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. While our headquarters makes us the preferred Etobicoke licensed electricians, our footprint extends to North York, Scarborough, Mississauga, Markham, Vaughan, Brampton, Burlington, and Oakville.
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.

First time using this company. The owner Rob and his employees were very fast, professional and helpful. I had scheduled morning of and they had an electrician out to my location within an hour. I then needed additional work done the next day and they were able to help immediately and were very easy to work with. I will definitely continue to use them in the future. 10/10 service and very friendly. They took the time to explain things to someone who knows nothing about electrical work, something most electricians will not do.Posted on Google![]()

After finding a major issue with our electrical panel, Langstaff & Sloan diagnosed the problem for us and seamlessly guided us through an electrical upgrade and repair with minimal disruption in the dead of winter. Rob, Phil, Arsh, and the crew were professional, responsive, and have a commitment to high-quality work at a reasonable price. They'll work within your budget and won't ever be opportunistic and drive you towards the more expensive result, just the one that makes the most sense for you and your home. Very happy with the service, and can't recommend them enough for any residential work.Posted on Google![]()

L&S should be your go-to electrical contractor for both residential and commercial work. They upgraded my electrical panel, installed a Tesla EV charger, set up wired security cameras, and more — all at a great price! They have a great team and quality work !Posted on Google![]()

The crew was shockingly good, and living through a week long knob & tube upgrade with a newborn baby at home was a breeze, not the dreaded nightmare we had anticipated. The guys were very communicative and conscientious, minimally disruptive, efficient, and of course the quality of the work was top notch. Thank you to Rob, Colin, and the rest of the guys.Posted on Google![]()

The team came out and did a massive job for us. Extremely thorough and honest. Another Toronto peer quoted us $15k for the same work (which came to $4500). We will use them again.Posted on Google![]()

I can’t thank Rob enough for his incredible support in diagnosing and solving an electrical issue in my kitchen. I had been struggling with a frustrating problem—every time I used my microwave, it would trip the breaker and shut off power to my fridge as well. I was genuinely concerned, especially living in a condo where access to wiring can be tricky. Rob quickly and confidently identified the root cause of the issue: both the fridge and microwave were on the same circuit, overloading the breaker. Not only did he walk me through the technical side in a way that made perfect sense, but he also guided me step-by-step on how to test the outlets, identify the GFCI and breaker panel, and safely work around the issue until a long-term fix could be arranged. What really stood out was his patience, professionalism, and ability to explain complex electrical details in a simple, reassuring way. Thanks to Rob, I now fully understand how to avoid overloading circuits, and I feel much safer in my home. If you’re looking for someone who’s knowledgeable, reliable, and genuinely cares about solving your problem the right way — Rob is the one. Highly recommended!Posted on Google![]()

Detailed and quality service. I required electrician due to cable length too short and not sufficient to replace led podlights. The lines are inspected in detail and reorganized to gain more clearance to cable length. Work is done neatly, tidy and professionally.
