The day after threatening to levy additional tariffs on Canadian goods to punish Canada over the wildfire smoke, Trump said he spoke to Carney at the FIFA World Cup final that both of them attended on Sunday. “I have a good relationship with Mark Carney, but we’ve got to stop the fires up there,” Trump told reporters after he returned from the World Cup game in New Jersey.
