Toronto, Canada| Ontario Premier Doug Ford has announced a 25% surcharge on all electricity exports to the United States in response to President Donald Trump’s latest round of tariffs.
The move, which Ford framed as a countermeasure to what he described as “damaging” U.S. trade policies, signals a sharp escalation in tensions between Canada’s most populous province and its largest trading partner.
“This is about standing up for Ontario,” Ford stated in a press release on Monday. “President Trump’s tariffs are a disaster for the U.S. economy. They’re making life more expensive for American families and businesses. Until the threat of tariffs is gone for good, Ontario won’t back down. We’ll stand strong, use every tool in our toolkit, and do whatever it takes to protect Ontario.”
The Ontario government has swiftly implemented the measure by issuing an enabling regulation under the Electricity Act, amending the market rules overseen by the province’s Independent Electricity System Operator (IESO).
Energy Minister Stephen Lecce has directed the IESO to require electricity generators to apply a “tariff response charge” to all power exports to Michigan, Minnesota, and New York.
Financial and Economic Impact
The surcharge translates to approximately $10 per megawatt-hour, generating an estimated $300,000 to $400,000 in daily revenue.
The Ford government has stated that these funds will initially be used to offset the economic burden of U.S. tariffs on Ontario workers and businesses.
However, officials have not ruled out increasing the surcharge or even halting electricity exports altogether.
Ontario currently exports $700 million worth of electricity annually to the U.S.—enough to power 1.5 million homes.
Any significant disruption in this supply could have broader implications for electricity markets in both countries.
The decision to implement the surcharge through regulatory amendments bypasses the need for legislative approval, allowing the government to act swiftly.
Originally, Energy Minister Lecce indicated that such a measure would require legislation, but Ford expedited the process.
Ontario’s legislature is not scheduled to reconvene until April following last month’s provincial election.
Potential Consequences for the U.S. Power Grid
Energy analysts have warned that Ontario’s retaliatory measures—along with similar actions being considered in other provinces—could have far-reaching consequences for North America’s heavily integrated power grid.
Many U.S. states, particularly those in the Northeast and Midwest, rely on imported Canadian electricity to stabilize prices and prevent power shortages during peak demand periods.
“If Ontario follows through with the surcharge or even suspends electricity exports entirely, it could lead to higher energy costs and a greater risk of brownouts in some U.S. states,” said Mark Stevens, an energy policy analyst based in Toronto.
“The North American power market operates as an interconnected system, so disruptions in one region can ripple across borders.”
Other Canadian Provinces Weigh Similar Actions
Ontario’s move is not isolated. Other Canadian provinces that supply electricity to the U.S. are also considering retaliatory measures:
- Manitoba: The Manitoba government has directed Manitoba Hydro to seek cabinet approval before signing new electricity export agreements with U.S. customers or renewing existing contracts. This added layer of oversight could slow down negotiations and limit future cross-border electricity trade.
- Quebec: The Quebec government has stated it is evaluating potential restrictions on certain types of power exports to U.S. customers, though it has not yet announced specific measures. Quebec is the largest electricity exporter in Canada, primarily supplying New York and New England through Hydro-Québec.
Escalating Trade Tensions
Ford’s decision adds to the growing economic friction between Canada and the U.S., as Trump’s tariffs continue to impact industries on both sides of the border.
The U.S. president has defended his tariffs as necessary for protecting American manufacturing and energy independence, while Canadian officials argue they unfairly target key sectors, including steel, aluminum, and now electricity.
Diplomatic efforts to ease trade tensions have so far been unsuccessful, and the introduction of electricity-related countermeasures could further complicate negotiations.
Industry groups on both sides of the border have urged caution, warning that prolonged economic retaliation could disrupt supply chains and raise costs for businesses and consumers alike.
What Comes Next?
Ontario’s government has signaled that it will continue monitoring U.S. trade policies and is prepared to take further action if necessary.
The Ford administration has not ruled out increasing the electricity surcharge or completely cutting off exports if Trump’s tariffs remain in place.
Meanwhile, U.S. energy regulators and state governments are assessing the potential impact of Ontario’s surcharge.
Some officials in affected states have expressed concern over rising energy costs, while others have called for negotiations to resolve the dispute before it escalates further.
With Canada-U.S. trade relations already under strain, Ontario’s latest move highlights how economic conflicts are increasingly spilling over into critical infrastructure sectors.
As both sides dig in, businesses and consumers in both countries may soon feel the effects of this escalating power struggle—quite literally.
