Neither CBC, ABC, or BBC are "infamously left-leaning". They are very much all center. That's literally one of their biggest criticisms, that they're too "boring" by not taking more of a stand on anything.
Also, important to note: Rupert Murdoch is directly involved in the funding of trying to convince people that these public broadcasters are "too left leaning". For his own profitable gains, as the more people turn away from them, the more they turn to stations he owns. Something to think about.
Which has very little meaning as "true" can mean whatever you want it to mean. BBC, ABC, and CBC have much higher journalistic integrity than their private counterparts.
True journalistic path is not about the truth but about the dispensation of facts in a way that will help the reader make an informed decision pertinent to themselves and its surrounding.
Otherwise, we have "National Enquirers" infestation and all those who are yellow-journaling in their chasing of the last revenue pool.
