America Has Tariffs. Canada Has What America Needs.

As Canada-U.S. trade talks break down, Washington may be overlooking an uncomfortable reality: in a world increasingly defined by war, supply-chain insecurity and competition for resources, Canada controls several commodities the United States cannot easily replace.

For decades, Canada has approached its economic relationship with the United States from a fairly predictable position. America is bigger, richer and by far our largest customer, so the assumption has always been that when Washington applies enough pressure, Canada eventually has to compromise.

That assumption may no longer be as reliable as it once was.

The world of 2026 looks very different from the one in which the modern Canada-U.S. trading relationship was built. Conflict with Iran has disrupted energy markets and shipping through the Strait of Hormuz. Russian commodities remain tangled in sanctions and war. Red Sea shipping remains vulnerable. Europe is looking for secure sources of energy and metals, and countries around the world are competing for fertilizer, uranium and critical minerals.

Against that backdrop, Canada's resource wealth suddenly looks much more strategic.

Canada may have a much smaller economy than the United States, but it produces enormous quantities of things America needs: oil, aluminum, potash, uranium, natural gas, electricity and critical minerals. These are not products that can simply be reordered from a different supplier next week. Mines take years to develop. Smelters take years to build. Refineries are designed around specific crude grades. Pipelines run where they run. Agriculture needs fertilizer every growing season.

That is where Canada's leverage begins.

I've spent enough years around sales and business development to know that if one customer represented the overwhelming majority of my business, I wouldn't call that a strong position. I'd call it a risk. Canada has spent decades enjoying the extraordinary advantage of having the world's largest consumer economy next door. In some industries, however, having the United States as our best customer gradually became dangerously close to having it as our only realistic customer.

The current trade fight may finally force Canada to rethink that.

What makes the latest breakdown particularly striking is how close the two countries appeared to be only days ago. A Canadian Press roundup carried by the Toronto Star on August 19 captured a mood that now feels remarkably distant. Prime Minister Mark Carney said Canada was “moving towards an agreement.” President Donald Trump described what was emerging as a “very fair deal for both.” The Canadian Chamber of Commerce was calling for stability, while NDP Leader Avi Lewis warned that “no deal is better than a bad deal.”

Three days later, the talks had collapsed.

That change matters because it suggests this dispute is no longer simply about negotiating percentages on individual tariffs. It is beginning to raise a more fundamental question about the future of the Canada-U.S. economic relationship itself.

Carney hinted at that when he acknowledged that America has changed and that Canada has to strengthen its domestic economy and diversify its trade relationships abroad. That may prove far more consequential than whatever tariff rate is announced this weekend.

Aluminum shows how quickly tariffs can backfire

Aluminum may be the clearest example of why the current U.S. strategy is more complicated than it first appears.

The United States imposed a 50 per cent tariff on imported aluminum, including Canadian aluminum. The theory is easy enough to understand: make imported aluminum more expensive, encourage American production and reduce reliance on foreign supply.

There is nothing inherently unreasonable about wanting more domestic production. The problem is that tariffs can be imposed overnight; aluminum smelters cannot.

A smelter requires billions of dollars in capital, huge and reliable supplies of electricity, specialized infrastructure, environmental approvals and years of construction. Canada already has that capacity, particularly in Quebec, where abundant hydroelectricity supports some of the world's most competitive low-carbon aluminum production.

American manufacturers rely heavily on that metal. It goes into cars, pickup trucks, aircraft, beverage cans, construction materials, machinery, electrical systems and defence products.

Then geopolitics changed the market.

The conflict involving Iran and instability surrounding the Strait of Hormuz tightened global aluminum supplies just as Europe was trying to reduce its reliance on Russian material. European buyers began competing more aggressively for Canadian aluminum, giving Canadian producers something they did not always have in the past: a strong alternative customer.

That creates an uncomfortable outcome for Washington. A tariff designed to pressure Canadian producers can also encourage those producers to sell elsewhere, while American manufacturers still need the metal and may have to pay more to get it.

A tariff does not create aluminum. It changes who pays for it and where the producer decides to sell it.

Consider what that means for an American automaker. A modern vehicle contains large amounts of aluminum and steel, along with copper, electronics, plastics and thousands of components moving through highly integrated North American supply chains. Some of those components cross the Canada-U.S.-Mexico border more than once before a finished vehicle ever reaches the dealership.

