How to fill the Ontario application to change a child's name — and autofill it with my-id.ca
Change a child's name in Ontario — then update their records from one profile
A child's legal name change is one application that triggers updates to their health card, school records, and more. This guide is an example of using my-id.ca to fill the application and breeze through the follow-on updates.
Official form and source
Start from the official ServiceOntario source and always use the current version — form numbers and links can change:
- Service page: Change your name — ontario.ca
- Form (Central Forms Repository): Application to Change a Child's Name — 007-11156
What this form is about
The application asks ServiceOntario to register a child's new legal name. It needs the child's identity details, the new name, the applicant's relationship, and proof of Ontario residency.
Before you start: what to gather
- The child's current full legal name, date of birth, and place of birth.
- The requested new name.
- The applicant's details and relationship to the child.
- Ontario residency information and the current address.
Consent or notice rules may apply — confirm the current requirements on ontario.ca.
How my-id.ca makes it faster
- Store the family once. Save the child's and applicant's details in my-id.ca.
- Autofill the application. Use the my-id.ca Chrome extension on a web form, or fill a PDF from your saved profile inside my-id.ca.
- Submit it yourself through ServiceOntario.
- Cascade the change. Update the child's new name in my-id.ca, then autofill the health card and other record updates.
Why do it in my-id.ca
The point of a name change is consistency across a child's records. my-id.ca keeps one source of truth — stored in Canada, with AI on its own servers — so every form after the change reflects the new name without repeated typing.
