I don't comment on the credibility of competence of individuals.
What I see, however, is that the CRTC is governed by legislation. Its decisions throughout its history have been upheld by the courts. The most famous decision that could be invoked by people who think that the CRTC is a censorship bureau or inquisition tribunal is the decision not to renew the licence of a Quebec City radio station in 2004. The Federal Court confirmed that the CRTC properly applied the rules and did not violate freedom of expression. That has been confirmed by the Supreme Court.
