What happens if the sole executor dies before the estate is fully distributed in Ontario?

If the sole executor dies during the administration of an estate and the original testator's estate is not yet fully distributed, the administration must continue but there is no one left with authority to act. In this situation, someone — usually the deceased executor's own estate trustee or a beneficiary — must apply to the Ontario Superior Court of Justice for a new Certificate of Appointment of Estate Trustee to continue the work.

The will may have named an alternate executor for exactly this reason. If an alternate was named, that person can step in with fewer court formalities, though they will still need to obtain their own Certificate of Appointment.

This situation underlines the importance of naming at least one alternate executor in your will, and of periodically reviewing your estate documents to ensure your chosen executor is still alive, willing, and capable. If no one applies to administer the estate, it can stall indefinitely, causing hardship for beneficiaries.
