How to Cancel Your Water Heater Rental Contract in Ontario

Millions of Ontario homeowners rent their water heater without realizing they're paying far more than they need to. Here's how to get out — and what it actually costs.

If your water heater is supplied by Reliance Home Comfort, HomeServe, Enercare, or another rental company, you're likely paying $30–$60 per month — $360–$720 per year — for a tank that the company owns. Over 10 years, that's $3,600–$7,200 for a piece of equipment worth $1,000–$1,500 to buy outright.

The good news: you can cancel. The process takes one phone call and some paperwork. Here's exactly how to do it in Ontario.

Step 1: Find Your Contract

Before you call, locate your rental agreement. It should show:

If you can't find your contract, check your gas bill — rental charges often appear there. You can also call your provider and ask for your contract details.

Step 2: Understand Your Options

When cancelling, you'll typically have three choices:

Typical buyout costs: A unit less than 5 years old may cost $800–$1,500 to buy out. Older units (7–10+ years) are often much less, sometimes under $300. Always ask for the buyout amount before deciding.

Step 3: Call and Cancel

Call your rental company directly. Here's what to say and do:

  1. Tell them you want to cancel your rental agreement
  2. Ask for the full buyout price and the return/removal process
  3. Get a cancellation confirmation number
  4. Ask them to send written confirmation by email
  5. Schedule their removal visit if returning the unit
Watch for: Rental companies often try to retain customers by offering reduced rates, new equipment, or "loyalty" deals. These can be legitimate — but run the math first. A reduced rate of $20/month is still $2,400 over 10 years for a tank you don't own.

Step 4: Get Your Replacement Water Heater

Once the rental unit is removed (or you've bought it out), you'll need a replacement. Your options:

Don't let the rental company pressure you into a new rental "deal." You're better off owning.

What About the Ontario Energy Board Rules?

The Ontario Energy Board (OEB) regulates door-to-door energy contract sales and has rules specifically about water heater rentals. Contracts signed at the door have a 10-day cooling-off period where you can cancel with no penalty. If you were signed up without proper disclosure, you may have additional cancellation rights — contact the OEB at 1-877-632-2727.

Real Numbers: Rent vs. Own

Let's say you're paying $40/month to rent a conventional gas tank water heater. Over 10 years:

And at the end of 10 years, you own the asset. With a rental, you own nothing.
