Ontario's energy industry runs on four distinct groups of organisations. Each one has a narrow job and a single point of contact. Calling the wrong one is the most common avoidable mistake in the province.
Runs the wholesale market hour by hour. Publishes the Ontario Price. Forecasts demand and manages grid reliability. Never talks to your bill.
Sets the Regulated Price Plan. Approves every distributor tariff. Licenses retailers. Handles consumer complaints once the utility has been tried first.
About 60 electricity distributors plus Enbridge Gas and two small gas utilities. Own the wires, pipes and meters. Send the bill. Handle outages and moves.
Around 6 active residential retailers plus a handful of gas marketers. Sell fixed-rate contracts as an alternative to the RPP. Do not own wires.
The pattern: the utility you actually deal with day to day is your LDC or Enbridge Gas. The regulator (OEB) only steps in for complaints the utility cannot resolve. The IESO never enters your story unless you are a wholesale market participant. Retailers are entirely optional.
The three contact mistakes that waste the most time:
Each of these calls is logged. Hours of staff time across the province get spent re-routing them every week.
"The OEB runs the grid, so they handle everything."
Almost nobody describes Ontario's split correctly on the first try. The intuition is that one big organisation called something like "Ontario Hydro" runs the entire system, sets the price, owns the wires, and handles complaints. That single organisation has not existed since 1999, when the old Ontario Hydro was broken into five separate entities. What replaced it is not one tidy box: it is a wholesale operator, a regulator, dozens of distribution monopolies, and a small competitive retail layer, each with its own scope and none of them allowed to do the other three jobs.
The result is that the same household phones the wrong organisation about the same problem year after year. People call the OEB about outages, the IESO about door-to-door sales, the LDC about regulated price changes, and the Ministry of Energy about service charges. Every one of those calls gets re-routed, and the original problem sits unattended while the customer is on hold somewhere else. Five minutes spent learning who does what saves an afternoon when something breaks.
The four actor groups, in detail
Each group has its own statute, its own funding model, and its own narrow set of things it is allowed to do. Confusing their scopes is how problems stay unsolved.
IESO
Runs the day-ahead and real-time wholesale markets after the Market Renewal Program launch. Sets the Ontario Price (which replaced the legacy Hourly Ontario Energy Price). Operates the capacity auction. Forecasts demand and manages grid reliability across the province. Does NOT bill any retail customer.
OEB
Resets the Regulated Price Plan every May 1 and November 1. Approves every distributor and gas utility tariff via rate applications. Licenses retailers and gas marketers. Writes the consumer protection rules under the Energy Consumer Protection Act. Handles consumer complaints once the utility or retailer has had a chance to fix the issue first.
LDCs
About 60 electricity distributors own the poles, wires, transformers and smart meters in their service area. Apply the OEB-set RPP rates to your hourly meter data. Handle outages, connections, moves and billing. The largest are Hydro One (rural and small towns), Toronto Hydro, Alectra Utilities (Mississauga, Brampton, Hamilton, Vaughan), Hydro Ottawa and Elexicon Energy. Enbridge Gas serves more than 98% of Ontario gas customers.
Retailers
A small number of OEB-licensed companies sell fixed-rate electricity and gas contracts as an alternative to the regulated price. Subject to a mandatory verification call, a 10-day cooling-off period and strict renewal-notice rules. Active retailers include Canadian Energy Protection, Hudson Energy, Just Energy Ontario, Onit Energy, Summitt Energy and Xoom Energy. Gas marketers cover a similar function on the gas side.
Who to call when something breaks
A simple cheat sheet. Save it to your phone, stick it to the fridge, or screenshot the table below. The column that matters is the first call: get that right and the second call usually does not need to happen.
| If your issue is | First call | Escalate to |
|---|---|---|
| Power outage or restoration | Your LDC 24-hour line | No escalation; the LDC is the only entity that can dispatch a crew |
| Gas leak or smell of gas | Enbridge Gas: 1-866-763-5427 (24/7). Leave the area first. | Local fire department if immediate danger |
| Bill question or payment plan | Your LDC (electricity) or Enbridge Gas (gas) | OEB consumer protection if unresolved after the utility tries |
| Connection, disconnection or service move | Your LDC or Enbridge Gas | OEB if the utility refuses without OEB-approved cause |
| Question about the RPP price change | OEB consumer page at oeb.ca | The RPP is set by the OEB and not negotiable |
| Door-to-door retailer pressure or cancellation | The retailer's customer service first | OEB at 1-877-632-2727 or [email protected] |
| Suspected illegal sales practice | OEB consumer protection group | Ministry of Public and Business Service Delivery for unrelated retail fraud |
| Complaint about Ontario energy policy | Ministry of Energy (provincial), NOT the OEB | Your MPP's constituency office is often more effective |
Where Ontarians waste their time
Five mis-routed calls show up repeatedly in OEB consumer reports and call centre logs across the province. Knowing the pattern saves hours.
