1. Assume a last name due to marriage
You can assume your spouse’s last name after marriage with government documents such as:
Ontario Photo Card
enhanced driver’s licence
There is no cost to assume your spouse’s last name on the above documents. When you assume a spouse’s last name after marriage, it does not change the name on your Ontario birth registration (and birth certificate). You should change all your identification documents to reflect the new last name.
To change your last name on these documents, visit a ServiceOntario centre with your:
this is not the “Record of Solemnization of Marriage” given to you by the person who performed your marriage
you must apply for a certificate as one is not issued to you automatically
current photo health card (if you do not have a photo health card, you must bring 3 original documents to prove you are a Canadian citizen and Ontario resident)
driver’s licence, enhanced driver’s licence or Ontario Photo Card
