I'm actually in the same boat and I'm also coming from Alberta (Sherwood Park). The earliest my kids can come will be January (end of school term here). What I've been told is "if there's space". My wife and I have talked about it and if there are no suitable openings for my 15 and 11 year olds, I'll come unacompanied for the first year (there's more flights home for singles than married with families so it should be OK).

I will of course start to look as soon as I get there. Hope that helps.
