On the negotiation side of it and entering into the agreements, depending on the country, there can sometimes be resistance to the idea of including labour or other types of social considerations in a trade agreement, so we do have to explain our position that, for us and for Canada, there is a linkage between trade and labour, that it's important to ensure that labour rights not be derogated in the interest of benefiting trade, and that we do see linkage and a balance between them.
In terms of the enforcement of it, again in many of the countries we have agreements with, there are capacity issues and that's why as part of our labour co-operation agreements or labour provisions in trade agreements, we have a small technical assistance program that allows us to work with those countries in building capacity and improving labour inspections and promoting knowledge around issues like freedom of association or child labour, for example. It can be a challenge in terms of having the resources, but also in terms of working with both governments and NGOs in those countries, and in building that capacity and that awareness.
