How the PEI market works
Prince Edward Island kept its electricity market a regulated monopoly, and like Nova Scotia its dominant utility is privately owned. Maritime Electric, a subsidiary of Fortis Inc., distributes and bills for almost the whole province under rates approved by the Island Regulatory and Appeals Commission. The City of Summerside runs its own small municipal electric utility. There is no residential natural-gas network, so Island homes heat with electricity, oil, propane, wood and an increasingly large fleet of heat pumps.
A Fortis company serving almost all of PEI. Regulated by IRAC. No residential retail competition; the City of Summerside operates its own municipal utility.
No residential natural-gas network exists on the Island. With strong efficiencyPEI rebates, cold-climate heat pumps have become the cheapest way to heat for most homes.
Start with the national foundations

Canada is not one energy market, it is thirteen. These country-wide explainers map the two facts that decide every household bill, whether you can choose a supplier and who owns your utility, then link down into each provincial guide for the local detail.
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.
Reading the bill, the winter spike, setting up service when you move, budget billing and the levers that actually lower a bill work the same way nationwide. Learn them once here; your provincial guide supplies the local numbers.
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 national questions where accuracy matters most and the numbers move fastest: what happened to carbon pricing, which federal rebates and loans still exist, and which province really has the cheapest power. Each keeps the live figures in a dated box.
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.
