The Globe and Mail reports in its Monday edition that for the Canadian business leaders and politicians descending on the U.S. capital, today's inauguration of Donald Trump promises to be unlike any other. The Globe's Nathan VanderKlippe writes that not only has a forecast of frigid weather moved the ceremonies indoors, but Mr. Trump has called into question whether Canada still enjoys a place of privilege with its closest neighbour and most important trading partner. This year, however, they will arrive prepared to defend what they already have, armed with facts and statistics to bolster arguments against the imposition of Mr. Trump's threatened 25-per-cent tariffs. Canada's corporate sector has called on Ottawa to play offence when responding to any tariffs. Canada's auto sector is typically held up as a model of industrial integration, but industrial commodities have also been built around seamless border operations. Take Red Dog, the largest zinc mine in the world, which is operated in Alaska by Vancouver-based Teck Resources. Zinc concentrate from the mine is shipped to Trail, B.C. There, it is converted into refined products, including germanium, and sold to customers primarily in the United States.
