Trudeau has appeared on multiple U.S. news networks to warn Canada’s neighbors that their pocketbooks are at risk of becoming collateral damage in Trump’s trade war. “Anything an American president does to hurt the Canadian economy will also hurt American consumers and American workers and American growth,” he told CNN’s Jake Tapper last week.

Canadian PM Justin Trudeau said that if a “worst-case scenario” trade war ensues between the US and Canada, Ottawa won’t hesitate to take strong retaliatory measures.

Canadian Foreign Minister Melanie Joly on Friday announced she would not run in the race to replace Prime Minister Justin Trudeau, saying she wanted to focus on the threat posed by potential U.S. tariffs.
