Understanding Aluminum Wiring Hazards in Durham Homes

Aluminum wiring itself is permitted under the OESC and can be safe when properly installed and maintained. However, in homes from the 1960s–1970s (common in older parts of Oshawa, Whitby, Ajax, and Pickering), aluminum connections can oxidize, loosen due to thermal expansion/contraction, or overheat—creating increased resistance and potential fire risks at outlets, switches, and junctions.

Key concerns:

  • Oxidation and corrosion at connections
  • Loose terminations from repeated heating/cooling cycles
  • Incompatible devices (using copper-only rated switches/receptacles)
  • Insurance challenges — Many Ontario insurers require ESA inspection, repairs, or mitigation before providing/renewing coverage; some may demand full rewiring

The Electrical Safety Authority (ESA) recommends professional assessment and repairs by a Licensed Electrical Contractor. We use only approved methods to eliminate these hazards without major disruption.

Common Signs of Aluminum Wiring Issues in Durham Homes

  • Warm or discolored outlets/switches
  • Flickering lights or intermittent power
  • Breaker trips without heavy load
  • Burning smell near electrical devices
  • Insurance flagged during renewal or home purchase

Many homes in mid-century neighbourhoods across Oshawa, Whitby, Ajax, and Pickering still have active aluminum wiring—don't wait for problems!
