Key takeaways
  • Your application package follows a set checklist that starts with Form 74A and includes the original will, proof of death and any renunciations or consents.
  • Every beneficiary, including charities and contingent beneficiaries, must be served before you file, with extra steps for minors, unborn or unascertained persons and incapable adults.
  • You can file by email, but original wills, codicils, bonds and certified copies must still be delivered on paper.

If you are named as executor in a will, you will often need a court document that confirms your authority before banks or land registries will deal with you. In Ontario, the estate normally has to be probated when the deceased owned real property or assets held by a financial institution, and an estate worth $150,000 or less can apply for a Small Estate Certificate, so it is worth checking whether the institution requires a certificate of appointment or a small estate certificate. This article walks through the application step by step.

The process is mostly paperwork, but the order matters: gather documents, sign them properly, serve the right people, then file. Forms were renumbered in 2022, so always download the current versions from ontariocourtforms.on.ca rather than using older copies.

Do you need probate at all?

If the deceased owned real property or assets held by a financial institution, the estate normally has to be probated, and it is wise to ask each institution whether it requires a certificate of appointment or a small estate certificate. Probate is not always required, though. Assets held jointly or with a designated beneficiary, such as an insurance policy or a joint bank account, pass according to how they are owned or designated.

The document checklist

The probate checklist under Rule 74.04 and Ontario guidance includes the following items.

The application and affidavits must be signed before a Commissioner for taking affidavits, who must also sign them. The original will and any codicils must be attached as an exhibit to an affidavit.

Co-named executors who are not applying

Rule 74.04(1) requires renunciations from people who are entitled to act but are not joining the application. A renunciation is made on Form 74G (Part A), while a consent to someone else's appointment is made on Form 74G (Part B). An executor who renounces loses all rights as executor, and the estate then passes as though that person had never been named. Nobody has to act just because they are named, so a conversation with co-executors early on can save delays.

Who must be served before you file

The application must be served on every beneficiary, including charities and contingent beneficiaries. Ontario guidance says this is done before filing with the court, by email or by mail or courier to each person's last known contact details. Some beneficiaries need special handling.

BeneficiaryWho must also be served
A minorThe minor's parent or guardian, and the Children's Lawyer
Unborn or unascertained personsThe Office of the Children's Lawyer should also be served
A mentally incapable adultThe guardian, the attorney, or the Public Guardian and Trustee, depending on who has authority

When the Children's Lawyer or the Public Guardian and Trustee is served and there is a will, a statement of the estimated value of the person's interest must be included.

Where and how to file, and what it costs

File in the county or district where the deceased had a fixed place of abode. If the deceased had no fixed place of abode in Ontario, file where the property is located.

Probate applications may be filed with the Superior Court of Justice by email, but original wills, codicils, administration bonds and certified copies must still be filed on paper, in person, by mail or by courier. Estate administration tax payments must also be made in person or sent by mail or courier to the court office.

No tax is payable if the estate is worth $50,000 or less, and above that the tax is $15 for each $1,000 or part of $1,000 over $50,000 for applications made on or after January 1, 2020. The tax is paid as a deposit when you file, and the estate pays it, not you personally. If the deposit is based on an estimated value, you must undertake to file a sworn statement of the actual value and pay any additional tax within six months.

What happens next

Applications are typically processed within 15 business days. The registrar may ask for further information, and must refer applications that raise issues to a judge. A refused application receives a Registrar's Notice on Form 74O stating the reason, and missing documents can be supplied when court staff ask for them.

An approved certificate is issued electronically and sent by email unless you requested a paper certificate.

Frequently asked questions

Can I file my probate application by email in Ontario?

Yes, probate applications may be filed with the Superior Court of Justice by email. However, the original will, codicils, administration bonds and certified copies must still be filed on paper.

Do I serve beneficiaries before or after filing?

Ontario guidance says service on beneficiaries is done before filing with the court. You prove it with Form 74B, or a lawyer's certificate of service on Form 74B.1.

What if another named executor does not want to act?

That person can renounce on Form 74G (Part A). After renouncing, they lose all rights as executor.

What if the court refuses my application?

You will receive a Registrar's Notice on Form 74O stating the reason. Missing documents can be supplied when court staff ask for them.
