Lachine: three and a half centuries by the river
Lachine’s first lands were granted in 1667. The canal, opened to navigation in 1825, and then the development of its water power in 1847 drew factories and made the area a major industrial centre. Lachine became a city in 1872, grew into a suburb after the canal closed in 1959, absorbed Saint-Pierre in 2000 and became a borough of Montréal in 2002. Today, close to 45,000 people live there, on 20 km².
Old Lachine
Along the river and the canal, the historic heart of the borough. You still find period installations here, fuse panels and circuits extended over successive renovations. Every time a wall is opened, it’s worth having an electrician take a look.
The Saint-Pierre neighbourhood
A former small enclave town, joined to Lachine in 2000 and now a neighbourhood of the borough. In its apartment buildings, you need to know which panel and which meter feed each unit before touching anything.
Streets built after 1959
The houses built when Lachine turned to residential development, after the canal closed. More than 60 years later, many need a bigger service entrance or panel for a heat pump, an EV charger or a finished basement.

What we find when we open the walls of an old house
In an older building, a kitchen or bathroom renovation often reveals several generations of wiring. Nothing is dangerous because it is old; it becomes dangerous when it is overloaded, damaged or poorly connected. Here is what we come across and what we do about it.
Two guides to learn more: knob-and-tube wiring in Québec (in French) and replacing a fuse panel (in French).
| What we find | What we recommend |
|---|---|
| Knob-and-tube wiring still in use | We locate it, check its condition and plan its replacement piece by piece, starting with the most heavily loaded circuits. |
| A fuse panel | We replace it with a breaker panel, sized for the house as it is today. |
| Junctions hidden behind a redone wall | We bring them back into accessible boxes, as the code requires. |
| Outlets with no ground | We add a ground or suitable protection, depending on what the circuit allows. |
| A circuit extended for an added room | We check that it isn’t overloaded and split the circuits if needed. |
Our electrical work in Lachine
Older house or 1960s house, we always start from what your installation can carry today, then from what you want to add to it.
Electrical panel
Fuses, 60 A, 100 A
Replacing a fuse panel or one that is too small, with the load calculation that justifies the capacity chosen.
Service entrance
On brick or on siding
Mast, meter base and service cable redone and firmly secured to the wall, with Hydro-Québec coordination for the power interruption.
Renovation
Kitchen, bathroom, basement
New circuits, protected outlets in damp rooms, recessed lighting: everything a renovation calls for, connected to the panel.
EV charger
House or plex
A dedicated circuit in the right spot, after checking that the service entrance can carry the charger. In a plex, we also look at which meter feeds it.
Lighting
Indoor and outdoor
Facade, yard and stair lighting, and recessed lights indoors, for homes and businesses alike.
Businesses and workshops
Commercial spaces and mixed-use buildings
Circuits for equipment, lighting for your space, a workshop subpanel: work planned so your business isn’t stopped any longer than necessary.
The Lachine Canal, one of the first sources of industrial power
In 1847, the water power of the Lachine Canal was harnessed. Industries set up along its banks to take advantage of this energy, and the corridor became one of the country’s main manufacturing centres until after the Second World War.
More than a century and a half later, Lachine’s homes no longer draw their power from the canal. They depend on their service entrance and their panel, which haven’t always kept up with the arrival of heat pumps, EV chargers and modern kitchens. That’s where we come in.

- Your panel is full. No room left for a new circuit: it’s time to plan rather than add circuits on tandem breakers.
- The main breaker trips in winter. Heating, water heater and cooking together exceed the capacity of the service entrance.
- You are renovating a room. Open walls are the best opportunity to replace old wiring.
- You are adding a 240-volt appliance. An EV charger, a heat pump or a spa calls for a load calculation before installation.
- Your insurer is asking questions. Fuses or old wiring: a written inspection helps you answer them.

You describe the project
The age of the house, what you want to add or renovate, what is causing trouble. Photos of the panel and the service entrance help a lot.
We assess on site
The master electrician checks the panel, the service entrance and the circuits involved, then gives you a written quote listing what is included.
We do the work and test it
The work is done to the Electricity chapter of the Québec Construction Code, then every circuit we touched is tested before the power is turned back on.

Electrician in Lachine: your questions
Do you work in Old Lachine and in Saint-Pierre?
Yes, throughout the borough of Lachine, from Old Lachine to the Saint-Pierre neighbourhood, for homes, plexes and businesses, as well as in LaSalle, Dorval and Saint-Laurent.
My house still has knob-and-tube wiring. Does everything need to be redone?
Not necessarily all at once. We locate the circuits still in use, check their condition and plan the replacement, starting with the most heavily loaded ones. A renovation, when the walls are open, is often the best time.
What happens to a fuse panel?
We replace it with a breaker panel, sized for the house as it is today, with the load calculation that justifies the capacity chosen. You get a written quote before we start.
Do you do the electrical work for a kitchen or bathroom renovation?
Yes: new circuits, protected outlets near water, recessed lighting and connection to the panel, in coordination with your contractor if you have one.
Do you work in Lachine businesses?
Yes, for lighting, equipment circuits and subpanels. The work is planned to keep downtime for your business to a minimum.
