I just flew back from Canada. As required, I filed a Canadian flight
plan and contacted US Customs (I cleared Customs at Sault St. Marie,
Michigan). No one said anything about me having to close my flight plan
with USA flight service (and come to think of it, I never have closed
the other times I've landed). There is no flight service frequency that
I could find at Sault St Marie. Anyway, after clearing customs, I
called FSS. My flight plan had been closed! Does US Customs call US FSS
and close my flight plan? What happens if I don't show up? Will I get
Canadian search and rescue? No one at FSS seems to know. The FSS guy
seemed to think I was responsible for closing my flight plan, yet I've
never done it before either.

Anyone know how this is working?

As far as I'm aware, you have the usual responsibility to close your VFR
flight plan when you fly from Canada to the US. In general, though, if you
fail to close a flight plan, then the first step in the SAR response will be
to telephone the airport where you landed--the tower (if there is one), or
else the FBO (if any), or conceivably a Customs office (if your flight plan
was international, SAR can deduce that you'd be stopping in there). So
perhaps that's what has been happening after your cross-border trips.
