When you go through security check point at YVR pre clearance, returning to the U.S., a checker will ask you if you are a NEXUS member. If you say you are a Global Entry Member, s/he wants to see your GE card or you will be directed to regular line.

Last few times on Sunday at about 0900 hours, NEXUS lane was not open. Expedited lane was not any faster than regular line. You still have to take everything out. Regular line was shorter.
