The tightly-intertwined US and Canadian auto manufacturing industry could grind to a halt in as little as 10 days due to US tariffs, according to Ontario premier Doug Ford.
Raw materials and partially assembled vehicle components can cross the US-Canadian border between manufacturing plants as many as eight times before becoming a finished vehicle, Ford said today. But the 25pc tariffs the US imposed on most Canadian and Mexican goods effective today will add costs and disrupt supply chains.
Canada and the US could have combined efforts to make the two countries the safest and secure, Ford said, but "... unfortunately, one man, president Trump has chosen chaos instead."
Ontario, Canada's largest province by population and a major vehicle manufacturing hub, may also cut nickel exports to the US, Ford said, and may put a 25pc surcharge onto electricity flows into New York, Minnesota and Michigan if the tariffs persist. Canada supplied about 46pc of US nickel from 2019-2022 according to the US Geological Survey, and nearly 36TWh of electric power to the US.
Ontario is also banning US companies from government contracts, including cancelling a $100mn contract with Elon Musk's Starlink internet services. Ford also directed the Liquor Control Board of Ontario (LCBO) to remove US products from its store shelves, meaning other retailers, bars and restaurants will also be unable to restock American goods. The LCBO is the largest purchaser of alcohol in the world, according to Ford, selling nearly C$1bn in products, including 3,600 products from 35 US states.
Ontario's action comes after Prime Minister Justin Trudeau announced Canada's retaliation of 25pc tariffs on $30bn of US imports, followed by another $125bn of imports in 21 days' time.
Canadian energy exports to the US are subject to a lower 10pc tariff. Alberta premier Danielle Smith called the US tariffs "both foolish and a failure in every regard." She called on her Canadian peers to fast-track the construction of dozens of resource projects to help relieve the country's dependence on the US for sales.
