These sound like they have been received via aircraft scatter Paul. In
CBCK #2 If you listen to the frequency of the flutter (rather than the
program content) you'll hear it decreasing then increasing again.
There are some clever software progs written by radio amateurs that
exploit this mode by looking at some of the virtual radar servers
online. I'm sure the FM DXing community must be using them too.

The fade ups will come out of nowhere and last 5-15 seconds usually, but
sometimes a bit longer. It happens in the morning, at night.. I haven't
noticed a time when it isn't happening.
I suspect My height, the fact the frequencies are pretty empty here and
that the transmitter sites are close to water make this possible.
Here's a few recent audio clips of CBCK 107.5 and CFLY 98.3
