By Promit Mukherjee OTTAWA (Reuters) -Canada will retaliate against President Donald Trump's new tariffs with 25% levies on a raft of U.S. imports, Prime Minister Justin Trudeau said on Saturday, warning Americans that Trump's actions would have real consequences for them.

President Donald Trump signed an order to put tariffs on U.S. neighbors Canada and Mexico, as well as China, starting Tuesday. Canada and Mexico quickly announced retaliatory tariffs, while China said it would take “necessary countermeasures.

Trump’s move to impose new tariffs has bewildered the United States’ closest allies and trading partners, who have vowed to respond with levies of their own.
