It seems that is often DHL , but we also see other shippers used for last mile delivery, including Canada Post for rural and isolated destinations.

Import duties, taxes and charges are not included in the item price or shipping charges. These charges are the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to bidding/buying
Basically, you are paying the import fees on delivery because they were not charged on purchase.
But no matter when import fees are charged, they are paid by the buyer/importer, not the seller or the shipper.
