As long as your NEXUS card shows Canadian or US citizenship, you can use it at the Air Canada check-in counter at SFO as well as at the NEXUS machines at YVR. You would then proceed to the domestic wing at YVR. At YVR, look for CATSA's Priority clearance line - they will accept your NEXUS card there too.
