From
www.cpb.gov re: AIR entry:
All Canadian Citizens entering the United States by AIR are required to present a valid passport,
or a NEXUS card when departing from Canada. Please be advised that if arriving in the United States on a flight
not pre-cleared by the CBP in Canada, Global entry kiosks cannot be used by passengers only holding a NEXUS card, and the
regular inspection lanes have to be used.
Travel by Air: All Canadian Citizens entering the United States (U.S.) by AIR are required to present a valid passport. However,
if entering the U.S., as a participant in the NEXUS program from a designated CBP Pre-Clearance location, a NEXUS card may be used in lieu of a passport.
The NEXUS card will be recognized by the Global Entry kiosks in Canada Preclearance locations only. When using the Global Entry kiosks in Canada Preclearance locations you can use your passport, U.S. Lawful Permanent Resident card
or NEXUS card. You cannot use your NEXUS card at Global Entry
kiosks outside of Canadian Preclearance locations.
From speaking to CPB: you
can fly into the US with Nexus only. If the flight is precleared, you can use the Global Entry kiosk. If the flight is not precleared, you have to go through regular inspection lanes. Not all employees however may be aware of this, and this seems to be where it gets iffy (where employees ask for passport instead of Nexus card). They say to check with your airline/airport.
NEXUS (US Pre-Clearance) is offered at the following airports:
- Halifax Robert L. Stanfield International Airport
- Montréal Pierre Elliott Trudeau International Airport
- Ottawa Macdonald-Cartier International Airport
- Toronto Pearson International Airport
- Winnipeg James Armstrong Richardson International Airport
- Calgary International Airport
- Edmonton International Airport
- Vancouver International Airport
Re: LAND entry:
- A Nexus card can be used at all ports of entry in lieu of a passport. If the port has a Nexus lane, then obviously you can use that. If they don't, you just show the border guard you Nexus card like you would your passport.
