Okay, sure.
There's a variety of ways. We have a number of trade agreements with countries that are structured very differently from us, that have different regulatory regimes, and have different levels of development. Often these areas that we're talking about, labour standards or environmental standards, are related to the level of development, so a free trade agreement seeks to set a standard.
Our environment and our labour side accords are now chapters under the CETA and TPP. For example, those are chapters within the FTA. They do a few things. They establish standards for environmental protection or for labour rights, and they provide a mechanism whereby if those standards are not being met, we have recourse. We are able to enforce, against that trading country, their enforcement of their own domestic standards.
