Can a smart home lower insurance costs in Canada? Published discounts and conditions
A source-based guide to home-insurance discounts for automatic water shutoff, monitored leak sensors and alarm systems, with a calculator that uses your actual premium.
The short answer
Yes, some insurers publish discounts, but the device alone does not guarantee one. Desjardins currently advertises up to 10% for a leak-detection system with automatic shutoff and up to 5% for at least five detectors connected to central monitoring. Other insurers describe eligibility without publishing a fixed percentage. Ask for a written quote before using the discount to justify the purchase.

Eligibility varies by insurer, province, building type, coverage and underwriting profile. The Insurance Bureau of Canada says insured losses from severe-weather flooding and water damage now average roughly $1 billion a year, versus $277 million annually from 1995 to 2009. That trend explains insurers’ interest in prevention, but a shutoff valve cannot prevent every type of flood and “up to” remains a ceiling, not a guaranteed discount.

Useful comparison
What insurers actually publish
These figures are not interchangeable. They describe different protection systems and use “up to” language. Your insurer’s written quote is the only number that belongs in your payback calculation.
| Published example | Maximum or condition | Important limit |
|---|---|---|
| Desjardins: leak detection plus automatic shutoff | Up to 10% on home insurance | Eligibility and actual amount must be confirmed |
| Desjardins: centrally monitored leak detectors | Up to 5%; at least five detectors | Standalone app alerts are not the same condition |
| iA: centrally monitored security system | Up to 15% published for eligible security systems | This is not a blanket water-valve discount |
| Intact: qualifying water-detection system | A discount may apply | No universal percentage published on the cited page |

FAQ
Common questions before buying
Is a Wi-Fi leak sensor enough for a discount?
Not necessarily. Some published programs require automatic shutoff or at least five detectors connected to central monitoring. Confirm the exact condition in writing.
Does a 10% discount mean 10% of the water-damage coverage?
The cited Desjardins page says up to 10% on home insurance for the qualifying automatic-shutoff system. Your policy quote must show the actual base and amount used.
Can the discount pay for the system?
Sometimes, but often slowly. Divide complete installed cost by the confirmed annual discount and include monitoring or maintenance fees.
Should I change insurers for the discount?
Compare the complete premium, coverage, exclusions, deductible and service—not one discount line. A larger discount can still produce a higher total bill.
