Ontario Probate Guide — Every Form, Fee, and Deadline in One Place

You Were Named Estate Trustee. Some Institutions Require a Certificate of Appointment Before Releasing Solely Held Assets. The Ministry of Finance Requires a Separate Estate Information Return Filed Within 180 Calendar Days — With Penalties Starting at $1,000 for Late Filing. And the Estate Administration Tax Calculation Has an Exemption Threshold, a Rounding Rule, and a Deduction Limit That Most Executors Get Wrong on Their First Filing.

Someone you loved has died, and you are now the person responsible for their entire financial life. The bank froze the accounts the day the death was registered — they will not release a cent without a Certificate of Appointment of Estate Trustee, even if you are named in the will and even if you held Power of Attorney the day before. That authority ended at death. The mortgage, property taxes, utilities, and insurance premiums on the house do not pause while you wait for the court to process your application — Ontario's court guidance says applications are typically processed within 15 business days, although missing documents or issues requiring a judge can extend the wait. You are carrying the estate's costs out of your own pocket, and the beneficiaries are asking when they will see their share.

You searched for help. Ontario.ca publishes the court forms and separate instructions for standard and small-estate applications. You still have to match your circumstances to the right process and supporting documents and check the filing requirements. The Superior Court accepts probate applications by email, regular mail, or in person. If you file by email, original documents such as the will and codicils must still be filed in paper format by mail, courier, or in person. Law firm websites explain the complexity in careful detail, then quote $3,000 to $5,000 for standard probate representation. ClearEstate starts at $4,948. Reddit has answers, but the top comment applied Nova Scotia's tiered probate fee structure to an Ontario question — Ontario's Estate Administration Tax works completely differently.

Here is what nobody connects for you: Ontario uses its own terminology — "Estate Trustee" instead of executor, "Certificate of Appointment" instead of Grant of Probate — and Ontario court forms use these terms. The estate is overseen by two separate bodies operating on independent timelines: the Superior Court of Justice issues the Certificate, but the Ministry of Finance independently assesses the estate's value through the mandatory Estate Information Return filed with the Ministry. Receiving the Certificate is not the finish line — the Ministry can assess or reassess Estate Administration Tax within four years after the Certificate date, or at any time if required information was not filed or a misrepresentation is established. The Estate Administration Tax calculation has a $50,000 exemption, a rounding-up rule, and a deduction limit that allows only real estate encumbrances — not credit card debt, not funeral costs, not income tax owing. And since April 2021, estates valued at $150,000 or less can use the simplified Small Estate Certificate, but it has its own 30-day notice period that catches applicants off guard when they discover they cannot file until the waiting period expires.

The Ontario Probate Process Guide is a Court-Ready Filing System for the complete Ontario probate process — from the initial question of whether a Certificate of Appointment is even required through the CRA clearance certificate and final distribution. Not a generic Canadian probate overview that confuses Nova Scotia's tiered fee structure with Ontario's flat-rate tax. Not a law textbook. A 13-chapter, Ontario-specific manual built around the current Estates Act, the Estate Administration Tax Act, Rule 74 and Rule 74.1 of the Rules of Civil Procedure, the Succession Law Reform Act, and the Trustee Act — to help you avoid common errors that can lead the court to return an application.

What's Inside the Court-Ready Filing System

A 13-chapter guide, a standalone Probate Quick-Start Checklist, and 7 printable reference tools — covering every stage from the probate decision through final distribution, built specifically for Ontario's Superior Court of Justice as the forms and rules exist right now:

Chapter 1: Understanding Ontario's Probate System

Ontario's court process is an application for a Certificate of Appointment of Estate Trustee; "probate" is the common shorthand. This chapter explains the terminology, the critical distinction between the Superior Court of Justice (issues the Certificate) and the Ministry of Finance (assesses Estate Administration Tax based on the Estate Information Return), and why Power of Attorney authority ended the instant the person died — even if you are also named Estate Trustee in the will. The key legislation: the Estates Act, the Succession Law Reform Act, the Estate Administration Tax Act, Rules 74 and 74.1, and the Trustee Act.

Chapter 2: Immediate Actions — Days 1 to 7

The Funeral Director's Proof of Death versus the Official Ontario Death Certificate from ServiceOntario ($15 regular, $45 premium expedited — regular processing is 15 business days plus Canada Post delivery). Securing the property, redirecting mail, locating the original will (check the home, the lawyer's office, the bank safe deposit box, and the Superior Court of Justice). Notifying Service Canada to cancel OAS and CPP payments before overpayments accumulate. The CPP Death Benefit application — up to $5,000; the executor should apply within 60 days, and if the executor has not applied, other eligible people may receive the benefit in priority order.

Chapter 3: Do You Actually Need a Certificate of Appointment?

