Even I can't order receivers without them being confiscated. AV is only an internal policy on this site and not law.
Secondly, plastic or metal they'll still get confiscated.
Finally, yes they do ship to Canada but it's not their problem if you get your shit seized. I think, once they've shipped it, they've fulfilled their obligation to the buyer and anything that happens after that (ie. Border Services seizure) is the customers problem (although with insurance claims for lost/damaged packages and stuff they'll probably help you out).
