Ontario Name Change Process

Couples don’t have to legally change a last name (surname). But if they choose, they can understand how to do so through ServiceOntario and determine the differences between assuming a married name and legally changing a name after marriage.

​

If you wish to change your last name after marriage in Ontario, decide which of the two options for changing your last name work best for you. You can assume a new name, or you can opt for changing your name legally on your birth certificate.

​

Here are the two options as of July 21, 2021. See my blog post for the details!
