If I may add to that, I think it's important to recognize that “Validation Improvement Roadmap” as a work in progress. I have—I'll be completely honest—stated my concerns with the objective that you just read as it is stated. A big part of my job is not only to ensure that the minimum safety standards are met for everything that I sign off on in Canada but also to make sure that there is a level playing field amongst the various manufacturers. It's a highly competitive business. Certification costs a lot of money. For every decision that we may make to say, “No, manufacturer, you have to do one better or you have to do one more test,” I have to consider whether that is a fair and level approach vis-à-vis how the other authorities treat their manufacturers.
If we were to, as that phrase states, move to complete reciprocity on all products, we would lose the ability to calibrate those decisions against what those other authorities are doing. I believe that's a very important element. That said, there are certain categories of products we have already today for which we have direct reciprocity with no review. That's done on a risk basis. It's not done for large transport aircraft such as the Boeing 737. Personally, I don't think it will ever get there. It's simply an evolution of the degree to which we can rely on, if we choose to, the work of the other authorities.
