Electricians in Scarborough
Scarborough's sprawling mix of 1960s–1970s split-levels and newer subdivisions means widespread aluminum wiring concerns, aging panels, and growing demand for EV charger and home office electrical upgrades.

Electrical Considerations for Scarborough
Many 1960s-70s split-level homes in Agincourt and Scarborough Village were built with aluminum wiring, which requires special anti-oxidant connectors or full copper rewiring to meet current ESA standards and reduce fire risk.
Wartime and early post-war housing in West Hill and Highland Creek often has undersized 60-100A panels that cannot support modern electrical loads; upgrading to 200A service typically costs $2,200-$4,200 and requires Toronto Hydro coordination for the meter base.
Basement apartment conversions are extremely common across Scarborough, and each secondary suite requires its own dedicated sub-panel, smoke/CO detection circuits, and separate metering to comply with City of Toronto second suite bylaws and the Ontario Electrical Safety Code.
Aging underground electrical services in Guildwood-area homes can develop insulation breakdown and moisture intrusion over decades, often requiring a complete service lateral replacement coordinated between your licensed electrician and Toronto Hydro.
High-density townhouse developments near Scarborough Town Centre place heavy demands on shared infrastructure; EV charger installations in these complexes require load management systems and often condo board approval before ESA inspection can proceed.
Rouge and Malvern neighbourhoods feature large 1980s detached homes that were wired for the era's modest electrical needs; adding central air, EV charging, and home office circuits simultaneously often pushes these homes past their panel capacity, triggering a full service upgrade.
Permits & Regulations
All electrical work in Scarborough falls under the City of Toronto Building Division for building permits and the Electrical Safety Authority (ESA) for electrical permits and inspections. Any work beyond simple device replacements — including panel upgrades, new circuit installations, aluminum wiring remediation, EV charger wiring, and basement apartment electrical — requires an ESA permit. Your licensed electrician files the permit through ESA's online portal, and inspections are typically scheduled within 5-10 business days of the request. For basement apartment electrical upgrades, which are particularly common in Scarborough, you will also need a building permit from the City of Toronto Building Division to ensure the secondary suite meets Ontario Building Code requirements for egress, fire separation, and smoke detection circuits. The city's second suite program has specific electrical requirements including arc-fault circuit interrupter (AFCI) protection and interconnected smoke alarms on dedicated circuits. Toronto Hydro must be contacted separately for any work involving the electrical service entrance, meter base relocation, or service size upgrades. Toronto Hydro's connection process for upgrading from 100A to 200A service typically takes 4-8 weeks from application to energization. All construction activity must comply with Toronto's noise bylaws: Monday to Friday 7 AM to 7 PM, Saturday 9 AM to 7 PM, with no work permitted on Sundays or statutory holidays.
About Scarborough
Scarborough's housing stock spans four decades of rapid suburban growth, from the wartime bungalows of West Hill to the sprawling 1980s subdivisions of Rouge and Malvern. This diversity creates a wide spectrum of electrical challenges. The 1960s-70s split-levels and raised ranches that define neighbourhoods like Agincourt, Scarborough Village, and Highland Creek were commonly wired with aluminum branch circuits — a practice abandoned in the late 1970s due to fire risk. Today, these homes represent a significant portion of electrical upgrade demand across the area, whether through full copper rewiring or approved aluminum-copper pigtailing. Scarborough is also the epicentre of Toronto's basement apartment boom. Secondary suites have become essential housing in the area's detached and semi-detached homes, and the City of Toronto's second suite program has formalized the electrical requirements. A legal basement apartment demands its own sub-panel, dedicated appliance circuits, AFCI protection, and interconnected life safety systems — work that must pass both city building inspection and ESA electrical inspection. Electricians working in Scarborough handle these conversions routinely. The area's transformation continues with intensification along major corridors like Eglinton East and Kingston Road, new transit-oriented developments near Scarborough Town Centre, and the growing demand for EV charging infrastructure in both established neighbourhoods and new townhouse complexes. Toronto Hydro has been investing in grid infrastructure across Scarborough to support this growth, but individual homeowners must still ensure their own service entrance and panel can handle increased loads.
Frequently Asked Questions: Scarborough Electrical Services
How much does it cost to replace aluminum wiring in a Scarborough split-level home?
Full aluminum wiring replacement in a typical Scarborough split-level runs $9,000-$18,000 depending on the home's size and accessibility. A 1,200-square-foot split-level with reasonable attic and crawlspace access falls toward the lower end, while larger homes or those with finished walls requiring extensive fishing typically approach $14,000-$18,000. An alternative is aluminum-to-copper pigtailing using approved Alumiconn connectors at every outlet, switch, and junction box, which costs $3,500-$6,000 but must be done by an ESA-licensed electrician. Both options require an ESA permit and inspection.
What electrical upgrades are required for a legal basement apartment in Scarborough?
A legal basement apartment requires a dedicated sub-panel (typically 60-100A, costing $1,500-$2,800 installed), separate circuits for kitchen appliances, bathroom, and laundry, AFCI-protected bedroom circuits, interconnected smoke and CO alarms on dedicated circuits, and tamper-resistant receptacles throughout. The total electrical scope for a basement apartment conversion typically runs $4,500-$9,000. You'll need both a City of Toronto building permit and an ESA electrical permit, and the work must be completed by a licensed electrical contractor.
How long does a panel upgrade take in Scarborough, and will I lose power?
A standard 100A-to-200A panel upgrade in Scarborough takes 6-10 hours of on-site work and costs $2,200-$4,200. You will lose power for 4-6 hours while the electrician swaps the panel and Toronto Hydro reconnects the service. Toronto Hydro requires 4-8 weeks advance notice for service upgrades, so plan accordingly. Your electrician handles the ESA permit and coordinates the Toronto Hydro disconnect/reconnect. In some Guildwood and West Hill homes with underground services, additional time and cost ($800-$2,000) may apply if the service lateral needs replacement.
Can I install an EV charger in my Scarborough townhouse?
Yes, but townhouse EV charger installations in Scarborough require careful planning. A Level 2 charger installation costs $1,800-$3,200 depending on the distance from your panel to the parking area and whether your panel has capacity for a dedicated 40-50A circuit. Many Scarborough Town Centre-area townhouse complexes require a load management system ($500-$1,200 additional) to prevent overloading shared infrastructure. If you're in a condo townhouse, you'll need board approval and potentially an electrical engineer's assessment. Your electrician pulls the ESA permit, and installation typically takes one day.
My Scarborough home still has a fuse box — should I upgrade to a breaker panel?
Absolutely. Fuse boxes in Scarborough homes are typically 60A, which is dangerously inadequate for modern electrical loads. Upgrading to a 200A breaker panel costs $2,200-$4,200 and is one of the highest-value electrical improvements you can make. Beyond safety, a modern panel supports EV charger installation, central air conditioning, and basement apartment conversions. Insurance companies increasingly surcharge or decline coverage for homes with fuse boxes, so the upgrade often pays for itself through reduced premiums within 3-5 years. The work requires an ESA permit and Toronto Hydro coordination for the meter base swap.
