According to the digital migration portion of their site, everything should be digital only by now all over Ontario.
Here in Windsor, I have no idea if that message ever existed. All I've seen since mid-February, when I finally got a line installed near the computer, was a set of colour bars on analog channels 3, 14, 58 & 70. It probably did, but never was connected when it happened.
This is interesting though. It could be the reason for the 2 month delay for the addition of more HD versions for CNN, HLN and possibly others. They may be giving time for the messages to stay up on those systems that just had their analog service turned off.
