The Globe and Mail reports in its Monday edition that some of Canada's telcos are challenging the CRTC's efforts to open more of the country's broadband infrastructure to wholesale competitors. The Globe's Alexandra Posadzki writes that the CRTC requires telcos that own broadband networks to sell wholesale access to third party operators such as TekSavvy and Distributel at rates set by the regulator. The system, which is set to be expanded in new rules announced by the regulator in November, is intended to encourage greater competition and consumer choice in the Internet market. Bell Canada parent BCE has mounted a legal challenge to the regulator, and on Friday won leave to appeal the CRTC rules. The company last week announced 4,800 job cuts, laying blame in large part on the regulatory system. Cogeco Communications is also unhappy with the current regulatory regime, saying it is effectively giving big telecom companies undue access to Cogeco's network since many of the small competitors have been acquired by the country's major players. Cogeco is urging the CRTC to prevent the Big Three telcos -- BCE, Rogers and Telus -- from taking advantage of the wholesale regime to maintain and extend their market dominance.
