Ontario's rental water heater market is unusual: for decades, tanks were installed on monthly rental in new and existing homes, and many homeowners inherit one when they buy a house. That changes who you call, and it changes who pays.
How do I know if my water heater is rented?
Check three places. Look on the tank for a rental company's label or asset tag. Look at your bills: Enercare now bills customers directly and lists rental equipment on its bill, and older Enbridge Gas bills carried rental charges until Enbridge ended that billing in November 2024. If you bought the house recently, check the purchase agreement, which normally lists rental contracts the buyer assumes. If you are still unsure, call the companies with your address.
| Problem | Rented tank | Owned tank | Licence needed | Why |
|---|---|---|---|---|
| Water leaking from the tank or the bottom | Rental company | Plumber (usually replacement) | 306A plumber; TSSA gas tech to disconnect gas | A leaking tank body cannot be repaired |
| Leak at a pipe fitting or the relief valve | Rental company | Plumber | 306A Certificate of Qualification | Water piping and valves |
| No hot water, gas tank, pilot out | Rental company | TSSA gas technician | TSSA G2 (or G1) certificate, registered contractor | Gas appliance work |
| Gas smell near the tank | Enbridge Gas or 911, from outside | Enbridge Gas or 911, from outside | Not a repair call | Possible gas leak |
| No hot water, electric tank | Rental company | Plumber, plus an electrician if the circuit is the fault | 306A; LEC for wiring | Elements and thermostats are part of the heater; the circuit is electrical |
| Replacing an owned tank | Not applicable | Plumber, and a TSSA technician for gas models | 306A and TSSA | Water, venting and gas connections |
My rented tank is leaking. Should I call a plumber?
Call the rental company first. Enercare and Reliance both say repairs are included in the monthly rental for the life of the unit, and Reliance says that covers parts and labour. A plumber you hire yourself is at your own cost, and the company is not obliged to reimburse it. While you wait, close the cold water valve on the pipe entering the top of the tank, and for a gas tank turn the gas control to pilot or off.
Plumber or HVAC for a hot water tank I own?
It depends on the part. Water leaks, the temperature and pressure relief valve and the pipe connections are plumbing work for a 306A plumber. The burner, pilot, thermocouple, gas valve and venting of a gas water heater are gas work, which Ontario's Technical Standards and Safety Authority (TSSA) rules reserve for certified gas technicians employed by a registered fuels contractor. Many heating companies and some plumbing firms have both on staff, so ask which certificate the technician who comes will hold.
Can I get out of a water heater rental?
Usually, by buying the tank out or returning it under the terms of your agreement; read the contract for the buyout schedule and any removal fee. Two Ontario rules protect you. Since March 1, 2018, businesses may not sign you up for a water heater at your door unless you invited them first, with a 10-day cooling-off period. And since June 6, 2024, companies can no longer register a notice of security interest (NOSI) on your home's title for consumer goods such as a water heater. For a disputed contract, contact Consumer Protection Ontario or a lawyer.
What does Doyo do here?
A rented tank goes back to the rental company. For a tank you own, describe the problem to the Doyo agent with a photo of the rating label; it identifies whether the job is plumbing or gas, and plumbers on Doyo hold a 306A certificate that Doyo has checked.
