Changing Your Name in Ontario: How It Works

In Ontario, legal name changes are made under the Change of Name Act through the Office of the Registrar General (ServiceOntario).

Who can apply

• People who are 16 or older and have lived in Ontario for at least one year before applying.
• Parents can apply for a child, usually with the consent of the other parent.

After marriage or a common-law relationship

• You can often assume your spouse's surname without a legal change.
• For a formal change, you may be able to use an election form, which is simpler than a full application.

The steps

1. Complete the application form.
2. Have it signed in front of a commissioner for taking affidavits or a notary.
3. Include any other documents required, such as a police record check in some cases, then pay the fee and submit it.
4. Receive your change of name certificate.

Update your ID

After the change, update your health card, driver's licence, passport, SIN record, bank accounts and other records.

Who can't change their name

Some applications can be refused, for example a name change made to avoid debts or legal obligations.
