This has been going on for the last twenty years. There is a fundamental difference on privatly owned timber land as in the U.S. and "Crown" land, provincially owned land in Canada. The largest lobbiests are from the southern states. These land owners used to grow cotton. The US textile industry no longer received the protection from off-shore competition and the cotton growers became Yellow Pine growers. The US has mismanged it's fiber supply really wants Canadian raw logs. If the US lumber manufactures could by the raw logs for the same price as the canadian manufactures could they would be entering the US with-out any duty.
