MONTREAL - Quebecor CEO Pierre Karl Peladeau is expected to lift the veil Tuesday on his plans to launch a conservative television network.

The billionaire media baron has called a news conference at the Toronto Sun building to announce a "new investment in Canadian media."

Quebecor Media Inc. (TSX:QBR.B) has been filling its ranks ahead of the apparent efforts to start an all-news network.

It tabbed Prime Minister Stephen Harper's former chief spokesman, Kory Teneycke, as vice-president of development, and he has reportedly been developing a project modelled on right-wing U.S. channel Fox News.

The company also hired David Akin, a correspondent for Canwest News Service and Brian Lilley, former Ottawa bureau chief for Astral Media Radio, Canada's largest private radio broadcaster.

Other on-air faces are expected to come from CBC and other rival networks.
