CRTC commissioners are gently co-opted by the industry they regulate, and are often reluctant to endanger job prospects in the industry once their term expires.
CRTC commissioners are appointed by the government, in a quasi-political process. The length of appointments are standard, but they do not all expire at the same time, so often you have commissioners appointed by different governments. I am told by commissioners that the government doesn't try to influence the commissioners too much, but these are people who have come to the attention of senior politicians and have many friends in the political process.
The political interference is low, but the real problem lies with the industry. A former commissioner once explained it to me. There are many opportunities for broadcasters, telephone company execs, satellite companies, etc. to mingle socially with commissioners. At some point, a senior executive will ask a commissioner a bit about how they enjoy the job, what they like best, etc. Slowly a dialogue ensues, often over several months. At some point the exec praises the commissioner's grasp of the industry issues, and asks what the commissioner plans to do once the term expires. If the commissioner is vague, the executive talks about how his company is always looking for people with "regulatory experience" and that salaries are usually much higher than what a commissioner earns. The exec says something to the effect of, how it would be improper to talk about it now, but if you're interested, come see me at the end of your term and we can talk.
Another exec may have a similar conversation with that same commissioner, because it doesn't hurt for that commissioner to see the "demand" for their services from the industry.
And that, is why the consumer gets screwed by the CRTC on most routine decisions. Examples:
The CRTC, facing complaints from AM radio stations about the increase in top forty FM stations, required FM stations to play a majority of NON-hit music. (eventually rescinded years later)
The CRTC allows Cable TV operators to deny "a la carte" purchase of specialty channels, and allowed cable companies to sell packages of channels which always included several channels that were not wanted by the majority of subscribers.
The phone companies get to charge you almost $3 a month extra on your phone bill for touch-tone dialing, even though you can't order a rotary dial service. The truth is that touch-tone dialing actually saves money for the phone company.
Now, the public is realizing how much they've been screwed by Canada's telecom industry. "Cutting the cord" in terms of dropping cable TV and getting Netflix, dropping the wireline phone company in favour of VoIP, is saving some families thousands per year.
