Although I was always hoping that since they are both CHUM stations, that CityHD would multicast for A-Channel in SD, and then eventually when A-Channel HD goes live, they can multicast CityHD.

I know multicast can hurt the PQ a bit, however once CKVR-DT begins to broadcast, it will lead to thsoe in Central Ontario to finally be able to get an ATSC signal, so it would make sense to have both going. Even today, would make sense being that A-Channel airs a lot of worthy shows, most notibly Leno.
