crude petroleum is easily the biggest import from canada at around $124 billion followed by cars and petroleum gas, all which are things on which trump has promised to increase domestic production. although canada is still the country that accounts from the highest percentage of us lumber imports it only represents a fraction of what is produced domestically, and the us has progressively reduced how much lumber it imports from canada: their 2023 imports of lumber from canada reduced to 28.1 million cubic meters, down by around 7%, which would be around $9 billion in total.  on the flipside the us is going to generate around $240 billion of its own lumber this year.  additionally in august this year under biden the u.s. department of commerce already raised tariffs on canadian softwood lumber from 8.05% to 14.54% so perhaps those canucks should get with the program because the us can easily reduce its exports of lumber to cover any domestic demand.
