Green County Home builder Tim Martin said he's worried about a potential 25% tariff on Canadian lumber. President Donald Trump proposed the idea in February and said it could come into effect in April 2025. Trump said he wants t o enforce the tariff because of concerns about illegal immigration and drug trafficking. However, Martin said that this added cost could have a negative impact.Martin is the president of Oklahoma Royal Homes in Claremore. He said a potential rise in Canadian lumber prices could make operations difficult."The reaction is uncertainty, a little bit of anxiety," said Martin. That was how Martin felt about Trump's proposed 25% tariffs. He said this is another hurdle in the already struggling housing market.To find out how this could hurt the wallets of Oklahomans, 2 News reached out to Jason Walter. He's an associate professor of economics at the University of Tulsa."With housing prices it could be anywhere from let's say 5-15% that gets passed through along with the additional cost of aluminum and steel," said Walter. Martin told 2 News they get most of their lumber from local suppliers. However, in rare cases, they buy from Canada, and he says a tariff like this can still affect them.He said the uncertainty left him with questions."Is there going to be a trigger to lessen that tariff over time? I think right now it's uncertainty," said Martin.2 News reached out to the United States International Trade Commission and the US Department of the Treasury but did not get a response from either agency as of March 26.All Martin wants is a better understanding of the future with tariffs."We as business owners really just want clarity and confidence with what's going to happen moving forward," he said.
