Why Montreal buildings carry water risk
Montreal is a city of plexes and walk-ups. Seven in ten occupied homes are flats in duplexes or in apartment buildings under five storeys, two thirds were built before 1981 and most households rent. The City is still replacing lead water service lines in buildings of eight units or fewer built before 1970, a reminder of how old the plumbing in that stock can be. In a stacked plex, a failed fitting upstairs runs straight into the flat below.
The newer city is rising fast. Montreal's housing starts jumped in 2025, led by rentals, while condo starts fell to a record low. Griffintown alone added thousands of homes between 2007 and 2023 on former industrial land. New towers carry their own early failures at fittings, appliance hoses and HVAC connections. Condo syndicates now carry more of every water loss themselves, through high water deductibles and the self-insurance fund Quebec law requires.
Winter raises the stakes. Montreal's airport station averages about 148 days a year with a low at or below freezing and about 14 nights colder than minus 20. In January 2026, burst pipes flooded about half of an aging Montreal hospital research building and damaged four labs. Officials pointed to the cold. Eddy's 24/7 monitoring center confirms every alert, calls the building's contacts through the escalation protocol within minutes of the SMS, email and app alerts and can close a valve remotely when the response plan calls for it.
Where leaks start in Montreal buildings
Plexes and walk-ups with aging plumbing
Seven in ten Montreal homes are flats in duplexes or low-rise walk-ups, and two thirds were built before 1981. In a stacked plex a failed fitting upstairs soaks the flat below, and the first sign is often a stain on the ceiling.
Frozen and burst pipes
Montreal's airport station averages about 148 days a year with a low at or below freezing. Supply lines in exterior walls, parking garages and vacant units are the first to freeze. The break often shows only when the pipe thaws.
Dense new rental and condo towers
Rentals made up most of Montreal's 2025 housing starts, and Griffintown alone added thousands of homes between 2007 and 2023. New towers see early failures at fittings, appliance hoses and HVAC lines. One riser leak can reach many suites at once.
Water deductibles the syndicate must fund
Insurers generally give syndicates a separate water damage deductible, which reports in 2021 and 2022 put at $25,000 or even more than $100,000. In some downtown towers it can reach half a million dollars. Bill 141 makes the syndicate build a self-insurance fund toward its highest deductible, so every prevented claim protects that fund.
Smart leak detection in Montreal
A smart water leak detection system pairs wireless sensors and smart meters with automatic shutoff, so a Montreal building catches a leak in seconds instead of discovering it from a ceiling stain. Eddy runs the full stack as one managed program with a staffed 24/7 monitoring center on the chain.
Sensors plus flow intelligence
3-in-1 wireless sensors watch high-risk spaces for water, temperature and humidity while smart meters flag abnormal flow against thresholds learned from the building's own baseline.
No building Wi-Fi needed
Devices run on Eddy's own LoRaWAN network at 915 MHz, a long-range radio that holds a signal through concrete. Gateways backhaul over Ethernet or LTE cellular, and with cellular backhaul monitoring stays up even if building internet goes down.
Shutoff plus a live response
Automatic valves close the moment a configured rule fires, and Eddy's monitoring center calls the building's contacts within minutes of every alert. Every confirmed event closes with a Leak Incident Report.

Coverage map
How Eddy works in a Montreal building.
Montreal's long, deep winters put supply lines in exterior walls at risk, and in tightly packed buildings one leak can reach many units at once. Turn the building to see where sensors, meters and valves sit, then run a leak through the system, from the first drop to the monitoring center's response.

What happens in a leak, step by step
- A washing machine supply hose bursts in a suite upstairs.
- Eddy H2O under the washer detects water and sends the alert over LoRaWAN.
- The building's gateway relays it. Your team and the 24/7 monitoring center are alerted at the same time.
- A shutoff rule closes the suite's Eddy IQ valve. The water stops at the source.
- An operator confirms the alert and calls your on-site team through the escalation protocol.
Automatic shutoff is configured per building. Some sites use operator-coordinated isolation instead.
Smart sensors at every leak point
Eddy places point-of-leak sensors and smart flow meters where water damage actually starts in Montreal buildings, from the mechanical room to a laundry hose, so a leak is caught at the source and shut off before it spreads.

