The Globe and Mail reports in its Saturday edition that the CRTC has upheld its decision allowing the big telcos to resell Internet services through rivals' fibre networks, siding with arguments made by Telus in a long-running policy debate over competition in the sector. The Globe's Irene Galea writes that the verdict prompted strong reactions from other companies and industry groups opposed to the decision. Given the steep cost of building infrastructure, the fibre wholesale framework was designed to improve Internet affordability and competition by giving new market entrants an opportunity to piggyback on existing networks. The government previously required three carriers -- Bell, Telus and SaskTel -- to give competitors access to their fibre networks at regulator-set rates. The latest question under review was whether the country's Big Three carriers would be allowed to take advantage of the mandated rates as well. The CRTC on Friday reaffirmed its 2024 decision that Telus, Bell and Rogers could expand into each others' fibre networks where they do not already have their own infrastructure. This means that Telus, whose network is primarily in the West, can expand over Bell's networks in the East, and vice versa.
