ANd now LCN has applied for an HD license, so that will make another French HD channel soon. But I know Videotorn is planning on getting upgrading it's network from 750 mhz to 1 ghz at some point which will bring in more space for HD. I know it seems far down the road but analog channels are on the way out in juts over 3 years. That will bring a lot more space for HD channels in English.
I also think that before that, some channels are going to migrate to digital only. I wouldn't be surprise if within a couple oif years, only the basic cable channels (read mandatory CRTC channels) are going to be available in analog. Rogers as stop offering analog service to new subscribers and Videotron will probably follow at some point.
HBO is a major brand and has major appeal to Canadians, even French Canadians, so I would be surprise if Videotron doesn't get HBO HD. MAybe not this month, but soon enough.
