I'm also going to speak to part of this.
I think what's important to acknowledge is what we are trying to accomplish with these trade agreements. Multilateral trade can be beneficial, but it cannot come at the cost of a nation state being able to meet the demands and meet the needs of the people within its own nation state.
If negotiating a multilateral agreement prohibits Canada from implementing policy to make sure that certain types of investment are going towards policy objectives that put Canada first, such as feeding our people, such as making sure that people in Canada can make decent incomes working in decent jobs, then I don't think those multilateral agreements are actually of benefit.
