Trudeau is simultaneously warning that the American president is after Canada's large finds of critical raw materials, reports, among others, the public service company CBC.
Trump has in mind that the easiest way to do it is to absorb our country, and that's for real, said Trudeau to a group of business leaders, without knowing that a microphone was still on.
Trump has several times said that he wants Canada to become the "51st state of the USA" and simultaneously threatened the neighboring country with trade war in the form of heavy tariffs.
Trudeau made his comment right after his opening speech at a conference on economic cooperation between Canada and the USA on Friday, where he described the country's challenges regarding the trade relationship with the USA.
After the opening speech, journalists were driven out of the room, but the microphone that was left in the room had not been turned off.
Trump decided on tariffs of 25 percent for both Canada and Mexico last week. But after talks with Trudeau and Mexico's President Claudia Sheinbaum, Trump decided to postpone the trade war for 30 days in exchange for promises of strengthened border surveillance.
