Recently had two orders from MiniSpares to Canada. Both came by courier (DHL; postal shipping to here not an option from MS). First order had a "brokerage" fee charged by DHL once package was in Canada. This fee is to cover import duty/taxes and the courier's typically "juice" it up with their one special "handling" surcharges...basically to cover filling in the customs paperwork. This was some $50 on top of the $60 shipping cost applied at MS checkout. Second order, which was for more than double the first's value, only had $17 brokerage. The box from MS had "Antique Car Parts" scrolled all across it. This likely gave it some sort of exemption from Canadian import duty.
Be sure to request this designation if you are ordering anything from outside Canada.
