Quebec-based Videotron launched its wireless business Thursday, taking on established players Rogers, Bell and Telus in what could be the start of a price war in the province.

Quebecor chief executive Pierre Karl Peladeau made the announcement from Quebec City.

He told the audience he built the 3G-plus network to ensure the future of his company.

Videotron is expected to impact Bell the most with bundled offerings that include TV, home phone, internet and wireless services.

Bell and Rogers each have slightly more than one-third of the wireless market in Quebec.

Canada's cellphone industry is experiencing new competition for the first time in years, with the introduction of several other new players, including Wind Mobile and Mobilicity which don't operate in Quebec.
