Thank you.
Not all countries have visa requirements. Mexico, for example, is one of those countries. Nonetheless, we do work with both visa and visa-exempt countries through what we refer to as our migration integrity officers. We have officers posted abroad who work with the airlines to try to determine who's getting on the flights and whether they are properly documented, etc.
At the same time, if airlines allow people on the plane with improper documentation, there is an onus on those airlines to pay for their removal from Canada back to their country of origin. One of the points raised by the Auditor General is that we have to make sure we're tracking and assigning those costs properly. There are improvements that we've made in that regard.
There's a significant difference, obviously, in terms of how we do our business and the responses we have between countries that have a visa requirement and those that don't.
