Certificate of Appointment of Estate Trustee

Ontario retired the old words “letters probate” years ago. The document you’re after is a Certificate of Appointment of Estate Trustee — and the person it names (you, if you’re applying) is the estate trustee, Ontario’s term for executor or administrator.

What the certificate actually does

It’s the court certifying two things at once:

1. This person has authority. Banks, the land registry, investment firms, and buyers of estate property can rely on it. That’s why they ask for it.
2. This will is the one. When there’s a will, the certificate confirms the court accepted it as the last valid will — the certificate literally has the will attached.

It is not a grade on how the estate will be handled, and getting it is not the end of the job — it’s the key that unlocks the job.

The kinds you’ll hear about

Certificate	Plain meaning
Estate trustee with a will	There’s a valid will; the named (or another) person applies
Estate trustee without a will	No will; usually a close family member applies
Small Estate Certificate	The simpler stream for estates of $150,000 or less
Succeeding estate trustee	Replacing a trustee who died or was removed
Estate trustee during litigation	A neutral caretaker while a court fight runs

Most first-time applicants need one of the first three. The others are lawyer territory.

Who can apply

With a will: the executor it names has first claim — and if they’ve died or renounced, an alternate named in the will. The law does not make a named executor live in Ontario. Where you live matters for a different reason: the court asks applicants who live outside the Commonwealth for an insurance-style bond, while a named executor living in Ontario or elsewhere in the Commonwealth doesn’t trigger one. Our software supports applicants who live anywhere in Canada; if you live outside Canada, we point you to a lawyer.

Without a will, the law sets who may apply (usually the closest relatives) and the applicant must live in Ontario — plus a bond usually enters the picture. That application type has enough moving parts that we route people to lawyers for it.

The path to the certificate

The short version: gather the will and asset values → complete the forms (74A stream or 74.1A small-estate stream) → serve everyone entitled to a share → file at the courthouse for where the person lived, paying the Estate Administration Tax → court review → the registrar signs your draft certificate and it becomes the real thing. The long version, with the traps marked, is our step-by-step guide.
