TORONTO – Incoming U.S. president Donald Trump’s escalating rhetoric around implementing tariffs on Canadian products are sparking worry and disbelief, though some companies are staying quiet. …Trump’s threats show he doesn’t understand how interconnected the Canada-U.S. auto business is, said Flavio Volpe, president of the Automotive Parts Manufacturers’ Association. … Imposing 25 per cent tariffs on auto imports would likely lead to widespread shutdowns in the sector because automakers would be booking substantial losses on every car produced, he said. …Kurt Niquidet, president of the BC Lumber Trade Council, urged in a statement for the U.S. and Canadian governments to find a fair and sustainable solution. …Niquidet emphasized that U.S. consumer demand exceeds what domestic mills can supply and that tariffs would disrupt the supply chain and lead to higher costs for American families. …Companies are generally staying quieter so far. Forestry firms like Canfor and West Fraser declined to comment directly.
