The competitiveness of Canadian wireless services has been the source of an ongoing and contentious debate for years. Last week, Canada's telecom regulator concluded that there is a competitiveness problem, yet in a decision surprisingly applauded by many groups, declined to use much of its regulatory toolkit to address the problem. Instead, it placed a big bet on the prospect of a smaller wireless carrier somehow emerging as a fourth national player. My weekly technology law column (Toronto Star version, homepage version) notes that the Canadian Radio-television and Telecommunications Commission began investigating the wholesale wireless services market in 2013. The big three wireless companies - Bell, Rogers, and Telus - argued that the market was competitive and that no regulatory action was needed. By contrast, new entrants such as Wind Mobile called for regulated roaming rates so that they could offer viable national services with more affordable connectivity wherever their customers roam.
