Donald Trump's second administration is filling up with some of his most loyal supporters and many of the people landing top jobs have been critical of Prime Minister Justin Trudeau and security at Canada's border.

Prime Minister Justin Trudeau sounded an upbeat note Tuesday on the prospect of working with U.S. president-elect Donald Trump, saying Canada has dealt with his trade threats before and can do so again.

The potential consequences include trade disputes that push Canada into recession since 75% of its exports go to the U.S.

Trump's designations for foreign policy and border positions have sent signals to Canada, and the rest of the world, about America's path forward.
