There is a de facto difference, in that member countries of NATO are generally considered a lower risk by our government and are not necessarily governed by the same framework. However, you will notice that Turkey is not on that list of low-risk countries. In fact, Turkey's status is that it is not on any list. We can add the fact that Turkey and other countries are on the Export Development Canada list, but they are designated as countries “open on restricted basis”, precisely because of those issues.
Generally, it is easier to sell systems for military use or for dual use to countries that are part of an alliance like NATO, which already has mechanisms that work well, or to allies like the countries in the Five Eyes, for example, with whom we have excellent relations.
