I have an upcoming flight from Montreal to Chicago Ohare. I was under the impression that there was a dedicated NEXUS lane through security and that I would not have to take my belt and shoes off.
But this wiki suggests that, for transborder security, this is only the case in Toronto.
https://en.wikivoyage.org/wiki/NEXUS
Specifically, here is what it says:
Express security clearance, similar to TSA Precheck, is available for US-bound flights from Toronto Pearson International Airport (YYZ) Terminal 1. This is a pilot program that may be expanded to other airports in the future if successful.
Is the Wiki correct? If so, it would explain why I had to remove my belt and shoes the last time I did this. I was told that the NEXUS lane was closed. Perhaps it is closed for much longer than I had assumed!
