How do you apply for probate in Ontario?
You apply to the Superior Court of Justice where the deceased lived, using the Form 74 series: the application, supporting affidavits, the original will and proof of death, served on every beneficiary before filing, with the Estate Administration Tax deposit paid on filing. Estates of $150,000 or less have a simplified path.

What you are actually applying for: the Certificate of Appointment
Probate’s formal name in Ontario is the Certificate of Appointment of Estate Trustee. It is the court’s confirmation of who has authority to administer the estate, and it is the document the land registry and the banks act on. If the estate includes a home registered solely in the deceased’s name, the sale generally cannot close without it, which is why the application is usually the first hard deadline an executor faces.
The probate application, step by step
1. Confirm the right court. Applications are filed with the Superior Court of Justice in the county or district where the deceased lived at death. Durham estates file locally; if the deceased lived outside Ontario, the filing goes where they owned Ontario property.
2. Assemble the package. The core is the Form 74A application, the original will and any codicils, proof of death, and the supporting affidavits that fit the situation, such as an affidavit of execution for the will. The forms were overhauled in January 2022 and have been amended several times since, so always download the current versions from the Ontario court forms site rather than reusing an old set.
3. Value every asset at fair market value.The application states the estate’s value, and the home is usually the biggest line. This number drives the Estate Administration Tax and is later cross-checked against the Estate Information Return, so it needs real support behind it. A documented valuation of the home, prepared before filing, protects the estate trustee twice: it supports the tax filing and it starts the record of pursuing fair market value on the sale.
4. Serve the beneficiaries first, then file.Since the 2022 rule changes there is no separate notice form: the signed application itself is served on every person entitled to share in the estate before it is filed, including the Children’s Lawyer or Public Guardian and Trustee where a beneficiary is a minor or incapable, and proof of service is filed with the application. Applications can be filed by email, by mail or in person.
5. Pay the deposit. Estate Administration Tax is paid as a deposit on filing: nothing on the first $50,000 of estate value, then $15 per $1,000 above it, roughly 1.5 percent. The calculator gives you the estate’s number in seconds. If the application is withdrawn or refused before a certificate issues, the deposit can be refunded.
6. Bond, if there is no will.Where the deceased died without a will, or the applicant is not named in it or lives outside the Commonwealth, the Estates Act requires an administration bond, in principle for double the estate’s value. Courts routinely reduce or dispense with the bond on a supported request, and since 2022 the rules set out the procedure, but it is one more reason intestate applications benefit from a lawyer.
How long probate takes, honestly
Ontario reports that complete, correct applications are typically processed in about 15 business days. The real-world wait from starting the paperwork to holding the certificate commonly runs 2 to 6 months, because preparation, service, requisitions and court volumes all sit outside that 15-day clock. A defective application goes to the back of the queue, which is the strongest practical argument for getting it right the first time.
The small estate shortcut
Estates valued at $150,000 or less can use the Small Estate Certificate, a shorter application with its own form series and, in most cases, no bond. At Durham house prices a solely owned home almost always puts an estate past the threshold, but where the estate is near the line, ask the lawyer before paying for the full process.
This is general information for Ontario, not legal advice. Forms and rules have changed several times since 2022; confirm the current requirements with an estate lawyer or the court before filing.
Questions about applying for probate in Ontario
Where do you file a probate application in Ontario?
With the Superior Court of Justice at the courthouse in the county or district where the deceased lived at death. If the deceased lived outside Ontario, the application is filed where they owned Ontario property. Applications can be filed by email, by mail or in person.
What documents do you need to apply for probate?
The core package is the original will and any codicils, proof of death, the Form 74A application, supporting affidavits, proof that the application was served on every beneficiary before filing, and the Estate Administration Tax deposit. Where there is no will, an administration bond may also be required unless the court dispenses with it.
How much does it cost to apply for probate in Ontario?
Estate Administration Tax is the main cost: nothing on the first $50,000 of estate value, then $15 per $1,000 above it, paid as a deposit when the application is filed. Most estates also pay legal fees; Ontario firms publish flat fees that commonly run in the $1,500 to $3,500 plus HST range for straightforward applications.
Do you need a lawyer to apply for probate?
No, an estate trustee can apply personally. In practice most do use a lawyer, because the forms are technical, service on beneficiaries has to be done correctly before filing, and a defective application goes back in the queue. When a home is the main asset, the cost of a redone application is measured in months of carrying costs.
What happens after the certificate is issued?
The estate trustee can transfer or sell the home and administer the rest of the estate. Within 180 calendar days of the certificate, an Estate Information Return must be filed with the Ministry of Finance, and declared values are checked, so the home's valuation needs to be documented and defensible.
