Can an executor refuse or quit after being named in a will in Ontario?

Yes. Being named executor in a will does not obligate you to accept the role. Before you take any steps to administer the estate — opening mail, dealing with banks, or paying bills — you can formally renounce the appointment. Renunciation is done in writing and filed with the court. Once renounced, you generally cannot change your mind.

The situation is more complicated if you have already begun acting as executor. Taking steps that clearly signal you have accepted the role — known as "intermeddling" — can make it harder to later withdraw. Courts have found that actions like accessing accounts or dealing with creditors can constitute acceptance, even without an explicit statement.

If a co-executor renounces, the remaining co-executor(s) can usually continue alone. If the sole executor renounces and there is no alternate named in the will, the court may appoint an administrator. The estate may also need to apply for a Certificate of Appointment of Estate Trustee Without a Will, depending on the circumstances.