Not every Ontario estate needs a trip to court — and the Estate Administration Tax alone can run into thousands of dollars for larger estates. The decision framework: joint tenancy property passes automatically with just a death certificate; RRSPs, TFSAs, and life insurance with named beneficiaries bypass the estate entirely; banks will often release solely-held accounts under approximately $40,000 with a personal indemnity agreement signed by all beneficiaries. The First Dealings Exemption for certain Land Titles Conversion Qualified (LTCQ) properties where the transaction is the first dealing after Ministry conversion to Land Titles — this can bypass the Certificate requirement for that property transfer. The decision checklist that helps you determine whether you need to apply.

Chapter 4: Standard vs. Small Estate — Which Process Applies?

Since April 1, 2021, estates valued at $150,000 or less can use the optional simplified Small Estate Certificate under Rule 74.1 — a simpler form (74.1A), no administration bond usually required, and faster processing. The standard application under Rule 74 (Form 74A) is also available for estates of any value. The small-estate process has a mandatory 30-day notice period: you must serve a copy of the application to all beneficiaries at least 30 days before filing. The side-by-side comparison so you can choose the process that fits before preparing a single form.

Chapter 5: Calculating the Estate Administration Tax

The exact math that determines whether your application is accepted. First $50,000 of estate value: $0. Every $1,000 above $50,000 (rounded up): $15. Estates at $50,000 or less pay nothing. The critical deduction rule: you can subtract real estate encumbrances (mortgages, registered liens) from the property value, but you cannot deduct credit card balances, personal loans, funeral costs, or income tax owing. A worked example showing how the calculation works for a $300,000 home with a $100,000 mortgage plus $39,250 in bank accounts. The EAT quick reference table from $50,000 to $1,000,000. And the rounding-up rule that catches people who calculate to the exact dollar.

Chapter 6: Preparing Your Court Application

The chapter that does not exist in any free resource. Which forms you need depends on whether you use the regular or small-estate process, whether there is a will, whether the deceased was an Ontario resident, and whether any beneficiary is a minor or incapable person. Form 74A for a regular application versus Form 74.1A for a small-estate application, plus Form 74D, 74E, or 74F for will evidence and Form 74G for a required renunciation or consent. What the court checks on every page, the name-matching requirement between the death certificate and the will, and the errors that can cause the registry to return an application.

Chapter 7: Filing Your Application

Ontario's probate filing process through the Superior Court of Justice. Applications can be filed by email, regular mail, or in person. With email filing, original documents such as the will and codicils must still be filed in paper format by mail, courier, or in person, and the EAT must be paid when you file. Which court location to file with, what to include, the current court guidance that applications are typically processed within 15 business days (longer if documents are missing or a judge must decide an issue), and what to do when you receive the Certificate — including how many certified copies to request and why you need more than you think.

Chapter 8: After the Certificate — Post-Grant Duties

The Certificate is in your hands, but the most consequential deadlines are just starting. The Estate Information Return (EIR) must be filed with the Ministry of Finance within 180 calendar days of the Certificate date — penalties for late filing or false or misleading statements may include a fine of at least $1,000, up to twice the tax payable, imprisonment for up to two years, or both. This chapter covers the Ministry's filing options, what it requires in the EIR, how the Ministry can assess or reassess Estate Administration Tax within four years after the Certificate date or at any time if required information was not filed or a misrepresentation is established, and the estate-closing obligations: creditor notices, debt settlement priority, the terminal T1 tax return, deemed disposition rules, and the CRA Clearance Certificate (Form TX21, requested using Form TX19).

Chapter 9: Edge Cases and Special Situations

The First Dealings Exemption explained in full — how LTCQ real estate status can bypass the Certificate requirement for qualifying property transfers, while the property's value still counts toward Estate Administration Tax. Administration bonds for intestate estates and non-resident Estate Trustees (usually double the estate value unless a judge orders otherwise, with sureties). Multiple wills strategy for Ontario private company shares. Lost or destroyed wills and the separate court process required. Foreign assets and multi-jurisdictional estates. Minor and incapable beneficiaries — when you must involve the Office of the Children's Lawyer or the Public Guardian and Trustee.

Chapter 10: Executor Compensation

Ontario's unofficial 5% tariff — the longstanding convention that Estate Trustees may claim approximately 2.5% on capital receipts and 2.5% on capital disbursements. When compensation requires a passing of accounts versus a consent from all beneficiaries. How to calculate and document fair compensation that will withstand scrutiny if any beneficiary objects.

Chapters 11-13: Distribution, Timeline, and Key Contacts

The final distribution process — why you should obtain the CRA Clearance Certificate (Form TX21, requested using Form TX19) before final distribution, and how to retain enough assets to cover potential CRA liabilities if you distribute earlier. The complete timeline from death through estate closing on one page. And every contact: the Superior Court of Justice, ServiceOntario, the Ministry of Finance, the CRA, Service Canada, the Office of the Children's Lawyer, and the Public Guardian and Trustee.

