Ezra Levant discusses this in today's Financial Post:
... The CBC is the obvious example. In the recent federal election, the NDP and Liberals battled for the hearts and minds of the CBC’s journalists. Thomas Mulcair started the bidding with a promise of a $115 million annual CBC bonus if he were elected. Not to be outdone, Trudeau upped the ante to a whopping $150 million. The politicians were brazen: they were offering the journalists who cover them a success fee [using taxpayers' money] if they were elected.
... The Canadian Media Guild, the journalists’ union that dominates the CBC as well as The Canadian Press newswire, formally registered as a “third-party” campaign group with Elections Canada, ... Every unionized journalist covering the election was contributing part of their own salary to an anti-Harper election effort.
... It’s not just CBC journalists who are corrupted by being politicians’ pets. Journalists at private media are, too. As they nervously polish up their LinkedIn resumes, they can’t help but notice that the only major, national news organization still hiring is the CBC ... How many private sector journalists are tailoring their own work now to mirror the editorial line of the CBC where they hope to be in six months?
