Thank you, Chair. I appreciate that clarification.
I'd like to ask a question on the baseline and carry on from some of the questioning by Mr. Calkins.
In the summer you have a natural leaching of hydrocarbons into the Athabasca, when the bitumen warms up in the warmer temperatures. We've heard that in the colder temperatures it's like a hockey puck, so it's not naturally leaching to the same degree. So through you to the witnesses, is there testing year-round, and do we find that during the summer months, the warmer months, the amount of natural leaching is higher? And how does that possibly impact the health of Canadians?
