Marriage and change of name

After the marriage ceremony, there are three options either spouse may consider in regard to retaining, assuming, or legally changing their last name.

Option 1: Continue to use their last name

Under this course of action, the spouse who wishes to keep their current last name needs to take no action.

Ontario law does not require a spouse to change their last name upon marriage.

Option 2: “Assume” the use of the spouse’s last name

An assumed name is a name which a person uses or adopts.

Upon marriage, a person may choose to “assume” the last name of their spouse and use it.

To have your identification revised most government organizations, credit card firms, etc. will accept a copy of the marriage certificate issued by the Office of the Registrar General as proof of the marriage.

Option 3: Legally change their last name

A legal name is the name by which the person is entitled to be recognized for the purposes of Ontario law.

In this instance, a person will elect the option under the Change of Name Act, complete the appropriate forms and submit them to the Office of the Registrar General
