Assuming/Unassuming a Spouse’s or Partner’s Name

Assuming a name due to a relationship is the most common practice in Canada. A person may choose to assume the use and be recognized by their spouse’s or partner’s surname. This is not a change in legal name, however, is generally accepted. The vast majority of people choose this option.

There is no need for a formal application. You may simply assume your spouse’s/partner’s last name (surname) or a combination of your last name and your spouse’s/partner’s last name (hyphenated surname).

The benefit of not completing a legal name change is that it does not change the name on your birth certificate.

If you wish to use your legal name again, you simply revert back by presenting your birth certificate as proof of your legal name.

Fees

No fee required.

How do I change my name?

Once you are married or in a conjugal relationship (common-law or same-sex marriage), you may apply to change all your identification (health card, drivers licence, passport and banking information etc.) with your marriage certificate. No formal name change is required.
