Resumes and application forms are not legally binding documents. Including your preferred or chosen name on your resume and on the application form is a common and acceptable practice. Although UBC uses the phrase “preferred name”, for many people this name is not simply a preference: it is the only name they use and it is central to their identity.

There may be moments during the hiring process when you are required to provide your legal name and gender marker, such as during employment background checks that some employers require as a condition of employment.
When hired into a position in Canada, you must provide legal documentation such as identification, and a social insurance card, which display your legal name, and in the case of identification, a gender marker. If you use a gender marker and/or name that is different from your legal documentation, you may want to think about strategies to disclose the discrepancy with a prospective employer. Consider speaking with a coach or advisor to come up with an action plan and practice this conversation so you feel more confident.
In the case of employment references, if your name and/or gender marker has changed since your prior positions for which you are seeking a reference, it might be worthwhile to disclose this to your references so they refer to your correct name (and pronouns) when speaking with your prospective employer.
Your legal obligations may differ in regions outside of Canada. It is best to research your rights and obligations for the jurisdiction you hope to work so that you can make informed decisions.
