Canadian Prime Minister Justin Trudeau says he had an “excellent conversation” with Donald Trump in Florida after the president-elect’s threat to impose significant tariffs on two of America’s leading trade partners raised alarms in Ottawa and Mexico City.

The leaders of Mexico and Canada responded quickly, and in different ways. Justin Trudeau, Canada’s prime minister, jumped on the phone to Mr Trump to chat about the “intense and effective connections” between their countries. His deputy, Chrystia Freeland, released a statement about the importance of border security.
