Does anyone know the actual reason you're required to file a flight
plan when crossing the boarding between the U.S. and Canada? Does
someone sit down at the end of the year and try to count operations
based on them? They carry NO customs benefit since customs are handled
separately.

Filing a flight plan when crossing an international border is an ICAO
requirement. Of course that doesn't explain why the requirement hasn't been
waived for convenience between the US and Canada, as have many other
requirements that are standard for international stuff. But it does mean
that it would be a question of overriding the default, which may take
unanimity between diverse Canadian departments. Maybe some of them have
access to Google? :-) http://www.invadecanada.us/
