Agreed - that should not be a factor in your decision - nice if it happens, but don't bank on it.
I would recommend taling to Adam Penner at harvsair.com in Manitoba - he has a feel for the Canadian industry and runs a good school as well.
Bush flying wouldn't necessarily require an M/E and IR, but you could look at a float plane rating - after 500 hours that might get you into firefighting.
