Hours before the 25 percent tariff on cars made in Canada went into effect, the largest auto plant in Windsor, Ontario, announced it would close for two weeks.

Carney, a former two-time central banker in Canada and the UK, said Trump’s actions will reverberate in Canada and across the world.

Ontario Premier Doug Ford suggested that Canada could drop its tariffs against the United States, stating the northern nation would be willing to take them off “in the next minute” if the U.S. removes its tariffs.

Economist Patrick Anderson says Trump tariffs are like taking "a baseball bat" to auto sales; sees no short-term benefit for Michigan.

Ontario Premier Doug Ford tells Wolf Blitzer what he’s expecting from President Trump’s tariff announcement and explains why he thinks they will be a “tax on Americans.”
