Filing is generally done in the court office for the jurisdiction where the deceased lived at death (confirm the correct office and whether online filing is available).
• Keep copies of everything you file, and get certified copies of the certificate once issued, so you can give one to each institution that requires it.

Common causes of delay

⚠️ Probate timelines vary widely — and these are the usual culprits:

• The original will can't be found, only a copy. Proving a lost will is a far harder application.
• Asset values aren't ready — waiting on bank letters or an appraisal stalls everything because you can't finalize the tax.
• Wrong or outdated forms are filed and bounced back.
• A bond issue — needing one, or applying to dispense with it.
• Missing affidavit of execution because a witness can't be located.
• Disputes — a beneficiary contests the will or the appointment.
• Minors or incapable beneficiaries requiring extra notice and oversight.

A little front-loading — gathering values, locating the original will, and confirming whether a bond applies — prevents most of these.

Mini-FAQ

Q: Do I always need probate? No. If the estate is small, or assets passed by survivorship or beneficiary designation, an institution may release them without a certificate. But if any major asset-holder insists, you'll need it.

Q: How long does it take? It varies by court office, the complexity of the estate, and whether anything is contested. Treat any specific timeframe you read as an estimate — confirm current processing times with the court.

Q: Can I do it myself? Some people do. But valuation, the tax, the forms, and bonds are where mistakes get expensive. Many estate trustees ask a lawyer to prepare or review the application.
