What Is an ESA Inspection and Why You Need One
If you鈥檝e had electrical work quoted in Ontario, you鈥檝e likely heard the term 鈥淓SA inspection.鈥� Here鈥檚 what it means and why it matters.
What is the ESA?
The Electrical Safety Authority (ESA) is the regulatory body responsible for electrical safety in Ontario. Most electrical installations and renovations require a permit and inspection to confirm the work meets the Ontario Electrical Safety Code.
When is an inspection required?
- New panel installations or upgrades
- New circuits or wiring (additions, basement finishing)
- EV charger installations
- Any work affecting your home鈥檚 main electrical service
Why it matters
- Safety 鈥� inspections catch code violations before they become fire or shock hazards.
- Insurance 鈥� many home insurance policies require proof of ESA compliance for electrical claims.
- Resale 鈥� buyers and lawyers often request ESA compliance certificates during a home sale.
Every job we complete includes the appropriate ESA permit and inspection as standard practice, not an upsell.
