For more information on this question, I would really encourage you to take a look at the work done by Professor Michael Geist. He has done some excellent work on copyright and Canadian cultural content. I think he really points his laser beam focus on the ISDS provisions. It's not necessarily that there is a piece of ruling that says in the TPP that you can or cannot do certain things. It's that we live under a constant fear of being sued if we do try to do things.
For example, Michael Geist said:
The TPP adopts a different approach with exceptions to the cultural exception. That includes limitations on financial contributions for Canadian content development and measures restricting access to online video content. While there is some debate on the full implications of the TPP provision, it seems certain that attempts to expand the Cancon system would be challenged under the agreement.
We would, regardless of whether or not there is a specific clause in the TPP saying you can or cannot do these things, certainly be challenged by our largely American huge media companies south of the border, who don't want to see these policies expanded. I think that's where we recognize that a government that is promoting Canadian culture and that wants to see the expansion of Canadian culture has to come to terms with that.
