Change a child's sex designation on an Ontario birth registration — then update their records

Changing the sex designation on a child's birth registration is one application that can cascade to their birth certificate and health card. 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 a Child — 11327

What this form is about

The application asks ServiceOntario to update the sex designation on a child's Ontario birth registration to male (M), female (F) or non-binary (X). The process depends on the child's age, and consent or supporting declarations may apply.

Before you start: what to gather

• The child's current registration details: full name, date of birth, and place of birth.
• The requested designation (M, F or X).
• The applicant's details and relationship to the child.
• Any supporting documents, consents, or declarations (confirm on ontario.ca).

How hivi makes it faster

1. Store the family once. Save the child's and applicant's 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 the child's health card update from the same profile.

Why do it in hivi

An identity change only matters 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.
