U.S. President Donald Trump said he intends to move ahead with punishing tariffs on Canadian and Mexican imports in the coming days despite efforts to convince the administration to back off on measures that would hurt the integrated North American economy.

At a White House news conference with French President Emmanuel Macron, the American President showed no sign he is backing off his threat to impose 25-per-cent tariffs on Canadian and Mexican goods in early March.

“We are on time with the tariffs and it seems like that is moving along very rapidly,” Mr. Trump said when asked if he was going to impose the tariffs.

“We have been treated very badly and it is not just Canada and Mexico. We have been taken advantage of.”
