The Globe and Mail reports in its Wednesday edition that Canadian softwood producers are bracing for the impact of new U.S. tariffs, warning about economic repercussions on both sides of the border while urging Ottawa to be more aggressive on the lumber file. The Globe's Brent Jang writes the new 10-per-cent tariffs on shipments of softwood lumber from Canada and other countries took effect on Tuesday. President Donald Trump announced the new levies in late September, citing Section 232 of the Trade Expansion Act, which allows him to impose tariffs on the basis of national-security concerns. The Canadian government has repeatedly said it recognizes the crucial role of the country's softwood sector. A joint statement on Tuesday by the leaders of 16 groups in British Columbia urged Ottawa to "bring the same urgency to the lumber file as it has to steel, aluminum and energy." The country's softwood producers will be hit especially hard because the new tariffs have been stacked on top of existing duties on lumber imported into the United States from Canada. U.S. import taxes now total 45.16 per cent on most Canadian producers. B.C. Premier David Eby said Tuesday: "There is no time to wait. Jobs and mills are on the line."
