This is an ongoing issue where certain CBC Music regional stations disappear and are not accessible. I submitted questions here a year ago and contacted support. Recently tried SONOS Support again and they confirmed the issue …
“Indeed, I can see here that only Central, Mountain and Pacific are available at the moment and the ones you mentioned are not working. So, it seems to be a general issue. I can report it forward to our team so that they can investigate however I cannot provide an exact timeframe for a solution as we don't know if it's an issue with our service or from CBC's side.”
They also said they did not have a way of keeping me informed of progress so my issue has kind gone into a black hole. But if others here are having the same issue (still) reporting to SONOS Support might help prioritize a solution.
