There are several parts to your question.
First of all, with respect to CETA, it's true that the problem is not in the actual wording of the agreement. The problem is that Canada doesn't force Europeans to meet their commitments, in particular with respect to non-tariff barriers. As was mentioned, there's one for wheat and one for beef, for example. I won't list them all because you're no doubt familiar with them. In short, I fully agree.
The world dairy protein market is based on a very low price caused by a surplus of this protein. Supplies are therefore available in Oceania, the United States and Europe at a price that is really below its actual value, and used to make value-added product products like animal feed or baby formula.
However, Canada has trouble selling this protein at a competitive price because of its climate, production costs and the scale of its enterprises. Undertakings that would like to invest in processing this protein should therefore be supported.
Our large-scale dairy processors are prepared to do so, but they hesitate to enter this market because of world competition and everything that I've just explained. Indeed, the major players like Nestlé are very difficult to dislodge from the markets they hold. We should therefore provide assistance to firms prepared to invest in state-of-the-art equipment to process milk protein into value-added products.
