Another wave of American duties is expected to hit Canada's softwood lumber industry

Another wave of American duties is expected to hit Canada's softwood lumber industry Monday, putting pressure on smaller producers to cut jobs.

Washington announced preliminary countervailing duties in April against five companies ranging between three and 24 per cent.

This time, the Trump Administration is expected to announce preliminary anti-dumping duties at the average rate of 10 per cent, to be tacked on to the previous levy.

The ripple effects of the first round of duties are already being felt.

Resolute Forest Products has cut shifts at seven sawmills, and there are fears others will follow suit.
