East York · Rewiring & Old Wiring
Rewiring East York — the oldest housing stock in the city, from Leaside's 1930s detached homes to Old East York's pre-war bungalows.
East York has the oldest housing of anywhere we work: 78.8% predates 1981 and 48.8% predates 1961. That makes rewiring one of the most common jobs we do here, and it makes the assessment matter — on stock this age the branch wiring is rarely the only thing needing attention.
Built fast and built well, but on circuit counts that suited 1938 rather than a modern household.
Smaller homes, smaller services, and frequently a fuse panel worked around rather than replaced.
On housing this old the mast, weatherhead and meter base usually need replacing alongside the panel.
Charger, heat pump, basement suite — the service gets sized once for everything you are planning.
East York was built in distinct waves and each rewires differently.
Leaside went from 68 houses in 1929 to 328 built in 1938 alone. The result is an unusually consistent stock of solid detached homes — and an unusually consistent set of original circuit counts now well past what a modern household asks of them.
Just under half of East York predates 1961. Smaller homes on tighter lots, often with a fuse panel and original two-wire circuits that have been extended repeatedly rather than replaced.
East York sits downstream of infrastructure that has had its own failures — an upstream transformer station fault in August 2026 affected roughly 31,000 customers including parts of East York and Thorncliffe. Your wiring is not the grid, but sound bonding and a properly built service entrance are what protect the house when the grid misbehaves.
On stock this old the panel label and the real service size frequently disagree, and abandoned circuits sit alongside live ones. We trace it properly.
Mast, meter base, grounding and panel, so the new circuits have somewhere sound to land.

We work right across East York. If your street is not listed it almost certainly still counts — see home rewiring in full, or our East York electricians page.
It depends what is behind the walls, not on the address. Leaside's 1930s homes were well built, and many have been partially rewired over the decades. What we typically find is a mix: modern circuits in the kitchen and bathrooms, original runs feeding upstairs lighting. That often makes targeted remediation the right answer rather than a full rewire.
Not electrically. Plenty of East York homes have decommissioned knob-and-tube still stapled in place, because removing it is labour with no safety benefit. What matters is what is actually energised, and establishing that takes a meter and a licensed electrician rather than a visual guess.
Not necessarily, but it will come up. A home inspection will flag knob-and-tube, and the buyer's insurance options may narrow — which typically surfaces during the conditional period rather than at listing. Knowing what is actually live, and having it documented, puts you in a much stronger position.
On East York's oldest housing, usually. A service entrance built in the 1930s was sized for a very different household, and a rewire creates far more circuits than it was meant to carry. We assess the mast, weatherhead and meter base as part of the quote.
Thorncliffe is almost entirely high-rise, and the electrical infrastructure in an apartment building belongs to the corporation rather than an individual unit. Work there runs through the building. We will say so up front rather than book a visit that cannot proceed.
