It is true that as soon as a free trade agreement is ratified and implemented, and sometimes even before, we see a decrease in tariff barriers, but an increase in non-tariff barriers. That is the case for Europe as well.
Today, our negotiators and the people who work on these files are working on NAFTA, the TPP, the implementation of CETA, and access to markets in China. If you look at the list, there are currently more than 300 obstacles hindering access to markets. One is inclined to think that we may never solve all of these problems.
I think you would do better to put the question to them directly. We also ask ourselves the same question.
