I have3 never sent anything to Canada so I don't know the best service. I checked the U.S. Postal Service price and it is about $10 more than what I expected for US shipping (USPS First class). I'm not sure that they have a tracking number with this service though and they did not say how long it would take.
With the additional postage, I'll sell the YS-110 to you for $95US shipped to Canada. If you want to still by this, my PayPal account is this email address and I will need your full name and address for the custom's sheet.
