Electricians and Electrical Contractors In Toronto
Langstaff and Sloan Inc has been providing professional electrical services in Toronto since 1991. In 1994, we were one of the four Toronto electrical contractors who participated in Toronto Hydro’s Meter Relocation program. We helped develop a similar but expanded program for Etobicoke Hydro.
This allowed our electrical contractors in Toronto to be one of the four “Authorized Contractors” of Toronto Hydro Energy Services Inc. providing residential and commercial assistance.
Residential Services remains the core of our business. Our specialty is Knob and Tube rewiring removal. Our electricians in Toronto have extensive experience with:

The Gold Standard for Licensed Electricians in Toronto and Etobicoke
In our 30+ years in the business, Langstaff & Sloan Inc. has been the “Steady Hand” for property owners throughout the Greater Toronto Area.

Deep-Dive:
The Knob and Tube Replacement Process
Many homeowners are concerned about the cost and disruption of removing Knob and Tube wiring. At Langstaff & Sloan, we have perfected a surgical approach that focuses on minimal intrusion.
Comprehensive Assessment
We map your existing system to determine exactly what needs to be replaced to satisfy modern insurance requirements.
ESA Coordination
We handle the permit application and coordinate with inspectors to ensure everything is documented for your records.
Surgical Installation
Our electricians use advanced techniques to run new copper wiring with the fewest possible holes in your lath and plaster walls.
Professional Patching
Unlike many electrical companies in Toronto, our team patches the holes we make, ensuring the finish is “patching-friendly” and ready for paint.
Final Certification
We provide the ESA Certificate of Acceptance, which is the gold standard for property insurance and resale value.
Commercial Excellence & Green Technology
As a leading commercial electrical contractor in Toronto, we embrace green technology to help our clients reduce their carbon footprint and operating costs.
LED Retrofit Lighting Solutions
Standard incandescent and halogen bulbs are inefficient for large commercial spaces. By switching to LED retrofits, Toronto businesses can save up to 70% on electricity consumption while benefiting from bulbs that last up to 25 times longer. We provide a thorough inspection and energy audit to show you exactly where your savings will come from.
High-Rise Sub-Metering
Transparency is key. Our sub-metering installations allow property managers to monitor individual unit usage, encouraging energy conservation and providing fair, accurate billing for tenants.
Why Hiring an ESA-Authorized Contractor is Non-Negotiable
Be Like Bill. Choose The Team With Proven Skills.
