Just to pick up on the issue of dredging, it is something that we are spending more and more money on every year. As the deputy minister noted, climate change is complicating things, as well as the larger vessels to which you referred, meaning that we have to dredge at a greater depth.
We have more and more cases of emergency dredging that are more frequent and unpredictable, so we are trying to better predict what kinds of emergencies we might be facing, and we have been working with harbour authorities to do a better job of that.
We've also identified contractors to provide services under much shorter service, so it is something we are working on very seriously.
