The best electricians in Ottawa are Licensed Electrical Contractors (LECs) holding a valid ECRA/ESA licence number, staffed by Certified Master Electricians or 309A-certified journeypersons, and willing to take out an ESA notification for every job that requires one. In Ontario, electrical contracting is strictly regulated — only an ESA-licensed contractor may legally offer electrical work for hire — so checking the seven-digit ECRA/ESA number on the Electrical Safety Authority's public directory instantly separates real contractors from handymen. For 2026 budgeting, licensed Ottawa electricia...
Ontario requires anyone who does electrical work for hire to operate as a Licensed Electrical Contractor, and every LEC is issued a seven-digit ECRA/ESA licence number that must appear on their vehicles, quotes, invoices, and advertising. The Electrical Safety Authority maintains a free public directory where you can confirm a licence is active before you let anyone touch your panel. This is not a formality: unlicensed electrical work can void your home insurance, fail at the point of sale, and — most seriously — start fires. Alongside the contractor licence, individual electricians should hold a 309A Construction and Maintenance Electrician Certificate of Qualification, or be registered apprentices supervised by a certified journeyperson. Ask for the ECRA/ESA number in writing, verify it, and confirm general liability insurance and WSIB clearance. A licensed contractor will offer this information without hesitation; anyone who deflects the question or claims their work "doesn't need a permit" for panel or circuit work should be ruled out immediately.
A handyman may legally change a light bulb, but installing circuits, replacing panels, adding outlets, or wiring a hot tub is contractor territory in Ontario. Cheap unlicensed wiring is the most common reason Ottawa homeowners face costly ESA correction orders during a home sale.
Licensed Ottawa electricians generally charge $100–$160 per hour in 2026, often with a minimum service call of about $90–$150 for the first visit. Typical job pricing gives a more useful picture: adding a standard receptacle where wiring is accessible runs roughly $200–$400; installing a ceiling fixture or fan, about $200–$450; a dedicated 20-amp appliance circuit, about $350–$750 depending on the run; and replacing a failed breaker, roughly $175–$350. A 100-amp to 200-amp service upgrade — common in Ottawa's 1950s–1970s housing stock across Alta Vista, Elmvale Acres, and older Nepean — typically costs $2,800–$5,500 including the ESA notification and coordination with Hydro Ottawa, more if the mast, meter base, or underground service also needs replacing. Knob-and-tube or aluminum wiring remediation in century homes in the Glebe or Old Ottawa South can run $12,000–$30,000+ for a full rewire. A Level 2 EV charger install runs about $1,200–$2,800 depending on the distance from the panel and whether a load calculation shows spare capacity. Pot light installation is commonly $180–$300 per light in a finished ceiling.
Several insurers surcharge or decline homes with active knob-and-tube or unremediated aluminum branch wiring. If you own an older Ottawa home, an electrician's written assessment of the wiring type is useful documentation at renewal time as well as before a sale.
Electrical permits in Ontario do not come from the City of Ottawa — they come from the Electrical Safety Authority in the form of a notification of work, and an ESA inspector verifies the installation against the Ontario Electrical Safety Code. Notifications are required for essentially all new wiring and alterations: new circuits, panel and service upgrades, basement or addition wiring, hot tub and pool bonding, EV charger installs, and knob-and-tube or aluminum remediation. Simple like-for-like replacement of a light fixture or a switch generally does not require one. Your Licensed Electrical Contractor is responsible for filing the notification and arranging the inspection, and you should receive a Certificate of Acceptance when the work passes — keep it, because buyers, lawyers, and insurers ask for it. Note that larger projects may also need a separate City of Ottawa building permit for the construction work itself; the two processes are independent and both may apply to a basement finish or an addition.
Service upgrades require Hydro Ottawa to disconnect and reconnect the service, which has to be scheduled. A good contractor books this in advance and warns you about the outage window instead of discovering the requirement mid-job.
