Canadian Prime Minister Justin Trudeau told a business gathering on Friday that US President Donald Trump’s threat to annex Canada “is a real thing,” two Canadian business leaders who were at the meeting confirmed to CNN.

Prime Minister Justin Trudeau, in a talk with business leaders, said Canada’s wealth of critical minerals are behind Mr. Trump’s comments about making its northern neighbor a U.S. state.

Donald Trump is not joking when he says he'd like to make Canada the 51st state, Prime Minister Justin Trudeau said Friday, adding that the U.S. president's annexation plans are related to Canada's supply of critical minerals.
