Doug ford wasted canadian coin on a 75 million dollar ad broadcast in america states and red districts. Specifically an ad calling tariffs a bad idea.
Trump was already looking for an excuse to bail, since he doesn't want to negotiate, he wants to own: and we will never let him. Ford was probably dumb enough that he wasn't aware this was going to trigger trump, so I suspect poilievre told ford to do it so that poilievre had something to drag carney over. Cause I already know the soundbyte from poilievre on the news tonight will be him spouting that carney failed the negotiations.
