My colleague from the Department of Finance will comment specifically on the procedure. I'd also like to make the point that in general, a principle of the WTO is that most, if not all, tariff lines are “bound”, which means that they're bound in schedules, and it's very difficult to raise them. An advantage of that principle is that our own trading partners also can't be raising tariffs that would affect our export-oriented sectors as well.
So there is a very rigorous process, both at the WTO and within nations to go forth and change those tariffs or to establish TRQs. That's the reason behind it: to provide predictability for our exporters so they know that the tariff they have to deal with, if in fact there is one, is the tariff which will be there for the longer-term.
