I'm still a little confused about outgoing goods. I understand how everything incoming would be subject to inspection and whatever, but for outgoing goods, there's no outgoing tax. There's no tax if it's not a food or a drug. It's not subject to any of the statutes you operate under for food and drugs, immigration, and customs.
Could you please nail down for me the jurisdiction that you would have to interfere with something in Canada being removed, either on a ship or by a truck or on a car on a road? Where would your authority come from?
