A severe storm moving through southern Ontario has knocked out power to tens of thousands of customers in Toronto and surrounding communities. Utility crews are responding to widespread outages caused by the storm, which brought damaging winds and heavy rain capable of downing trees and power lines across the region.
If you are in the affected area, you may notice flickering lights, full power loss, downed lines or tree limbs on roads, and traffic lights that are dark or flashing. Treat any dark intersection as a four-way stop, and stay well away from downed power lines — assume they are live and report them to your local utility.
What to keep in mind while crews work
Residents across Toronto and southern Ontario are affected, though restoration times will vary by neighborhood depending on the extent of the damage. Utilities typically restore critical infrastructure and the largest outage clusters first, so some customers could be waiting hours or longer in hard-hit pockets.
A few practical steps while you wait: keep refrigerator and freezer doors closed — a full freezer holds safe temperatures for roughly 48 hours if unopened. Use flashlights instead of candles to reduce fire risk, and never run a generator, grill, or camp stove indoors or in a garage because of carbon monoxide danger. If you rely on powered medical equipment, contact your utility to register as a priority customer and have a backup plan ready.
It is worth noting that this outage is weather-driven — strong winds and storm damage are the cause, not any grid or geomagnetic issue. Monitor updates from your local utility for restoration estimates specific to your address.

Frequently Asked Questions
How long until my power is restored?
Restoration times vary by neighborhood — utilities prioritize critical infrastructure and the largest outage clusters first, so most customers are typically back within hours, though hard-hit areas with downed lines may take longer. Check your local utility's outage map for an estimate for your address.
Is this outage connected to space weather or a geomagnetic storm?
No — this outage was caused by a severe storm with damaging winds moving through southern Ontario, not by any geomagnetic activity. Downed trees and power lines from the storm are the reason for the outages.
What should I do right now if I'm without power?
Keep fridge and freezer doors closed, use flashlights rather than candles, and unplug major electronics to protect them from surges when power returns. If you see a downed power line, stay far away and report it to your utility immediately.
Is it safe to use a generator during this outage?
Yes, but only outdoors and well away from windows, doors, and vents — never in a house or garage, since generators produce deadly carbon monoxide. Follow the manufacturer's instructions and never plug a generator directly into a wall outlet.
