Canada's September 8 package matches U.S. tariffs already in force. Trump's separate threat to raise tariffs on Canadian autos, parts and steel to 50% in January remains unresolved.
Canada's Department of Finance formally announced a retaliatory tariff package Tuesday covering C$27.6 billion, or roughly US$20 billion, of American goods, turning a response Ottawa had signaled more than two weeks ago into a fixed September 8 policy.
The package spans about 700 product lines in three tiers: 50% on steel, aluminum, furniture and clothing; 25% on cheese, appliances and some seafood; and 15% on electronics and tools. Ottawa is pairing the tariffs with a C$7.5 billion domestic support package aimed at cash-flow funding for affected businesses and support for workers.
Finance Minister François-Philippe Champagne called it a "dollar-for-dollar, rate for rate" response, saying the counter-tariffs and support package "will protect workers, farmers, families, and businesses."
The important distinction is what Tuesday's announcement answers and what it leaves unresolved. The package matches U.S. tariffs that took effect over the August 21-24 weekend on a range of Canadian goods, including autos, steel, lumber, dairy and electronics. It does not address President Trump's separate statement that tariffs on Canadian cars, trucks, parts and steel would rise to 50% on January 1, 2027, a threat that sent Ford, Stellantis and General Motors shares lower the same day. Canada's retaliation answers the tariff regime already in force. The proposed 2027 escalation remains a separate fight.
The currency reaction was muted. The Canadian dollar traded near C$1.383 per U.S. dollar after the announcement, compared with roughly C$1.386 earlier in the session, a firming of about 0.2%. For a retaliation covering close to US$20 billion in trade, that is a modest move and suggests Tuesday's announcement contained little that surprised currency traders after the prior week's escalation and the tariffs that took effect over the weekend.
Ottawa has now formally matched what the U.S. has already done. Whether Canada will also have to answer what Washington has only threatened is the next stage of the fight.
