Okay. On commercial air services, as I mentioned, there are definitely types of commercial air service that would be an appropriate candidate for designation.
Yes, with respect to aerodromes. With the number of aerodromes we have in Canada, it's very low risk.
On air navigation services other than Nav Canada, there is currently another small air navigation service that could easily be designated.
With respect to manufacturers of aeronautical products, there are all sorts of aeronautical products. They need to meet specific certification criteria and they will still need to meet those criteria. They don't necessarily need to be licensed as manufacturers per se, so I don't think it should be there.
