Of course they are.
Eventually, there will be no Std Def'n TV or channels.
By the time that happens, the current fleet of satellites will be retired, and all HD channels will be broadcast from the new G1 (not launched yet) and the future replacements of the two current satellites.
And when that happens, there will be no StarChoice/Shaw TV south of the border.
In my opinion, this is still a big mistake because of all the Canadian Snowbirds who flock to the southern USA and Mexico for the winter.
They're paying their bills, and would gladly watch Cdn TV, if Bell and Shaw provided the satellite coverage.
As of early July, there is NO BELL TV available in the southern USA or Mexico.
Shaw will follow with the new G1 sat and any future replacements.
BIG MISTAKE I think.
Not being a satellite/computer/HDTV techy, I'm sure there's a good reason for doing this, I'm just not sure what it is.
