The Trudeau government and regional leaders have put into place a retaliation strategy that's ready to go as leaders call for a national buy-Canadian response to President Donald Trump's tariff plans.

Chrystia Freeland, the former finance minister who is running to replace Justin Trudeau as Canada's prime minister, says her country needs to release a "retaliation list" of goods the country would target if U.

The government is preparing for the possibility that the incoming U.S. administration will impose high tariffs on Canadian goods, setting the close allies up for a showdown.
