No, that won't be necessary.
In subclause 5(1), it talks about the conveyance, and I imagine that could include trucks. It reads:
the time at which an exported softwood lumber product is considered to be exported is the time at which the product was last loaded aboard a conveyance for export.
So, if a trucker stops for a few moments by the side of the road, that is not the time at which the product was last loaded. And I would emphasize that point.
We are asking that subclause 5(2) specifically include the railways. So, I don't see the relevance of the sub-amendment.
