Round number: roughly double, $400Cdn or a little more. Try not to use UPS, or you'll have to pay their $35 "brokerage fee".
Example: I ordered a used Cambron 2x converter for Pentax 6x7, advertised at $75usd. Add $15usd for shipping, then came exchange, GST, "brokerage fee", and the total was right around $200cdn. In that instance, it was still a good deal, but more than I expected to pay. Pat White
