Electrician — Thunder Bay

We chase the fault, not the clock.

Eleven licensed electricians out of Alloy Drive. Standby generators, panels, service masts and the three-in-the-morning no-power call, from the Harbour Expressway out to Kakabeka and Murillo. ESA permit pulled on every job and the certificate lands in your inbox.

01 / What we do

Electrical work, done properly

Straight answers, tidy work and no surprises — across Thunder Bay and the surrounding area.

01

Standby generators & transfer switches

Automatic standby units and manual transfer panels sized to what you actually need running — furnace, well pump, fridge, sump. Load-tested in front of you, with the changeover procedure taped inside the panel door.

From $6,900

02

No-power & storm callouts

Wind off the lake, a tree through a service mast, half the house dark. A licensed electrician answers the phone through the night, and if it's the utility's problem rather than yours we say so instead of billing you to find out.

From $195 call-out

03

Panel & service upgrades

60 and 100 amp services taken up to 200 amp, mast and meter base included when the weather has had them. We pull the ESA notification, arrange the disconnect with Synergy North, and book the inspection before we leave.

From $2,600

04

Service masts & weatherhead repairs

Ice and wind pull masts off houses here every winter. We can make it safe the same day and do the permanent repair once the utility has their conductors clear.

From $1,450

05

Whole-home surge protection

A panel-mounted surge device costs less than one furnace control board. Worth it anywhere the supply flickers, which up here is everywhere.

From $525

06

Camp & cottage wiring

Generator inlets, inverters, battery banks and proper grounding for places that sit empty half the year, out along Shuniah and toward the Sibley Peninsula.

07

Knob-and-tube & aluminum rewiring

Full and partial rewires for older Port Arthur and Fort William houses, written up the way an insurer wants to see it before they'll renew the policy.

08

Pot lights, heat trace & block heaters

LED pot lights cut into finished ceilings, roof and eaves heat trace fitted before the ice dams start, and block heater outlets that don't trip every January.

From $145 per light

09

EV charger installation

Level 2 chargers wired to code with a load calculation done first, and a cold-weather cable that still bends at forty below.

From $950

What the neighbours say

January's ice took our mast right off the wall. Erik had a crew here before lunch, made it safe, and the permanent repair and the ESA certificate were done two days after we were reconnected. He also told me exactly what the insurance adjuster would ask for, which saved me a week of phone calls.

Standby generator for the well pump and the furnace. They sized it to what we actually run instead of selling us the biggest one on the truck, and they load-tested it while we watched. Three outages since and we haven't noticed one of them.

A breaker had been tripping since spring and two other electricians shrugged at it. Thor's guy spent two hours with a meter, found a nail through a wire behind a basement shelf, and charged me for the two hours. That was the whole bill.
Jamie O.Westfort · HomeStars
Three-phase service upgrade and new lighting through the whole shop. They worked evenings so we never lost a day's production, and the panel schedule is typed and laminated on the door. First electricians who ever left us paperwork.

Solid work on a generator inlet and a panel change. They were three weeks out when I called, which is a long wait, but they said so up front instead of stringing me along, and the price on the invoice was the price on the quote.

04 / Who turns up

Named for a grandfather, not a comic book

Thorvald Thoresen wired grain elevators on the Thunder Bay waterfront for thirty-one years and nobody ever called him anything but Thor. His grandson Erik got his 309A in 1994 and put the old man's name over the door three years later. There are eleven of us now, four of them apprentices out of Confederation College, running five trucks with a generator on the back of two of them. Up here the wind comes off the lake and takes the power with it, so a good part of our work is making sure a house or a shop can carry on without the grid for a few days. The rest is ordinary: panels, pot lights, rewires, and finding the one nicked wire behind a shelf that has been tripping your breaker since March.

09 / Straight answers

Questions we get asked

Somebody licensed answers. If the whole street is dark it's Synergy North, and we'll tell you that rather than charge you to come out and find out. If it's only your house, we come.

Most Thunder Bay houses land between $6,900 and $14,000 installed, and almost all of that spread is how much of the house you want running. We price two options — essentials only, and whole house — so you can see the difference before you choose.

Any service, panel or new circuit work in Ontario needs an ESA notification. We pull it, it's inside the quoted price, and we book the inspection. Without the certificate an insurer can decline a claim.

Call us and call Synergy North. We can usually make it safe the same day; the permanent repair happens once their conductors are clear. Take photographs before anybody touches it, because your insurer will want them.

Kakabeka, Murillo, Oliver Paipoonge, Shuniah, Neebing and Nolalu are regular runs. Anything further out we group into one day, so there can be a wait for work that isn't an emergency.

Erik's grandfather Thorvald wired grain elevators on the waterfront for thirty-one years and nobody called him anything else. The name was his long before it was ours.
