Personally, I think in the last few years it's crossed the line from just left leaning into being a propaganda organ as my GP comment said, and it needs to be called out as such. There was an article on here not long ago about a CBC reporter Tara Henley quitting and going to substack because of how political CBC had become.
Incidentally, all Canadian news media sucks, like everything else in Canada, we have very little choice and everything is basically the same even if it claims to be different. I would not consider any Canadian newspaper / newscast to be worth paying attention to, and get Canadian news from BBC
I'd also add that the political compasses and candidate choosers have been a place where you can see the leftward lean. I think it is a similar root cause to the coverage selection issue.
In The Righteous Mind, Jonathan Haidt talks about a particular failure mode that some people on the left exhibit when asked to fill in a political questionnaire the same way a conservative or libertarian would. I think that is what's happening here.
