Wired with Precision. Powered by Integrity
We don’t just wire homes.

Do I need a permit for electrical work or EV charger installation?
In most cases, yes. Electrical work in Ontario—including EV charger installations, panel upgrades, and backup power systems—requires a permit and an Electrical Safety Authority (ESA) notification. A licensed electrical contractor is responsible for filing the required paperwork and arranging inspections to ensure the work meets Ontario safety and compliance standards.
Are GenerLink systems legal in Ontario?
Yes. GenerLink systems are legal in Ontario when installed by a Licensed Electrical Contractor and approved by the Electrical Safety Authority (ESA). The installation must meet Ontario Electrical Safety Code requirements and be inspected to ensure it is safe, properly connected, and compliant with provincial regulations.

Frequently Asked Questions
How Much Does an Electrician Cost in Kingston?
You’re not alone in asking this — and we believe you should have a clear idea of pricing before you even pick up the phone.
While every job is different, here’s a quick breakdown of what most homeowners in Kingston can expect:
🔧 Service Calls
If you already know what you need (like a panel upgrade or EV charger), we offer a free quote visit.
If something isn’t working and needs diagnosing:
$170 for the first 15–30 minutes
$260 for the first 30–60 minutes
In many cases, the issue is resolved during the same visit.
EV Charger Installation
One of our most common services — pricing depends mainly on distance from your panel:
Starts at $995 (within 5 feet)
Can go up to $3,495 depending on installation complexity
⚠️ Important to Know
If your home has an older panel (like a fuse panel or Federal Pioneer), a panel upgrade may be required:
Panel replacement: starting around $4,000
Service upgrade: starting around $3,000
Good news:
In many cases, troubleshooting and repairs can be completed in the same visit — meaning the initial diagnostic fee often covers the full job.
View the full pricing breakdown →
What services do you offer?
We provide a full range of electrical services including EV charger installation, panel upgrades, lighting design, home wiring, surge protection, and troubleshooting. We serve both homeowners and businesses across Kingston and surrounding Ontario areas.
What if I have an electrical emergency?
If you experience an electrical emergency, contact us right away. We offer prompt emergency service for urgent issues like power loss, tripped breakers, or faulty wiring.
Are you licensed and insured?
Yes. Wieser Electric is a fully licensed and insured electrical contractor. Our electricians are certified and trained to meet all Ontario Electrical Safety Code standards.
Do I need a permit for electrical work or EV charger installation?
In most cases, yes — but don’t worry. Wieser Electric handles all necessary permits and inspections to ensure your installation meets Ontario safety and compliance standards.
Do you service both residential and commercial properties?
Yes — with a clear focus.
Wieser Electric primarily serves homeowners and specialises in EV charger installations, panel upgrades and service changes, whole-home battery systems, and electrical safety upgrades.
On the commercial side, we selectively take on smaller projects and EV-related work, including jobs for professional offices, retail spaces, and property management companies when the scope aligns with our expertise. We do not pursue industrial or large-scale commercial facilities, and we’re not positioned as a lowest-bid provider.
Our goal is simple: deliver high-quality, well-planned electrical work for clients who value safety, reliability, and long-term solutions.
Can a landlord replace a light fixture in my rental?
No. Any electrical work in a rental must be done by a Licensed Electrical Contractor who files a Notification of Work with ESA.
What if my landlord says it’s a "small’ job?
Small jobs can still be dangerous. Improper work creates fire and shock risks. Ask for documentation and contact an LEC if unsure.
Electrical Problems Homeowners Accidentally Create (And How to Avoid Them)?
Nobody sets out to create an electrical problem in their home. It happens gradually — a shortcut here, a YouTube tutorial there — until one day something stops working, or worse, something starts burning. (My wife fixed our washing machine when we were posted to Winnipeg, so I know YouTube works! Just maybe think twice about your household electrical?)
This isn’t about blame. It’s about helping you recognise the patterns we see repeatedly in Kingston homes so you can avoid them.
The most common self-inflicted electrical problems we find:
Overloaded circuits from power bars and extension cords Power bars are convenient. They’re also one of the leading causes of electrical fires. The problem isn’t the bar itself — it’s plugging high-draw appliances (space heaters, coffee makers, mini-fridges) into a bar that was designed for lamps and phone chargers. One circuit has a limit. When you exceed it repeatedly, the wiring inside your walls gets warm. Then warmer. Then you have a problem that a power bar didn’t cause, but quietly encouraged.
