Yes.
There is no need for you to know how much the customer is paying in import fees to his own country because you are not paying any eBay fees on that amount.
You are paying fees on the selling price, the shipping that you charged and will use with Canada Post, and perhaps the customer's sales tax*
You will be paying fees on the part of the customer payment that you handle, and you are being shown what that is.
*With direct shipment, we do pay fees on the ENTIRE customer payment, including their sales tax, but not with eIS.
EIS is a Seller Protection program, and offers little to the buyer.
