Welcome to the FAQ website covering document topics in Canada.
I have just applied for a NEXUS card. I have had three surnames that I have used; my maiden name, my (first) married name (which was hyphenated) and my current married name. What documentation is accepted for each of these names? Do I need a marriage certificate for both marriages, a divorce decree and marriage certificate for my current marriage, or is my current passport sufficient?
You should bring everything to the interview to be safe. They may or may not ask but, if they do ask, you want to be prepared to explain everything then and there.
