Rogers seems to be in favour of keeping OTA
Shaw has made a huge investment in converting all of Global to digital as they promised they would - wouldn't make any sense that they'd be against it.
CBC and Bell are dead set against OTA.. In fact CBC's CRTC presentation was that not only would the end OTA, they wanted to maintain must carry status on cable, and get this, a surcharge on all cable bills that would go directly to them - good luck with that Hubert Lacroix!!

Many of the smaller/regional broadcasters like TVO and CHCH have too few transmitters to amount to any significant savings since the towers/ATSC transmitters are already in place.

OTOH, Bell has a network that resembles the old CBC analog network - transmitters in places in Wawa, ON, Flin Flon, MB, places that CBC has already abandoned and Shaw/Rogers (their networks' previous owners to be fair) never went. Makes sense in some of those places to level the playing field, but of course they ask for the whole enchilada.
