Quick answer
Yes. Since March 1, 2018, Ontario's Consumer Protection Act bans unsolicited door-to-door sale or lease of furnaces, air conditioners, water heaters, air cleaners, water treatment devices and duct cleaning, and a contract signed in breach is void: you can keep the equipment without obligation. If you invited the company, you still have a 10-day cooling-off period, and longer where required disclosure was missing.
You can cancel a door-to-door HVAC contract in Ontario, and in many cases the contract was never valid to begin with. The rule turns on one question: did you contact the company and invite them, or did they show up? The answer decides whether the agreement is void outright or cancellable within a set window. Confirm the current periods with Consumer Protection Ontario before you send anything, because the regulations are amended from time to time.
What the March 2018 door-to-door ban covers
From March 1, 2018, a business cannot come to your home uninvited and sell, rent or lease any of the following:
- Furnaces.
- Air conditioners.
- Water heaters.
- Air cleaners and air purifiers.
- Water treatment devices: purifiers, filters and softeners.
- Duct cleaning services.
- Any product that combines one or more of those functions.
A contract for one of these, signed at your door in breach of the ban, is void. Ontario's published guidance is direct: you can keep the goods or services without obligation, and the business has to reimburse what a third party charges you to remove the equipment.
When the ban does not apply: invited visits and existing customers
Two situations fall outside the ban. If you called or emailed the company and asked them to come to your home to sell you that product, the visit is legal. A business you already hold a written contract with may also offer you a restricted product during a visit, but only if it told you beforehand that it intended to. A technician who arrives for a rental-tank service call and produces a furnace lease with no warning has not met that test.
A legal in-home contract still comes with a 10-day cooling-off period, counted from the day you receive your written copy. Inside those ten days you can cancel for any reason. The window stretches to one year where the contract left out required information or the salesperson made a false or misleading statement about it.
How to cancel a door-to-door contract, step by step
- Find the paper. You need the contract, the company's legal name and address as printed on it, the date you signed and the date you received your copy.
- Write a short cancellation notice: your name and address, the contract date and number, and one sentence saying you are cancelling under the Consumer Protection Act, 2002. Inside the cooling-off period you do not have to give a reason.
- Send it by registered mail or by email, the two methods Ontario's guidance names, and keep the receipt or the sent message. Proof of delivery is the whole point.
- Photograph the equipment, its rating plate and the installation as it sits, including the vent and gas connections.
- Keep a record of every charge, and ask your bank about stopping pre-authorized payments once the notice is sent. For most contracts the company has 15 days to return your money.
- If the company refuses or goes quiet, file a complaint with Consumer Protection Ontario at 416-326-8800 or 1-800-889-9768.
What to do about the equipment already in your basement
Do not disconnect a gas appliance yourself, and do not leave it unchecked either. The faults that turn up on rushed installs are predictable: a plastic vent pipe sloped the wrong way, a water heater left alone on a chimney it can no longer draft into, a flexible gas connector run through the cabinet wall. Have a TSSA-licensed technician look at the installation, write down what is there, and confirm it is safe to run while the dispute plays out.
Check two more things. If the salesperson's crew removed a tank that was itself a rental from another company, call that company, because an unreturned tank stays on your account. And find out whether a notice was registered against your house; what a NOSI is explains why those registrations are now deemed expired.
If the cancellation window has passed
Do not assume time has run out. A contract signed at the door after March 1, 2018 in breach of the ban may still be treated as void, so put the question to Consumer Protection Ontario with your dates in hand. Where the contract is valid, the usual exit is a buyout, and getting out of a furnace rental contract covers that route. For a water heater, weigh the payout figure against the published cost of owning:
- Renting a tank: $25–$45 per month, rising with annual increases.
- Buying a gas tank outright: $1,500–$3,000 installed.
- Straight tank-for-tank replacement once a rental is returned: $1,200–$2,500 installed.
