Port operation is a tricky business. Most are owned by the feds but operated independently and controlled by the harbour authorities. There are some that are private but come under fed laws. Alcan smelter in Kitamat being an example of this. ReoTinto Alcan owns the facilities but we had to take a little course on federal port rules and anti terrorism to work on the equipment down there even though the only goods moving there are parts for the new smelter and the only access is through RTA roads.
