Mark Carney, who has become Canada’s new prime minister after Justin Trudeau’s resignation, addressed US President Donald Trump’s proposal to make Canada the 51st state of the United States after taking the oath of office.

Touching upon the major differences between the two countries, Carney said, “We will never and in no way be part of the United States.” He also described US Secretary of State Marco Rubio’s statement that it would be economically better for Canada to be a state of the US as “crazy.”

In response to journalists’ question on whether he would travel to the United States to meet with Trump, Carney said, “I do not plan to travel to the United States. I look forward to speaking with President Trump at the appropriate time.”
