The CRTC did order CHOI-FM to be shut down, and they lost the lawsuit and all appeals, so they would have been shut down. But at the last minute they were bought by another channel with a different CRTC licence, which saved them from the shutdown order.
I understand. My point was they shut it down because they used "bad words" and insults, not because they violated Canadian law. The idea that the CRTC only shuts down stations that are violating Canadian law is not true.
By the way, I used to listen to that radio station and it was pretty mild compared to what you often hear on American talk shows. They were occasionally disrespectful towards some celebrities and politicians, but that's it. It's clear to me that they were unfairly targeted for being the only libertarian-leaning radio station in the province. 50,000 people marched in Quebec city to contest the decision, the largest such march since the 1960s.
