I would say, first of all, auto parts tariffs currently in Canada are zero and have been since 1998, so that right now, parts can come in from anywhere duty-free without any kind of rule of origin. That has been the case, because the duty remission programs that were in the NAFTA were eliminated and that was the response Canada gave at that time in order to effectively support the manufacturing operations here in Canada.
The second thing I would say is NAFTA doesn't guarantee any country-specific sourcing. A part could have zero Canadian content and still be NAFTA compliant.
The competitive pressure on parts makers hasn't really changed with respect to the TPP, but that said, because of the way just-in-time assembly works in most vehicle companies these days, which is that you look first at the local supply community, maintaining a footprint in Canada is good for and critical to maintaining the Canadian auto parts sector.
