Bell Aliant Inc. is expanding its FibreOp fibre-to-the-home network to Sault Ste. Marie, Ont., the company said. In a release Wednesday, Bell Aliant said it will invest $15 million to roll out its fibre network past 24,000 buildings and residences in the Northern Ontario city. The move will allow the company to offer fibre-based Internet and TV services, the company said, with Internet download speeds of up to 250 Mbps and uploads of up to 30 Mbps. The company did not say by when the rollout will be complete. Bell Aliant, which is controlled by owner BCE Inc. by 44-per cent, operates its fibre-to-the-home network in Atlantic Canada and in Sudbury, Ont. The company said Wednesday that its Sudbury network now passes 33,000 buildings and that it aims to pass 800,000 across Sudbury, Sault Ste. Marie and Atlantic Canada by the end of 2013. The CRTC said in March that it granted Bell Aliant a licence to offer TV services in Sault Ste. Marie.
