In another setback for the Canadian governments plan to introduce more competition in the wireless sector, private equity firm Catalyst Capital Group has withdrawn from a government auction of prized wireless airwaves. The governments rules for the upcoming auction, as well as for one held in 2008, are aimed at lowering consumer prices by breaking the stronghold that Canadas three dominant players -Rogers Communications Inc, BCE Inc and Telus Corp – have on the countrys mobile phone business. Ottawa says the upcoming auction is designed to ensure there is a fourth competitor in every wireless market in Canada. But new entrants have found it hard to survive in the Canadian market, and some analysts and company executives have complained that government policies have confused and spooked investors eyeing a move into the countrys telecoms industry.
