SYDNEY/LONDON: Global stocks fell on Friday after US President Donald Trump ramped up his tariff war against Canada, leaving Europe squarely in the firing line, sparking a modest investor push into safe havens like gold, while bitcoin hit a new record high. The Canadian dollar fell after Trump issued a letter late on Thursday that stated a 35 percent tariff rate on all imports from Canada would apply from August 1, adding the EU would receive a letter by Friday.
