The CRTC has again issued warnings to Bell Canada and Telus Corp. over recently introduced fees that the regulator says could be in violation of its new policy prohibiting telecoms from charging customers when they activate, change or cancel plans.

In letters addressed to the two companies on Friday, the day the new rules took effect, the CRTC’s director of social and consumer policy Nanao Kachi said Bell and Telus have until Wednesday to confirm they have ceased charging the fees in question.
