Apologies if this is the wrong forum.
I just received my 2x Kenko teleconverter from Cameta Camera, shipped here to my house in Nova Scotia, Canada. I was surprised to see that duty was charged (NOT a UPS brokerage fee, I know the difference and the deal there). Looking at the CBSA tax form attached to the package, it says that the country of origin was "JP" (I assume Japan), so is that why I was charged duty? Even though the product itself was coming from the USA?
Actually, the duty was only just under $4...what really hit was the HST (expected) and the $8.50 "handling fee" CBSA charged (not expected...used to be $5, when did it change??)
