What the H type/brand of liquor costs $4000 a bottle??

I would expect to pay GST & maybe percentage duty. Trouble is, IIRC the Canada Customs form at airports asks for the value of all the goods. If U were driving into Canada, U could probably answer the 'Anything to declare?' question with, 'Yes Sir/Ma'am: 2 T-shirts & a bottle of liquor.' Very few officers would ask U the price of the bottle because they'd never dream it could be >$800! So they'd wave U thru!
