Aluminum wiring is a fire hazard wherever the wire is spliced or makes a connection with an outlet, switch, circuit breaker, or other component of your electrical system. Additionally, aluminum wire contracts and expands with temperature changes, which can result in overheating, sparking, and fires.
Homes built between the 1960’s and early 1970’s likely contain aluminum wiring because it was a cheaper alternative to copper. Statistically, homes containing aluminum wire are 55 times more likely to have a fire. Thousands of Calgary homes were wired during this time including many communities such as Bayview, Braeside, Canyon Meadows, Cedar Brae, Lake Bonavista, Palliser, Parkland, Pump Hill, Queensland, and Willow Park. Some communities in Calgary’s Surrounding area where also constructed during this time, such as in Okotoks, High River, Canmore, Cochrane, Airdrie, Black Diamond, and more.
