People use “electrical contractor” and “electrician” as if they mean the same thing. In Ontario they do not — and the difference decides who is legally allowed to take your money for electrical work. Here is what actually separates the two, and how to hire the right one.
An electrician is a certified person who performs electrical work. An electrical contractor is a licensed business that is legally allowed to be hired for that work under Ontario law. Only a Licensed Electrical Contractor (LEC) can contract with you.
In Ontario, a certified electrician holds a 309A Construction and Maintenance Electrician Certificate of Qualification, issued through Skilled Trades Ontario after a full apprenticeship and provincial exam.
The 309A proves the person is qualified. It does not give them the right to run a business.
A Licensed Electrical Contractor is a business that holds a 7-digit ECRA/ESA licence issued by the Electrical Safety Authority. To hold the licence, the LEC must:
The LEC is the only entity in Ontario that can legally advertise, quote, or be paid for electrical work.
Hiring an individual electrician instead of an LEC is a common and expensive mistake. Without the LEC:
For any permitted job — like a panel upgrade, service upgrade, or new circuit — the ESA permit must be tied to the LEC’s licence. You cannot legally get that from an individual electrician on the side.
Before signing anything:
A company can print “electrical contractor” on a truck without actually holding an ECRA/ESA licence, so the title alone tells you nothing. What matters is whether the business appears in the ESA registry under that exact licence number, whether a Master Electrician is designated on file, and whether the $2,000,000 liability insurance is current. A legitimate LEC will hand you that information without hesitation, because it is public record and they check it themselves before every job.
When you hire a Licensed Electrical Contractor, you are hiring the full chain: a Master Electrician taking code responsibility, certified 309A electricians doing the work, and ESA inspecting it. That is what protects your home, your insurance, and the resale value of the property.
No. An electrician is a certified 309A tradesperson who does the work. An electrical contractor is a business licensed by ECRA/ESA to be hired for that work. In Ontario, only the contractor (LEC) can legally contract with you.
Not legally in Ontario. A certified 309A electrician must be employed by a Licensed Electrical Contractor. Hiring an individual directly means no ESA permit, no inspection, and no Certificate of Acceptance.
Ask for their 7-digit ECRA/ESA licence number and look it up on the ESA Find a Contractor tool at esasafe.com. Confirm it is active and note the designated Master Electrician.
ESA requires at least $2,000,000 in public liability and property damage insurance to hold an ECRA/ESA contractor licence. Most reputable LECs also carry WSIB coverage.
Yes, for most residential work — panel upgrades, service upgrades, new circuits, rewires. Your LEC pulls the ESA notification, schedules the inspection, and delivers the Certificate of Acceptance when the job passes.
