Ottawa and Ontario unveil $8.7-billion plan to shield steel, auto and mining from U.S. tariffs

Prime Minister Mark Carney and Ontario Premier Doug Ford on Wednesday announced $8.7 billion in investments and new measures aimed at steel, auto and critical-minerals industries hit by U.S. tariffs, the largest joint federal-provincial response since Canada-U.S. trade talks broke down at the end of August.

Carney called the plan “cooperative federalism in action.” Ford described it as the next step in giving tariff-affected workers certainty and stability.

What is in the package

• Steel: a Joint Steel Action Fund with five-year commitments of $3.55 billion from Ottawa and $1.67 billion from Ontario, to diversify production, serve sectors such as defence and energy, and open overseas markets
• Steel trade protection: Buy Canadian and Buy Ontario procurement priority, tougher Canada Border Services Agency enforcement against dumping, and a Canada-Ontario Steel Task Force focused first on shipping costs
• Autos: up to $2.5 billion over two years ($1.5 billion federal, $1 billion Ontario) for capital projects such as retooling production lines for connected and electric vehicles
• Emissions: greenhouse gas standards for new light-duty vehicles frozen at 2026 levels through the 2029 model year, with annual tightening resuming in 2030
• Critical minerals: Ottawa will match Ontario's initial commitment of up to $1 billion over three years for Ring of Fire roads, plus a coordinated federal-provincial permitting process

The industries at stake

According to the Prime Minister's Office, the auto sector supports more than 120,000 direct jobs and contributes over $16 billion a year to GDP. Steel supports more than 23,000 direct jobs and is integral to 172,000 jobs in fabricated metals. Carney said the combined investments could protect up to 290,000 jobs across Ontario.

The package adds to more than $25 billion in federal tariff support to date, including a $7.5-billion round announced in August that featured liquidity help for small businesses through the Business Development Bank of Canada and extended Employment Insurance flexibilities.

The open questions

Money alone does not restore market access. The steel fund is meant to help producers find buyers beyond the United States, which takes years, not months. It is also unclear how the plan applies to Stelco: a dispute over up to 500 jobs at its Hamilton operations has become a public clash between Ottawa and U.S. parent Cleveland-Cliffs, with Carney threatening legal action, and Stelco's CEO saying federal money could not have prevented the cuts.

The emissions freeze gives automakers flexibility, but it also delays tightening on the road to the 2035 electric-vehicle target, which the government says remains in place. And every dollar here comes as the Parliamentary Budget Office warned a day earlier that federal deficits are widening.

What it means for Canadian investors

For investors, the plan is a reminder of how much policy now drives Canadian industrial stocks. Government support can cushion steelmakers and auto-parts suppliers, but it does not replace a trade agreement, and share prices in these sectors will likely remain sensitive to every headline from Washington. Investors who hold broad Canadian index ETFs already have some exposure through materials and industrials; anyone considering individual companies in these sectors should weigh how dependent their revenue is on U.S. customers. This is general information, not personalized advice.
