The Globe and Mail reports in its Saturday edition that Canadians will soon find out what can be salvaged of North American free trade. The Globe's Tim Shufelt writes that the renegotiation process for the U.S.-Mexico-Canada Agreement, or USMCA, is already effectively under way, which could reshape Canada's economic fortunes for years to come. Many economists believe the odds of both sides walking away are low, but it is not hard to imagine the process going off the rails. President Donald Trump has gone on the attack once again, threatening Canada with devastating tariffs, calling Prime Minister Mark Carney "governor" and toying with the idea of scrapping the "irrelevant" trade deal altogether. Chances are, the USMCA will survive in some form. The practical reasons for its continuation are too extensive to list here. But the end of North American free trade would risk aggravating inflation and job losses in the U.S. in a midterm election year, when the Trump administration is already facing declining approval ratings. "Trump's a deal maker, and he's going to get a deal," said Beata Caranci, chief economist at TD Bank. "It will be favourable to the U.S., but that doesn't mean Canada is going to be the sacrificial lamb."
