Canada will impose retaliatory tariffs on U.S. imported goods worth C$29.8 billion ($20 billion) effective on Thursday in response to U.S. President Donald Trump's steel and aluminum tariffs, Canada's Finance Minister Dominic LeBlanc said.

Canada's new tariffs are in addition to its 25% counter tariffs on $30 billion Canadian of imports from the US that were put in place on 4 March in response to other Trump import taxes that he’s partially delayed by a month.
