The Globe and Mail reports in its Saturday edition that in the coming weeks, U.S. Trade Representative Jamieson Greer is expected to begin talks over the renewal of the continental free-trade pact, the Canada-U.S.-Mexico Agreement. The Globe's Mark Rendell writes that will formally start the clock on one of the most consequential trade negotiations in Canada's history. Brian Kingston at the Canadian Vehicle Manufacturers' Association expects the U.S. to again push for higher North American content, and to demand on top of this that a specific portion of each vehicle be made of U.S. car parts. "We are already at very high levels of U.S. content in Canadian-produced vehicles. The question is, do you want to codify that? Which ultimately does reduce the flexibility of a manufacturer based in Canada to use and source parts and components from other parts of the world," he said. "When we're talking about rules of origin in auto, you can only push content so far because in some instances you simply don't have the capacity in North America to build some of these parts and components and to do so in a cost-competitive fashion," he added. Odds are, the President will see the negotiations as an opportunity for a shake down.
