People complain that it makes them biased but I don't really think so. At least not currently. For example CBC Power & Politics is decent programming and its not some one sided political overage at all.
In the recent past a lot of Canadian news outlets were incredibly cringe. Woke is now a poisoned word, but they were the cringey kind of woke where any criticism of foreigners for any reason was considered racist. A lot of that was Justin Trudeau Era institutional behaviour that has stared to go away though. The remaining holdovers being some courts and judges mainly.
I think lot of the distrust of news in Canada is a (somewhat reasonable) holdover for when they acted like this.
For Americans reading this though, this is all a completely different baseline compared to American News media. Canadian News might as well be true neutral in to the polarization down south.
