VANCOUVER (CP) - Canada's lumber industry is talking to its American counterpart and to provincial governments about amending the Canada-U.S. Softwood Lumber Agreement, despite federal insistence that negotiations are over, sources say.

The U.S. Coalition for Fair Lumber Imports, the influential industry lobby behind punitive tariffs on Canadian lumber, this week categorically denied that it or its members were discussing changes to the softwood deal initialled July 1.

But Canadian industry sources told The Canadian Press on Thursday that informal contacts did take place between individual lumber executives on both sides of the border.
