Downtown and midtown Toronto's century-old housing stock — much of it built well before modern electrical codes existed — is some of the most electrically complex in the GTA. Knob-and-tube wiring, undersized fuse panels, and decades of piecemeal additions are common in Toronto's older neighbourhoods. ESS specializes in bringing these homes up to modern code safely, alongside condo electrical work and commercial electrical service across Toronto's dense downtown core.

Learn more →Knob-and-tube wiring is common in Toronto homes built before the 1950s, and many insurers in Ontario either decline coverage or require it to be replaced before issuing or renewing a policy. We can inspect your home and tell you definitively what wiring you have and what replacing it involves.
We handle the ESA permit process as part of every job and submit it promptly once the scope is confirmed. Timelines depend on ESA's current processing times, which we can give you a realistic estimate of at the time of your quote.
