trade courts did not find the US complaints legitimate, and repeatedly rule in canada's favour. the end root of the difference in cost is that canada is really big with a lot of forest and doesnt have better things to do with forested land.

the logs in canada are just worth less than the ones in the US. Differential advantage is a real thing that exists.

If the US government really beleives it to be a canadian government subsidy to loggers, it should be more than happy to give the tariff money to the canadian government, making canada's taxes and fees exactly what the US thinks they should be.
