Bill,
In Canadawe have very liberal import laws, 5,000 rounds of ammunition each shipment for personal use, any firearm componate (other then a reciever or prohibited firearm parts) is not restricted for import either as long as you have a valid firearms license to own that type of firearm.
Hence why sourcing it from a country that doesn't stone wall its "friends" with ITAR regulations like the US is completely legal for us (browningautorifle& myself) and is done on a regular basis by gun owners.
