--could not decree in the absolute that the fishery stocks are not threatened. Everything Canada decides in this field must be confirmed, and there is even a peer review. For example, if Canada says that a stock is not threatened, it has to go through, for example, the FAO. There is a peer review there, and the peer review must say that they agree.
My answer to your question is of course it could be threatened, and every country--it's written clearly--could ask questions about the nature of the stock, and Canada must have a decision based on the international criteria and validated by the international environmental organizations, so for sure it's not arbitrary.
