No, I don't think they are, simply because most other countries at the WTO have sensitive products as well.
In fact, I mentioned the EU's pork access earlier as an example. They have no intentions of providing better market access for pork. They know that their over-quota tariffs are high enough that they can reduce them significantly. They want to make sure they don't have to expand the 0.5% minimum market access that they provide on pork. So they will fight very hard to do exactly this.
It really has to do with different countries wanting to provide market access for their sensitive products in different ways. For example, Canada is willing to go to zero within quota tariffs. Some countries have very high in-quota tariffs, and in fact some of the countries prepared to expand their TRQs have high enough in-quota tariffs that there will be no better market access, as you know. Other countries are willing to say they would be prepared to reduce their over-quota tariffs, but you know these countries have enough room that they can reduce them without actually providing better market access.
In the past, Canada has shown that it is quite willing to give a clear 5% minimum market access without in-quota tariffs, and it is prepared to continue with those TRQ commitments. So while different countries want to provide market access in different ways, different countries suggest ways of improving market access that won't actually improve market access. For that reason, Canada isn't isolated in that regard, and in fact I think has been exemplary in the way it has suggested that market access for sensitive products should be improved. Canada has also been exemplary in suggesting that there should be aggressive tariff reductions in the tariff reduction category, and I believe it has shown a lot of leadership in the negotiations on domestic support.
