Electrical Wiring Services in Toronto & the GTA
New circuits, rewiring and wiring repairs for homes and businesses across Toronto and the GTA, installed neatly and planned around how you use your space.

Reliable Wiring Behind Every Wall
Wiring is the part of your electrical system you rarely see, and ideally never have to think about. It carries power from the panel to every outlet, switch, fixture and appliance, and its condition affects everything from safety to how well your equipment performs. When wiring is damaged, undersized, outdated or improperly modified, problems can range from dead outlets to overheating connections.
Addis Electric provides electrical wiring services for residential and commercial properties throughout Toronto and the GTA. Whether you need a single new circuit, wiring for a renovation or a broader rewiring project in an older home, we plan the work carefully and leave you with a system that is organized, protected and ready for daily use.
Our Electrical Wiring Services
Wiring projects vary widely in scale. Some take a few hours; others are staged across a full renovation. What they share is the need for correct sizing, secure connections and protection suited to each circuit.
New Circuits and Dedicated Lines
Appliances such as ranges, dryers, microwaves, dishwashers and workshop tools often need, or perform best on, their own circuit. Adding dedicated circuits can relieve overloaded shared circuits and reduce nuisance trips, provided your panel has the capacity. If it doesn't, an electrical panel upgrade may come first.
Rewiring Older Homes
Some older homes still contain knob-and-tube wiring, and some homes built in the 1960s and 1970s have aluminum branch wiring. Both can raise concerns for homeowners, home inspectors and insurers. We assess what's in place and recommend partial or full rewiring where it makes sense, working to limit wall and ceiling openings wherever we can.
Renovation and Addition Wiring
Kitchens, bathrooms, basements and additions almost always need new or rerouted wiring. We work with your contractor to rough in circuits at the right stage so drywall and finishes aren't held up. Our electrical renovations page explains more about renovation projects.
Outlets, Switches and Protection
We add and relocate receptacles, install USB and weather-resistant outlets, and add GFCI or AFCI protection where required to help guard against shock and arc faults.

Wiring Solutions for Toronto's Diverse Housing
Few cities have housing as layered as Toronto's. Victorian and Edwardian homes in Parkdale, Cabbagetown and the Annex have often been renovated several times, which can leave a mix of wiring from different eras behind the plaster. Post-war homes in East York, the Kingsway and Scarborough may still have original circuits that were never intended for today's appliances. Basement conversions across the city frequently call for new circuits and careful routing through tight spaces.
In the wider GTA, homeowners in Mississauga, Brampton, Ajax, Pickering and Richmond Hill regularly call on an electrical contractor for basement finishing, garage wiring and additions. Our approach stays the same in every community: understand the existing system first, then wire the new work to fit it properly. Businesses can learn more on our commercial electrical services page.

Electrical Wiring FAQs
How do I know if my home needs rewiring?
Signs include frequent breaker trips, warm or discoloured outlets, flickering lights, a burning smell, or a home inspection report that notes knob-and-tube or aluminum wiring. An electrician can assess the wiring and recommend whether repairs or rewiring make sense.
Is knob-and-tube wiring dangerous?
Knob-and-tube wiring was not designed for modern electrical loads, has no ground conductor and may have deteriorated or been modified over time. Many homeowners choose to replace it, and some insurers ask about it. An assessment will show its condition and extent.
Can you rewire a house without opening every wall?
In many cases, yes. We plan routes through basements, attics and closets to reduce openings, although some access holes are usually needed. We'll explain what to expect before work begins.
What is a dedicated circuit and do I need one?
A dedicated circuit serves a single appliance or piece of equipment. Many high-demand appliances benefit from one, and some require one. We recommend dedicated circuits based on your equipment and panel capacity.
Do you handle wiring for basement renovations?
Yes. We wire basements for lighting, outlets, dedicated circuits and, where needed, subpanels, and we coordinate rough-in timing with your contractor.
Are permits needed for electrical wiring work?
Many wiring projects require a permit and inspection. We arrange permits and inspections where required and let you know during the quote.
