Bell Canada Inc. says the CRTC should consider guidelines, as opposed to formal rules, in an effort to ensure diversity of Canadian programming. The proposal came during the second day of CRTC hearings, in which the regulator is looking to establish policies aimed at protecting Canadian content in a consolidated media sector. So far, the CBC has sided with the CRTC’s proposed plans, while Quebecor warned against the risk of being swept away by such global giants as News Corp. and Google Inc. The hearings are scheduled until the end of the week.
