The Globe and Mail reports in its Saturday edition that Quebec is bracing for a tariff shock next week. The Globe's Nicolas Van Praet writes that Quebec is a global power in aluminum and aerospace with renewable energy resources and home to several multinationals. But since President Donald Trump was elected, it has also been the biggest Canadian casualty of his protectionist trade agenda. The situation could get much worse if the White House makes good on its threat to levy new 50-per-cent tariffs on $20-billion (U.S.) worth of Canadian exports as scheduled on Aug. 19, including machinery, textiles and furniture. Exporters in the province have already been walloped with 50-per-cent tariffs on primary steel and aluminum and products made from those metals, as well as a 10-per-cent levy on lumber and 25 per cent on upholstered wooden furniture. The U.S. then made changes to those Section 232 tariffs in April to apply duties on the entire value of articles made with steel, aluminum and copper rather than just the specific value of the metal content. That hit a new swath of exporters, including Sea-Doo and Ski-Doo maker BRP. In all, Quebec has an average effective tariff rate of 7 per cent for goods going to the U.S.
