The Globe and Mail reports in its Friday edition that U.S. lumber producers are expanding their attack on Canadian exporters by adding New Brunswick to the list of provinces targeted for tariffs. The Globe's Brent Jang writes that a group led by the U.S. Lumber Coalition petitioned the U.S. Department of Commerce in November to challenge what it calls Canada's unfair subsidies for softwood lumber. The Atlantic provinces have escaped U.S. tariffs and quotas over the decades in the long-running softwood dispute dating back to 1982. The strategy to corral New Brunswick is part of the U.S. lumber industry's increasingly aggressive stance in the trade war against Canada, broadening the scope of complaints. "We anticipate 'shock and awe' softwood-lumber duties," RBC analyst Paul Quinn said in a research note. Last month, Commerce Department officials met with representatives from the New Brunswick Lumber Producers and conglomerate J.D. Irving Ltd., the largest softwood producer in the Atlantic region. Four mandatory respondents have been selected by Commerce officials: Resolute Forest Products of Montreal, and three British Columbia producers -- West Fraser Timber, Canfor and Tolko Industries.
