Adult Name Change (Form 11155) — Notarized Online in Ontario
The official provincial form required to legally change your name in Ontario, sworn before a commissioner over a secure video call.
Legally changing your name in Ontario requires this application to be sworn before a commissioner for taking affidavits before it can be submitted to the Office of the Registrar General. It's a step many applicants overlook until their paperwork is sent back.
Bring the completed Form 11155 to your appointment unsigned. The commissioner verifies your photo ID, witnesses your signature, and completes the commissioner's section — the form is then ready to mail in.
Commissioned in accordance with O. Reg. 431/20. We do not provide legal advice on name-change eligibility or process the application itself — the Ontario Registrar General's office handles that.
