Canada: The Canada Border Services Agency has started an investigation into gypsum board products being imported from the US. The probe has been initiated by a complaint by CertainTeed Gypsum Canada about the products being imported into British Colombia, Alberta, Saskatchewan and Manitoba, as well as the Yukon and Northwest Territories, according to the Canadian Press newspaper. It is the second complaint that CertainTeed Gypsum Canada has made in recent years, following a similar allegation in 2016.
In 2016 preliminary tariffs were imposed on US imports and then reduced after being blamed for raising the price of wallboard. The increases were linked to higher costs for domestic customers in Fort McMurray, Alberta following destruction caused by wildfires. The Canadian International Trade Tribunal later ruled that US imports had caused injury to local producers but that maintaining duties would not be in the country's trade interests.
