It the EW Reg't running the course, AFAIK.
Yes, 21 EW is running the course, led by their Reserve Sqn.
As for details, are you loaded on this course? If you are, joining instructions should have been sent by now, or will be out shortly and they contain the info you need.
Skeletor: They're using McNaughton side, only use the new dining facility on the Vimy side. For quarters, the BMQ-L thats running now was housed haphazardly in the mods (B-77). AFAIK they are working on getting them into proper quad rooms for subsequent courses.
