KSC guns are even out of stock overseas. I'm not sure what the problem is but from what I understand there's a supply issue somewhere. The alternative is to try and find a KWA, they're rolling out guns using the same system as the KSC. Hell you can even probably get an NS2 (KSC "System7").
As for getting them in Canada not likely unless you're AV'ed and even then I'm not sure if you can get BNIB (because of the overseas supply issue).
