I can't answer on exactly what the Canadian government's model is for free trade agreements. I know the NAFTA has been used. My understanding is that the free trade agreement with Chile, although I haven't looked at it recently, is not that far off. The NAFTA model was the model for Mexico's negotiation with the European Union. So a lot of people think the NAFTA model, in certain respects, was very forward-thinking.