Raise the price of aluminum. Raise the price of steel. Add tariffs to imported parts. Increase transportation and energy costs. The automaker can absorb some through lower profits and suppliers can absorb some through reduced margins, but eventually part of that cost reaches the buyer.

You don't need an economics degree to understand that. If it costs more to build the truck, somebody eventually pays more for the truck.

That is the weakness in the argument that tariffs are simply taxes paid by foreign countries. They aren't. The importer writes the cheque at the border. Foreign suppliers may absorb some of the cost, and American companies may accept smaller margins, but a meaningful share can ultimately work its way into the cost of vehicles, appliances, construction, machinery, transportation and food.

American manufacturers do not become more competitive simply because their higher input costs have the word “tariff” attached to them.

Oil is the card nobody should want Canada to play

If aluminum demonstrates the problem with tariffs, oil demonstrates the extent of Canada's underlying leverage.

Canada supplies roughly 3.9 million barrels of crude oil to the United States every day, or about 1.4 billion barrels a year. It is by far America's largest foreign source of crude, and in parts of the Midwest the dependency is considerably greater.

The grade of that oil matters. Much of America's shale production is lighter crude, while many Midwest and Gulf Coast refineries were designed or substantially modified to process heavier grades like those produced in Western Canada. Replacing millions of barrels of Canadian heavy crude is therefore not as simple as telling Texas to drill another well.

You need the right type of crude, delivered to the right refinery, through the right infrastructure, at the right price.

Now consider the state of the world.

The Strait of Hormuz has historically handled roughly one-fifth of global oil flows. When shipping through that corridor is threatened, insurers react, tanker traffic slows, prices rise and governments start thinking less about the cheapest possible barrel and more about the safest possible barrel.

Canadian crude doesn't have to sail past Iran. It doesn't need to travel through the Persian Gulf or Red Sea. It doesn't require naval escorts to reach the American market. Much of it moves through pipelines across one of the most stable borders in the world.

At a moment when Washington is concerned about global energy security, it is also escalating a trade dispute with its safest and largest foreign crude supplier.

In business terms, it reminds me of getting into an argument with your most dependable supplier while several of your other suppliers are stuck behind a shipping blockade. You can do it. I'm just not sure I'd call it good purchasing strategy.

Canada should not shut off oil exports to the United States. Doing so would hurt Alberta, Canadian producers, government revenues and ultimately Canadian consumers. It would also invite serious American retaliation.

But Washington should understand that the leverage exists.

At current export volumes, an effective US$10-per-barrel increase on roughly 3.9 million barrels a day represents about US$14 billion annually in gross additional cost across the supply chain. At US$20 per barrel, the figure approaches US$28 billion.

That is not the same as saying American consumers would simply receive a US$28-billion bill. Canadian producers could absorb some through lower prices, refiners could absorb some through margins and markets would adjust. But adding another major energy disruption while Hormuz is already under pressure would inevitably work its way through gasoline, diesel, jet fuel, trucking, agriculture, chemicals and inflation.

That is why oil is probably more valuable to Canada as a last-resort bargaining chip than as an actual weapon.

There is also a legal obstacle. Under CUSMA, Canada generally cannot simply impose a discriminatory export tax solely on goods headed to the United States without applying a comparable charge domestically. Ottawa could explore broader resource charges or other trade measures, but a straightforward U.S.-only oil export tax would almost certainly trigger a major dispute.

The fact that it would be legally difficult, however, does not mean the underlying economic leverage is imaginary.

Potash may be the smarter pressure point

Oil attracts attention. Potash may be strategically even more interesting.

Potash supplies potassium, one of the three essential nutrients required for modern agriculture. American farmers need it every year, and the United States imports the overwhelming majority of what it consumes. Canada supplies most of those imports and is the world's dominant potash exporter.

The geopolitical alternatives are not especially attractive. Russia and Belarus are major global producers, which means that if Washington deliberately makes Canadian fertilizer more expensive or less available, it risks becoming more dependent on countries with which it has far more complicated relationships.

Canada, meanwhile, already has customers around the world. Brazil buys Canadian potash. China buys Canadian potash. Other major agricultural economies do too.

