Toronto Area Housing Market: What You Need To Know About Knob & Tube

Knob and tube wiring was the electrical system that was used from the 1900 through to the 1950’s. It consists of two wires, live and neutral (no ground). Insulator knobs kept the wires isolated and ceramic tubes were used to line the holes through the wooden joists or studs.

What Makes It So Scary?

Insurance companies have deemed this style of wiring to be unsafe and a fire hazard because if it was installed poorly or has been damaged there’s a greater chance that the wires will short circuit and overheat. However, according to the Electrical Safety Authority (ESA), knob and tube wiring can be safe and functional. In fact, in many ways it’s not that inferior to modern wiring.

Unfortunately, when buying a home in Toronto, most insurance companies will not give you insurance if your new home contains knob and tube wiring.

Just make sure that you contact your insurance company to ensure that they’ll cover you before firming up on any purchase agreement.
