The standard def channel is on 156 (channel 137 in Hamilton, ON).
The HD channel is on 267. You may however not have this channel yet as it is only available in areas that have gone through the DNU (Digital Network Upgrade). - You also need an MPEG4 digital box. (A lot of new HD channels as well as NFL Sunday Ticket and NHL Center Ice require these newer DCTs).
The Pace Summit, DCX 3200, DCX 3400 and the Shaw Gateway are all able to broadcast in MPEG 4 if you're wondering what can play the channel. (I sadly cannot get it due to having an older 3416).
