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 hivi 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 hivi makes it faster

1. Store your details once. Save your registration details in hivi.
2. Autofill the application. Use the hivi Chrome extension on a web form, or fill a PDF from your saved profile inside hivi.
3. Submit it yourself through ServiceOntario.
4. 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 hivi

An identity change only works when it reaches every record. hivi keeps one source of truth — stored in Canada, with self-hosted AI — so each follow-on form reflects the change without repeated typing.
