Editorial Review
Our Take on Big G Electric
The Hydro Quebec aggregator arrangement is the detail worth noticing here, because applying a subsidy directly to the invoice removes the part of rebate programs that homeowners most often abandon. We would press on the warranty wording, since non transferable labour coverage is less useful if a sale is on the horizon, and on after hours rates given the 24 hour listing. Strong review volume for a suburban electrical shop, and a service list that matches what West Island housing stock actually needs.
Best forEV charger and panel upgrade work in West Island homes, with Hydro Quebec rebates handled in-house
What We Like
- 4.8 from 180 reviews on its Google Business Profile, read October 2, 2026
- Publishes an RBQ licence number, named master electrician and CMEQ membership
- Acts as a stated Hydro Quebec aggregator, applying subsidies to the invoice directly
- Tesla certified installer covering home, condo garage and commercial charger work
- Five year workmanship warranty, well beyond Quebec's one year legal minimum
- Broad coverage from the West Island through Laval, Vaudreuil and the South Shore
Things to Consider
- No prices or call-out rates published, so after hours charges need confirming
- The five year warranty is non transferable and excludes materials, by the company's own description
- Licence, insurance and partnership claims come from its own website and are worth verifying
- A Pierrefonds base means longer travel for east end or South Shore jobs

Company Background
About Big G Electric
Electrification is clearly where this contractor has put its energy. The company describes itself as a Tesla certified installer and lists charger work across three distinct settings: single family homes, condo parking garages where the syndicate of co-ownership has to approve the plan first, and commercial or industrial sites that may qualify for government funding. Those are genuinely different jobs. A home install is usually a question of panel capacity and cable run. A condo garage install involves load calculations across a shared service, metering decisions, and a board meeting that can take longer than the wiring. If you live in a Pierrefonds or Dollard-des-Ormeaux condo and want a charger at your space, ask early about who owns the circuit and how the electricity gets billed back, because that is where these projects stall.
The rest of the service list reads like a full residential and light commercial shop. Panel upgrades and rewiring, outdoor and landscape lighting, spa and pool lighting, electrical heating diagnostics and repairs, surge protection, heating and cooling including Novair heat pumps, home standby generators under a Champion dealer arrangement, and a home protection plan. There is also a stated specialism in grant and tax credit programs, which in Quebec means Hydro Quebec subsidy work.
West Island housing makes certain calls predictable. A lot of Pierrefonds, Roxboro and Dollard-des-Ormeaux stock went up between the late fifties and the seventies, which means 60 and 100 amp services that were adequate for a stove and a dryer and are not adequate for a heat pump plus a Level 2 charger plus a hot tub. That is why panel upgrades keep appearing alongside EV work: the charger is the reason for the call, the service capacity is the actual job. Electrical heating is also still common across the island, so winter failures of baseboard circuits, thermostats and control wiring are a real part of the workload. Older heritage properties in Westmount, which the company names as a service area, bring a different problem again, namely knob and tube or early cloth wiring that insurers increasingly refuse to cover.
On paperwork, Quebec is stricter than most provinces, and that is worth understanding before you hire anyone. Electrical contracting here requires an RBQ licence and membership of the Corporation des maitres electriciens du Quebec. Big G Electric publishes an RBQ number, 5723-9014, names Marisa Timmler as master electrician, states CMEQ membership, and claims five million dollars in liability coverage. Those are claims from its own site rather than figures verified here, but they are all checkable, and you should check them. The RBQ register is public and takes a minute to search. Ask whether the CMEQ declaration of work will be filed for your job, since that is what triggers inspection and what a future buyer's notary may ask about.
The five year workmanship warranty is a real differentiator in a market where one year is the legal floor, with the caveats stated plainly on the company's own site: it is non transferable and it covers labour and installation, not the parts. If you are planning to sell within five years, that non transferable clause matters. Materials fall back to the manufacturer, which is normal.
Pricing transparency is advertised but no rates are published, so the conversation to have is about after hours charges. Hours are listed as 24 hours a day, every day, and the site promotes emergency service on the main phone line. Round the clock availability almost always carries a call-out premium and sometimes a minimum billable block, so ask what a 2am visit costs versus a Tuesday morning one. Financing is offered through a third party, Financeit, which suits larger projects like a service upgrade paired with a heat pump.
Who it suits: homeowners in the western suburbs wanting electrification work done with the rebate handled for them, and commercial clients needing charger infrastructure. Who might look elsewhere: anyone wanting a two hour handyman-style fix at the lowest possible price, or a downtown plateau address far from the Pierrefonds base. The Google Business Profile rating of 4.8 from 180 reviews, read on October 2, 2026, is a solid volume for an electrical contractor of this size. Compared with the small owner-operator outfits across the island, Big G Electric is pitched as a fleet-based company with project managers, warehouse stock in Pointe-Claire and manufacturer partnerships, which tends to mean better scheduling on big jobs and less flexibility on tiny ones.

Big G Electric FAQs
What areas does Big G Electric cover around Montreal?
Its published service areas span the West Island, central Montreal, Laval and the North Shore, the off-island Vaudreuil area and the South Shore. Named municipalities include Dollard-des-Ormeaux, Kirkland, Beaconsfield, Dorval, Pierrefonds-Roxboro, Sainte-Anne-de-Bellevue, Saint-Laurent, Westmount, Outremont, TMR, Cote Saint-Luc, Lachine, LaSalle, Verdun, Chomedey, Sainte-Rose, Boisbriand, Saint-Eustache, Deux-Montagnes, Vaudreuil-Dorion, L'Ile-Perrot, Saint-Lazare, Longueuil and Brossard. The shop address is in Pierrefonds, so travel times will be shortest in the west.
Is it licensed to do electrical work in Quebec?
The company states it is fully licensed and insured, listing RBQ number 5723-9014, master electrician Marisa Timmler, and membership of the Corporation des maitres electriciens du Quebec. It also states five million dollars of liability coverage. Those are the company's own claims rather than figures confirmed here, but the RBQ register is public and the number can be searched in under a minute before you book.
Can they handle the Hydro Quebec rebate paperwork?
It says yes, and describes itself as an official Hydro Quebec aggregator. In practice that means the subsidy is applied to your project cost so you pay only the remainder, with the company claiming reimbursement from Hydro rather than you filing forms and waiting. Confirm which specific programs your job qualifies for before work starts, because eligibility depends on the equipment installed.
What does the five year warranty actually cover?
Workmanship and installation only, for five years, and it is described as non transferable. By the company's own explanation, a connection that works loose after their visit would be repaired at no charge, while the parts themselves fall back on the manufacturer's warranty. The non transferable part matters if you expect to sell the property within that window.
Do they really answer calls at night?
Hours are published as open 24 hours, seven days a week, and the site promotes emergency service on 514-941-6061. As with any electrical contractor offering round the clock response, expect an after hours premium and possibly a minimum charge, so ask what a night or weekend call-out costs compared with a scheduled weekday visit.
Will my old panel handle an EV charger?
Often not without an upgrade, especially in West Island homes built before the eighties with 60 or 100 amp service. A Level 2 charger is a substantial continuous load, and adding one alongside electric heating or a heat pump usually requires a load calculation first. Panel upgrades and rewiring are both on this contractor's service list, which is why charger quotes frequently come back as two line items rather than one.
Can they install a charger in a condo parking garage?
Yes, and the company notes that condo installations go ahead after approval by the syndicate of co-ownership. Those projects involve the building's shared electrical service, so expect questions about available capacity, sub-metering and how the power gets billed back to you. Starting the board conversation early tends to save more time than anything that happens on the technical side.
