I have some experience with this because the first trade agreement that we started getting into labour and environment issues was the North American Free Trade Agreement, where it was done in side agreements rather than in the main body of the agreement. I think since that time you can see a considerable amount of progress in putting in disciplines, which have more teeth in them, in terms of both labour and environment—on labour, for instance, referencing the need to respect a number of the international labour agreements, and then, of course, for each country to be respecting the implementation of its own laws.
One important feature of the TPP as compared with the NAFTA is that the dispute-settlement provisions of the agreement itself apply to those areas of the agreement. That's not the case in the NAFTA. The side agreements had their own separate provisions.
I think this is moving in the direction of making it less likely that other countries are going to be able to engage in unfair practices in either labour or environment, to try to steal business from Canada.
