Probate is filed where the deceased lived, not where the property is. For someone whose home was in Kingston, that means the Superior Court of Justice for Frontenac — the Kingston (Frontenac County) Courthouse.
The application is for a Certificate of Appointment of Estate Trustee. If the deceased was not living in Ontario at death, it is filed where they owned Ontario property instead.
Kingston is a single-tier municipality — it has no county council above it, and court jurisdiction in Ontario follows those boundaries rather than city limits — which is why the answer above is about Frontenac, not about Kingston on its own.
You are not alone in this. Residents of Central Frontenac, Frontenac Islands, North Frontenac and South Frontenac file at the same court, because all of them sit inside Frontenac. There are 5 municipalities in Frontenac in total.
The Kingston (Frontenac County) Courthouse handles Superior Court civil filings, Small Claims Court, enforcement of orders, a Crown Attorney's office and the Victim/Witness Assistance Program. It is in the city itself, so there is no travel out of town for a filing or an appearance.
The Kingston (Frontenac County) Courthouse is not a family-only building. Per the Ministry of the Attorney General's court directory it handles civil claims, criminal matters, a Crown Attorney's office, an enforcement office, Small Claims Court and a Victim/Witness Assistance Programme office. That matters practically: the counter you deal with, the filing hours and the other business going through the same registry are shared with those other streams. Probate applications for someone who lived here are filed at this Superior Court location.
Kingston has its own courthouse, so there is no travel built into your file. That is not true everywhere in Ontario — many municipalities are served by a courthouse in the county seat — and it is worth knowing which situation you are in before you plan around hearing dates.

Kingston had a 2021 census population of 132,485 across 57,836 occupied private dwellings, an average household of 2.29.
For most estates here the house is the estate. Ontario's Estate Administration Tax is charged on the value of the estate, and a home in Kingston is usually the largest asset in it — which is why the valuation date figure, not the price the family remembers paying, is what the application turns on. Title is registered through the Frontenac Land Registry Office (LRO #13).
Of 63,095 private dwellings in Kingston, 5,259 (8.3%) had no usual resident at the census. A property standing empty through an estate administration raises its own questions — insurance on a vacant home, and who is responsible for it while probate is pending.
Population and dwelling counts: Statistics Canada, 2021 Census of Population (source), retrieved 2026-07-28. Averages are computed from those counts.
The first question is usually whether probate is needed at all. It is not automatic. What forces it is what the estate holds and what the institutions holding those assets insist on — a bank or the land registry asking for a Certificate of Appointment before they will deal with you. Assets held jointly with right of survivorship, or with a named beneficiary, may pass outside the estate entirely.
Where an application is needed, it goes to the Superior Court of Justice for Frontenac — the courthouse in the city itself. The estate trustee is the person who signs it, and who becomes personally responsible for getting the administration right.
That personal responsibility is the part most executors underestimate. An estate trustee who distributes before debts and taxes are settled can end up paying the difference themselves. A clearance certificate from the Canada Revenue Agency exists precisely to protect against that, and skipping it to move faster is a false economy.
If there is no will, someone still has to be appointed. Entitlement to be appointed is governed by the Estates Act; who actually inherits is governed by the Succession Law Reform Act. They are two different questions with two different answers, and conflating them is the most common mistake we see from Kingston families trying to sort an intestacy themselves.
Estate Administration Tax is set by the province and is the same everywhere in Ontario — it does not vary by city.
| Value of the estate | Tax |
|---|---|
| First $50,000 | Nil |
| Above $50,000 | $15 per $1,000 (or part thereof) |
| Example — a $240,000 estate | $2,850 |

With the Superior Court of Justice for Frontenac — Kingston (Frontenac County) Courthouse. The rule is that probate is filed where the deceased lived at the time of death, not where their property is located.
Not always. It depends on what the estate holds and what the institutions holding those assets require. Jointly held property passing by survivorship and assets with a named beneficiary may pass outside the estate.
Nil on the first $50,000 of estate value, then $15 for every $1,000 (or part) above that. On a $240,000 estate the tax is $2,850. It is the same across Ontario.
Someone applies to be appointed estate trustee without a will. Entitlement to be appointed is governed by the Estates Act; who inherits is governed by the Succession Law Reform Act. They are two different questions.
Yes. We work online across Ontario, and the filing venue is determined by where the deceased lived, not by where you are.
