Panel and service upgrades, rewiring, circuits, fixtures, EV chargers and knob-and-tube replacement. Requires an ECRA/ESA licensed contractor in Ontario.
$120 to $180 per hour
Licensed contractor hourly rate. A 200 amp service upgrade runs in the low thousands; a full rewire is a five figure job.
Required by law. Ontario law requires this credential for the work. A contractor without it cannot legally do the job, whatever the quote says. Electricity Act, 1998, O. Reg. 570/05 (Licensing of Electrical Contractors and Master Electricians).
This work usually needs a municipal permit. Unpermitted work has to be disclosed when you sell, and an insurer can decline a claim arising from it.
You asked for the trade Electrical, and the words "caulking", and only businesses whose record lists every required credential it needs, with a check date on the record inside the last 120 days. Of the 12 businesses listed, none match every one of those.
The cost band and the licence requirements above still apply. They are what you need to judge a quote from anywhere else: whether the price is in the range, and whether the person quoting is allowed to do the work at all.
Listings here are seed data for demonstration and are labelled as such on each profile. Cost bands are what GTA homeowners are typically quoted, not offers. Always confirm a licence number against the issuing registry yourself before work starts.
