About this document

What is an application to change an adult’s name?

Important — the change is made through ServiceOntario
A legal change of name is granted by the province through ServiceOntario, which sets the requirements, fees, and any police record check or publication steps. This template supports the sworn statement; it does not itself change your name.
If you only need to confirm a name you already use, a name change affidavit or a resumption of former name declaration may be enough.