Who This Guide Is For

• The newly named Estate Trustee who has never filed a court document and needs Ontario's unique forms and terminology — Certificate of Appointment, Estate Trustee, Form 74A versus 74.1A — translated into plain language with the filing requirements, the form selection logic, and the common rejection triggers explained step by step
• The surviving spouse who needs to know whether joint tenancy, named beneficiaries, and the bank's indemnity agreement threshold mean the estate can be settled without a Certificate — and what still must be done even if the court process is not required
• The DIY executor on a budget who knows that law firms charge $3,000 to $5,000 for standard probate and ClearEstate charges $4,948 or more — and needs a guide that replaces hourly consultations for routine procedural questions, while clearly identifying the complications that genuinely require professional help
• The out-of-province Estate Trustee managing an Ontario estate from British Columbia, Alberta, or another province — who needs to know which steps can be handled remotely by email with the Superior Court and which require original documents filed in paper format, plus the administration bond requirement for non-resident applicants
• The executor under family pressure who needs a clear timeline to show impatient beneficiaries that court applications are typically processed within 15 business days (and can take longer if incomplete or sent to a judge), while the 180-calendar-day EIR deadline and CRA clearance processing time are separate parts of the process — not evidence of delay or negligence

Why Free Resources Will Not Get You Through This

The information exists. It is scattered across Ontario.ca, the Ontario Court Forms site, the Ministry of Finance, ServiceOntario, Service Canada, and the CRA. Here is what you encounter when you try to assemble the process from free sources alone:

• Ontario.ca publishes the forms and basic filing steps. Forms 74A, 74.1A, 74D, 74E, 74F, and 74G are available from ontariocourtforms.on.ca. You still need to match the requirements to your circumstances, gather the supporting documents, and follow the court's email or paper-filing process. The guide organizes those tasks into a sequence and points out common errors such as name mismatches, incorrect EAT calculations, and missing affidavits.
• The Ministry of Finance publishes the EIR deadline and filing options. You must file the Estate Information Return within 180 calendar days of the Certificate date; the Ministry accepts it online, by mail, courier, in person, or by fax. You still need to gather asset values and supporting records for your estate. The guide brings the requirement and filing steps together with the rest of the probate process.
• Law firm blogs explain the complexity to justify retainer fees. Probate lawyers publish clear, helpful articles answering specific questions — the EAT formula, the small estate threshold, the First Dealings Exemption. Each article concludes with a call to book a consultation at $300 to $500 per hour, with full representation running $3,000 to $5,000 or more. For contested estates, that advice is appropriate. For uncontested estates with a clear will and cooperative beneficiaries, the same answers cost a fraction of a legal retainer.
• Reddit applies the wrong province's rules. The most common error on Canadian personal finance forums is applying another province's probate fee structure to an Ontario question. Nova Scotia uses a tiered structure with a base-plus-overage calculation. British Columbia charges no probate fee on estates valued at $25,000 or less, then $6 for each $1,000 or part thereof over $25,000 up to $50,000 and $14 for each $1,000 or part thereof over $50,000. Ontario has a $50,000 exemption and a $15-per-$1,000 flat rate above that — plus the unique deduction rule that allows real estate encumbrances but nothing else. Wrong-province advice applied to an Ontario estate means either overpaying for unnecessary legal help, or missing Ontario-specific requirements like the 180-calendar-day EIR, the Ministry's EIR filing options, and the Small Estate Certificate's 30-day notice period.
• National estate platforms lack Ontario-specific depth. ClearEstate, Willful, and Epilogue provide modern workflows for executors across Canada. They are helpful for general orientation. But they gloss over the specific intersection of Ontario's dual oversight structure (court plus Ministry of Finance), the First Dealings Exemption for LTCQ real estate, the court's email and paper filing requirements, the administration bond requirement for intestate estates and non-resident applicants (usually double the estate value unless a judge orders otherwise), and the unofficial 5% executor compensation tariff. An Ontario executor following national-level guidance risks filing an application that the local court returns for province-specific errors.

Free resources give you forms and filing steps across separate pages, a tax deadline alongside separate filing options, and advice from the wrong province. The Court-Ready Filing System puts Ontario-specific forms, fees, deadlines, and filing steps into one document, in the order the Superior Court of Justice requires them.

— Less Than Thirty Minutes With an Ontario Probate Lawyer

A single consultation with an Ontario probate lawyer costs $300 to $500 per hour. Standard probate representation runs $3,000 to $5,000 for routine estates — and significantly more if complications arise. ClearEstate's assisted service starts at $4,948. For a modest estate, those fees represent a significant portion of what is being passed to the family. This guide costs less than thirty minutes of professional legal time and gives you an Ontario-specific filing system — the application forms and supporting documents used in each process, the Estate Administration Tax calculated with worked examples, statutory deadlines, the Ministry's EIR filing options, and common rejection triggers.
