Commercial Electrician Services in Toronto Built for Real-World Business Demands

Running a commercial property in Toronto means dealing with strict electrical codes, aging infrastructure, tight project timelines, and zero room for safety risks.

Common Commercial Electrical Issues We Solve

Commercial electrical systems face different pressures than residential setups. Higher loads, shared infrastructure, tenant turnover, and evolving code requirements create ongoing challenges.
 
Businesses call us when they experience:
  • Lighting that no longer meets safety or productivity needs
  • Breakers tripping during peak usage
  • Electrical panels exceeding original capacity
  • Tenant improvements requiring fast Electrical Safety Authority (ESA) coordination
  • Aging wiring uncovered during renovations
  • Equipment failures disrupting operations
 
As experienced commercial electricians in Toronto, we address issues at the source rather than relying on short-term fixes that lead to repeat failures.

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.

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.

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 !

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.

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.

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!

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.

Frequently Asked Questions

How do you minimize disruption during commercial electrical work?

You don’t shut down an entire business to fix its electrical systems. Work is planned around operating hours, tenant needs, and critical equipment. Phased scheduling, temporary power solutions, and clear coordination keep operations moving while upgrades or repairs are completed safely.

What happens if an inspection fails or issues are flagged by ESA?

Problems get resolved quickly and correctly. Our team reviews deficiencies, completes corrective work, and coordinates follow-up inspections so projects move forward without extended delays or guesswork.

Can you take over projects started by another contractor?

Yes. We’re often called in when projects stall, inspections fail, or documentation is incomplete. The first step is a site assessment to identify risks, code gaps, and next steps before moving forward responsibly.

Do you support multi-tenant and mixed-use buildings?

Yes. Our commercial electricians regularly work in environments where multiple tenants share infrastructure. Submetering, coordinated shutdowns, and staged upgrades help prevent disputes and downtime.

Are your commercial electricians licensed and insured in Ontario?

All work is completed by licensed, insured electricians in compliance with Ontario electrical codes and ESA requirements. Documentation is provided so property owners and managers have clear records for audits and future planning.
