Ottawa is hitting back against the United States with hefty counter-tariffs on $27.6-billion worth of American products including metals, seafood, clothing, home appliances and electronic devices.

On Tuesday morning, the federal government outlined how it plans to retaliate against the new 50-per-cent tariffs U.S. President Donald Trump placed on around $28-billion worth of Canadian goods over the weekend after trade talks collapsed late Friday.

Ottawa is targeting more than 700 items, with most of the levies set at 25 per cent or 50 per cent, with a small number subject to a lower 15-per-cent tariff. The tariffs are scheduled to come into force on Sept. 8.

Ottawa also outlined a $7.5-billion support package of “new and enhanced” measures Tuesday for Canadian workers and businesses affected by the latest wave of American tariffs. The Canadian measures include easier access to Employment Insurance for affected workers and a range of loan programs for businesses.

“When the United States asked too much and offered too little, we chose to stand up for Canadians,” Finance Minister François-Philippe Champagne said in a statement.

“Our dollar-for-dollar, rate for rate counter-tariffs as well as a multi-billion dollar support package will protect workers, farmers, families, and businesses as we build a stronger, more resilient, and more diversified Canadian economy.”
