As a more general response to a question I just received, you can still register for LSA West, in Vancouver BC (July 26 - Aug 1). However, you should do so soon, if you want to be sure of on-campus accommodations. That's first-come-first-served, and something that Early Music Vancouver doesn't have much control over (other programs also take advantage of on-campus housing).
