    Longhouse Electric

    5.0(124 Google reviews)
    Best forhomeowners who need electrical and heating work handled by the same contractor
    In businessNot listed
    WarrantyNot listed
    EmergencyNot listed

    Why we picked them

    The combination of electrical and gas licensing in one small outfit is genuinely useful in a city full of baseboard heat and undersized panels, and a 5.0 average across 124 Google reviews is hard to argue with. We would still pin down after-hours pricing and ask to see the ESA licence and TSSA credentials in writing, simply because the listing promises 24 hour availability without publishing what that costs.

    What we like

    • 5 out of 5 from 124 Google reviews as of September 30, 2026
    • Covers both licensed electrical work and gas, furnace and air conditioning service
    • Panel and service upgrades from fuse boxes and 60 amp to 200 amp, plus EV charger wiring
    • Locally owned and operating in the GTA since 2018 by its own account
    • Reviews consistently name the same technician, pointing to hands-on ownership
    • Financing available through a third party lender for larger installs

    Things to consider

    • Hours are listed as 24 hours daily, but no after-hours or emergency call-out rate is published
    • ESA licensing, TSSA gas certification and the satisfaction guarantee are company claims worth verifying directly
    • A small owner-led team may have less scheduling flexibility than a larger fleet during peak heating season

    legacy wiring replacement and EV charger installs in older Mississauga and Brampton homes

    Effective Wiring | Electrician in Mississauga, Oakville, Brampton

    5.0(114 Google reviews)
    Best forlegacy wiring replacement and EV charger installs in older Mississauga and Brampton homes
    In businessNot listed
    WarrantyNot listed
    EmergencyNot listed

    Why we picked them

    A small licensed shop with an unusually clean review record, and the published specialties line up neatly with what actually goes wrong in GTA housing: aluminum branch circuits, knob-and-tube, and panels too small for an EV. The 5.0 from 114 reviews on Google as of September 30, 2026 is the sort of number that is hard to fake at that volume. Confirm the ESA notification is inside the quote and get the after-hours rate in writing, then this is a straightforward hire.

    What we like

    • 5.0 rating from 114 Google reviews as of September 30, 2026
    • ECRA/ESA licence number 7017156 published openly on its website
    • Named specialties in aluminum and knob-and-tube wiring replacement
    • Published 24 hour availability every day for emergency call-outs
    • Covers both residential and commercial work, including transformers and maintenance

    Things to consider

    • No pricing or call-out rates published, so quotes need to be requested directly
    • A compact team can mean less scheduling flexibility for non-urgent jobs
    • The rating shown on the company's own site differs slightly from the live Google figure

    panel upgrades and EV charger installs on older Mississauga homes

    Gibson Electrical Contracting

    5.0(172 Google reviews)
    Best forpanel upgrades and EV charger installs on older Mississauga homes
    In businessNot listed
    WarrantyNot listed
    EmergencyNot listed

    Why we picked them

    A flawless 5 out of 5 across 172 Google reviews is a genuinely strong signal, and the service mix suggests a contractor comfortable with upgrade work rather than only quick fixes. The Toronto address on the website against the Mississauga listing is the one thing we would clarify on the first call, along with coverage and after-hours pricing. Worth a quote if you are weighing a panel upgrade or an EV charger.

    What we like

    • 5 out of 5 from 172 reviews on its Google Business Profile, read September 30, 2026
    • Covers both residential and commercial work, including fit-outs and maintenance
    • Panel upgrades and EV charger installation listed as core services, not sidelines
    • Hours published as 24 hours a day, seven days a week
    • Independent contractor with a direct phone line and email rather than a call centre

    Things to consider

    • The website lists Toronto as its contact location while the Google listing is a Mississauga address, so confirm your area is covered
    • No pricing, licence number or insurance details are published, so ask for the ECRA/ESA number and proof of coverage
    • Small independent teams can be slower to respond during busy periods than large dispatch outfits
    • No online booking system, so quotes start with a phone call, email or contact form

    Circuit Savvy Electric

    4.8(245 Google reviews)
    Best forpanel upgrades and EV charger installs in older Mississauga homes
    In businessNot listed
    WarrantyNot listed
    EmergencyNot listed

    Why we picked them

    A broad residential and commercial service list backed by 245 Google reviews at 4.8, which is more feedback than most electricians in the west GTA carry. The Duke of York Electric branding on its social accounts is the one loose thread, easily resolved with a question on the phone. Strongest fit for panel upgrades, aluminum wiring and EV charger work in Mississauga's older housing.

