Thank you very much, Mr. Chair, and thank you very much, Ken.
The best dilbit studies done by the Government of Canada, in terms of honesty and replicating of natural conditions, are done by Fisheries and Oceans in the Bedford Institute of Oceanography in Halifax. The ones least likely to be accurate, because they were done in tanks of water in Alberta, were done by Natural Resources Canada. There's a preponderance of effort to focus only on the ones that say dilbit floats, and can be cleaned up, based on studies in tanks of water in Alberta.
As the Minister of Fisheries and Oceans, I want to draw to your attention to the really good studies, which have been published and peer-reviewed, led by chief investigator Thomas King. They suggest that you are very unlikely to be able to clean up dilbit; that the oil balls will sink, and you'll have to heat them somehow, underwater, to get them up and out of the ecosystem. At this point, can you honestly tell us we have a clue about how to clean up dilbit, based on studies in your department?
