A widespread outage in and around Côte-St-Luc cut electricity to roughly 15,000 addresses as temperatures plunged, raising urgent questions about heat, safety, and how long repairs could take.
Montreal’s deep freeze turned sharply more serious when a major power outage knocked out electricity for around 15,000 homes and buildings in the Côte-St-Luc area, with parts of NDG and Montreal West also reporting disruptions. The timing could hardly have been worse: the loss of power arrived during a punishing Arctic cold snap, when a working heater is not just a comfort but a safety line.
For many households, the immediate concern was heat. In winter, a few hours without electricity can cool an apartment quickly, particularly in older buildings or homes with electric heating. Even where residents still had some warmth left in walls and floors, the drop in temperature outdoors meant every minute without power felt longer, and every decision became more urgent: stay put, seek a warmer place, or find a charging point for phones and medical devices.
Reports indicated the outage began shortly after mid-morning and was linked to an equipment failure at a substation serving the area. By Saturday evening, thousands were still without electricity, and local authorities moved to open a warming option overnight with support from the Canadian Red Cross.
Quick help if your home is cold
If you’re without power, focus on warmth first: layer clothing, close doors to unused rooms, and keep one “warm room” where possible. Avoid using indoor charcoal or propane heaters that are not rated for indoor use.
If you feel unwell, dizzy, unusually tired, or confused, seek help immediately. In extreme cold, hypothermia can start subtly.
Power failures during a cold snap tend to create a cascade of problems. As indoor temperatures drop, families may try to relocate to friends, relatives, or community spaces. Roads and pavements can be icy, and the stress of travelling in freezing conditions adds risk for older residents, young children, and anyone with health conditions. In apartment buildings, loss of power can also affect elevators, hallway lighting, and access systems, leaving residents stuck or isolated.
On top of the outage itself, the wider weather pattern across Quebec was already setting a harsh backdrop: forecast guidance and reports warned of dangerously low wind chills in the region, with conditions cold enough to cause frostbite on exposed skin in a short time.
So why does a cold snap make an outage feel so much worse? First, demand rises. Even households with working power are drawing more electricity as heating systems run longer and harder. Second, repairs become more difficult: crews work outdoors in extreme wind chill, equipment can respond differently in severe cold, and the margin for error narrows when time matters for public safety. The result is a situation where the same technical failure that might be inconvenient in mild weather becomes a community emergency in deep winter.
If you’re affected, it can help to approach the next hours with a simple plan. Keep your phone charged when possible, check on neighbours who live alone, and conserve battery for updates. If you must leave home, dress in layers and cover hands, ears, and face before stepping outside. Keep a small bag ready with medication, ID, and a charger, just in case you need to relocate for warmth.
- Keep taps trickling slightly if your home is getting very cold, to reduce the risk of frozen pipes.
- Use flashlights instead of candles where possible, and never leave open flames unattended.
- If you have a car and it’s safe to use, avoid running it in a closed garage. Carbon monoxide can build up fast.
In the longer view, outages like this tend to reopen a familiar debate in winter cities: what “resilience” really looks like when cold becomes dangerous. It’s not only about restoring power quickly, but also about ensuring communities have reliable warming options, clear communications, and practical guidance for residents who may not have anywhere else to go. In a city where winter is a fact of life, the difference between inconvenience and crisis can come down to preparedness, coordination, and how quickly help reaches the people most at risk.
