What actually matters when you pick an executor: the job itself, the traits that predict a smooth estate, and when to name a professional instead.

⚖️ This is general information, 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.

An executor, formally an estate trustee, proves your will, gathers and protects your property, pays your debts and taxes, and distributes what is left. The role carries legal duties enforceable by the beneficiaries and, if things go wrong, by a court. Most people default to the eldest child or a spouse without asking whether that person wants the job, has time for it, or gets along with the other beneficiaries. This guide sets out what the role involves, the traits worth weighing above age or birth order, and when naming more than one executor, or a professional, makes more sense than picking a favourite.


What the job actually involves

Locating the will and arranging for it to be proved, sometimes through a Certificate of Appointment of Estate Trustee, sometimes without one. Securing and valuing the property. Paying debts, funeral costs and the deceased's final taxes before anyone receives a distribution. Distributing what remains to the beneficiaries named in the will and accounting for every step along the way.

The role is a fiduciary one: an estate trustee must act in the beneficiaries' interests, not their own, and can be held personally liable for mistakes, delay or favouritism. Even a straightforward estate commonly takes a year or more to finish, between notice periods, tax filings, and the time it takes to sell or transfer property.

Traits that matter more than birth order

Naming more than one executor

Joint executors generally must act together, which protects against one of them acting alone but can deadlock the estate if they disagree. Before naming co-executors, weigh whether the two people actually work well together, not just whether including both seems fair.

A will can also split responsibility, naming one estate trustee for a business interest and another for everything else, but that division needs careful drafting so authority doesn't overlap or leave a gap for either role.

When to name a professional or the Public Guardian and Trustee

If no suitable person is available or willing, a trust company, or as a last resort the Public Guardian and Trustee, can act as estate trustee. A professional charges compensation from the estate under the same customary tariff a lay executor could also claim.

This is worth considering for a complex estate, an estate likely to see conflict among beneficiaries, or when every plausible candidate is also a major beneficiary with something to gain from a particular outcome.
