That's exactly right. That was a very good summary.
I believe that there are two main points to make.
First, despite some progress having been made, such as investor arbitration and other small improvements in environmental protection, when we look at the agreement as a whole, this treaty does not do nearly enough for Canada to meet its climate commitments. In my view, this is a major weakness of this agreement.
Second, there is absolutely no guarantee that certain provisions of the current treaty will not be strengthened once the current U.S. president is no longer in power. At present, there is no process for reviewing, for example, the co-operation of the three parties. There is also no mention of the climate crisis.
Generally speaking, these are major weaknesses.