DIY wiring that was “good enough” — until it wasn’t We find DIY electrical work in roughly one in four older Kingston homes we inspect. Some of it is fine. A lot of it isn’t — not because the homeowner wasn’t trying, but because residential wiring has specific code requirements that aren’t obvious to someone without training. Reversed polarity, connections made with the wrong wire gauge, missing junction box covers. These don’t always cause immediate problems. They cause eventual ones. I’m not sure if it’s a trade term or not, but, when we come across a home with dubious wiring, internally, we call it a “Homeowner’s Special”. Unfortunately, it’s usually the previous homeowner that did it, or, maybe even two homeowners ago, and the current home owner is now responsible for it.
Ignoring a breaker that keeps tripping A breaker that trips once is doing its job. A breaker that trips every few weeks is trying to tell you something. The most common response we see: flip it back and move on. The circuit is overloaded, or there’s a fault somewhere downstream. Resetting a breaker that keeps tripping doesn’t fix the problem — it just resets the clock.
Painting over or covering smoke detectors Ontario’s Fire Code requires working smoke detectors on every level of your home. What it can’t require is that you keep them clean and uncovered. Painted-over detectors, detectors buried under insulation in a renovation, detectors with dead batteries left unchecked — all of these create the appearance of compliance without the protection. We’ve even seen a cover still on a smoke detector, the one used to protect it from construction dust, a year after the construction was over.
Adding heavy loads without checking panel capacity Hot tubs. EV chargers. Heat pumps. Basement suites. Every one of these adds significant electrical demand to your home. The problem comes when homeowners — or contractors who should know better — add them without first calculating whether the existing panel can handle the load. On a 100 Amp service already carrying a stove, dryer, and air conditioner, there may be as little as 15 Amps of room left. That’s not enough for a Level 2 charger. It’s not enough for a hot tub. Adding them anyway creates an overloaded service that fails — sometimes dramatically.
The honest bottom line: None of these problems make you a bad homeowner. They make you a normal one. Most of us were never taught what our electrical system actually needs. The fix isn’t guilt — it’s information. And now you have some.
If any of these scenarios sound familiar, a professional inspection is the fastest way to know where you stand. We’ll tell you exactly what we find, what matters, and what can wait.
What Can Go Wrong If I Hire the Wrong Electrician?
The cheapest quote isn’t always the best deal. In residential electrical work, the gap between a properly done job and a shortcut job often isn’t visible — until it becomes a very expensive problem.
Here’s what we see regularly when we’re called in to fix or inspect work done by others.
No permit pulled In Ontario, almost all electrical work requires an Electrical Safety Authority (ESA) Notification of Work — what most people call a permit. When a contractor skips this step, they save themselves some paperwork. You absorb all the risk. If an electrical fire occurs and the investigation finds unpermitted work, your insurance company has grounds to reduce or deny your claim. When you go to sell your home, a buyer’s inspector can flag missing permits and use that as negotiating leverage — or a reason to walk. The contractor is long gone. You’re left holding it.
Work that doesn’t meet current Ontario code Electrical code gets updated. What was acceptable wiring practice in 1995 may not meet today’s standard. A Licensed Electrical Contractor keeps current. An unlicensed one — or a licensed one who cuts corners — may wire your home to an outdated standard and never mention it. The Certificate of Acceptance from the ESA exists precisely to confirm that work meets current code. If your contractor didn’t get one, you don’t have that confirmation.
Disappeared after the job We’ve had homeowners call us because the electrician they hired six months ago won’t return calls. The work has a problem. There’s no warranty in writing. And the contractor’s phone number goes to voicemail. A contractor who’s serious about their reputation puts their name permanently on every job they do — because they expect to still be in business when you call.
Messy work that creates future problems Electrical work that’s done sloppily isn’t just an aesthetic issue. Wires that aren’t properly secured, connections that aren’t tight, panels that are overcrowded and unlabelled — these create conditions for future failures. We’ve opened panels where we genuinely couldn’t tell what circuit controlled what. That’s not a minor inconvenience. In an emergency, it matters.
