If Ontario Premier Doug Ford decides to make good on his menace to chop off energy to 1.5 million properties and companies in the USA, he might want to ramp down the power produced in his province.
On Monday, Ford launched a 25 per cent surcharge on power exported from Ontario to Michigan, Minnesota and New York as a response to tariffs on Canadian merchandise introduced in by the White Home.
These surcharges — anticipated to lift as much as $400,000 per day — is probably not the top of the dispute.
“If the USA escalates, I can’t hesitate to close the electrical energy off fully,” Ford mentioned on Monday.
To chop off U.S. power, nonetheless, Ontario must minimize its personal power output. The transfer would possible imply ramping down the province’s hydro-electric output, power that can also be offered to different jurisdictions in Canada.
“We simply have to cut back the quantity of power we’re outputting proper now, and it wouldn’t be nuclear as a result of if we flip down the nuclear reactor it may take six months however hydro, we may gradual that down,” Ford defined on Monday.
In response to Ontario’s Impartial Electrical energy System Operator, it depends on its agreements with the USA to “preserve the affordability, reliability and sustainability” of its system.
The sell-on agreements with the U.S. and different provinces are particularly useful at evening and on weekends when demand is low however energy crops proceed to function, the IESO web site explains.

Promoting it to the USA, Quebec and Manitoba “permits the province to promote surplus electrical energy that may in any other case be wasted.”

To keep away from that energy being wasted — and so as to not promote it to the USA — Ontario must minimize its personal output. That would additionally imply much less power to promote to Quebec and Manitoba, Canadian provinces Ontario additionally has energy-sharing agreements with.
Ford mentioned on Monday he wouldn’t put a date on when he would possibly minimize off power to the U.S. or what would set off the motion.
The White Home has additionally promised to introduce reciprocal tariffs, with U.S. President Donald Trump saying Tuesday he has instructed his commerce secretary so as to add an extra 25 per cent tariff on Canadian metal and aluminum, starting Wednesday.
The tariff charge will now be at 50 per cent. Trump cited Ontario’s 25 per cent tax when he introduced the motion on his Reality Social platform.
Whereas Ontario sells energy to the USA, it additionally buys some in. One power professional mentioned that the surcharge may subsequently result in costlier electrical energy in Ontario.
“If there was a response, then sure, probably there may very well be a response again that may trigger electrical energy responses on imported energy,” Tom Timmins, power legislation at Gowling WLG, instructed World Information.
“Possibly we’re importing energy on chilly January mornings or scorching August afternoons, perhaps that energy could be barely costlier.”

The power minister mentioned the numbers imply the province can afford to take the chance of accelerating the value of imported power. He mentioned Ontario sells the USA 12,000 megawatt hours in comparison with the 374 it imports from south of the border.
“We’re a 31-times internet exporter, so we’re well-positioned to impose this… we’ve the flexibility,” Power and Electrification Minister Stephen Lecce mentioned.
“The IESO is absolutely assured of their capability to maintain the lights on for Ontarians and we’re going to maintain promoting and maintain producing the ability for Ontario first.”
He burdened the province was “nicely positioned” to desk the levy and even minimize off electrical provide and will depend on backups like pure fuel to ramp up and ramp down the province’s energy technology would depart it protected.
Ontario NDP Chief Marit Stiles steered the transfer may include the long-term threat of shedding American states as prospects sooner or later after the commerce battle is resolved.
“The premier takes a simplistic method to those issues and isn’t contemplating that the USA may need different locations to search for power and electrical energy,” she mentioned on Monday.
