While I was there, I made a short flight up the St. Lawrence with one of
their instructors. I did all the flying, but I have logged it as dual,
but of course the tail number is a "C-....". The question is, what are
the rules regarding the time logged under a foreign license? Can it be
applied for requirements for advanced ratings on the US side? Or does
time in a "C-...." only apply for Canadian ratings?

As I see it, the FARs do not specifically disqualify time on a foreign
license for the purpose of ratings; however, time you list for such must
be made with an "authorized instructor", which means someone that holds
a CFI here in the US. Check the Canadian equivalent rules/regs for any
specific references.

However, I believe FAR 91.75 (c) states that ratings earned on a foreign
license may be placed on your US license (while not specifying if
testing is necessary; only in reference "additional ratings"). So, if
you earn a rating on a Canadian PPL, it should be applicable over here
as well.

Was all the time logged in Canadian airspace? If so, it may fall under
that jurisdiction exclusively instead, and apply as time earned on a
foreign (student) license (which can be readily applied in the US).
