How to Choose an Executor in Ontario: Duties, Liability, and Common Mistakes

Thinking of who to choose as your executor?

Choosing an executor — legally known in Ontario as an estate trustee — is one of the most important decisions you’ll make when creating your will. This person will be responsible for managing your estate, paying your debts and taxes, and distributing your assets to your beneficiaries after you pass away. Yet many Ontarians give this decision far less thought than it deserves.

In this guide, we’ll break down what an estate trustee actually does under Ontario law, the legal liability they take on, and the most common mistakes people make when naming one — so you can make a choice that protects your estate and your loved ones.

What Is an Executor (Estate Trustee) in Ontario?

In your will, you’ll typically name someone as your “executor.” Once that person applies to the Ontario Superior Court of Justice for authority to act, they become known as the estate trustee. If the court issues a Certificate of Appointment of Estate Trustee With a Will (what most people still call “probate”), this document formally confirms their legal authority to deal with banks, the Land Registry Office, and other institutions on the estate’s behalf.

Not every estate requires probate. Assets held in joint tenancy with right of survivorship, or those with a named beneficiary (such as RRSPs, RRIFs, TFSAs, and life insurance), generally pass outside the estate and don’t require a certificate. However, real estate held solely in the deceased’s name, bank accounts, and investment accounts typically do.

This is not an honorary title. It’s a formal legal role under Ontario’s Succession Law Reform Act and Trustee Act, with real duties, deadlines, and personal liability attached.

Key Duties of an Ontario Estate Trustee

Before choosing someone for this role, it helps to understand exactly what you’re asking them to do. Typical duties for an Ontario estate trustee include:

  • Locating and reviewing the will to confirm validity and identify beneficiaries.
  • Applying for a Certificate of Appointment of Estate Trustee from the Superior Court of Justice, if required.
  • Paying the Ontario Estate Administration Tax (EAT), calculated at roughly $15 per $1,000 of estate value over $50,000 (with the first $50,000 exempt), payable from estate funds when the certificate is issued.
  • Filing an Estate Information Return with the Ontario Ministry of Finance within 180 days of receiving the certificate, detailing the estate’s assets and values.
  • Identifying and securing estate assets, including real property, bank accounts, and personal belongings.
  • Notifying beneficiaries and creditors, and placing notices to creditors where appropriate.
  • Filing the deceased’s final T1 tax return and any required estate (T3) returns with the Canada Revenue Agency (CRA).
  • Obtaining a CRA Clearance Certificate before distributing assets, to confirm all taxes owing have been paid.
  • Managing and prudently investing estate assets during the administration period.
  • Keeping detailed accounts of every transaction made on behalf of the estate.
  • Distributing assets to beneficiaries once debts, taxes, and administrative matters are resolved.

Depending on the size and complexity of the estate, this process commonly takes anywhere from several months to well over a year.

Executor Liability in Ontario: What’s at Stake

Many people don’t realize that serving as an estate trustee carries personal legal and financial liability under Ontario law. An estate trustee who fails to fulfill their duties properly — even unintentionally — can be held personally responsible. Common liability risks include:

  • Distributing assets before obtaining a CRA Clearance Certificate. If the estate later owes taxes, the estate trustee can be held personally liable for the shortfall.
  • Missing the 180-day Estate Information Return deadline, or misstating asset values on it, which can trigger penalties, interest, and audits by the Ministry of Finance.
  • Distributing assets too early, before all debts and creditor claims (including the standard limitation periods for claims against an estate) have been addressed.
  • Mismanaging estate assets, such as making imprudent investment decisions or failing to maintain estate property, potentially breaching the “prudent investor” standard under Ontario’s Trustee Act.
  • Breaching fiduciary duty by favouring one beneficiary over another or acting in a conflict of interest.
  • Failing to keep proper accounts, which can lead to disputes, a passing of accounts before the court, or removal as estate trustee.

Because of this exposure, the person you choose should be someone capable of acting carefully, keeping organized records, and seeking professional legal and accounting advice when needed — not simply someone you trust emotionally.

Common Mistakes When Choosing an Executor

1. Choosing Based on Sentiment Alone

Naming your eldest child, a spouse, or a close friend purely out of sentiment or obligation is one of the most common mistakes. Emotional closeness doesn’t always translate into the organizational skill, availability, or objectivity the role requires.

2. Naming Someone Who Lives Outside Ontario or Canada

An out-of-province or non-resident estate trustee can face added complications, including bonding requirements imposed by the court and extra difficulty dealing with Ontario financial institutions and the Land Registry Office. Where possible, consider proximity to the estate’s assets.

3. Not Asking First

Some people name an estate trustee without ever discussing it with them. The role can be time-consuming and stressful, and an unwilling or unprepared estate trustee may decline to act (renounce) or perform poorly under pressure.

4. Choosing Someone With Poor Financial or Organizational Skills

Estate administration in Ontario involves EAT calculations, an Estate Information Return, CRA filings, and detailed financial record-keeping. An estate trustee who struggles with organization or finances in their own life may struggle even more under the added pressure of these obligations.

5. Naming Only One Estate Trustee With No Alternate

If your named estate trustee dies, becomes incapacitated, or is unable or unwilling to serve, and no alternate is named in your will, the court may need to appoint someone under the Estates Act — potentially someone you wouldn’t have chosen yourself.

6. Overlooking Conflicts of Interest

Naming a beneficiary as estate trustee isn’t inherently wrong, but it can create tension, perceived bias, or disputes among other beneficiaries, especially in blended families or estates with unequal distributions.

7. Not Considering a Professional Estate Trustee

For larger, complex, or potentially contentious estates, a professional estate trustee — such as a lawyer or trust company — can provide neutrality, expertise, and continuity that a family member may not be able to offer.

Tips for Choosing the Right Executor

  • Look for organization, integrity, and financial literacy over pure sentimentality.
  • Choose someone willing and able to commit the time the role may require, which can extend well beyond a year for more complex estates.
  • Name at least one alternate estate trustee in case your first choice cannot or will not serve.
  • Have the conversation with your chosen estate trustee before finalizing your will.
  • Consider co-estate-trustees carefully. This can distribute responsibility, but it can also create decision-making conflicts if the co-trustees disagree, since Ontario generally requires unanimous decisions absent a provision in the will stating otherwise.
  • Think about professional support. Even a well-chosen estate trustee can benefit from working alongside an Ontario estate lawyer and accountant to properly navigate the EAT, CRA clearance process, and fiduciary obligations involved.

Final Thoughts

Choosing an executor isn’t just about who you trust the most — it’s about who is best equipped to handle a demanding legal and financial responsibility under Ontario law, often during an already difficult time for your family. The right choice can mean a smoother, faster, and less stressful estate administration process. The wrong choice can lead to delays, disputes, and even personal liability for the person you’ve named.

Taking the time now to think through this decision carefully, and to have an open conversation with your chosen estate trustee, can save your family significant stress down the road.
