Care to list the channels? Some may cease to exist, or may be being dropped due to lack of interest since the changes required by the CRTC to change bundling.
Some of the channels may have been relocated on the list.
BNN can be found at 9815 & 815
ABCSH (don't know which channel you refer to)
SHWHD if this is showcase (guessing) it is now at 9301 and 301
You can search for channels here, and find their listing number.
The main satellite channel guide is here. Both Telus and Bell's websites list BNN as 1568. Unless the channel packages are changing, I can't find anything saying BNN is getting a new channel number or any changes in package. Maybe call Telus and ask.