    What we like

    • 4.8 from 245 Google reviews as read on September 30, 2026, a large sample for a local contractor
    • Service list covers the specific problems of older GTA housing: aluminum wiring, fuse panels, 200 amp upgrades
    • Level 2 EV charger installation and both Generac standby and Generlink transfer switch options
    • Hours published as open 24 hours daily, with emergency power restoration listed
    • Covers Toronto, Etobicoke, Oakville, Burlington, Milton and Brampton as well as Mississauga
    • Commercial work included, including electric sign repair and installation

    Things to consider

    • Social profiles are branded Duke of York Electric, so confirm which legal entity appears on the quote and ESA notification
    • No published pricing, including after-hours callout rates, so get the estimate in writing
    • Licence and insurance are stated by the company on its own site rather than independently verified here

    panel and service upgrades, EV chargers and commercial fit-outs across Mississauga and the western GTA

    AMM Electric Inc.

    5.0(71 Google reviews)
    Best forpanel and service upgrades, EV chargers and commercial fit-outs across Mississauga and the western GTA
    In businessNot listed
    WarrantyNot listed
    EmergencyNot listed

    Why we picked them

    The service list is broader than most residential-first electricians in the GTA, stretching into fire alarm, data cabling and building automation, which suggests real commercial experience behind the homeowner-facing marketing. A perfect 5.0 across 71 Google reviews is a genuinely good record, though the 4.9 figure on the company's own site is a reminder to go to the source. We would verify the ECRA/ESA number and get the ESA inspection fee written into the quote before work starts.

    What we like

    • 5.0 rating from 71 reviews on its Google Business Profile, read September 30, 2026
    • Covers residential, commercial and industrial work rather than one segment
    • States ECRA/ESA licensed contractor status with a licence number published on its site
    • Published hours are 24 hours a day, seven days a week, with stated emergency response
    • Specialist listings including fire alarm, UPS, data cabling, building automation and site lighting design
    • Advertises free estimates and serves Brampton, Oakville, Milton and Toronto as well as Mississauga

    Things to consider

    • The site shows a 4.9 customer review figure while the Google profile shows 5.0, so check the Google listing for current numbers
    • Licence, insurance and experience claims come from the company's own website and are worth verifying with the ESA
    • Pricing is not published, including after-hours and emergency call-out rates
    • The address is a unit number, so this looks like a dispatch operation rather than a walk-in location

Hiring

How to choose an electrician in Mississauga

  1. Check the licence

    Electrical work needs a licensed contractor in every state and province. Look the licence up with the issuing authority, not on the company's website.

  2. Ask who pulls the permit

    Panel upgrades, new circuits and rewires usually need a permit and an inspection. The electrician should handle both.

  3. Get a written quote

    It should list the materials, the panel or breaker brand and whether patching walls afterwards is included.

  4. Compare two or three quotes

    On the same scope. A much lower number often leaves out the permit or the drywall repair.

  5. Ask about the warranty

    Separate the warranty on the work from the manufacturer's warranty on parts, and get both in writing.

  6. Confirm insurance

    Ask for a current certificate of insurance and, in Canada, proof of workers compensation coverage.

Questions to ask before hiring

0 of 8 asked

Red flags

  • An offer to skip the permit to save money
  • No licence number, or one that does not check out
  • Cash only, with no written quote
  • A quote that does not say what panel or parts will be used
  • Pressure to replace a panel that has not been inspected
