Superior Power Electric
Markham's Trusted Electrician
Markham is one of the largest cities in York Region, with a population that has grown steadily over the past three decades. The city's housing ranges from heritage homes in Unionville and Markham Village to massive subdivisions built in the 2000s and 2010s across Cornell, Wismer, Cathedraltown, and Box Grove.
The older areas of Markham - Unionville's Main Street, Markham Village, and the established neighbourhoods near Highway 7 and McCowan Road - have homes dating back to the 1960s and 1970s. These properties have 100-amp panels, and some built between 1965 and 1975 have aluminum branch wiring that needs attention.
Markham's newer subdivisions are a different story. Homes in Cornell, Wismer, Cathedraltown, and Box Grove were built with 200-amp panels and modern copper wiring. But builder-grade electrical work leaves homeowners wanting more - pot lights instead of basic fixtures, EV charger circuits, dedicated home office power, and smart home integration.
The tech-savvy population in Markham drives higher-than-average demand for smart home electrical work. Home automation systems, smart panels, whole-home networking, and EV charger installations are common requests from Markham homeowners who want their homes to match the technology they use every day.
From our Brampton base, we reach Markham within 55 minutes via Highway 407 or Highway 7. We schedule Markham jobs in dedicated blocks to keep our response times consistent and minimize windshield time.

Common Electrical Issues
in Markham
Builder-Grade Electrical in New Subdivisions
Markham's newer subdivisions were built with minimum-standard electrical work. Homeowners quickly discover they need more pot lights, additional outlets, EV charger circuits, and dedicated power for home offices. These upgrades are straightforward in modern homes but should be done by a licensed electrician to maintain warranty and insurance coverage.
Learn MoreAging Panels in Established Areas
Markham's 1960s and 1970s homes near Highway 7 and McCowan Road have panels that are 50 to 60 years old. Many are at or beyond their rated lifespan. A 100-amp panel that was fine for two window air conditioners and a few appliances cannot support an EV charger, central air, and a home office.
Learn MoreEV Charging for Multi-Vehicle Households
Many Markham households have two or more vehicles, and the shift to electric is creating demand for multi-charger installations. Even a 200-amp panel can struggle with two Level 2 chargers running simultaneously. Load management and smart charging solutions are becoming standard.
Learn MoreHeritage Property Constraints
Unionville and Markham Village have heritage designation requirements that affect how electrical work can be done on the exterior of buildings. Interior upgrades are straightforward, but any visible exterior changes may need municipal approval in addition to ESA permits.
