I would say a couple of things. Because it's a program that's used around the world, I think it's important to recognize that there's confidence in airlines in like-minded countries that use this program. It is very robust, but I also think it's important to take a look at what evidence is out there.
As an example, the Transportation Safety Board presented a report to Parliament last year that showed there was a 25% reduction in accidents over the past 10 years. That's due in large part to the kind of robust oversight that Transport Canada has put in place, including this check pilot program.
