Canada’s government decision to abolish all tariffs on US goods under CUSMA will take effect on 1 September 2025.

Canada’s Prime Minister Mark Carney announced on 22 August 2025 that Canada will eliminate tariffs on US goods covered under the Canada–United States–Mexico Agreement (CUSMA) starting 1 September 2025.

This decision follows the US’s earlier confirmation that Canadian CUSMA-compliant exports will not face tariffs under the International Emergency Economic Powers Act (IEEPA).

On 3 April 2025, Canada announced new countermeasures in response to US tariffs on Canadian goods imposed the previous day by President Donald Trump.

However, Canada will maintain tariffs on steel, aluminium, and automotive products. This follows after Canada’s Department of Finance announced new measures on 19 June 2025 to safeguard steel and aluminium against US tariffs.

Statement by the Prime Minister on Canada-US trade: 

“Throughout our negotiations with the United States on a new trade and security relationship, the objectives of Canada’s new government have been constant:

  • To protect Canadian workers and their families
  • To reinforce the competitiveness of Canadian businesses
  • To build the strongest economy in the G7.

These negotiations have been taking place as the United States has been fundamentally transforming all its trading relationships. This new US trade policy has several motivations: raising tariff revenues, protecting strategic industries, encouraging foreign investment in the US, and changing trade and non-trade policies in US partners.

To these ends, the US has announced a series of trade actions, beginning with International

Emergency Economic Powers Act (IEEPA) tariffs against Canada and Mexico based on US concerns about the border and fentanyl trafficking. This was followed by reciprocal tariffs on every US trade partner, and very high sectoral tariffs applied globally on strategic industries, including steel, aluminium, autos, and copper. The US has also imposed substantial trade actions on the Canadian lumber industry.

In recent weeks, the US has agreed on a series of trade deals with a variety of countries that have several aspects in common:

  • Base line tariffs, covering a broad range of goods, that are substantially higher than those that existed before. The average US tariff rate on the world has jumped from just over 2% at the end of last year to almost 16% currently;
  • Limited or no relief from the sectoral tariffs in strategic industries such as steel and autos;
  • Substantial commitments by US trade partners for investments in the United States; and,
  • Significant unilateral trade liberalisation measures by the US trade partners.

As a result of these developments, the breadth and depth of the changes in US trade policy have become more fully apparent. Specifically, under the new US approach, countries must now ‘buy access to the world’s largest economy’ through tariffs, investments, unilateral trade liberalisation, and policy changes in their home markets.

In previous trade disputes, Canada has implemented a series of retaliatory tariffs. Their objectives have been to protect Canadian workers and businesses and to incentivise a negotiated settlement with the United States. Few other countries have followed suit.

In a positive development, earlier this month, the United States reaffirmed a core commitment to our free trade agreement, Canada-United States-Mexico Agreement (CUSMA), by reinforcing that those Canadian exports to the United States that are compliant with CUSMA will not be subject to US IEEPA tariffs. As a result, the actual US average tariff rate on Canadian goods is 5.6% and remains the lowest among all its trading partners, and more than 85% of Canada-US trade is now tariff-free.

Let’s be clear, Canada currently has the best trade deal with the United States. While it is different from what we had before, it is still better than that of any country. As we work to address outstanding trade issues with the US, it is important we do everything we can to preserve this unique advantage for Canadian workers and their families. Doing so will require both building on a soon-to-be-revised CUSMA and developing a new form of trade and security partnership.

In this context and consistent with Canada’s commitment to CUSMA, I am announcing today that the Canadian government will now match the United States by removing all of Canada’s tariffs on US goods covered explicitly under CUSMA. This decision will take effect on 1 September 2025. In short, Canada and the US have now re-established free trade for the vast majority of our goods.

Canada will retain our tariffs on steel, aluminium and autos as we work intensively with the US to resolve the issues there.  Indeed, our focus now is squarely on these strategic sectors and the future.

The Canadian government will begin our preparations for the CUSMA review process due next year by launching new consultations starting next month to assess Canadian priorities in the new global trade environment.

In addition, following my conversation with the President of the United States yesterday, Canada and the United States will intensify our discussions to address current trade challenges in strategic sectors and to seize major immediate opportunities for trade, investment and security partnerships.

There are many such opportunities. The United States is the world’s largest, most dynamic economy, and Canada is one of its most important commercial partners. Canada is the second-largest foreign investor in the US, and many of our companies are essential to the complex supply chains that drive American competitiveness. Canada is embarking on a transformation of our military and security capabilities to defend Canadians – investments that will create multiple opportunities for new defence and security partnerships.

As we develop our new trade relationship with the US, Canada will continue to take all measures necessary to support Canadian workers, businesses, and consumers.

To address challenges in strategic sectors from agriculture to autos, the Canadian government will soon announce a new comprehensive industrial strategy that protects Canadian jobs, boosts Canadian competitiveness, buys Canadian goods, and diversifies Canadian exports.

In parallel, we are focused on building our strength at home – building Canada strong. The Canadian government will soon select the first in a series of new nation-building projects that will connect and transform our economy. We will catalyse investment and create higher-paying careers through our new Defence Industrial Strategy. We will transform Canadian strategic sectors that are being severely impacted by US Trade. We will double the pace of homebuilding in Canada and create a new housing industry. We will develop new and stronger trade partnerships throughout the world.

For decades, as a result of a series of trade agreements, the Canadian and US economies have become steadily more integrated, continually more deeply connected. As I have emphasised in recent months, that process is now over. As a result, some of our historic strengths have become vulnerabilities.

We can and must adjust to this new reality. That means concentrating on trade, investment and security partnerships that preserve our sovereignty. And it means striking new trade deals that are robust to different economic circumstances and governments because of mutual benefits to both countries.

In all these ways, Canada will move from reliance to resilience: building our strength at home, developing new markets abroad, creating new opportunities for Canadian workers and businesses as we build the strongest economy in the G7.”
