It's a never-ending topic, I'm afraid. We have done quite a lot of work at the National Research Council facilities in St. John's, Newfoundland, at the oceans technology institute, but the particular study you mentioned that the professor was working on was not sanctioned by Transport Canada.
We have done several studies. Our latest one, in fact, was on the vessels in the Great Lakes, which are a quite different type of vessel, and we've done some analysis there for consideration under the proposed regulations. However, the work that is done there is available to us and it's part of what we have used to make proposals.
