How to Hire a Electrician in Ontario
Electrical work is one of the most regulated trades in Ontario for good reason — mistakes can cause fires, electrocution, or void your home insurance. Here is how to make sure you hire a qualified electrician every time.
Hiring Checklist
Red Flags to Watch For
Not ESA/ECRA licensed
This is non-negotiable. Unlicensed electrical work is illegal in Ontario and your insurance will not cover any resulting damage.
Says permits are not needed
Almost all electrical work beyond replacing a light switch requires an ESA permit. If they say otherwise, find someone else.
No written quote
Electrical jobs can escalate quickly. A detailed written quote protects both parties.
Wants to skip the ESA inspection
Inspections ensure safety and code compliance. Skipping them puts your family at risk.
Cash-only, no receipt
This usually means they are not reporting income and may not carry proper insurance.
Cannot explain what they will do
A good electrician can explain the work in plain language. If they cannot, they may not fully understand the job.
Questions to Ask Before Hiring
“What is your ESA/ECRA licence number?”
“Will you pull the ESA permit?”
“Is my panel adequate for this work?”
“What is included in your warranty?”
“How will you handle the ESA inspection?”
Licensing: Electrical Safety Authority (ESA)
Every electrical contractor in Ontario must hold an ECRA/ESA licence. The Electrical Safety Authority maintains a public registry where you can verify any contractor. Hiring an unlicensed electrician is not just risky — it is illegal, and any resulting damage may not be covered by your home insurance.
