Canadian Prime Minister Mark Carney announced retaliatory tariffs on the United States in Ottawa after trade talks broke down and new U.S. tariffs took effect on Saturday. The U.S. tariffs cover about $20 billion in Canadian goods, or 5.5 percent of Canadian exports to the United States, including hockey sticks and cement. Canada’s new tariffs will target U.S. steel and dairy and take effect on Sept. 8. Donald Trump hit back on Sunday, while both sides remained at odds over broader trade terms and USMCA revisions.

OTTAWA — Canadian Prime Minister Mark Carney announced retaliatory tariffs on the United States on Saturday, after walking away from a "bad deal" on trade in a deepening rift between the longtime allies.

Negotiations between the neighboring countries broke down Friday in Washington, putting into force new 50-percent U.S. tariffs impacting about $20 billion worth of goods, or 5.5 percent of Canadian exports to the United States.

Impacted products range from hockey sticks to cement.
