Frequently Asked Questions

Does electrical work require an ESA permit in Ontario?

Yes. In Ontario, electrical work including panel upgrades, new circuits, and EV charger installation must be permitted and inspected by the Electrical Safety Authority (ESA). Your electrician applies for the permit and arranges the inspection - always confirm they handle this before hiring.

What size panel do I need for an EV charger?

A Level 2 EV charger requires a 240V/40A dedicated circuit. If your existing panel is at or near capacity (below 200A service), a panel upgrade may be needed. An electrician can assess your current capacity during a site visit and confirm what is required.

How long does an electrical panel upgrade take?

Most residential panel upgrades take one full day. Your electrician will coordinate with your local utility and the ESA to schedule inspections. Power will be off for a portion of the day - plan accordingly and notify any tenants in advance.

How much does an electrical panel upgrade cost in Ontario?

A standard 200A panel upgrade in Ontario runs $2,500-$5,000 including parts, labour, and ESA permit fees. Older homes that need new circuits or main service line upgrades cost more. If your home still has a 60A or 100A panel, upgrading to 200A is often worthwhile before adding EV charging or other high-draw appliances.

What are the signs my electrical system needs upgrading?

Key warning signs include frequently tripped breakers, flickering lights when appliances run, a panel with fuses (not breakers), aluminum wiring (common in Ontario homes built in the 1960s-1970s), or not enough outlets for your needs. An electrician can inspect and recommend whether repair or upgrade is appropriate.

What should I ask an electrician before hiring them in Ontario?

Ask whether they handle ESA permits and inspections, get a written quote with scope and materials, confirm the warranty on labour, and verify their ESA contractor number. For larger jobs, ask for a timeline and whether power will be disrupted. Always get the permit inspection completed before paying the final invoice.

Does time of year affect electrical work timelines in Ontario?

Interior electrical work - panel upgrades, EV charger installation, circuit additions - happens year-round with no seasonal constraint. Outdoor work like exterior lighting, generator hookups, or service entrance upgrades is more practical in spring through fall. For planned panel upgrades, spring and fall typically have better contractor availability than mid-summer or mid-winter peak demand periods.