Mechanical rooms
Boilers, water heaters and main risers, where a single failure floods fast.

HVAC and fan coils
Heat exchangers and condensate lines that drip behind walls and ceilings.

Kitchens
Supply lines, shutoffs and appliance connections under and behind the sink.

Bathrooms
Toilets, vanities and concealed in-wall fixtures on every floor.

Laundry
Washer hoses and laundry connections, a top source of overnight leaks.
Every minute changes the bill.
A leak gets bigger the longer it runs. Eddy detects in seconds and the monitoring center escalates within minutes, so the same failure is contained around minute two. Unmonitored, an after-hours leak runs six to eight hours before anyone arrives.
The leak starts at minute zero. Eddy contains it around minute two. Unmonitored, the same leak runs six to eight hours before staff arrive, and that red stretch is the avoided claim.

Bill 141 and Bill 16 for syndicates
Quebec has rebuilt its condo rules around insurance and maintenance. Under Bill 141, every syndicate must build a self-insurance fund up to its highest deductible, not counting earthquake or flood, although contributions can be reduced once the fund holds at least $100,000. The Bill 16 regulation, in force since August 14, 2025, adds a maintenance logbook and a contingency fund study every five years by a qualified professional, and existing syndicates have three years to comply. Documented water monitoring replaces neither. It gives the board and its professionals an event-by-event record of how the building's water systems behave.
A team behind every alert
A 3 a.m. alert is one chime. Nobody is awake to hear it.
Fast response is not just the hardware. The technology sees the water in seconds, and the managed service behind it, a monitoring center that calls your team within minutes, turns that into a contained event before it becomes a claim.
Tuned by real events
Built over a decade in operating buildings.
Eddy has been inside buildings since 2014. Sensor placement, alert thresholds and the monitoring-center playbook are tuned by what real water events across our monitored properties keep teaching us.
Built for the building
Sized to how the water system behaves.
Multi-family stacks, commercial towers, hospitality suites, course-of-construction projects. Each water system has its own failure pattern. The coverage map, response chain and shutoff sequence are scoped to the property in front of us, not a template.
Detect, contain, document
Every event leads to a closed incident.
Sensors find where water escaped. Automatic shutoff isolates the affected zone. The 24/7 monitoring center calls your team within minutes and stays on it until it's closed, with a Leak Incident Report on file.
Built for dense winter-climate stock
Eddy protects the kind of dense, freeze-exposed residential and commercial buildings Montreal is full of, with escalation and shutoff handled around the clock by the monitoring center.
Eddy at work in Montreal and across Canada
Multi-family
A badly installed fixture could have leaked for months. It was isolated the same day.
Montreal, Quebec
A resident-added fixture was not seated properly and began a slow leak under a bathroom sink, with no one to report it. Eddy detected the water near the sink, the source was identified as an installation defect, and the leak was isolated the same day with no spread.

- Facility operator
Multi-family
A fan coil failed in an empty suite. The line was isolated before anyone set foot inside.
Ottawa, Ontario
A failing fan coil pulled abnormal make-up water through the heating and cooling loop in an unoccupied suite. Eddy detected the abnormal flow, the affected line was isolated remotely before prolonged loss, and a plumber completed the repair.

Multi-family
Two washing-machine events in one week. Both shut off automatically.
Toronto, Ontario
In a purpose-built rental tower protected from day one, two separate washing-machine events were intercepted in a single week. Each time the suite's water valves shut off automatically the moment the sensor triggered, containing both events to single suites.

