Canada is calling it unfair and punitive.
That is the reaction from Natural Resources Minister Jim Carr to the announcement by the Trump administration it will be slapping a 20 per cent duty on Canadian softwood wood.
And the duties would be retroactive dating back 90 days.
The latest volley in the softwood lumber war is not unexpected, but officials say they were surprised by the enthusiasm with which the new U-S government flung itself into the lumber dispute.