The contractor who said you didn’t need a panel upgrade — but you did This one is subtle. Sometimes a contractor will tell you your existing panel is fine to avoid delivering unwelcome news. Sometimes they genuinely don’t know. Either way, adding a high-demand load like an EV charger or hot tub to a panel that can’t safely support it creates an overloaded service. The panel doesn’t always fail immediately. It fails gradually — and usually at an inconvenient moment.
What to look for when hiring: A Licensed Electrical Contractor (ECRA/ESA licensed in Ontario) who pulls permits, files ESA notifications, and provides a Certificate of Acceptace on applicable work. Ask for it specifically. A contractor who hesitates is telling you something important.
What Electrical Problems Are Common in Older Kingston Homes?
Kingston is a beautiful city with a housing stock that reflects its age; limestone homes built in the 1800s, brick houses from the postwar boom. Mid-century bungalows that have been renovated three times by three different owners with three different ideas about what “good” looks like.
The electrical systems in these homes tell the story of every era they’ve lived through. And some of those stories have some concerning chapters.
Knob-and-tube wiring If your home was built before roughly 1950, there’s a real chance you have some knob-and-tube wiring still active somewhere. This isn’t automatically a crisis — knob-and-tube was the standard of its day and was installed with reasonable safety margins for the electrical loads of that era.
The problem is what’s happened since. Knob-and-tube was designed for homes with a few lights and maybe an icebox. Not for homes with EV chargers, heat pumps, home offices, and entertainment systems. It also has no ground wire, which means it doesn’t play well with modern three-prong appliances. And when it’s been buried under insulation — which kills its ability to dissipate heat — it becomes a genuine fire risk.
Many insurance companies in Ontario will no longer insure homes with active knob-and-tube wiring, or will charge significantly higher premiums. If you’re not sure whether you have it, an inspection could tell you, but, you don’t really know with 100% certainty unless you open up the walls. I was talking to a city inspector in Hamilton recently about AirBnB’s and they require a Licensed Electrical Contractor to certify that the home has no knob-and-tube. I don’t know of any Licensed Electrical Contractor willing to sign their company away like that. Needless to say, there are likely a lot more whole home rewire’s going on in Hamilton.
Aluminum wiring In the late 1960s and through the 1970s, aluminum wiring was used as a cost-saving alternative to copper in many Canadian homes. It works — with specific precautions. The problem is that aluminum expands and contracts more than copper, which loosens connections over time. Loose connections arc. Arcing causes fires.
Aluminum wiring isn’t automatically dangerous, but it requires compatible outlets, switches, and connections. The fix isn’t always full rewiring — sometimes it’s a process called pigtailing, where aluminum-rated wire connectors are installed at each connection point. But it requires assessment by someone who knows what they’re looking at.
Federal Pioneer and Stab-Lok panels These panels were installed in thousands of Canadian homes from the 1950s through the 1980s. They have a documented history of breakers failing to trip when they should — which means the safety mechanism designed to prevent overloads and fires doesn’t always work. In one case that I’ve personally seen in Kingston, it couldn’t trip because the breaker was completely melted.
If your home has a Federal Pioneer panel with Stab-Lok breakers, replacement isn’t optional — it’s a matter of when. Actually, it is optional, but, perhaps it shouldn’t be.
Under-sized services A 60 Amp service was adequate for a home in 1965. It is not adequate for a home in 2026. If your home still has a 60 Amp service — identifiable by a small meter base and older wiring coming in from the street — you’re running a modern household through infrastructure designed for a fraction of today’s electrical demand. The solution is a service upgrade to 100 or 200 Amps, which also involves the meter base, mast, and ESA inspection. Even 100 Amps doesn’t make a lot of sense, I typically recommend 200 Amps if at all possible.
Multiple generations of DIY renovation wiring Kingston has a lot of homes that have passed through many hands. Each owner may have added a circuit, finished a basement, or wired a garage the way they thought made sense. The result is sometimes a panel that tells a complicated story — circuits that aren’t labelled, breakers that are doubled up, junction boxes buried inside finished walls. None of this is unfixable. But it requires someone who can read what’s actually there, not just what the panel door says.
The honest takeaway: Older homes have character. They also have history — and some of that history is in the walls. An electrical inspection isn’t about finding reasons to spend money. It’s about knowing what you actually have, so you can make informed decisions about what comes next.
