Panel & Service Upgrades

An outdated or overloaded panel is one of the most common causes of tripping breakers, flickering lights and failed insurance inspections. We size, supply and install new panels and services to match how you actually use power today, including EV chargers, heat pumps, induction ranges and hot tubs.

Scope of work

  • Service upgrades: 60A/100A to 200A residential

What's included

  • Disconnect/reconnect scheduling with your utility
  • Clean, labelled panel and directory
  • ESA certificate of inspection for your records

Signs you may need an upgrade: breakers that trip often, warm or buzzing panel, a fuse box, no space for new circuits, or insurance asking about your panel's age or brand.

Electrical FAQ

Questions we hear often

Do I need a permit for electrical work in Ontario?

Most electrical work in Ontario, including panel changes, new circuits, EV chargers, basement wiring and renovations, requires a notification of work to the Electrical Safety Authority (ESA). Licensed electrical contractors file it, and ESA inspects the work. We take care of this on every job that requires it.

Do I need a 200 amp panel for an EV charger?

Not always. Many homes with 100A service can add a Level 2 charger after a proper load calculation, sometimes using an energy management system (EVEMS) that shares capacity with other loads. If your load calculation shows you need more capacity, we'll explain the options, including a 200A service upgrade.

How long does a panel upgrade take?

A typical residential panel replacement is completed in one day. A full service upgrade (for example 100A to 200A) also requires coordination with your utility for the disconnect and reconnect, and we schedule this for you.

Is knob-and-tube or aluminum wiring a problem?

Many insurers in Ontario will limit or refuse coverage on homes with active knob-and-tube wiring, and older aluminum branch wiring needs proper connections to prevent overheating. We can assess your home, quote replacement or remediation, and provide documentation for your insurer.

Can you wire a legal basement apartment?

Yes. Secondary suites have specific electrical and fire safety requirements, including interconnected smoke and CO alarms between units. We handle the suite's wiring, lighting, smoke/CO alarm interconnection and ESA permit, and can coordinate with your contractor and the building permit process.
