Basement Electrical Wiring in Toronto
Electrical rough-in and finishing for basement renovations and legal second suites.
Call (416) 828-6976Serving Toronto
From downtown condos to century homes in the older east and west end neighbourhoods, Toronto properties bring a wide range of electrical challenges: aging knob-and-tube wiring, undersized panels, and condo board requirements for EV charger installations. Our licensed electricians work across the city, providing code-compliant electrical service for homeowners, landlords, and businesses alike.
In older pockets like The Annex, Riverdale, and High Park, the most common calls we get are knob-and-tube and aluminum wiring assessments, panel upgrades ahead of a renovation, and insurance-driven electrical inspections during a home sale or refinance. In denser areas like Yorkville and downtown condo corridors, the work skews toward in-suite troubleshooting, lighting upgrades, and condo board–approved EV charger installations in shared parking garages. In The Beaches and Leslieville, potlight and backyard lighting installs are common alongside general panel and outlet work in century homes.
We regularly work in:The Annex,Leslieville,The Beaches,High Park,Riverdale,Yorkville, and the rest of Toronto.
More about our work in Toronto
Overview
We provide basement electrical wiring for homes and businesses throughout Toronto, including The Annex, Leslieville, The Beaches, High Park, and the rest of Toronto.
Finishing a basement, or converting it into a legal second suite, means the electrical work has to be planned properly from the start: new lighting and outlet circuits, dedicated circuits for larger appliances, GFCI protection where required, and enough panel capacity to support it all. We handle the full scope, from rough-in wiring through trim-out, and we know the additional requirements that apply specifically to legal basement apartments, like interconnected smoke and CO alarms and proper circuit separation.
- Full rough-in through trim-out
- Legal second suite wiring requirements
- Panel capacity assessed before work starts
Why It Matters
A basement renovation is one of the few jobs where the electrical scope is easy to underestimate, because a finished basement usually needs more circuits than the unfinished space ever had: dedicated lighting, general-use outlets spaced to code, GFCI protection near any wet areas, and often a dedicated circuit for a bathroom, kitchenette, or laundry hookup. If you’re creating a legal second suite, the requirements go further, with interconnected smoke and CO alarms shared between units, and clear circuit separation, which is now a bigger topic across Ontario as municipalities make it easier to add basement apartments. Planning the electrical scope before drywall goes up saves you from expensive rework later.
How Basement Electrical Wiring Works
- 1
Layout & load planning
We review your basement layout and confirm your panel has capacity for the new circuits, recommending an upgrade first if it doesn’t.
- 2
Rough-in wiring
We run wiring for lighting, outlets, and any dedicated appliance circuits before drywall goes up.
- 3
Second suite requirements
For legal basement apartments, we wire interconnected smoke and CO alarms and keep circuits properly separated between units.
- 4
Trim-out & inspection
We install switches, outlets, and fixtures, then schedule the ESA inspection for your permit documentation.
What Affects the Cost
Cost depends on the size of the basement and number of circuits needed, whether the space is being finished for general living or as a legal second suite, and whether your panel has spare capacity or needs an upgrade first.
Frequently Asked Questions
- Do I need a permit for basement electrical wiring?
- Yes, any new wiring, including basement rough-ins, requires an ESA permit and inspection, which we pull and schedule as part of the job.
- What’s different about wiring a legal basement apartment?
- Legal second suites require interconnected smoke and CO alarms shared between the upper and lower units, proper circuit separation, and often a dedicated electrical panel or sub-panel for the unit, in addition to standard code requirements.
- Will my existing panel handle new basement circuits?
- It depends on your panel’s current capacity and load. We assess this as part of every basement wiring quote and recommend a panel upgrade if the new circuits need it.
- Can you wire a basement bathroom or kitchenette?
- Yes, we run the dedicated circuits and GFCI protection required for basement bathrooms, kitchenettes, and laundry hookups as part of the rough-in.
- Should electrical rough-in happen before or after framing?
- Rough-in wiring happens after framing but before drywall, so we can run wiring through open stud cavities and coordinate with your other trades on timing.
- How much does basement electrical wiring cost?
- Cost depends on the size of the basement, the number of circuits and fixtures needed, and whether it’s a standard finish or a legal second suite with additional requirements. We provide a clear quote after reviewing your plans.
