I want to go now to Dr. Lin. You mentioned the Nature paper, which I think was a great thing to come out of Environment Canada science. It showed again that there was a large hole that had formed over the Arctic.
Maybe you can elaborate for the committee on what Environment Canada is now doing with this data or this finding. What's the next step? Does it mean that the ozone hole...? Has it shrunk?
What are we seeing with that data, the follow-up that came from that paper?
