Thank you, Mr. Chair.
Thank you to both witnesses for your testimony.
I'm just trying to understand the historical arc of this issue. It was very interesting that you mentioned that the first time governments really got concerned with water quality in the Great Lakes was 1964 and that led eventually, as I understand it, to the Great Lakes Water Quality Agreement in 1972. My understanding is that the agreement's focus was initially narrow. It was to look at the problem of phosphorus, is that correct?
Then I imagine over time other issues were dealt with jointly by the Canadian and American governments within the framework of that agreement. It sounds like where we are now is that we have phosphorus out of detergents and I presume we have our house in order when it comes to waste water effluence. We've had enough time to make those investments.
Now the problem appears to be—and please, after I finish, I'd really welcome a correction on my understanding of the issue.... What we seem to be talking about is agricultural runoff and the phosphorus from that source. Is that a correct understanding of the arc of the issue, if I can put it that way?
