    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.

    Toronto’s unique architectural history presents distinct infrastructure challenges. We specialize in the “hidden” risks associated with older homes, specifically aluminum wiring branch circuits and heritage knob and tube rewiring.

    If you are looking for residential electricians in Toronto who understand the nuances of GTA building codes, our team provides the surgical precision required to modernize your system without unnecessary destruction.

    For commercial partners, we are the electrical contractor Toronto managers turn to for leasehold improvements and emergency troubleshooting. We coordinate directly with utilities and the Electrical Safety Authority (ESA) to handle the permitting “headaches” on your behalf. Whether you require a residential electrician in North York for a renovation or Scarborough electrical contractors for complex industrial wiring, we deliver safety-first power on schedule and on budget.

    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

    In Ontario, hiring a licensed electrical contractor isn’t just a suggestion—it’s a legal and safety requirement. Langstaff & Sloan is an ESA Authorized Contractor, meaning we are vetted for compliance and safety. We handle all necessary permits and inspections, providing you with a Certificate of Acceptance—the only proof that your electrical work meets the Ontario Electrical Safety Code.

    Don’t risk your home or business with uncertified labor; work with the best electrician Toronto has to offer.
