As the unamended act reads now, there are two points at which a product is caught. It is caught at the point that it is imported into Canada, and that has not changed. It is also caught only for a product that is, let's say, for example, manufactured in Ontario at the point it crosses a provincial boundary. That's in the existing act.
The amendment merely says that at any point that a product crosses a boundary that the federal government is able to regulate, that product must be compliant--that is, no substandard products can be shipped between provinces or imported into Canada. This does not have NAFTA implications, basically because it imposes no stricter requirements on, say, an American manufacturer than on an Ontario manufacturer. There would be no NAFTA implications.
