From the article: "Prime Minister Justin Trudeau regards Chapter 19 (the dispute mechanism) as the “red line” that Canada will not cross."

That sounds like a perfectly fine stand to take, so well done there, Justin Trudeau.

But my question is this: Which one of his many competent advisors told him that was the best approach to take? And no, I am not prepared to to believe Trudeau reached that stand through his own analysis of the documents...
