Quebec Roaming Fees Lawsuit Could Cost Big Telecom Millions

MONTREAL — Canada's largest cellphone providers are reviewing a Quebec Court of Appeal ruling that authorized a class-action lawsuit against them in the province over roaming fees.

Toronto-based Rogers Communications, which operates Fido, along with Bell and Telus face the prospect of a trial that could result in them having to pay millions of dollars to customers allegedly charged excessive international data roaming fees.

Rogers and Bell said they are studying the Wednesday ruling and declined to say if they will seek leave to appeal to the Supreme Court.

Quebec's high court this week overturned a lower-court ruling that rejected an application filed on behalf of Montreal Fido customer Inga Sibiga, who was billed $250.81 in extra charges for using her cellphone during a 2012 U.S. vacation.

The lawsuit claims the charges were "exploitative'' and ran afoul of Quebec's Consumer Protection Act.

The ruling comes amid a CRTC report that said Canadians pay some of the highest prices for mobile phones compared to those living in the other G7 nations and Australia.

The class-action lawsuit will cover hundreds of thousands of consumers residing in Quebec who were charged more than $5 per megabyte after Jan. 8, 2010.
