I am a UK resident, and will be traveling to Toronto, Ontario in a couple weeks. I have ordered a laptop from a US company who state:
International orders ship via UPS. Generally, shipments are delivered within 4 business days of shipment. UPS will ship your computer to the nearest customs office. Once customs clears the package, you will be contacted for delivery authorization to your residence or place of business.
UPS service includes shipment and insurance. [We do] not collect taxes or duties for orders being shipped internationally. To determine taxes or duties owed, if any, please contact your customs office with both the description of your order and its total price.
The Canadian Government's calculator suggests I will owe a couple hundred dollars.
I will only be in Toronto for 2 days, and I'm shipping to a business address - but I cannot expect the business to pay the import duties on my behalf. How will the duties be collected, and will it be a time-consuming process?
