If I can get an appointment at YYZ, how easy/difficult is it to get from the Int'l arrival terminal to the Nexus area and back to the Transborder terminal? I'm planning a trip to Asia, and am connecting on my way back through YYZ. I have a 4 hour layover before my flight to ORD, and supposedly the Nexus office is open until 8:00pm, but it's in the Departure terminal. Assuming my application goes through and I can get an appointment for that date and time (two big IFs), do you think I could make it the following work?

- Flight from Tokyo (HND) to YYZ arrives at 4:40pm (Air Canada)
- Clear Canadian customs - gently explain that I'll be "in Canada" just to complete a Nexus application and then go back to the US.
- Make it to the Departure terminal.
- Schedule Nexus interview at, say 6:00pm.
- Make it back through the Transborder terminal - Declare my Asia trip items to US customs (I don't expect to be above $800).
- Board flight to ORD at 8:30pm.

Might this work? I'd like to be able to minimize my trips.

BTW, my trip isn't until the end of March.
