homebrew and customs (Attention canadians)

I remember a bit of discussion about crossing the US/Canadian border with homebrew and not knowing the legality of it. I finally bit the bullet today and sat on hold for 25 minutes with U.S. customs to find out they don't care who made it. Homebrew is treated just like commercial beer. You get 1 liter free per person, then pay duty after that.

Ok so I do most of the import & export for my particular division of my company (um in the top 50 of fortune 500 this year) and am similarly perplexed as to how US customs interacts with our northern border. Somehow my chemical shipments act just like domestic shipments. God forbid you need to ship to MX or ER, however, then you are in for some real customs scrutiny. Sorry....RANT induced by no one covering my work during vacation absences! : )

Good luck with homebrewed hooch though, seriously!
