I just also heard about an incident at the Billy Bishop Airport, which is on Toronto Island, that occurred a while back. This guy got caught though after bringing drugs, a gun, and a bomb made with what he though was C4, but he was sold fake stuff. He went all the way to Vancouver to get it too. Presumably he flew out and back to buy it, so a thinking man would wonder how he managed to bring it back on a plane without getting caught?
