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. While consumer sentiment in the U.S. is starting to fall, our neighbours to the south are simply catching up to the psychology of Canadian consumers, said Greg Hicks, chief executive officer of Canadian Tire. "Consumer sentiment is already really low, lower than it is in the U.S.," Mr. Hicks said. "We just hope that this is more of a transitory period, and cooler heads prevail, and that this is a negotiation [tactic] and we move on. ... I was feeling like the economy was getting to a better place. And so we would hope to get back to that as soon as possible."
