OTTAWA, Aug 25 (Reuters) – Canada hit back on Tuesday with retaliatory tariffs on about $20 billion worth of U.S. annual imports and rolled out aid for businesses and workers, matching Washington’s latest duties dollar-for-dollar.

The counter-tariffs on U.S. goods take effect on September 8 and impose duties of 15%, 25% and 50% across around 700 products imported from south of ​the border, a government statement said.

U.S. President Donald Trump’s new 50% tariffs on US$20 billion of Canadian imports took effect on Saturday after talks between ​the two countries collapsed. The new tit-for-tat tariffs mark a new low in relations between the longtime allies, and ⁠Trump earlier on Tuesday threatened to rename Lake Ontario, which straddles both countries, “Lake America.”
