Energy in Canada is decided province by province, not nationally. Two questions settle almost everything on your bill: can you choose your supplier (only in Alberta, and partly in Ontario), and is your utility a Crown corporation or an investor-owned company? This map answers both for all 13 provinces and territories, with a live province selector.
The honest answer is: usually no. Alberta has full retail choice, Ontario has a limited version, and the other 11 provinces and territories are regulated monopolies with no supplier to switch to. Here is exactly what "switching" means where you live, and what to do instead when it is not an option.
Most Canadian power comes from a monopoly, but some monopolies are owned by the province and some by private shareholders. That ownership split shapes how rates are set, where your money goes, and why a rate increase is a political firestorm in one province and a quiet filing in another.
What Canadians burn to stay warm follows a clear regional map: natural gas on the Prairies and in Ontario, cheap electricity in Quebec, heating oil across much of Atlantic Canada, and oil or wood in the North. The fuel available where you live sets your winter bill far more than any rate.
Every Canadian energy bill splits into the same parts: the commodity (the energy itself), delivery (the poles, wires and pipes), fixed charges and tax. Knowing which line you can influence and which is locked by the regulator is the difference between cutting a bill and staring at it.
A winter bill can double or triple, and the reason is almost always heating, not a rate change or a billing error. Here is the physics behind the spike, how to tell a normal seasonal rise from a real problem, and the levers that flatten it.
Whether you call one utility or choose a retailer depends entirely on your province. This is the move-day checklist, the timing, the deposits and ID you may need, and the one provincial difference (Alberta and Ontario) that changes who you actually call.
An equalized or budget-billing plan spreads a year of energy cost into twelve even, interest-free payments so the winter spike does not land in one month. It does not lower what you owe, and it trues up once a year. Here is when it helps, when it bites, and how to use it well.
In most provinces you cannot shop for a cheaper supplier, so the real savings come from consumption, heating fuel, efficiency upgrades, rebates and the right billing tools. This is the province-aware order of operations that actually moves a Canadian bill.
A plain-language dictionary of the terms on a Canadian energy bill and in its market: kWh and GJ, commodity vs delivery, Crown corporation, Global Adjustment, heritage pool, Rate of Last Resort, heat pump and more, each defined in one clear sentence.
The federal consumer carbon price, the fuel charge, was removed effective 1 April 2025, so the old "the carbon tax adds X to your bill" line is now wrong. Here is how carbon pricing interacts with home energy costs in principle, what the current status actually is, and why it is still politically live.
Federal programs layer on top of provincial ones, are delivered provincially, and now centre on getting homes off fossil heating. The durable structure is here; the live amounts and deadlines (the Greener Homes Grant has closed, the Loan is fully committed, Oil to Heat Pump Affordability is open) sit in a dated box.
Quebec, Manitoba and British Columbia have the cheapest power, and the reason is durable: they are hydro-rich and publicly owned. Fossil-dependent provinces sit higher, and diesel-run northern grids highest of all. Here is the ranking logic, why it rarely changes, and the live numbers in a dated box.
A private monopoly, a municipal pocket, an independent regulator
PEI is a regulated market with no retail competition. One investor-owned utility serves almost the whole Island, with a single municipal utility inside Summerside.
One investor-owned utility, one municipal utility, one independent regulator.
Maritime Electric, an investor-owned company in the Fortis group, generates, delivers and bills electricity for almost the whole Island. The City of Summerside runs its own municipal utility inside the city. IRAC (the Island Regulatory and Appeals Commission) reviews and approves Maritime Electric's rates; Summerside's rates are set by City Council. There is no retail competition and no natural-gas network.
Investor-owned (Fortis). The utility for almost all of PEI — generator, wires and retailer in one. More than 80,000 customers.
Municipal utility inside the City of Summerside, with its own wind and solar. Rates set by City Council, not IRAC.
The Island Regulatory and Appeals Commission reviews and approves Maritime Electric's rates under the Electric Power Act.
Prince Edward Island vs the rest of Canada
PEI shares the Atlantic-Canada profile: a privately owned monopoly, no gas, oil-and-electric heating. Alberta is the opposite; Quebec is the low-cost-hydro benchmark.
Albertans pick from 60+ retailers. The wires stay regulated.
A Crown hydro utility, low rates, the Régie sets prices.
Like PEI: an investor-owned utility, no retail choice, a public regulator.
How Prince Edward Island got here
From a private island utility to submarine cables, wind farms and the heat-pump push.
Maritime Electric is incorporated and grows into the Island-wide electricity utility, later joining the Fortis group of investor-owned utilities.
Submarine cables under the Northumberland Strait connect PEI to the New Brunswick grid, ending reliance on costly on-Island generation alone.
The Island Regulatory and Appeals Commission oversees Maritime Electric's rates under the Electric Power Act, at arm's length from government.
Summerside Electric pairs its wind generation with solar and battery storage, one of the more advanced municipal energy systems in Canada.
Two new 180 MW submarine cables, owned by the Province and operated by Maritime Electric, are energized to strengthen the import link.
With no gas network, efficiencyPEI rebates drive a fast switch from heating oil to heat pumps, backed by a high and growing wind share.
The 60-second mental model
Three actors — and IRAC has the final word on Maritime Electric's rates.
Most of the Island's power is imported from New Brunswick over submarine cables, topped up by a high and growing share of on-Island wind generation.
Maritime Electric owns the wires and bills almost the whole Island; the City of Summerside runs its own utility inside the city. There is no competitive layer and no gas.
The Island Regulatory and Appeals Commission reviews each Maritime Electric rate application and approves what the utility may charge. Summerside's rates are set by City Council.
So what does this actually mean for you?
Six concrete things that change because you are a Prince Edward Island energy consumer.
You cannot pick a power retailer. Maritime Electric (or Summerside Electric) bills you, set by your address. Your savings come from usage, heating fuel and rebates, not switching.
PEI has no natural-gas network. The biggest single lever on your winter bill is your heating fuel — moving from oil to an efficient heat pump.
Maritime Electric cannot raise residential rates on its own; IRAC reviews and approves the application. The proceedings are public, so the reasoning is on the record.
The provincial efficiencyPEI programmes offer rebates for heat pumps, insulation and other upgrades that cut the kilowatt-hours and litres of oil you buy.
Most of the Island's electricity arrives from New Brunswick over submarine cables, so PEI's supply security depends on that link plus its own growing wind fleet.
