I can give you some information, but I'm not an expert in this area.
When a country signs the United Nations Convention on the Law of the Sea,
when a country becomes a signatory, it has ten years, basically, to do the analysis and to submit its claim under the clause on the continental shelf. So that's the work Canada is doing right now. We have until 2013. Each country will have a different timetable, because it depends on when they signed the convention. For instance, the U.S. hasn't signed yet, so its clock hasn't started to tick. Russia signed before us. Each country is going at a different pace.
