Eugene is the lumber capitol of the U.S.  One would expect an industry spokesperson to give an honest review of the tariff,  and which of the companies in Canada are owned by U.S. lumber producers.  Hedging,  if you will,  their cost of lumber sold from U.S. operations.  

And, of course,  which former Canadian railroads are hauling the lumber.  I have seen,  in the past,  unit trains of lumber on the old SP&S line near Harrisburg,  all Canadian produced lumber.   At it's current pace of cutting,  Canada can never have less standing timber than it has ever had.  Only the age of the stands will be younger,  but sounder,  and more of it merchantable. And that in spite of 28 million acres of recent bug kill.  

Remember,  much less paper demand,  and more paper recycling.  Coos Bay, Gardiner, Lebanon, Albany, Newberg, Salem, West Linn,  Oregon City have lost pulp and paper operations since 1965.
