(1.1) Except as prescribed, no person shall make use of or divulge a
radio-based telephone communication


(a) if the originator of the communication or the person intended by
the originator of the communication to receive it was in Canada when
the communication was made;

since when does Canadian law have authority over U.S. law and U.S. citizens?

Several U.S. state laws say that it's completely legal to divulge a recording
of a telephone conversation as long as the person doing the divulging was one
of the parties involved in the call. (still illegal for scanner listeners who
are not parties to the call to divulge it).

which is why I'm concerned about the part of Canadian law saying that no person
may divulge it even if the originator of the call is outside of Canada, and
simply calling a person in Canada.
