Over 2,000 homes and businesses in northwest London, Ontario, have power restored after a heat wave and supply failure caused hours-long outage.
Heat Wave Triggers Electrical Failures
Northwest London, Ontario, endured hours without power on Sunday after extreme heat, with humidex readings near 40 °C, caused equipment to fail. The weather-related strain on the electrical grid coincided with a supply issue from Hydro One, compounding the outage’s impact.
Multiple Neighbourhoods Affected
More than 2,000 London Hydro customers in Masonville, Medway, Sunningdale, and surrounding areas were left without electricity. Businesses, including the Costco on Wonderland Road, relied on backup generators to maintain essential operations during the blackout.
Timeline of the Outage
The disruption began early Sunday afternoon and persisted for several hours. London Hydro reported that service was fully restored to most areas by shortly after 5 p.m., with intermittent earlier outages affecting as many as 6,000 customers in White Hills and Orchard Park.
Cause Behind the Blackout
London Hydro confirmed that a Hydro One delivery point failure was the main source of the outage, while the weekend’s extreme heat also caused equipment malfunctions. Hydro One crews worked on-site to address the issue while London Hydro rerouted power where possible.
Ongoing Heat Concerns
The outage came during the city’s fifth heat alert of the summer, issued Friday by Environment Canada and extended by the Middlesex-London Health Unit. Officials have warned residents to stay hydrated, seek cooler environments, and limit outdoor activity during peak temperatures.
Restoration Efforts and Future Preparedness
London Hydro continues to coordinate with Hydro One to monitor supply points and grid performance. Officials advise residents to check the utility’s outage map for real-time updates and to prepare for potential future weather-related service interruptions.
