The Globe and Mail reports in its Wednesday edition that tariffs have permanently tainted Canada-U.S. relations, according to several prominent Canadian business leaders, who say the country needs a new game plan for a changed world. A triple-bylined item led by Jameson Berkow says that regardless of how long the continental trade war launched by Donald Trump on Tuesday lasts, business leaders warn Canada's economic ties to its southern neighbour will never look the same. Executives are confident the country will eventually be able to diversify away from the U.S., but in the meantime Canadians are likely to suffer substantial economic pain. Louis Vachon, operating partner at private investment firm J.C. Flowers & Co. and former chief executive officer of National Bank of Canada, said recession is a price Canadians should be willing to pay to win a trade war. "I think our freedom is worth a recession," Mr. Vachon said. "Long-term, well, clearly we cannot rely to the same extent that we did before on the U.S. for security and our economic prosperity. That's it. So we need a game plan." Royal Bank CEO Dave McKay said Tuesday that the looming threat of their arrival was already slowing business activity in Canada.
