I will be brief.
This agreement ties governments' hands when it comes to environmental policy. We know the Liberal government wants to be very active on that issue. However, there are several mechanisms that limit governments' ability to propose effective environmental measures.
For example, the investor-state arbitration mechanism imposes restrictions and allows corporations to bring actions against a state if its policy does not suit them or if it reduces their profits.
There is also the perspective of the regulatory cooperation mechanism that already requires that states consult their economic opponents or adversaries to see whether certain measures would be restrictive in terms of their desire to do business.
So there are some elements that do really restrict the ability to legislate on environmental issues.
