U.S. President Donald Trump, right, extends his hand to Justin Trudeau, Canada's prime minister, during a meeting in the Oval Office of the White House in Washington, D.C., U.S, on Monday, Feb. 13, 2017. Trump's pledge to renegotiate the North American Free Trade Agreement and his support for a "major border tax" threatens to disrupt $541 billion in trade between the two countries, potentially driving up costs and crimping profits for some of Canada's biggest companies including Suncor Energy Inc. and auto parts supplier Magna International Inc.
