I'll touch on the first part of your question first.
With respect to limits and in terms of surveillance technology, all types of ship traffic that we're talking about, particularly the traffic that comes under the proposed moratorium that would prohibit over 12,500 tonnes, are required by law to carry the automatic identification system that transponds their signal, as well as a lot of other data about the ship itself. That is one of the primary systems that we use to monitor shipping through our waters across Canada, including the west coast in this case. That system is very reliable. It allows us to see exactly where the ships are.
I should talk a little bit about all the reporting that goes on before any of these ships come into our waters, the 96-hour PAIR report. That gives a whole range of information that ships need to report 96 hours before they even enter our Canadian waters. That includes the type of cargo, the ship's name, and all that type of information that we can use to assess the risk of that ship coming onto our waters.
The AIS, the automatic identification system system, is one of the main systems we use, but the other one that we use particularly is radar. That gives us a much closer, more accurate view, depending on where you are, of particular areas of risk that we see across Canada. In this case, we're talking about the west coast. We have radars on the west coast already in particular areas. We're installing six new radars on the west coast that will allow us to see particular areas that we feel are more at risk. The capital project that is installing those will go further than that later on as well.
That radar and AIS information gives us—I'm not going to give a percentage per se—a very accurate view of the traffic that we're talking about in our waters, anywhere from the barge traffic that Mr. Donnelly was talking about with the Nathan E. Stewart up to the largest tankers.
