Trump hits Canadian lumber producers with additional 10 per cent tariffGetting your Trinity Audio player ready...U.S. President Donald Trump has issued new tariffs that could add further pressure on Canadian producers of softwood lumber and furniture. The U.S. has long accused Canada’s softwood lumber sector of violating rules on anti-dumping — flooding a market with cheaper, subsidized products to disrupt a domestic industry. The U.S. Commerce Department announced plans last month to nearly triple duties on Canadian softwood lumber to just over 20 per cent. Lumber Trade Council said that with Canadian producers already facing anti-dumping and countervailing duties of just over 35 per cent, Canadian softwood lumber entering the U.S. will now see total import taxes exceeding 45 per cent. RBC analyst Matthew McKellar said the new levy would heap even more pressure on Canadian lumber producers in an already weak market.
