My question is what should I expect and how do I use the nexus line to clear US customs at YYZ these days? Are there kiosks where I scan my Nexus card? I heard they use facial recognition now, how and where do I have my photo taken? Lastly are there Nexus lines to clear customs with an actual agent should these kiosks not work?
Thanks in advance
