THUNDER BAY — Northern Ontario businesses are facing another period of trade uncertainty as United States President Donald Trump prepares to impose an additional 50 per cent tariff on a wide range of Canadian products. …For Northern Ontario, the greatest immediate concern is likely to be forestry, wood and paper products and smaller manufacturers selling into the U.S. market. …FedNor says 96% of Ontario’s forestry exports go to the United States. It also identifies 10 Northern Ontario communities where at least 20 per cent of community income is connected to forestry. Ontario’s forest sector supported more than 128,000 direct and indirect jobs provincewide in 2024. …The tariff schedules are product-specific and some forest products are already covered by other U.S. trade measures. …For Northern Ontario sawmills, paper producers and secondary wood manufacturers, the risk comes from both the tariff itself and the uncertainty surrounding it.
