Licensed Commercial Electrical Contractor Serving Southern Ontario

Downtime costs your business money the moment the lights go out, so we plan work around your operating hours where possible, and respond within the hour when it can't wait. Every commercial project starts with a written scope, an itemized quote, and a real timeline you can build your operational plan around.

We handle retail, industrial, agricultural, and multi-tenant properties.. Fully licensed (ECRA/ESA 7016060), fully insured for commercial and industrial work, and a Verified Municipal Vendor for Norfolk County.

Renovations

Commercial Renovation Electrical for Retrofits, Expansions & Tenant Improvements

Commercial renovations get the same up-front planning as new construction, with the added challenge of working around an existing operation. We phase the work to keep your business running where possible, and schedule after-hours or weekend blocks when live work isn't safe or practical.

Common commercial renovation work

  • Tenant fit-outs and leasehold improvements
  • Retail space buildouts (lighting, POS wiring, signage circuits)
  • Office renovations (open plan wiring, workstation power/data, conference AV)
  • Restaurant electrical (hood systems, appliance circuits, dedicated equipment power)
  • Warehouse and industrial retrofits
  • Multi-tenant building upgrades
  • Lighting retrofits (LED conversion, occupancy sensors, dimming systems)

Panel Upgrades

Single-Phase and Three-Phase Panel Upgrades for Ontario Businesses

Growing operations outgrow their electrical service. New equipment, expanded HVAC, EV charging stations, backup power, or additional tenants all push a panel past what it was built to handle. We calculate the current load, size the upgrade to your projected growth, coordinate with your utility for the service disconnect, and phase the changeover to minimize downtime.

Commercial panel work

  • Single-phase service upgrades (200A, 400A, 600A)
  • Three-phase service installation and upgrades
  • Distribution panel and subpanel installation
  • Motor control center (MCC) installation
  • Automatic transfer switch integration for backup power
  • Meter base and service entrance replacement
  • Panel relocations for space reconfiguration

Maintenance

Scheduled Commercial Electrical Maintenance & Service Contracts

Electrical failures rarely happen without warning. Loose connections heat up. Panels arc. Motors draw more current as they age. Scheduled maintenance catches those problems while they're still repairs instead of shutdowns. We offer preventative maintenance for commercial clients on annual or semi-annual schedules, plus emergency response for anything that goes down between visits.

Included in commercial maintenance

  • Thermal scanning of panels and connections
  • Generator startup and load testing
  • Emergency lighting battery checks
  • Documentation for insurance and compliance
  • Priority scheduling for emergency callouts

  • Commercial standby generators
  • Automatic transfer switch installation
  • Load-shedding controls
  • Fuel system installation coordination

  • Solar-integrated battery storage
  • Peak shaving and demand charge management
  • UPS integration for data and control systems
  • Grid-interactive and off-grid modes

  • Solar carport and canopy structures
