Some of it is through discussion. We have our reports on plans and priorities, a departmental performance report. We have to look at the activities and see if in fact we achieved some objective. As I said in answer to a previous question, Mr. Chair, sometimes it's difficult to say we won, that this is the year when Canada's goal was actually met because some of these.... As we know in the Doha Round, this has been going on for a decade, for a very long time. We won't see an immediate outcome. All we know is that we win some battles on, one day and if we weren't there we would have lost those. The sealing file is a case in point. It changes every single day, and it continues to change. The votes are happening as we speak, so it's hard to say.
I think the example Ms. Ridgeway has used, the bottom trawling, is a useful example, since Canada did benefit. To say year over year that Canada benefited by some amount is very hard to say. It's very hard to measure, unlike some other things we do.
