Verizon's curiosity about entering the Canadian market could represent more than just a brief fascination: Reuters claims that Big Red has made a "tentative" bid for Wind Mobile. While the exact price would depend on what Verizon finds in Wind's accounting books, the estimated value ranges from $600 million to $800 million. Neither party is commenting on the rumor, although Verizon may still be open to alternative deals -- it supposedly approached Mobilicity about a potential acquisition. Verizon will likely need permission from both the Canadian government and Vodafone to make any takeover attempt official, but the reported bidding suggests that the company is willing to brave the gauntlet for some 700MHz spectrum and a presence up North.
