I think in one recent book, their numbers were around 0.1, which is pathetic (especially when you consider how it did during the glory days of CHUM.) It may be one reason why Bell is thinking of getting rid of it. What a shame for a once iconic station.
By the way, your comment on not being able to get anybody on the phone hit a chord with me. I have run into this problem many, many times in trying to reach a specific radio or TV station. There use to be a receptionist around 7 days a week. Then 5. Now, it's virtually zero.
Instead, you get voice mail telling you to enter the extension you want - but how you're supposed to know the extension with no one telling you is never explained. Then you're told to leave a message, which is never, ever returned. (And I highly doubt it's even listened to.)
If people like you and I had been able to get someone - anyone - on the phone Saturday, 1050 might not have been nothing but noise for over 12 hours (!!) It was embarrassing in the #1 market in all of Canada.
