If you change your name and/or address, you must advise SGI of the changes in writing within 15 days, or at your motor licence issuer's office. Any changes to name and/or date of birth must be accompanied by a legal document supporting the change. You can revise your contact information and change your mailing address, physical address or email address through MySGI.
You can also notify SGI of your change of address through the ExpressAddress online service at www.expressaddress.com. This service can also notify several other provincial and municipal government organizations of your address change at the same time.
