To add, before 9/11 only a drivers licence and birth certificate were needed to cross the US/Canada border. After 9/11 that disappeared unfortunately. Thankfully their “Express security” for a fee became much better with the Nexus program being a combined US/Canada initiative over the older pre 9/11 separate US and Canada programs that were managed independently. It also cost more to enroll.

PS in BC one can get a “enhanced” driver’s licence for crossing the border into the states but it costs more than a Nexus and there is no special lane like Nexus. With the enhanced drivers licence you still need to wait with everyone else in the long line ups.
