I think in our current model, and the model that we've proposed to work with Ecuador on, it's careful to balance, as I mentioned earlier, the rights of investors through obligations protections and a mechanism to do that, but with the right to regulate the protection in areas such as the environment, labour, human rights, etc.
We think this model that we have now—much, much different from a 1997 model—strikes that balance.
I'll give you a few examples. We've talked a few times about right to regulate provisions. Those were not in our old model. They are currently, as of CETA going forward, in all of our FTAs across the board, not just on investment.
I talked about balance. We've strengthened substantive provisions, for example, in the investment chapter like expropriation. For example, the mere effect on an investor's investment does not amount to an expropriation. This is something that we've clarified in our provisions that wasn't there in the past.
Third, both parties in a treaty can take reservations to protect their public policy space in areas that they feel need protection. We do that regularly and so do our partners.
