Finding availability for three people to travel together in summer is a challenge, but it shouldn't be impossible. August 2014 is opening up slowly. Right now I can see 3+ award seats to YVR in CW and another 3+ in F on 1 July.
I suggest you search for -- and book -- each direction separately (unless you're using a 2-for-1 voucher).
