Indeed, the CBC isn't an actual elite that could be defined by achievement, performance, accountability, history, or other merit, but they do groom the lower slopes of it. It's possible they have become more balanced as I tuned them out almost 10 years ago, and perhaps in the mean time they've investigated public service corruption, major party financing and election integrity, foreign influence operations, value for money in spending, threats to Canada's sovereignty and place in the world, challenged dominant narratives, and provided valuable and neutral insight into the culture conflicts of the day, but I'm willing to bet I haven't missed that much.
If you are in the U.S., CBC news is like if a Portland NPR affiliate had the budget of CNBC. Lots of very concerned and appropriately unattractive white people with cameras, descending from billion dollar office towers to hover around mystified minorities (who, quite reasonably, just shrug and go with it) demanding to know how they've been victimized by the Four Bads. (climate change, homophobia, racism, and sexism.) The CBC became the prosecutors in litigating for social justice, which I think many of them would be sincerely flattered to read, but to many Canadians, they are just activists posing as reporters.
This is in addition to that they are the state broadcaster whose mandate was to popularize Canada's increasingly homogenized federalism and (now post-) national identity. Their mandate isn't even reporting, it's narrative, and from a federalist perspective.
That view represents the consensus of a few neighbourhoods and schools, basically Queen's, McGill, and to a lesser extent, Carlton, and the international NGOs they all did their gap years at. It is widely regarded as an arm of the LPC. Their content is a formula of patronizing concern about what should be done about people who don't work for the government, or aren't paid in public money, and it manufactures sentimental conflict over different minority interest groups toward that end. While most media panders to outrage, the CBC's editorial tone exalts victimhood as a kind of new state religion.
I could just dismiss them as just another group of radicals with government jobs, but it's more complex than that in Canada. The CBC is something much weirder altogether.
