Just very quickly—and perhaps Mr. Warawa can help us with this—we invited Dr. Alfonso Rivera, the head of the groundwater mapping program at NRCan, to appear. But I'm told we're having trouble getting a positive response. I should mention that we had also invited someone else from the groundwater unit at NRCan to appear before the committee in Alberta, and our invitation was declined.
I don't know if Mr. Warawa can speak to his counterpart at the Department of Natural Resources, but it's very important that Dr. Rivera appear. In fact, you and I both agreed he should be invited. So if you can push that along, we'd really appreciate it.
