Canada has unveiled a series of counter tariffs on US goods as a growing trade war between Ottawa and Washington ramps up.

In a press conference on Tuesday, Finance Minister François-Philippe Champagne said Canada would respond to newly imposed US duties in a "proportionate, targeted, and strategic way," matching Washington's levies "dollar for dollar, rate for rate."

"Effective September 8, Canada will impose counter tariffs of up to 15, 25, or 50% on C$27.6 billion in imports from the United States of America," he said.

The move comes after hefty 50% US duties impacting around C$28 billion (€17 billion) worth of Canadian goods came into effect on Saturday, following a break down in trade talks between the two countries.

The US tariffs affect products ranging from hockey sticks to wine to cement.
