Contract Traps, Failures and Official Sources
How to complain about an HVAC contractor in Canada: steps and bodies by province
A step-by-step route for disputes with furnace, heat pump and water heater contractors in Canada, from written demand to consumer offices, safety authorities, RBQ security and small claims.
If an HVAC contractor will not fix a faulty installation, refund a deposit or honour a warranty, the usual route in Canada is: put the problem in writing with a deadline, then complain to your provincial consumer protection office, and, if the amount justifies it, sue in small claims court (or use the Civil Resolution Tribunal in British Columbia) within the limitation period. Separate routes exist for unsafe gas or electrical work (the provincial safety authority), for Quebec contractors (the RBQ licence security can compensate some losses), for door-to-door and rental contracts (special cancellation rules), and for fraud (police and the Canadian Anti-Fraud Centre). Most disputes are settled at the first or second step if your documents are in order.
This guide is part of HVAC problems and official sources. It is general information, not legal advice; for larger claims, speak to a lawyer or, in Quebec, a lawyer or notary.
Step 1: build your file
- Contract, quotes, invoices and proof of payment (credit card statements, cheques, e-transfers).
- Model and serial numbers, warranty registration, permits and inspection results.
- Photos and videos of the problem, dated; thermostat history; utility bills before and after.
- A timeline of calls, visits and messages, with names.
- Any written diagnosis from another licensed contractor.
Step 2: written demand
Send a short letter or email: what was agreed, what went wrong, what you want (repair, refund, a specific amount), and a reasonable deadline, such as 10 or 15 days. Refer to the contract clause or warranty. Keep proof of sending. Many provincial consumer offices publish template letters.
Step 3: the right body for the problem
| Problem | Where to go |
|---|---|
| Unsafe gas work, CO risk, suspected unlicensed gas fitter | Ontario: TSSA; BC: Technical Safety BC; Quebec: RBQ; other provinces: the gas safety authority. In an emergency, leave the home and call the gas utility's emergency line or 911 |
| Unsafe or unpermitted electrical work | Ontario: Electrical Safety Authority; BC: Technical Safety BC; elsewhere: provincial electrical safety office |
| Contract, deposit, misleading sales, door-to-door | Ontario: Consumer Protection Ontario; Quebec: Office de la protection du consommateur; BC: Consumer Protection BC; Alberta: the provincial consumer protection office; other provinces: consumer affairs office |
| Quebec contractor did not finish, took a deposit or did poor work | RBQ licence security, plus the OPC and the courts |
| Program rebate refused because of contractor paperwork | The program administrator, then the contractor |
| Fraud or identity theft | Local police and the Canadian Anti-Fraud Centre |
| Misleading advertising | Competition Bureau Canada |
| Financing dispute | The lender's complaint process, then the external complaints body named in the agreement |
Consumer offices can mediate, investigate patterns and, in some cases, prosecute; they generally do not award you damages.
Quebec: RBQ licence security
Contractors licensed by the Régie du bâtiment du Québec must provide licence security, which can compensate consumers for losses such as deposits, non-completion or poor workmanship within set limits and time frames. The security is a fixed total amount that may be shared among all eligible claimants against the same contractor, so file early. Check the RBQ's current conditions.
Step 4: small claims and tribunals
| Province | Forum | Notes |
|---|---|---|
| Ontario | Small Claims Court | Check the current monetary limit on the Ontario courts site |
| Quebec | Court of Québec, Small Claims Division | Lawyers generally cannot represent parties; limit is set by law |
| British Columbia | Civil Resolution Tribunal for claims up to $5,000; Provincial Court above that within its limit | CRT is online |
| Alberta | Court of Justice civil claims | Check the current limit |
| Other provinces | Provincial small claims courts | Limits vary |
Limitation periods. In Ontario, BC and Alberta, the basic limitation period is generally two years from when you discovered the claim; in Quebec it is generally three years. Some contract or warranty deadlines are shorter. Do not wait for a contractor's promises to run out the clock.
Worked example: valuing a claim
Illustrative: a contractor installed an undersized heat pump without the agreed backup strips and stopped responding.
- Cost to add the backup strips and fix the wiring, from a second contractor's written quote: $1,850 + HST 13% = $2,090.50.
- Extra electricity for space heaters used for six weeks: 900 kWh × $0.15 = $135.
- Total claim: $2,090.50 + $135 = $2,225.50, plus court filing costs if you sue.
Claims are easier to prove with written quotes for the repair and documented costs than with estimates of inconvenience. Paying by credit card can also allow a chargeback request for services not provided; ask your card issuer quickly, as time limits apply.
Special situations
- Door-to-door contracts in Ontario for furnaces, water heaters and similar products are void if the seller came uninvited; see the door-to-door ban.
- Rental disputes often turn on buy-out and removal clauses; see rental contracts.
- A lien or NOSI on title: see notices of security interest.
- Warranty refusals: see warranty registration and installation failures.
Online reviews are not a legal remedy and can expose you to a defamation claim if they go beyond the facts. Stick to what happened and what you can document.
FAQ
Can the consumer office get my money back?
Usually it can mediate and take enforcement action against businesses that break the law, but it is not a court. For compensation, you may need small claims.
What if the contractor has gone out of business?
In Quebec, check the RBQ licence security. Elsewhere, a claim against a closed company may be hard to collect; manufacturers may still honour parts warranties through another contractor.
Should I stop paying?
Withholding payment can be appropriate for unfinished work if the contract allows it, but it can lead to a lien or collection. Get advice before withholding a large amount.
