THE CANADIAN PRESS/Darren CalabreseCanada-U.S. Trade Minister Dominic LeBlanc is set to travel to Washington this week after United States President Donald Trump threatened to slap new tariffs on an array of Canadian goods starting next month. Brunet did not say exactly when LeBlanc and Charette will be in Washington or identify the officials they are meeting. The continental trade pact has shielded Canada and Mexico from many of the president's tariffs but Trump has repeatedly cast doubt on the agreement's future.
