Canadian wildfires are driving up the price of wood products that the US construction industry depends on — with knock-on effects on housing. Western Spruce Pine Fir futures were selling for $653 per thousand board feet in late July, not far off last year’s high, and up from a low of $524 in late January. The 937 wildfires threatening forests throughout BC are driving that increase. Alex Strong at the NAHB, said President Trump’s proposed 50% tariff on Canadian goods is adding to uncertainty around the supply chain. Set to take effect Aug. 19, the 50% tariffs would directly apply to Canadian plywood, fiberboard and other wood-derived products used in homebuilding. Canada is one of the top suppliers of fiberboard to the US. Derek Nighbor, CEO of FPAC, said that the country is also America’s third-largest supplier of plywood. …The US Congress Joint Economic Committee warned that Trump’s tariffs on a range of materials could increase building costs by $10,900 per home.
