because most cable packages come in basic, medium and ultimate
and basic is 2-28 (channels like ABC, CBS, NBC, YTV, FOX, Global and other stuff)
medium is 2-32 (which includes eveything before and muchmusic, spike, A&E, and TSN)
and ultimate is 2-? (which includes Teletoon, family(canada's disney), BET, MTV, Dicsovery channel. CNN, BBC, Comedy Network and other stuff)
and obviously the one with more channels costs more...
as for the french thing it's probably because YTV has hosts unlike teletoon so it's harder to have both languages.
