There are actually two parts to that. The two parts are those vessels under marine pilots' care and those that are involved in the domestic trade, such as the tug and barge traffic. The larger vessels under pilotage do have specific shipping lanes that they tend to follow. That is not always the case with the domestic traffic with a shallower draft and the ability to move in many other areas.
We are presently working with the pilots group to actually formalize the traffic areas so that as you move forward through the MPAs, those can be presented and everybody will be able to see exactly where certain-sized vessels will be able to travel and where they won't be able to travel.
In Prince Rupert specifically, there are three traffic lanes that we use, but they are not formalized. They are not IMO approved as they are in the south.
