The rapidly escalating US-Canada trade dispute is moving beyond tariffs. With Ontario threatening restrictions on electricity exports and Ottawa preparing dollar-for-dollar retaliation, the confrontation highlights how deeply integrated the two economies have become — and how quickly trade dependence can become geopolitical leverage.

Ontario Premier Doug Ford has threatened to restrict electricity and critical mineral supplies to the United States if President Donald Trump continues escalating his trade confrontation with Canada.
The warning followed Trump's announcement that US tariffs on Canadian cars, trucks, automotive parts and steel would rise to 50% from January 1, 2027. According to RT, the announcement came after trade negotiations collapsed last week and followed a separate 50% tariff imposed on approximately $20 billion of Canadian imports.
Ford said Ontario was prepared to retaliate.
“Everything’s on the table. I’ll do whatever it takes.”
Ontario currently supplies electricity sufficient to power around 1.5 million American homes and businesses, according to Ford. He warned that the province could increase electricity prices or halt exports altogether if Washington continued measures he believes threaten Canada's manufacturing sector.
Trump Tells Canada to “Fall in Line”
Trump responded through Truth Social, dismissing Ford's threat as “bluster” and warning Canadian leaders to “fall in line.”
He also again referred to Canadian Prime Minister Mark Carney as “Governor Carney” and argued that Canada's economic dependence on the United States meant it could not survive without its southern neighbour.
Ford responded in equally blunt terms, showing how rapidly the disagreement has moved beyond conventional diplomatic language.
More importantly, however, Ford suggested Canada could broaden its retaliation beyond electricity. Oil, potash and strategic minerals could potentially become part of Canada's response if the dispute continues.
Quebec Premier Christine Frechette has not adopted Ford's electricity strategy but reportedly said she would not rule it out as Canada enters what she described as a “new phase” of the dispute.
How Much Does America Depend on Canadian Electricity?
The national numbers initially make Canada's electricity threat appear relatively modest.
According to US Energy Information Administration figures cited by RT, the United States imported approximately 24.5 terawatt-hours of Canadian electricity during 2025, while exporting around 16 terawatt-hours back to Canada.
That leaves net Canadian electricity imports equivalent to only about 0.2% of total US electricity consumption.
But that national figure disguises regional dependence.
States including New York, Michigan and Minnesota have significantly greater exposure to Canadian electricity, particularly during periods of peak demand. Interrupting those flows could therefore create regional problems even if the overall impact on US electricity consumption remained small.
That vulnerability may also be increasing.
The rapid construction of power-intensive AI data centres is placing additional pressure on electricity grids. RT notes that New York imposed a one-year moratorium in July 2026 on discretionary environmental permits for new hyperscale facilities while authorities develop regulations intended partly to protect grid stability and electricity consumers.
Electricity is therefore becoming not merely an energy commodity but an increasingly important strategic resource.
Ontario Has Used the Threat Before
This is not the first time Ford has threatened to use Ontario's electricity exports as leverage against Washington.
In March 2025, Ontario imposed a 25% surcharge on electricity exports to New York, Michigan and Minnesota before suspending the measure after Trump threatened to double tariffs on Canadian steel and aluminium.
The latest confrontation is potentially more serious because it extends across several strategically important sectors.
Canada possesses significant energy resources, critical minerals, potash and manufacturing capacity while the United States remains overwhelmingly Canada's largest export market.
That creates an unusual form of mutual dependence.
Washington has enormous economic leverage over Canada because of the size of the American market. Canada, however, controls resources and cross-border supply chains upon which particular US industries and regions depend.
Canada Prepares Dollar-for-Dollar Retaliation
Prime Minister Mark Carney has also hardened Canada's position.
According to RT, Carney accused Washington of attempting to dismantle Canada's automotive industry through negotiating demands Ottawa regarded as unacceptable.
After Canada withdrew from negotiations late Friday, Carney said the United States had “asked too much and offered too little.”
Canada subsequently announced dollar-for-dollar retaliatory tariffs scheduled to begin on September 8.
That raises the prospect of an escalating cycle.
US tariffs make Canadian goods more expensive in America. Canadian retaliation then raises costs for American exporters. Washington responds again, while provincial governments consider restricting resources or energy.
The economic consequences can ultimately fall not only on exporters but on households and businesses through higher prices, disrupted supply chains and reduced investment.
Energy and Resources Become Trade Weapons
Perhaps the most significant aspect of the confrontation is the increasing willingness to treat strategic resources as bargaining tools.
Electricity is one example.
Oil, potash and critical minerals potentially represent considerably greater leverage.
Modern economies depend on secure access to energy, minerals, semiconductors, food, fertiliser and increasingly electricity itself. The disruption of global supply chains during the pandemic, followed by sanctions and export restrictions associated with geopolitical conflicts, has demonstrated how quickly economic interdependence can become a strategic vulnerability.
The Canada-US dispute is now providing another example — this time between two countries with one of the closest economic relationships in the world.
Does This Affect New Zealand?
Potentially — and there is an important lesson for New Zealand.
The immediate economic consequences of a US-Canada trade war are unlikely to be as significant for New Zealand as they are for North America. But the dispute reinforces a broader shift in international trade.
Countries are increasingly treating energy, food, minerals, manufacturing capacity and supply chains as strategic assets rather than simply commodities traded in a global marketplace.
For New Zealand, that raises questions extending well beyond tariffs.
How dependent are we on overseas fuel supplies, medicines, fertiliser, technology and manufactured goods? Which domestic industries would become strategically important during a major international trade disruption? And where does economic efficiency end and national resilience begin?
Canada's confrontation with the United States demonstrates something particularly relevant to a small trading nation.
Economic dependence works both ways — but only if a country retains something strategically valuable enough to provide leverage.
The question for New Zealand is therefore not simply whether global trade remains open.
It is whether, in an increasingly protectionist world, New Zealand retains enough productive capacity, resources and strategic independence to protect its own national interests when other countries begin protecting theirs.
