I read the article, I don't take away from it that Canadian lumber is suddenly 50% more expensive. It explains that tariffs for some Canadian lumber products was set to 50 percent at some point (or maybe lowered again, and raised, it's hard to tell since the Trump administration has issued 50+ different tariff directives in the last year), and that Canada walked away from negotiations recently.

I tried to do some more research before my coffee finishes in 5 minutes, you're right it's not ALL Canadian products or even all Canadian lumber products.
