The Canada-U.S. trade war has entered a broader phase, with Washington targeting Canadian goods in federal procurement while Ottawa pursues a closer economic relationship with Europe.
The latest development came on September 16, 2026, when U.S. President Donald Trump signed a memorandum directing American officials to identify ways to remove or restrict Canadian-origin goods from the U.S. federal civil procurement system.
The move adds government purchasing to an already expanding dispute involving tariffs, retaliatory measures and restrictions on selected goods.

Trade War: What the new U.S. procurement measure does
According to a White House fact sheet, the memorandum directs the Office of Management and Budget, the U.S. Trade Representative and the Federal Acquisition Regulatory Council to work toward making Canadian-origin items unavailable for purchase in federal civil procurement.
The U.S. Trade Representative was also instructed to monitor how Canadian governments treat U.S.-origin goods in their procurement markets.
The White House says the action responds to Canadian procurement preferences, including measures associated with the federal Buy Canadian policy. It also says Canadian companies have had access to more than US$280 billion in the U.S. government procurement system, a figure presented by Washington as evidence of an imbalance.
The memorandum does not itself provide a full product-by-product exclusion list or set a single effective date for every procurement change. Its immediate effect is to begin a process that could make Canadian suppliers less competitive for future federal contracts.
Tariffs remain the central pressure point
The procurement announcement follows Canada’s decision to impose new counter-tariffs on US$20 billion, or C$27.6 billion, worth of U.S. imports beginning September 8.
Canada’s measures include tariff rates of 15, 25 and 50 per cent, depending on the product. Targeted sectors include steel and aluminum, dairy, appliances, agricultural equipment, pulp and paper, plastics and electronics.
In some areas, existing Canadian counter-tariffs increased from 25 per cent to 50 per cent to match U.S. duties. Canada’s official list states that other counter-tariffs, including those affecting U.S. automobiles, remain in place.
The policy creates pressure on companies that rely on cross-border inputs, even when the final product is assembled or sold in Canada. Importers may face higher costs, while exporters must assess whether U.S. customers can absorb additional duties or may seek alternative suppliers, as reflected in Canada’s recent trade figures.
| Date | Development | What it means |
|---|---|---|
| August 25, 2026 | Canada announced new counter-tariffs | Rates of 15, 25 and 50 per cent were set for selected U.S. goods |
| September 8, 2026 | Canadian counter-tariffs took effect | Measures covered about C$27.6 billion in U.S. imports |
| September 16, 2026 | Washington targeted Canadian-origin goods in federal civil procurement | U.S. agencies were directed to develop restrictions on Canadian products |
| September 16, 2026 | Canada and the European Union advanced a deeper partnership proposal | The initiative could expand cooperation beyond existing trade arrangements |
Canada looks to Europe as the dispute widens
The procurement announcement came as Prime Minister Mark Carney was in Strasbourg meeting European Commission President Ursula von der Leyen.
A European Commission address proposed opening the door for Canada to become the European Union’s first associate member. The proposal remains an initiative to be defined rather than a completed membership arrangement.
The European Commission described a future relationship that could build on the Canada-EU Comprehensive Economic and Trade Agreement, known as CETA, while expanding cooperation in defence, critical minerals, batteries, energy, artificial intelligence, quantum technology, cyber security and supply chains.
Von der Leyen said trade in goods between Canada and the EU had grown by 75 per cent in less than a decade under CETA.
Carney’s office said the two sides discussed moving beyond CETA toward a stronger alliance and improving cooperation in strategic capabilities, digital trade, financial services and payments.
The Canadian government has also described trade diversification as a long-term effort to reduce economic dependence on the United States. Its stated objective is to double non-U.S. exports over the next decade, potentially adding C$300 billion in trade.
What Canadian businesses should watch next
The next important question is how quickly the U.S. procurement memorandum becomes a detailed rule affecting contracts, suppliers or product categories.
Businesses selling to American government departments will need to watch guidance from U.S. procurement authorities and the U.S. Trade Representative. Companies with Canadian content in integrated North American supply chains may also need to review how their goods are classified and sourced.
On the Canadian side, federal support programs are being expanded for businesses affected by tariff disruption. The Regional Tariff Response Initiative offers funding for eligible southern Ontario businesses, while broader federal programs include liquidity support, diversification financing and assistance for workers and employers.
The government says an additional C$1.5 billion is being invested through the regional initiative, with eligible businesses able to seek up to C$3 million in non-repayable funding in specified circumstances. Investment measures are also part of the broader response.
For consumers, the immediate effect will vary by product and supply chain. Tariffs do not automatically translate into an identical price increase at the checkout, but they can raise costs for importers, manufacturers, retailers and distributors. Some U.S. imports are subject to the new measures.
The trade war is therefore moving beyond a dispute over border duties. It is increasingly shaping procurement decisions, industrial policy, supply-chain planning and Canada’s search for new commercial partners.
Frequently Asked Questions
What triggered the latest Canada-U.S. trade war escalation?
The latest phase followed Canada’s September 8 counter-tariffs on selected U.S. goods and Washington’s September 16 move to target Canadian-origin goods in U.S. federal civil procurement.
How much do Canada’s new counter-tariffs cover?
The measures cover approximately C$27.6 billion worth of U.S. imports, with rates of 15, 25 or 50 per cent depending on the product.
