Mirko, the CRTC would likely have continued its policy of permitting sim sub if Bell had not told the public that the reason sim sub was occurring was that it was a mandatory policy of the CRTC to replace US ads with Canadian ones. It wasn't mandatory to do that, it was Bell's choice. The CRTC was irritated that Bell constantly mischaracterized the policy and replaced sim sub with the current policy of no sim sub. The blame for the change lies with Bell.
