What to know about Wiring & rewiring

Wiring and rewiring covers the cable that runs from your electrical panel to every outlet, switch, light and appliance in the house. Some projects add circuits for a renovated kitchen, a finished basement or an addition; others replace old wiring that no longer meets today's loads or safety expectations, whether that means a few problem circuits or the whole house. In older Canadian homes, from brick Victorians to post-war bungalows and Montreal plexes, electricians still find knob-and-tube, cloth-insulated cable, ungrounded circuits and aluminum branch wiring behind the walls.

We list 14 other places within 30 km of Markham. Each pro sets their own service area, so tell us where the work is as well as what it needs.

Markham is one of 28 places we list under the name Greater Toronto Area. A pro's service area might be Markham on its own or the whole of that area — we match on the one they gave us.

No permit page published by Markham itself has been verified for this site, so what is below is what applies in Ontario. If wiring needs a permit, ask who is pulling it and whether it is in the price.

The rules we can source for this work in Ontario cover electrical work. They are set out below with the page each one came from — the regulator's words, not ours.

Wiring costs in Markham

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Type and amount of work, from a single fixture to a full rewire
  • Condition and age of the existing wiring
  • Panel and service capacity
  • Distance from the panel to the new circuit
  • Access through finished walls and ceilings
  • Permits and inspections

How to choose electricians in Markham

  • Hire a licensed electrician or electrical contractor for any wiring, panel or new circuit work.
  • Ask whether the work needs a permit and inspection, and make sure the electrician arranges it.
  • Get a written quote that lists fixtures, materials, patching of walls and ceilings, and permit costs.
  • For panel upgrades and EV chargers, ask them to check whether your electrical service can handle the added load.
  • Choose someone who explains what they found in plain language before starting.

Questions to ask electricians before you hire

  • Are you licensed for electrical work in my province?
  • Will you get the permit and arrange the inspection?
  • Can my current panel and service handle this work?
  • Will you need to open walls or ceilings, and who patches them afterwards?
  • Is the price fixed, or could it change once you see the existing wiring?
  • What warranty do you offer on your work?

Wiring permits in Ontario

Some wiring work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.

Licensing in Ontario

This type of work often has to be done by a licensed or certified trade. Ask to see licences and proof of insurance before work starts.

Common wiring questions

Is LokalMatch free for homeowners?

Yes. You never pay LokalMatch to request quotes or talk to pros. Professionals pay a fee to connect with homeowners whose projects fit their business.

How many pros will contact me?

We introduce you to a small number of relevant pros — usually no more than three — so you’re not flooded with calls. If fewer pros are available in your area, we’ll tell you instead of promising quotes we can’t deliver.

Do I have to hire someone?

No. Requesting quotes doesn’t commit you to anything. Compare your options and hire only if someone is the right fit.