The OEB is the regulator, not a utility. It does not own poles or send crews. Calling the OEB about an outage results in a polite redirect to your LDC and a wasted 20 minutes on hold.
The "Global Adjustment" or wholesale charge line is set by the IESO market but billed via your LDC under the OEB-approved rate. The IESO does not take retail bill calls.
OEB rules require the utility or retailer to be given a chance to resolve first. Escalating immediately to the OEB gets bounced back to step one, adding days to the timeline.
New tenants call their old distributor by reflex. The new address picks a new LDC, and the old LDC cannot start service at the new address. Always check the bill envelope of the previous tenant.
The RPP is set by the OEB through a published methodology, not by the Minister of Energy. Calling Queen's Park about a 2¢/kWh change is a dead end. The OEB consumer page explains the formula.

The OEB is a regulator, not a court
Almost every household who escalates a complaint to the OEB assumes the OEB can simply order a refund or order the utility to compensate them. That is not how it works. The OEB is an administrative tribunal: it sets the rules of the game and enforces them, but it does not award money damages to a single complainant the way a small claims court does. What the OEB can do is meaningful but indirect. It can revoke or suspend a retailer\'s licence (and has done so several times). It can attach conditions to a distributor\'s next rate order. It can require a utility to follow a specific complaint-handling process, including timelines and written responses. It can impose administrative penalties on a licensee for repeated rule-breaking.
Where this catches people out is appliance damage from an outage. The LDC publishes its own claims process on its website, and if you believe a surge or interruption damaged your equipment, that is the right starting point. If the LDC refuses the claim and you disagree, the path is not the OEB but the Ontario Small Claims Court (for amounts under $35,000) or the Superior Court of Justice for larger losses. The OEB will redirect you to the court system. Knowing that up front saves a few months.
A related quirk: the OEB does not handle complaints about policy. If you disagree with the existence of the regulated price plan, the level of the Ontario Electricity Rebate, or the way the IESO runs the capacity auction, the OEB will tell you that those are decisions of the Minister of Energy or the legislature. The OEB applies policy; it does not set it. The right address is the Ministry of Energy or, more practically, your MPP\'s constituency office.
What to actually do, in order
- Find the name on your electricity bill envelope. That is your LDC. Save its 24-hour outage line in your phone now. It will be on the front page of the bill and on the LDC homepage.
- Save Enbridge Gas emergency number. Put 1-866-763-5427 in your phone under "gas emergency". If you are in EPCOR or NRG territory, replace it with the number on your gas bill.
- Bookmark the OEB consumer page. oeb.ca has a complaints intake form. Use it only after your utility or retailer has had a written chance to fix the issue. Keep copies of every email and call note.
- Do not call the IESO unless you are a market participant. The IESO site has data, forecasts and reports. None of it requires a phone call from a residential customer.
- Triage retailer issues before escalating. Write to the retailer's customer service in plain language: account number, contract date, the outcome you want. Wait the period stated in their response. Then, if needed, forward the chain to the OEB.
- For policy frustration, write your MPP, not the OEB. Rate structure, rebate level and market design decisions are political. The OEB will redirect a policy complaint; an MPP's constituency office can actually raise it in caucus.
The split is not going to merge back
Ontario broke up the old monolithic Ontario Hydro for structural reasons that have not gone away. Wholesale market design needs a single neutral operator that does not own generation or wires (the IESO). Consumer protection needs a regulator that is institutionally separated from the utilities it oversees (the OEB). Local service needs an entity that owns and operates the physical wires at the neighbourhood level (the LDCs). Competitive supply, where it exists, needs to be optional and tightly supervised (the retailer licence regime). None of those four functions can be done well by the same organisation, and no Ontario government has seriously proposed merging them.
The Market Renewal Program changed how the IESO runs the wholesale market, the OEB has been reforming its consumer complaint process, and the LDC sector has been quietly consolidating (Alectra is itself the merger of four legacy utilities). The names move, the boundaries do not. Treating "the IESO, the OEB, my LDC and any retailer who knocks on the door" as four genuinely separate things, each with its own phone number and its own narrow scope, is the cheapest and most useful mental model you can build as an Ontario energy customer.
