What’s happened.
On October 21, 2026, the federal government and Ontario announced $8.7 billion in investments and new measures aimed at industries hit by US tariffs. The centrepiece is a Joint Steel Action Fund: $3.55 billion from Ottawa and $1.67 billion from Ontario over five years, about $5.2 billion in total, built on the existing Strategic Response Fund. The stated purpose is to help Canadian steel producers diversify what they make, sell into overseas markets instead of the US, and keep Canadian supply chains stocked with domestic steel for what the governments call nation-building projects.
Alongside the money come rules. Ottawa says it will use the Buy Canadian Policy, and Ontario the Buy Ontario Policy, to put Canadian steel first in public purchasing — including steel for new federal infrastructure, defence work, advanced manufacturing and energy projects. The Canada Border Services Agency will step up monitoring and enforcement against unfairly traded steel imports, and a joint Canada–Ontario Steel Task Force will advise on carrying the measures out, including cutting transportation costs. The auto side gets an extra $2.5 billion over two years for large plant projects, up to $1.5 billion federal and up to $1 billion from Ontario, on top of the $3 billion through the Strategic Response Fund and $100 million through the Regional Tariff Response Initiative announced in February 2026. Carmakers also get breathing room: the fleet average emissions standard stays at the 2026 level of 172 grams per mile through 2029, with annual tightening resuming in the 2030 model year toward 74 grams per mile and a target of 75% electric vehicle sales by 2035.
For minerals, Ottawa committed up to $1 billion over three years to build road access into Northern Ontario’s Ring of Fire, and the two governments will set up a single coordinated permitting process so companies do not file the same approvals twice. They will also name priority Ring of Fire projects that could draw on the Canada Critical Minerals Accelerator, the First and Last Mile Fund and investment tax credits, and create a working group on consultation with First Nations.
What it means for your business.
If you fabricate, machine or supply anything made of steel, the buying rules just moved in your favour, and your marketing has to say so clearly. Public buyers at the federal and Ontario level are now told to prioritize Canadian steel for infrastructure, defence and energy work, so documented Canadian content and mill traceability belong on your capability sheets, quote cover pages and website — not buried in a certificate folder. Auto parts suppliers should note the emissions standard freeze through 2029: it points to steadier near-term orders for conventional vehicle programs, so plan capacity and campaigns around that window rather than a fast electric switchover.
Next step: Before your next public-sector or tier-one bid, assemble written proof of Canadian steel content and put it on the front page of your quote.
