What exactly are you looking for? Wigs, the outfits themselves, accesories/props?

I've seen them at Anime Xtreme before (on Spadina) they don't have a huge selection of costume stuff so I would suggest giving them a call. Your other option is to commission local people if you want a well made one.
My cosplay goal is to one day have my closet look like Tomoyo's costume van from Cardcaptor Sakura.
