Yep, last year I attended the one in Calgary.
They have very good instructors, no doubt about that. Depending on your age and your main instructor (whom follows you throughout the day), you get worked pretty hard.
Typical hockey camp, but I'd say a lot more thought went into this one, compared to some other ones I've been to. The dry-land shooting setup was pretty neat, in the curling rink (that's where ours was), I clocked a steady 70 MPH slap shot

.
Assuming you don't get brats in your group, it'll be a great experience for your kid.
Edit: Adding to Jake's comment about the slack dry-land. I had a pretty tough dry-land guy who worked us pretty hard, as did the rest of my instructors. Let's just say I was dead at the end of each day.
