The Canadian carriers currently are obligated to check against the U.S. no-fly list for flights into the United States, and under passenger protect, they will be required to check for flights leaving Canada under our program. For overflights, that's a matter that's still currently under discussion, a matter of concern, but in terms of Canadian air carriers, it's for flights landing in the United States where the obligation exists.
