John,

Just a reminder, because it's really hard to decipher whether you're asking the legal method to bring in animals from Canada or whether you're asking about smuggling them. BP.net does NOT allow any posts that promote illegal activities.

8. No posts promoting illegal behavior will be tolerated, including but not limited to warez/pirating of copyrighted material, illegal drug or alcohol usage, and illegal ownership or trafficking of species.
If you're trying to figure out how to get CITES paperwork in order to ship animals from Canada to the US, I'd recommend reaching out to one of the larger breeders in Canada, like Markus Jayne Ball Pythons and I'm sure that they'll be happy to answer all your questions and perhaps even help you get your paperwork in order.
