The United States and Canada have repeatedly come close to a full-scale trade war since President Donald Trump returned to office. Trump has often stepped back from some of his strongest threats against Canada, but that period of relative calm has now ended.

New 50% US tariffs on certain Canadian goods took effect on Saturday, pushing the two countries closer to a possible tit-for-tat trade fight. Canada has threatened to respond with its own tariffs, raising fears that the dispute could hurt the US economy.

Canada tariffs could hurt US businesses

The new tariffs cover only a small part of the overall trade between the US and Canada. But economists warn that the impact could grow quickly if Canada retaliates and the Trump administration responds with even more tariffs. “The bigger deal is uncertainty,” said Scott Lincicome, vice president of general economics at the Cato Institute, according to the New York Times.

Lincicome said changing tariffs has already created uncertainty throughout Trump's second term. Tariffs have been raised and lowered quickly, creating problems for Wall Street, US allies and American businesses. This uncertainty can make companies more careful about spending and investing because they do not know what trade costs will look like in the future.

US tariffs can raise prices

Tariffs are essentially taxes placed on imported goods. While foreign exporters may absorb some of the cost, US importers can also end up paying more. Those higher costs can then be passed on to American businesses and consumers through higher prices. The latest 50% tariffs cover about $20 billion worth of Canadian exports to the US, according to administration officials.

The list includes hundreds of products, such as hockey sticks, furniture and dairy products. If these goods become more expensive to import, US companies that rely on Canadian products could face higher costs.

Canada trade war impact may grow

The limited size of the tariffs means the immediate impact on the overall US economy may be relatively small. John Ricco, deputy director of policy analysis at the Yale Budget Lab, estimated that the new measures would push the average tariff rate on Canadian imports to about 7.6%, from roughly 5.3%, according to the New York Times.

The US already has high tariffs on some important Canadian products, including lumber, steel and cars. However, the latest tariffs are different because they do not provide a special exemption for goods covered by the existing US-Mexico-Canada trade agreement. Trump has separately said he wants to revise or potentially end that agreement.

Canada could hit US industries in retaliation

The biggest economic risk could come if Canada responds with tariffs of its own. Canadian Prime Minister Mark Carney said Canada could announce new tariff measures shortly after Labor Day. The planned response could target US agriculture, steel and electronics, according to the New York Times.

Carney also warned that Canada was prepared to fight back, at one point describing the situation as a “war.” If both countries continue increasing tariffs, businesses on both sides of the border could face rapidly rising costs.

US auto industry faces risk

Joe Brusuelas, chief economist at RSM US, said Canada could target areas where the US would feel the most pain, according to the New York Times. One possible target is the US auto industry. The auto sector has close supply-chain links between the US and Canada, meaning tariffs can increase costs for companies that operate across the border.

Higher costs could eventually put more pressure on prices. Brusuelas warned that this could create new inflation risks at a time when US manufacturing is already struggling.

Canada tariffs could worsen inflation

Another round of tariffs could make it harder for the US to bring inflation down. US inflation remains above the Federal Reserve's 2% target, despite Trump's arguments that his policies are not driving prices higher. Rising prices have already forced the administration to make some changes to its tariff policies.

Earlier this week, Trump relaxed tariffs on beef imports as beef prices increased. That move showed how trade policies can affect what Americans pay for everyday goods.

Higher prices could eventually hit American consumers

If US importers pay more because of tariffs, companies may pass those costs on to consumers. That could make products imported from Canada more expensive. Even businesses that do not directly import Canadian goods could be affected if Canadian tariffs disrupt supply chains or increase the cost of materials. For consumers, the result could be higher prices at a time when Americans are already dealing with elevated living costs.

Tariffs could slow US investment

The impact would not only be about prices. Lincicome said prolonged uncertainty and retaliatory tariffs could lead to “slightly less investment, slightly less economic activity.” Companies may delay expansion plans, hiring or other spending when they cannot predict future trade costs. Businesses that operate on both sides of the US-Canada border could be particularly exposed to the uncertainty.

The potential Canada trade war is happening at a difficult time for the US economy. America's federal debt reached $40 trillion this week, increasing concerns about the country's financial position. Those debt concerns have contributed to higher government bond yields.

At the same time, the war with Iran has created additional economic problems, including weaker global growth and higher fuel costs. A new trade conflict with Canada could therefore add another shock to an economy already dealing with several challenges.

Trade uncertainty has increasingly spilled into financial markets during Trump's second term. Investors have had to respond to frequent changes in tariff policy. A prolonged dispute with Canada could create more uncertainty for companies, investors and financial markets. The concern is not simply whether tariffs raise prices, but whether another round of trade tensions could slow economic growth.

US lawmakers warn of economic damage

Some Democrats in Congress have warned that Trump's threats against Canada could hurt American businesses and workers. Senator Peter Welch, Democrat from Vermont, called the new tariffs a “slap in the face” to farmers and others in his state who do business across the border, according to the New York Times. Welch said business relationships built between the US and Canada over decades were now facing uncertainty. He also said long-term negotiations over a trade deal appeared to be on hold.

The situation could still change if Washington and Ottawa reach a new agreement. Brusuelas said he still believes a deal is possible, meaning the trade war does not necessarily have to escalate. But he also warned that the risks of further escalation are real and could become costly for the US economy.

US Trade Representative Jamieson Greer said there were no new talks planned with Canadian officials and that the Trump administration was moving ahead with its tariffs, according to the New York Times. That made an immediate breakthrough appear less likely.

Why this matters for the US economy

The direct economic impact of the latest tariffs may be limited because they cover only a small portion of US-Canada trade. The bigger threat is what happens next. If Canada retaliates and the US responds again, tariffs could spread to more industries and products.

That could push up prices, increase costs for businesses, slow investment and put more pressure on US economic growth. The dispute also comes when inflation remains above the Fed's target and the US economy is already facing pressure from high debt, elevated fuel costs and weak manufacturing.

For now, the Canada tariffs are not large enough to create a major shock to the entire US economy. But a prolonged cycle of tariffs and retaliation could have a much wider impact.

The key risk is that companies and consumers face higher prices and greater uncertainty at the same time. As Brusuelas put it, markets and businesses have become accustomed to Trump's negotiating strategy, where threats and tariff changes are followed by negotiations. The concern for the US economy is whether that pattern continues with Canada — or turns into a prolonged trade war.
