In fact, it is an exemption you will find in the free trade agreement and in the North American Free Trade Agreement. You don't find this concept in the WTO, nor do we find it in the WCT or the WPPT, for example. The cultural exemption is aiming at preserving Canada's sovereignty with respect to some obligations.
For example, if we were to do something that would fall within the scope...if there was an obligation in the NAFTA that would have had an impact on our cultural industry, for example, it would have been possible for Canada not to implement, not to take action with respect to that obligation, for the very reason that we can rely on the cultural exemption.
In the WPPT and WCT, there was no need to have such an exemption in these treaties because they have been crafted in a way that did not require such an exemption in these treaties. First of all, that exemption does not exist in these treaties, and there was no need to seek or to ask for something like this in these treaties.
