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.

Mexico's President Claudia Sheinbaum said on Thursday she and U.S. President-elect Donald Trump had agreed to maintain a good relationship in a friendly phone call that appeared to ease tensions between the top trading partners amid tariff threats.
