What electrical safety precautions should I take before and during a Toronto ice storm?

Ice storms are Toronto's most serious electrical threat, and proper preparation can prevent power outages, equipment damage, and safety hazards during these devastating weather events. The 2013 ice storm left over 300,000 Toronto Hydro customers without power for up to 10 days, demonstrating how vulnerable our electrical infrastructure is to ice accumulation and falling trees.

Before the Storm: Essential Electrical Preparations

Start your ice storm preparation by inspecting your service entrance equipment — the overhead cables, weatherhead, and mast connecting your home to Toronto Hydro's system. Ice loading can snap service entrance cables or pull the weatherhead away from your home, cutting power and creating dangerous live wire conditions. Look for loose connections, damaged weatherhead covers, or service masts that appear to be pulling away from the house. If you notice any issues, contact a licensed electrician immediately — this work requires Toronto Hydro coordination and cannot wait until after the storm.

Check your electrical panel and main breaker to ensure they're functioning properly. Test your main breaker by switching it off and back on — if it feels loose, sparks, or won't reset firmly, have an electrician inspect it before the storm. During ice storms, power fluctuations and surges are common as tree branches contact power lines, and a faulty main breaker won't protect your home's electrical system. Ensure all circuit breakers are properly labeled so you can quickly shut off power to specific areas if needed.

Generator Safety and Backup Power

If you have a portable generator, never run it inside your home, garage, or any enclosed space — carbon monoxide from generators kills more people during power outages than any other cause. Set up your generator at least 10 feet from your home with the exhaust pointing away from windows and doors. Use a manual transfer switch installed by a licensed electrician to safely connect your generator to your home's electrical system. Never plug a generator directly into a wall outlet ("backfeeding") as this can electrocute Toronto Hydro workers trying to restore power.

For whole-home standby generators, have your electrician perform pre-storm maintenance including checking the automatic transfer switch, testing the weekly exercise cycle, and ensuring the natural gas connection is secure. Ice storms often trigger multi-day power outages where a properly installed standby generator becomes essential for heating, lighting, and preserving food.

During the Storm: Critical Safety Protocols

Never touch downed power lines or anything they're touching — ice-covered trees and branches that contact power lines become energized and deadly. Stay at least 10 meters (33 feet) away from any downed lines and call 911 immediately. Even if a line appears dead, it may be re-energized automatically as Toronto Hydro's system tries to restore power.

Avoid using space heaters on overloaded circuits during power restoration. When power returns after an outage, many GTA homes experience breaker trips because residents have plugged in multiple space heaters to warm up quickly. A typical 1,500-watt space heater draws 12.5 amps — running two on the same 15-amp circuit will trip the breaker. Spread heating loads across different circuits and avoid using extension cords with space heaters.

Monitor your electrical panel for signs of problems when power is restored. If you notice flickering lights, buzzing sounds from the panel, or breakers that won't stay reset, shut off the main breaker and contact an electrician. Ice storms can cause power surges that damage panel components, and continuing to use a compromised electrical system creates fire risks.

Post-Storm Electrical Assessment

After the storm passes, inspect your service entrance equipment again for ice damage. Look for stretched or damaged service entrance cables, loose weatherhead connections, or meter base damage. Ice loading can cause micro-fractures in electrical connections that fail weeks later, so have an electrician inspect your service entrance if you experienced significant ice accumulation.

Check outdoor electrical equipment including GFCI outlets, exterior light fixtures, and any outdoor panels or disconnect switches. Ice and moisture infiltration can cause these components to fail or become unsafe. Test all GFCI outlets by pressing the test and reset buttons — if they don't function properly, have them replaced by an electrician.

Essential Emergency Supplies

Keep battery-powered or hand-crank flashlights rather than candles, which cause house fires during power outages. Have a battery-powered radio to monitor emergency broadcasts and Toronto Hydro restoration updates. Stock extra batteries for flashlights, radios, and any battery-powered devices you'll rely on during extended outages.

When to Call Professionals

Contact a licensed electrician immediately if you notice sparking, burning smells, warm outlets or switches, or any visible damage to your electrical system. For downed power lines or utility equipment damage, call Toronto Hydro at 416-542-8000 and 911 if there's immediate danger. Remember that electrical emergencies during ice storms often have extended response times due to widespread damage and dangerous working conditions.

Ice storm electrical preparation isn't just about convenience — it's about keeping your family safe when Toronto's electrical grid faces its greatest annual challenge. Proper preparation, safe generator use, and knowing when to call professionals can prevent the electrical hazards that make ice storms deadly.
