Okay thanks, I appreciate the info, but...
NEXUS is actually the US program run in association with Canada immigration and security for entry into the USA. CANPASS is our own program for entry into Canada.
There are NEXUS machine at YUL for entry into Canada. And there is a NEXUS lane northbound at the I-87/A-15 land crossing. So at the minimum, NEXUS is for bi-directional travel between Canada and US.
Does that mean a passenger flying CDG-YUL would or would not be able to use NEXUS at YUL? And are there any CANPASS machines at Canadian airports for transborder travel INTO the US?
Thanks!
