Canadian trade representatives have arrived in Washington for more talks amid a tentative trade deal with the US. …Canada and the US now have until Saturday to reach a deal. …Multiple sources say there are reductions in sectoral tariffs, such as steel and aluminum, as part of the agreement with the US, but none of the sources knew the scope of those reductions. …It’s still unclear how softwood lumber will be treated in ongoing trade negotiations, according to an industry expert. But Derek Nighbor, CEO of Forest Products Association of Canada says that he’s “optimistic.” …Ideally, Sections 338 and 232 which impact the industry would be eliminated, he said. “If we can see those tariffs go away and if we can get a commitment to see Canada and the US get back to the table to negotiate an agreement on softwood, I think that would be a pretty good outcome,” he said.
