Have heard commentators point out the "drop in the bucket" factor to US housing market resulting from increased Cdn lumber. Regardless of whether duties are put on by Can, US or both, a 20% increase in lumber cost is a very minor factor in the overall cost of home starts or reno's in the US. Nice idea, but Can has spent a lot of effort in past rounds of this interminable dispute trying to get US housing / retail lumber market on side without success. Ain't gonna happen.
