soulreaver, Intl. shipping has to be handled on a per-incident basis, the default amount is for US orders. We ask that International Customers email shop@ before ordering. However, the item you're ordering is quite small and light, so go ahead and place the order w/ the default US amount, and it should cover Airmail to Canada. RE Warranty, this is handled by the manufacturer, but they are very easy to deal with, and if there is ever a problem, we're always here to step up to the bat for you. Thanks!
