Trump, who aides say has little interest in multilateralism, twice attacked Canadian Prime Minister Justin Trudeau on Twitter on Thursday and officials concede the mood is likely to be exceptionally tense.

The Bagotville base was constructed decades ago to protect Canada's crucial aluminum assets, which were used to build US military equipment and vehicles.
The Prime Minister also raised strong concerns about the U.S.'s Section 232 investigation on automobile imports, given the mutually beneficial integration of the Canadian and American auto industries.
Mr Trump's meeting with Mr Trudeau could be particularly frosty, given the president's recent sharp criticism of Canadian trade policies and the anger in Ottawa over Washington's decision to justify its new tariffs on national security grounds.
