Carney is wrong, but he's not a fool. I read this as high-level virtue signalling to two audiences: Canadian left-patriots, who love to hate America while (unknowingly) free-riding on the benefits of the relationship. He has a vulnerable majority and is smart enough to plan ahead for the next election. Over half of Boomers support the Liberals, so he is playing to their emotions. He doesn't need to play to their pocket books, because they're mostly as rich as they're going to get, so he can trade economics for votes.
Second: he's signalling to China, and other international trade partners, that we are open for business. Carney has been struggling with pro-China (former) members of his caucus also being pro-slave-labour[0]. This is a message that, as he indicated in his Davos speech[1], he is willing to be flexible on Human Rights if the price is right.
America hasn't changed. When Trump is gone the American export market will remain.
Carney is wrong, but he's not a fool. He's amoral.
