What Legally Needs a Licensed Electrician in Ottawa
One of the most common things we do is tell people a job is not ours. This page explains where the line sits in Ontario, so you know what to ask for before anyone quotes you.
The line, in one paragraph
In Ontario, electrical work performed for hire is regulated. The Electrical Safety Authority sets the safety framework, and contractors doing electrical work for others must be licensed through ECRA/ESA. The practical distinction most homeowners need is between replacing something that already exists on an existing circuit and adding, extending or altering the wiring itself. The first is generally maintenance. The second is licensed work, and it usually requires notification to the ESA.
This page is a plain-English orientation, not legal advice, and the rules do change. For anything you are unsure about, the ESA is the authority — not a contractor's opinion, including ours.
Roughly where jobs fall
Generally ours
Handyman work
- · TV mounting and cable routing
- · Bathroom fan ducting and the ceiling opening
- · Faucet, toilet and fixture swaps
- · Doors, locks, hardware, trim
- · Drywall, ceilings, tile, caulking
- · Grab bars, shelving, assembly
- · Smart thermostats (24V)
- · Smart locks, cameras, sensors
Depends on what's behind it
Ask first
- · Like-for-like light fixture swap
- · Replacing an existing exhaust fan
- · Smart thermostat on existing wiring
- · Video doorbell on an existing transformer
- · Replacing a switch or receptacle cover
- · Video doorbell (transformer capacity is the catch)
If the wiring is old, unusual, or nothing matches what should be there — it goes to an electrician.

Common questions
Can a handyman install a light fixture in Ontario?
Swapping an existing fixture for a new one on the same circuit is generally treated as maintenance rather than new electrical work, and many handymen do it. Anything that adds, extends or alters a circuit is licensed work. We are conservative on this line — if there is any doubt about what is behind the box, we hand it over.
What does ECRA/ESA licensed actually mean?
The Electrical Safety Authority administers electrical safety in Ontario, and the Electrical Contractor Registration Agency licenses the contractors permitted to do electrical work for hire. A legitimate electrical contractor has an ECRA/ESA number and will give it to you without hesitation. Ask for it.
Does a bathroom exhaust fan need an electrician?
If you are replacing an existing fan with one that uses the same circuit and the same wiring, that is generally a like-for-like swap. If it needs new wiring, a new switch leg, or the old unit was hardwired differently, that is licensed work. Fan ducting and the hole in the ceiling are ours; the connection may not be.
Do I need a permit to add an outlet?
New circuits and most alterations require notification to the ESA, and the licensed contractor doing the work handles that. If someone offers to add an outlet without any mention of notification, that is a signal worth paying attention to.
Will unpermitted electrical work affect my home insurance?
It can. Insurers may investigate the cause of a fire and the presence of unpermitted work is a fact they will find. It also surfaces during a sale, when a buyer's inspector notices something that does not match the paperwork. This is the practical reason to do it properly, separate from the safety one.
Can you mount a TV if there is no outlet behind it?
We can mount the TV and route the low-voltage cabling. A recessed outlet behind the TV is a new receptacle, which is a licensed electrician's job. We will tell you exactly what to ask for so you are not paying an electrician to work out the scope.
What about smart doorbells and smart thermostats?
Low-voltage devices replacing an existing low-voltage device are usually straightforward. Where it gets complicated is when the existing transformer cannot carry the new device, which is a real and common problem with video doorbells. That is where an electrician earns their fee.
Which smart home devices need an electrician?
The dividing line is voltage, not difficulty. Smart thermostats, video doorbells, smart locks, cameras, sensors and smart garage openers are low-voltage or battery — no licensed contractor needed. Smart light switches, dimmers and USB or USB-C receptacles are line-voltage devices, and in Ontario that is licensed work when someone is paid to do it. The irony is that the switch is often the easier job physically and the one you cannot hire us for.
Can you replace my outlet with a USB-C one?
No, and we would rather explain why than quietly do it. Replacing a receptacle is like-for-like work that does not need an ESA notification — but the notification question and the licensing question are separate. In Ontario, electrical work performed for hire needs a Licensed Electrical Contractor no matter how minor. A homeowner may do it in their own home; a contractor being paid for it is a different situation, and unlicensed electrical work can affect a fire insurance claim.
What about a smart thermostat — is that electrical work?
No. Thermostats run at 24 volts, not line voltage, so they sit outside the licensed electrical question entirely. The genuine obstacles are an older system with no common wire, or a transformer that will not carry the new unit. Both are things we check before starting rather than discover halfway.
And a video doorbell?
Also low voltage, and usually straightforward. The common failure is the existing chime transformer being too small for the new device — which is a real and frequent problem with video doorbells, and the point at which an electrician earns their fee.
Why would a contractor turn work down?
Because taking licensed work without a licence exposes you and them. A contractor who is happy to do anything you ask has either got a licence you have not seen, or is not thinking about what happens afterwards. It is worth knowing which.
Not sure which side your job is on?
Describe it. If it's ours we'll quote it, and if it isn't we'll tell you what to ask an electrician for — free either way.
