The Middlesex-London Health Unit (MLHU) has announced an extension to its cold weather alert, with the advisory now remaining in effect through Tuesday, January 20, 2026. The decision comes as a persistent Arctic air mass continues to deliver dangerously low temperatures and wind chills to the London region.
Health Unit Urges Continued Vigilance
Originally issued earlier in the week, the alert was prolonged due to forecasts indicating that the severe cold is not relenting. The health unit emphasizes that these conditions pose significant health risks, including frostbite and hypothermia, particularly for vulnerable populations such as seniors, young children, people experiencing homelessness, and those with pre-existing health conditions.
Residents are strongly advised to limit their time outdoors, dress in multiple layers covering all exposed skin, and be aware of the early warning signs of cold-related illness. The MLHU also reminds the public to check on neighbours, friends, and family members who may be at increased risk during this prolonged cold snap.
Broader Context of a National Deep Freeze
The situation in London is not isolated. The extended alert coincides with extreme weather events across Canada, underscoring a widespread pattern of severe winter conditions. Notably, a powerful Nor'easter has forced the closure of all schools in Nova Scotia and left more than 100,000 customers without power. Meanwhile, parts of Manitoba are experiencing wind chill values plunging to a staggering -40 degrees Celsius.
Other regions are also grappling with the impacts. In Ontario, school bus cancellations and facility closures have been reported across Wellington and Dufferin counties. The province has also seen serious incidents linked to the weather, including a multi-vehicle crash on Highway 1 in Abbotsford that left a motorcyclist seriously injured, and numerous travellers stranded by highway crashes near Oakville, where the community opened its doors to nearly 100 people.
Staying Safe and Informed
As the cold alert persists into Tuesday, the key message from health and municipal officials is one of caution and community care. Residents should continue to monitor official forecasts from Environment and Climate Change Canada for updates on temperature and wind chill warnings.
The MLHU recommends that everyone prepare their homes and vehicles for the cold, ensure heating systems are working properly, and have emergency kits ready. By taking these proactive steps and looking out for one another, the community can better weather this challenging period of extreme cold.
