As anybody who flies across the US/Canada border knows, the standard
procedure for Canadian customs is to call 1-888-CANPASS before hand, fly
to your airport of entry, and then call 1-888-CANPASS after you arrive.
However, one of the places I commonly fly to, Oshawa Ontario, doesn't
allow that after 16:30 local time. So I'm filling out a form for a
CANPASS ... not sure what they call it - preclearance maybe? Anyway, if
you have this preclearance, you can land at airports of entry as well as
designated non-AoEs, even if customs is officially closed at that time of
day.

I'm hoping somebody whose done this procedure before is reading this,
because I'm having a problem.

The problem is the box on the form labelled "Airport". Am I supposed to
list every airport that I *might* land at in the next 5 years? How do I
know? I've put down all the airports that I've landed at in Canada in
the past (CYOO, CYTZ, CYKZ, CYOW, CYSN). But I also might some day want
to go visit the Canadian Aviation Heritage museum, so should I list
Hamilton? And a few years back they had a fly in at Downsview, so should
I list that in case they have it again? Oh, and it might be cheaper to
land at Rockcliffe instead of Ottawa, so maybe I should list that? You
see, the list just keeps growing and growing.

Get with the program, jeffrey. No one is 'wrong' on Usenet. They are
either 100% totally correct, or they are 'a lying, scum sucking weasel.'
