But he won't be there forever yet Canada will always be the U.S.' Northern neighbor, biggest trading partner and cultural big brother.
Carney is simply looking elsewhere for friends after being insulted by Trump who treats him like a subordinate and not someone of equal standing. He may even be foolish enough to cozy up to China.
