Ontario Probate Court Finder

A probate application is filed with the Superior Court of Justice for the county or district where the deceased lived — which for many municipalities means a courthouse in another city. This table covers 70 Ontario municipalities, each verified against the Ministry of the Attorney General’s directory.

How probate venue works in Ontario

Probate (formally, an application for a Certificate of Appointment of Estate Trustee) is handled by the Superior Court of Justice, and the application is generally filed in the county or district where the deceased person lived at the time of death. Many municipalities do not have their own Superior Court location, so the estate is filed at a regional courthouse — often in a different city than you would expect.

Use the finder below to see where an estate for a resident of your municipality is filed, with a link to the official government listing for each courthouse. If the estate you are handling has connections to more than one place, where to file can genuinely be a judgment call — that is worth a conversation before documents go in.

Frequently asked questions

Where do I file probate if the deceased owned property in several places?

The application is generally filed where the deceased lived at death, even if property is located elsewhere. Estates with no Ontario residence, or with connections to several jurisdictions, can be more involved — those are worth professional advice before filing.

What if the municipality is not in the table?

The table covers 70 of Ontario’s largest municipalities. Smaller communities are served by the Superior Court location for their county or district — the official directory linked in each row is the fastest way to confirm.

Do I always need probate?

Not always. Whether probate is required depends on what the estate holds and what the institutions involved will accept — some assets pass outside the estate entirely. It is often worth checking before assuming a full application is needed.

How current is this information?

Each row was verified individually against the Ministry of the Attorney General’s public directory on August 9, 2026. Assignments do change, so confirm with the courthouse before filing.
