Trump announced on Truth Social Tuesday he would impose an additional 25% tariff on steel and aluminum imports for Canada—on top of the 25% already planned for global steel and aluminum—in retaliation for Ontario’s 25% charge on electricity imports.

In response to Ontario imposing a new tax on electricity supplied to three U.S. states, President Trump said he wants to double steel and aluminum tariffs on Canada.

President Donald Trump backed down from an extraordinary trade war escalation Tuesday that had threatened a massive surge in Canadian steel and aluminum tariffs and new tariffs on Canadian electricity.
