Galaxy 10R carries all the major US networks, minus NBC of course, that's where I would look first. Unfortunately, I don't know what kind of a look angle you would have in canada, since I happen to be on the west coast USA.

C-band won't work on the 39 inch dishes since you need a bigger reflector surface to take in the signals due to the fact that they use a smaller wattage than Ku-band. C-band requires at least an 8 foot dish to get a decent signal from C-band.
