My apologies, but we're actually not able to provide you with details at this moment. We can follow up, perhaps in a few minutes, on precisely how the number is referenced in the IBWTA regulations themselves.
I would like to make a couple of points on the 50,000 number and its relationship to environmental impact that maybe the committee would be interested in.
First, you will recall the point that was made by the experts you heard, from the Munk School, who observed that 50,000 litres a day would be insignificant in terms of the impact on the quantity of water or the flow of water in or out of Canada.
The second point that may be relevant is that the flow of a typical international river would be approximately 1,000 times 50,000 litres a day. Again, it may be reasonable to conclude that the number is a relatively insignificant number related to the environmental impact, setting aside completely any of these trade considerations that we've been discussing.
