TVA has applied to the CRTC to launch a channel aimed at preschoolers called TVA Junior. (http://www.crtc.gc.ca/eng/archive/2009/2009-632.htm#3)

I guess this explains why Astral has not been successful in launching Vrak Junior, TVA had plans to launch their own service. Pretty hard to launch a channel in Quebec if you can't get carriage on Videotron, the main cable provider.

I don't really see why they want to launch such a channel when they don't own any other kids channels?! Astral owns 3 (Teletoon, Teletoon Retro & VrakTV) and has the resources (programming) to launch another. In any event I think a channel targeted at preschoolers would succeed and there currently is no French equivalent to Treehouse.
