I would say, in terms of items that have been blocked from entering the U.S. system, there is a healthy collaboration that takes place between the U.S. CBP and Canada Border Services around sharing information, especially around re-exportation, which is a concern, so that it doesn't get redirected into Canada.
Again, I can't speak to the specifics of the case that's being identified, but I do know there are regular exchanges between ourselves and the CBP around such issues as re-exportation, where there are concerns with the goods that are trying to be imported into the U.S.