What Should I Know Before Scheduling an EV Charger Installer?
EV charger installation looks straightforward from the outside. Run a wire, mount a box, plug in the car. Done.
The reality is more involved — and the problems that arise usually come from one of a handful of predictable places. If you’re planning an EV charger installation, this page will help you understand the risks so you can ask the right questions before anyone starts work.
The panel that can’t support the load This is the most common issue we encounter. A Level 2 EV charger requires a dedicated 50 – 60 Amp circuit. Your panel has a total capacity — 100 Amps or 200 Amps for most Kingston homes — and your existing appliances are already using a good portion of it.
A home with a stove, dryer, and central air conditioning has a calculated demand load of roughly 85 Amps. On a 100 Amp service, that leaves approximately 15 Amps available. That’s not enough for a Level 2 charger.
The fix is either a panel upgrade or a charger with load management — but the point is, this has to be calculated before installation, not discovered mid-job. We do a demand load calculation on every EV charger quote. It’s not optional.
The distance problem Our pricing is based on the distance from your electrical panel to your charger location. What surprises some homeowners is how that distance is measured. Wire doesn’t travel in straight lines. It runs up walls, across joists, through conduit, and around obstacles. A charger that looks like it’s 20 feet from your panel might require 60 feet of wire by the time we route it properly and to code.
Outdoor installations and weatherproofing Installing a charger outside — on an exterior wall, in an exposed carport, or at the end of a laneway — requires specific weatherproof equipment and proper conduit. Ontario winters are not gentle. An outdoor installation done without the right enclosures and fittings will fail. Sometimes immediately. Sometimes after two winters.
Underground runs Some installations require running conduit underground — across a driveway, through a yard, or to a detached garage. This involves trenching, specific burial depths, correct conduit type, and in some cases cutting and patching asphalt. It’s more involved than an interior installation, and the cost reflects that. A quote that doesn’t account for underground work upfront will have a very different final invoice.
No permit pulled An EV charger installation in Ontario requires an ESA notification. Full stop. A contractor who installs your charger without filing that notification is saving themselves paperwork and passing the regulatory risk to you. If your charger ever causes an issue and the ESA finds no notification on record, your insurer gets involved — and not in your favour.
Every Wieser Electric EV charger installation includes an ESA notification of work and a Certificate of Acceptance. That’s not an upsell. It’s the job.
The wrong charger for your vehicle Most Level 2 chargers work with most EVs — but not all. Tesla vehicles, for example, use a different connector standard in North America (NACS, now being adopted more broadly). We’re Kingston’s only Tesla Wall Connector Authorised Installer (since 2018 as a matter of fact!). That matters if you drive a Tesla, because an unauthorised installation may void your warranty or create compatibility issues. Using a Tesla Certified Installer ensures proper commissioning through the Tesla One App.
If you drive — or plan to drive — a Tesla, ask specifically about authorised installation before you book anyone.
The honest summary: EV charger installation done right is a clean, straightforward job. The problems listed above are all avoidable — with the right contractor, the right process, and the right conversation before work begins. If you’ve got questions about your specific situation, we’re happy to walk through it with you before you commit to anything.

Quality Over Cut Corners
$40 Pot Lights (Installed!)
That’s not us—please don’t call if that’s what you’re looking for.
We’re sure you got a great deal from the unlicensed, uninsured number you found on a flyer stapled to a streetlight pole in Mississauga or Brampton. But that’s not how we do business.
At Wieser Electric, we are fully licensed and insured. We pull electrical permits and ensure every installation is inspected and approved by the Electrical Safety Authority (ESA), with a Certificate of Acceptance provided for your records.
We get a lot of calls from people shopping around, asking only for the price per pot light. But there’s more to a quality installation than just the number. For example:
How do you want the lights switched? Do you want all the lights on a single switch, or do you prefer different zones—like accent lighting around the room or separate controls for the area over your TV?
Thoughtful planning makes a big difference in how you enjoy your space.
So if you’re just hunting for the cheapest pot light install—don’t call us. But if you’re looking for professional work, done right, and with safety and quality in mind, we’d love to talk.
(And hey—if you do find someone doing great work at that $40 price point, let us know. We’d love to meet them.)