Montreal water leak detection FAQ
Do you serve Greater Montreal?
Yes. Eddy protects condo, commercial and multifamily buildings across the island of Montreal, from downtown to the West Island. The wider region is served the same way, including Laval, Longueuil, Brossard and the North and South Shores.
How does Eddy handle a freeze-night burst?
Operators in the monitoring center confirm the alert and call the building's contacts through the escalation protocol within minutes of the SMS, email and app alerts. Water can shut off automatically or on a remote command, any hour of the night.
Can you protect an older walk-up or plex condo?
Yes. Eddy layers onto existing buildings without a full plumbing overhaul. Wireless sensors and flow monitoring install around the systems you already have, with no drywall cuts, which suits a plex where every flat sits over another.
Does monitoring protect our syndicate's self-insurance fund?
Every water claim draws on the fund your syndicate must build toward its highest deductible, so prevention protects it. Eddy's technology is approved by most insurers across North America to provide deductible or premium savings. Programs have documented premium savings of up to 20%, and deductible reductions of up to 80% have been documented at individual properties.
Will a leak show up on our water bill in Montreal?
It can. Since January 1, 2023, Montreal has billed buildings that are wholly or partly non-residential, mixed-use buildings included, for the water their meters record, with higher rates in the higher consumption blocks. Flow monitoring flags abnormal flow on the lines it watches, so a hidden leak does not run for months on the meter.
How Eddy works
What is Eddy Solutions?
Eddy Solutions is managed water leak detection for builders, commercial asset managers and property managers, hospitals, hotels and conference centers, data centers and multifamily residential buildings across Greater Montreal. It combines point-of-leak and flow sensors, automatic shutoff, building wireless connectivity, a 24/7 monitoring center and insurance-grade reporting into one program from one vendor, so a leak is detected, contained, escalated and documented without your team running the response.
Eddy monitors 150,000+ active devices across North America and has prevented an estimated $98M (USD) in property damage last year alone. Aon's independent study found Eddy would have positively affected 58% of water-loss claims in commercial real estate.
How do we choose a commercial water leak detection company in Greater Montreal?
Look for five things. Sensors where leaks start, not only a meter on the main. Shutoff valves that close on their own when water runs. A staffed monitoring center that calls your team instead of only sending an app alert. Wireless coverage that holds a signal through concrete to mechanical rooms and parking levels. And a documented record of every event that your insurer can read.
Eddy covers all five for buildings across Greater Montreal, from a single tower to a full portfolio, with 150,000+ active devices in the field.
What happens after hours?
The 24/7 monitoring center is the after-hours response. Trained operators confirm every alert, escalate per the building's contact list, support the on-call contact, and stay on the line until the water is off and the response is verified.
Will this affect our insurance?
Yes. Eddy Solutions' technology is approved by most insurers across North America to provide deductible or premium savings. Given differences in asset types and building risk profiles, insurance incentives are not uniform. For specific insurance questions related to your property in Greater Montreal, please reach out directly to sghanbarian@eddysolutions.com.
How is the system sized for a building, and what does it cost?
Eddy's team walks the building, or reviews the construction drawings, and produces a tiered design matched to the asset class, water systems and insurance program. Our first step is an exploratory call with the relevant stakeholders to understand the problem you are looking to solve. Proposals come from our technical team in 7 days or less.
You can also get started immediately with our Build Your System tool at eddysolutions.com/build-your-system.
Do we have to open walls to install Eddy?
No. Sensor installs need no drywall cuts. Wireless sensors sit where leaks start, at fixtures, appliances, fan coils and the foot of each riser, and Eddy provisions and configures the meters and valves on the lines that need them.
What is smart water leak detection?
Smart water leak detection uses connected sensors and flow meters to watch a building's plumbing in real time, instead of waiting for someone to find a leak. Point-of-leak sensors catch water at the source and smart flow meters spot an abnormal run or a burst riser, and the system can shut the water off automatically or on a remote command. With Eddy, a 24/7 monitoring center acts on every alert, so detection turns into a response, not just a notification.
How is commercial water leak detection different from a home leak detector?
A home leak detector is usually a single sensor that pings an app. Commercial and multifamily leak detection has to cover dozens of risers, suites and mechanical rooms, hold a signal through concrete and steel and produce the documented response insurers expect. Eddy is built for that scale, with building-grade LoRaWAN wireless, point-of-leak and flow coverage across the property, automatic shutoff up to building mains and a managed 24/7 monitoring center.
What is the difference between leak detection and water leak protection?
Leak detection finds the water. Water leak protection stops the loss. Detection on its own is an alert that still needs someone to act on it. Eddy pairs detection with automatic shutoff and a 24/7 monitoring center that escalates the alert and closes the water, so the building is protected, not just alerted.
Does Eddy work for both multifamily and commercial buildings?
Yes. Eddy protects multifamily and condo towers, Class A offices and mixed-use buildings, hospitality, institutional and industrial properties and active construction sites. The same managed program tunes the sensor density, shutoff strategy and reporting to how each building's water system behaves. See the full product suite at eddysolutions.com/products.
