Major concerns are being expressed on both sides of the border regarding the higher US duties on Canada’s softwood lumber. …The current 35.19% duty, along with any steeper tariff, is detrimental to US homebuilders and homebuyers longer term, warns Rose Quint, of NAHB Survey Research. Higher mortgage rates of 6% to 7% since 2022 have already weakened housing demand and caused lumber prices to edge downwards. The real effect of tariffs might be delayed by wholesalers having stocked up building materials earlier in the year to avoid higher tariffs “Years of building above and beyond our traditional baseline is required to make up the 1.5 million deficit that we have in new housing units,” Quint adds. …Affordability challenges already existed and will be further worsened by the higher costs. …The overriding hope among the Canadian producers and American homebuilders is that a suitable agreement will be reached between the US and Canada.
