If the online streaming act and the digital services tax move forward, I fully expect action to happen before the 2026 review. I think the Americans will respond.
The two pieces are slightly different. The online streaming act can trigger retaliation associated with the cultural exemption in a way that is different from the digital services tax. We could expect retaliation on the online streaming act any time after it comes into effect. If the Americans want to dispute the digital services tax, they would have to open a chapter 31 case.
Both of these things will complicate the process and result in a full review if they aren't addressed before then.
