Experts told us that, in theory, if the US stopped importing crude oil and lumber from Canada and Mexico, it still would be able to meet domestic demand using natural resources available in the U.S. But, in reality, they said, the transition would be costly and take some time to implement, among other complications. “Sure: we could probably meet most of our lumber needs domestically,” said Marc McDill at Penn State University. “The reasons why we don’t boil down to two things: 1) sometimes imports are cheaper than our own suppliers, and 2) we value our forests for a lot of other things.” He added that without lumber from Canada, “1) prices would go up, 2) we would harvest more of our own trees, and 3) we would import more from countries.” …Rhett Jackson at the University of Georgia, said that differences in the lumber produced in the US and Canada may be problematic. …“All lumber is not created equally.”
