That's helpful. Thank you.
Minister Goodale, with respect to countries involved in this, it seems that the bill, as you framed it, is U.S.-Canada-centric, and for very obvious reasons; it's because of the intertwined nature of our two countries. What other countries are involved, and what other regulatory regimes? For example, we've just concluded the Canada-Europe trade agreement. Are there similar arrangements in place with European countries—when travellers enter the European Union or exit from the European Union to come to Canada?
