Thank you for your question.
A lot of the work we're doing currently is all about partnerships. There is a very good partnership between the state and federal levels across all the states, as well as here at home with the Province of Ontario. The study you're referring to by the Great Lakes cities and St. Lawrence Seaway mayors is a study that was to support work that the Army Corps of Engineers is doing for the United States government, looking at that physical separation.
It is an American product. We have been briefed on it through some of our binational committee meetings. I'm not certain physical separation is the end-all for these problems of invasive species, because as David mentioned in his remarks, there are other vectors where these critters can get into Canada, live trade being one way that gives us cause for concern. But there is an awful lot of work being done on the American side on that. I can't say with certainty, but I think there are another couple of years of work left on that study.
A number of different approaches are being looked at, but I think the most important element of this is that at this point, while we may be finding eDNA above the barriers, the physical barriers that are in place do seem to be working, and we have not had any Asian carp getting into the upper waters coming into Canada.
