After going through this whole thread, it appears to me it may be specific to items that are for Military use and thus manufacturer/item specific. As Ryan said the manufacturer contact him and said that their plates are now a Controlled Good. Furthermore the references posted say “Body armour and protective garments manufactured according to military standards or specifications, or equivalent, and specially designed components therefor.” So I guess the question remains, are all body armour items controlled goods, even if they are made specifically for civilian use? I am no expert, but it does seem odd that these regulations were introduced years ago and no one seems to know about them, provinces have even introduced subsequent legislation. There are still other dealers selling it. How does this make any sense?
