Triador can get KSC parts (which are compatible with KWA almost all the time). However, you don't need any kind of good relationship with KWAUSA. While they only ship to the US through their site, if you call them and have a credit card, they will ship unrestricted parts to Canada. Make sure you ask them to FedEx it... the tracking is better that way. I had the USPS lose a package from KWAUSA, had to go through my credit card to get a refund.
