Been quite a while since CHED wasn't in the Number One spot.
But the numbers indicate it was more of a huge CISN gain (+1.1), than a CHED loss (-0.3).
NOW-FM went from a tie with Capital-FM to a 0.1 lead.
Much more interesting is CFCW-AM being very close to beating Easy Rock. Which brings up an interesting question about the most listened to music-based AM station in Canada: see viewtopic.php?f=14&t=8524&start=0
