Were you able to get ok a particular analog TV Station before? Was that analogue TV station your intended market?.

If yes on both answers then you should be complaining to the TV station that you are no longer able to get their DTV signal after the switch. Every engineer expects that unfortuanelly there will be "dark" spots (therefore a few household out of service) on the old coverage area with the new digital but like Bruce said the more people calling their attention the faster they will come up with a solution. It happened in the states 2 years ago when they finally shut analog down, some stations went for low VHF but after the first weeks people complaining they realize they had to do something about it and some went back to UHF.

I also lost CHCH but my antenna system is not the perfect one for VHF anyways. Will see what happens with CTV when they flip on ch 9 HDTV next week.
