Trade talks between the United States and Canada have stalled, and Canada's government says it will respond with its own tariffs on U.S. goods starting September 8.
Canadian Prime Minister Mark Carney announced the move after negotiations aimed at resolving an ongoing tariff dispute between the two countries did not produce an agreement. The announcement means a new round of counter tariffs will take effect on a range of American products shipped into Canada, adding to tariff measures that have been building between the two economies over the past year.
The United States and Canada have one of the largest trading relationships in the world, with goods and services crossing the border worth hundreds of billions of dollars each year, spanning everything from autos and machinery to energy and agriculture. Disruptions to that relationship tend to ripple through supply chains on both sides of the border, and businesses that rely on cross border trade have been watching the talks closely for signs of when normal terms might resume.
For now, both governments appear to be preparing for tariffs to stay in place for some time rather than for a quick resolution. Companies with cross border supply chains are expected to face higher costs on affected goods once the September 8 tariffs take effect, and some of that cost is likely to be passed on to consumers in both countries.
Watch for the specific list of goods covered by Canada's September 8 tariffs, and for whether either government signals a path back to the negotiating table in the days ahead.
