The outage was primarily caused by a supply issue at one of Hydro One's delivery points into London, which led to equipment malfunction due to the extreme heat [1]. The heat wave, characterized by daytime highs that felt stifling with a humidex value of 40, was the fifth heat warning issued for the city this summer by Environment Canada [1].
The power outage also impacted several businesses, including the Costco on Wonderland Road, which used its backup generators for lighting. The outage map from London Hydro indicated that parts of Medway, Masonville, Stoney Creek, and west London remained without power, but officials expected it to be restored by 5 p.m. [1].
The extended heat alert issued by the Middlesex-London Health Unit on Friday, the fifth of the summer, exacerbated the situation, with temperatures feeling like 40°C with humidity. This alert is designed to protect vulnerable populations, such as older adults and those living alone, from heat-related illnesses [1].
The power outage also disrupted traffic lights in northwest London, creating long lines of vehicles at intersections. Despite the challenges, London Hydro officials worked diligently with Hydro One to restore power as quickly and safely as possible.