That is what makes potash particularly interesting as leverage. American farmers need fertilizer every season. Canada has fertilizer and a planet full of farmers.

It would not be painless for Saskatchewan producers to redirect huge volumes away from the United States, nor would it happen immediately. But there is a global market, and having other buyers matters.

The same principle applies far beyond potash. Canada has uranium, critical minerals, natural gas, hydroelectricity and a growing ability to move energy and commodities toward markets other than the United States.

That may ultimately be the real answer to this trade confrontation.

Canada does not need to shut anything off. It needs to make sure it has somewhere else to sell it.

The Trans Mountain Expansion gives Western Canadian crude greater access to Pacific markets. Canadian aluminum is attracting European buyers. Potash is already global. LNG creates another path. So do uranium, critical minerals and processed metals.

Every additional port terminal, pipeline, LNG facility, mineral-processing plant and long-term European or Asian supply agreement reduces Canada's dependence on one customer.

I've always believed in a fairly simple business rule: the best time to find a second customer is before the first customer realizes you need them more than they need you.

Canada may be learning that lesson later than it should have, but late is better than never.

That is also why it is becoming increasingly difficult to argue that the current tariff strategy is achieving all of its stated objectives.

Tariffs can protect certain domestic producers and can encourage investment over time. That argument is legitimate. But there is an enormous difference between encouraging an aluminum smelter to be built over the next decade and replacing millions of tonnes of Canadian supply next month.

A tariff can be imposed tonight. A mine cannot be developed tonight. A refinery cannot be redesigned tonight. A smelter cannot be built tonight. A continental supply chain cannot be recreated tonight.

American businesses and consumers pay today's costs while policymakers wait for tomorrow's factories.

And there is another unintended consequence. If the purpose of pressure is to make Canada more dependent on the U.S. market, then encouraging Canadian companies to find European and Asian customers produces precisely the opposite result.

Global instability only strengthens that trend.

The world is becoming less predictable. Iran, Hormuz, Ukraine, Russia, the Red Sea, China, food security, energy security and critical-mineral security have changed the way governments and companies think about supply chains.

For years, price was king. Increasingly, reliability matters too.

Where does the oil come from? Can the tanker get through? Could sanctions interrupt supply? Where will next year's fertilizer come from? Is the exporting country politically stable? Is the trade route secure?

Canada scores remarkably well on those questions.

It has enormous natural resources, stable institutions, the rule of law, Atlantic and Pacific access, vast hydroelectric capacity, railways, highways, pipelines and direct physical access to the largest economy in the world.

For a long time, Canada may have undervalued those advantages because selling south was so easy.

The rest of the world increasingly does not.

None of this means Canada would somehow “win” an unrestricted trade war with the United States. It would not. The American economy is many times larger, and Canadian businesses and workers would suffer enormously in a prolonged confrontation.

But Canada does not need to defeat America.

It only needs to change the calculation in Washington.

If Midwest refiners become nervous about crude supply, American farmers worry about fertilizer costs, manufacturers pay substantially more for aluminum and Canadian producers begin signing long-term agreements elsewhere, pressure starts to come from inside the United States itself.

From manufacturers. From farmers. From refiners. From governors. From consumers.

At that point, Ottawa is no longer the only one making the argument.

That may be Canada's real advantage in this moment: not size, but scarcity, geography, reliability and options.

The United States should remain Canada's largest and most important trading partner. The two economies have created enormous prosperity together, and there is no rational future in which that relationship becomes unimportant.

But partnership and dependency are not the same thing.

Canada should absolutely want America to remain its best customer. It should simply make certain that America is never again its only realistic customer.

Only days ago, politicians on both sides were speaking as though a deal was within reach. Today the negotiations have collapsed and the conversation has moved from tariff percentages to something much larger: what kind of economic relationship do these two countries actually want?

Perhaps that uncertainty will finally force Canada to do something it should have done years ago — build enough pipelines, ports, export infrastructure and international commercial relationships that no single foreign government can determine our economic future.

America has the bigger economy.

But the world needs secure energy, and Canada has it. The world needs aluminum, fertilizer, uranium and critical minerals, and Canada has those too.

As the world becomes less stable, reliable suppliers become more valuable.

The question is no longer whether Canada has leverage. It does.

The real question is whether Canada finally has the confidence — and the long-term strategy — to use it intelligently.
