Perhaps it is too soon to speculate, but what will we lose? All of the SD
channels currently on 107?
From what I have read and from what posters have said in previous threads, they will use this satellite for additional ("new") channels, and that whatever is currently available in the US via Anik F1R and Anik F2 will continue to be available in the US for the forseeable future, at least. All this is "unofficial", however.
It certainly is going to result in a lot of cancellations to Shaw Direct's
service. I think that the grey-market for Shaw likely accounts for a good
percentage of their subscribers.
While this is probably true, keep in mind that, legally, Shaw is not supposed to provide service outside Canada. Perhaps they are under pressure from the "other" Canadian provider and from the CRTC to squelch the grey market, and this is their first step in doing so...(?)
I would be curious to know if it is possible for them to adjust the beam
after the satellite is launched. Could they re-focus the beam so that it
reaches the entire continent after it is launched?
I think the real question is not "could they?", but "would they?"
When I first got into the grey market world, I was advised by my equipment provider to think of it from the point of view of a "temporary investment in entertainment". I don't look forward to the day when I lose their service altogether. So I'm trying to take Iceberg's approach......enjoy it while you can.......

.....easy for him to say in Minnesota, however; I'm just a bit further south than he is.....
