A more comprehensive deal has remained elusive.Trump has also stirred anger by repeatedly saying that Canada should become the 51st US state, which Carney has firmly rejected.Those tensions could re-emerge in the coming months as officials set out to renegotiate the terms of the US-Mexico-Canada free trade agreement, also known as the USMCA.
