A home inspector is a generalist. They look at the roof, the furnace, the plumbing and the wiring in one visit, and they flag what they can see from the surface. That is useful, but on an older Toronto home the electrical issues that actually cost money tend to sit behind the walls and inside the panel. This is what a licensed electrician looks for when you are buying or about to renovate.

The wiring itself

Two things top the list in homes built before the mid-1970s:

  • Knob-and-tube wiring in pre-1950 houses. Insurers care about it, and active knob-and-tube feeding living space should be on a plan to replace.
  • Aluminum branch wiring in homes wired roughly between 1965 and 1975. The wire is fine, the connections are the risk.

Either one can change your insurance and your renovation budget, so it is far better to know before you close than after.

The panel and service

We open the panel and look at what the surface never shows:

  • A 60 or 100 amp service that is already full, which matters the moment you want an EV charger, a heat pump or a basement suite.
  • Federal Pioneer Stab-Lok panels, a brand with a known history of breakers that do not always trip. Many are still in service around Toronto.
  • Double-tapped breakers, two wires jammed under a lug that is rated for one. A common sign of DIY additions over the years.

The DIY history

Older homes accumulate weekend wiring. We look for ungrounded two-prong outlets, buried junction boxes with no cover, unpermitted basement and garage circuits, and additions that were never inspected. None of it is visible from the middle of the room, and all of it becomes your problem the day you own the house.

Why it is worth doing before you buy

An electrical assessment gives you two things a standard home inspection usually cannot: a realistic number for what the wiring will cost to bring up to standard, and leverage in the negotiation. If a service upgrade and a rewire are coming, that is real money you can factor into your offer.

It also sets up your renovation. If you are gutting a kitchen or finishing a basement anyway, knowing the state of the wiring first means you can permit and rewire while the walls are open, which is always the cheapest time to do it.
