For Mission businesses enduring the trade war with the United States, uncertainty is the real killer. …A spokesperson for Gill Timbers International, a local timber and lumber exporter, said the trade war is devastating for businesses on both sides of the border. “Businesses can only thrive on certainties,” the spokesperson said. Gill Timbers International estimates that about 90 per cent of its business has been lost during the “ongoing back and forth” between Canada and the United States. Before Trump was elected, the business had a presence inside the U.S. but has needed to scale back and diversify since. … Mission Regional Chamber of Commerce CEO Miriam Bozman said “Mission’s economy is very closely tied to cross-border trade through forestry and wood products, manufacturing, logistics, construction, agriculture. Increased costs, supply chain disruptions, and market uncertainty significantly affect business planning and growth across our community,” Bozman said.
