How to change the sex designation on an adult's Ontario birth registration — and autofill it with my-id.ca
Change an adult's sex designation on an Ontario birth registration — then update your IDs from one profile
Changing the sex designation on a birth registration is one application that can cascade to your birth certificate and other IDs. This guide is an example of using my-id.ca to fill the application and 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: Changing your sex designation on your birth registration and birth certificate — ontario.ca
- Form (Central Forms Repository): Application for a Change of Sex Designation on a Birth Registration of an Adult — 007-11325
What this form is about
The application asks ServiceOntario to update the sex designation on your Ontario birth registration to male (M), female (F) or non-binary (X). There is no fee to change the designation on the registration; certificate fees may apply.
Before you start: what to gather
- Your current registration details: full name, date of birth, and place of birth.
- The requested designation (M, F or X).
- Any supporting documents or declarations the application requires (confirm on ontario.ca).
How my-id.ca makes it faster
- Store your details once. Save your registration 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. Autofill an updated birth certificate request and your health card and driver's licence updates from the same profile.
Why do it in my-id.ca
An identity change only works when it reaches every record. my-id.ca keeps one source of truth — stored in Canada, with self-hosted AI — so each follow-on form reflects the change without repeated typing.
Frequently asked questions
- What does this application ask for?
- Your current birth registration details (name, date of birth, place of birth), the requested sex designation (M, F or X), and any supporting documents or declarations. my-id.ca can store these for autofill.
- Does my-id.ca help update my other IDs afterward?
- Yes. Once your details are stored in my-id.ca, you can autofill the follow-on requests — an updated birth certificate, and changes to your health card and driver's licence.
- Does my-id.ca process the change?
- No. my-id.ca autofills your information; you submit the official application yourself. Confirm the current process and any declarations on ontario.ca.