Beyond the licence, look at how the contractor works. A quality Ottawa electrician does a load calculation before adding a major load such as an EV charger, hot tub, or heat pump, rather than assuming the existing service can carry it. They label the panel directory legibly when they finish, use proper cable supports and box fill, install AFCI and GFCI protection where the current code requires it, and leave the work area clean. Their quote itemizes labour, materials, the ESA notification fee, and any drywall or finish exclusions, and it states a workmanship warranty — one to two years is typical, on top of manufacturer warranties on devices and panels. Communication is a strong signal: contractors who confirm appointments, arrive within the stated window, and explain findings in plain language tend to do the same quality of work behind the drywall. Reviews are useful when read for patterns, particularly around scheduling reliability, surprise charges, and how the company handled a callback.
Electrical is one of the cheapest trades to get right at rough-in stage and one of the most expensive to change later, so if you are renovating, bring the electrician in during design rather than after the drywall is up. A basement finish, kitchen remodel, or addition is the natural moment to add the dedicated circuits, pot lights, USB receptacles, exterior outlets, and EV-ready conduit you will want in five years. It is also the point to check whether your service capacity supports future electrification — heat pumps, induction ranges, and EV chargers all add load, and some federal and provincial retrofit incentives apply to electrification upgrades. Coordinate the electrical rough-in inspection with the plumbing and framing inspections so you are not waiting on sequential sign-offs, and confirm who is responsible for patching drywall after wiring runs, because electricians usually exclude finish repair. Sequencing this properly is one of the clearest ways to keep a renovation budget from drifting.
For anything larger than a service call, get three written quotes and put every bidder on the same scope. Ask each for their ECRA/ESA licence number, confirmation that an ESA notification is included in the price, the specific devices and panel brand being used, a load calculation where a major appliance is involved, the workmanship warranty, and what finish repair is or is not included. Verify each licence yourself in the ESA directory and confirm liability insurance and WSIB clearance. Compare the scopes before the prices — a quote that omits the ESA fee, the load calculation, or the drywall exclusion is not cheaper, just less complete. You can browse screened, licensed electrical contractors in our /directory and request free, no-obligation quotes through the quote form. Keep the Certificate of Acceptance and the final invoice together in your home file; they are the documents that prove the work was done legally when you sell or make a claim.
What is your ECRA/ESA number? Is the ESA notification included in this price? Will you do a load calculation? Who patches the drywall? What is your workmanship warranty, and how quickly do you respond to a callback?
The best Ottawa electricians work for Licensed Electrical Contractors with a valid, verifiable ECRA/ESA licence number, employ 309A-certified journeypersons or Master Electricians, file ESA notifications for all work that requires them, carry liability insurance and WSIB coverage, and provide itemized written quotes with a workmanship warranty. Verify the licence in the ESA public directory, then compare three written quotes on identical scope.
Licensed Ottawa electricians typically charge $100–$160 per hour in 2026, with a minimum service call fee of about $90–$150. Flat-rate pricing is common for defined jobs — for example, roughly $200–$400 to add an accessible receptacle or $180–$300 per pot light in a finished ceiling.
A 100-amp to 200-amp service upgrade typically costs $2,800–$5,500 in Ottawa in 2026, including the ESA notification and coordination with Hydro Ottawa for the disconnect and reconnect. Replacing the mast, meter base, or an underground service run pushes the cost higher.
Yes for essentially all new wiring and alterations — new circuits, panel and service upgrades, basement or addition wiring, hot tub and pool bonding, EV charger installs, and knob-and-tube or aluminum remediation. Electrical permits come from the Electrical Safety Authority as a notification of work, not from the City of Ottawa. Like-for-like fixture or switch swaps generally do not require one.
A Level 2 EV charger installation typically runs $1,200–$2,800 in Ottawa, depending on the distance from the panel, whether the run is surface-mounted or concealed, and whether a load calculation shows the existing service has spare capacity. If a service upgrade is required first, add the panel upgrade cost.
Yes. Active knob-and-tube and unremediated aluminum branch wiring are common in Ottawa's century homes and often lead insurers to surcharge or decline coverage. A full rewire commonly runs $12,000–$30,000 or more depending on size and access, and it requires an ESA notification and inspection.
