What proof of identity do I have to show in order to obtain my Ontario driver's licence?

If you are Canadian citizen, you must show your passport, a Canadian Citizenship Card or Certificate of Canadian Citizenship (if issued prior to February 1, 2012), a Secure Certificate of Indian Status Card or an Ontario Photo Card. If you have none of these, two documents combined, for example your birth certificate and a marriage certificate, may be acceptable: check the rules before applying.
