I'll start with your first question with respect to the Agreement on Internal Trade Implementation Act. The Canadian free trade agreement replaces the existing agreement on internal trade from 1995, as that legislation is no longer required. As such, the Canadian free trade agreement implementation act will replace the Agreement on Internal Trade Implementation Act, and that's why that repeal is specified in division 10.
On your second question with respect to timber marking, it is a very outdated act from, I think, 1870. It applies to only three provinces. It required that timber being floated down inland rivers be marked.
