Preparing Your Home's Electrical System for Winter

A Checklist to Prepare your Home's Electrical System Before Winter

Why Winter Electrical Preparation Matters in Toronto

As Toronto and the GTA brace for another winter season, homeowners face unique electrical challenges that come with our harsh Canadian climate. Past winters have seen "more than 50 transformer and pole fires across the GTA" caused by "a combination of salt, snow and freezing rain" that wreaked havoc on electrical systems. At BradCon Electrical, we understand how critical it is to properly prepare your home's electrical system before temperatures drop.

Unlike other seasons, winter creates specific risks to your electrical infrastructure—from increased power demands for heating to potential outages from ice storms and snow. Proper preparation not only ensures your family stays warm and comfortable but also protects your home from electrical fires and other hazards that become more common during the colder months.

Critical Winter Electrical Preparation Checklist

1. Schedule a Professional Electrical Inspection

Before winter fully sets in, having a licensed electrician perform a comprehensive inspection is your best defense against cold-weather electrical problems. With winter on the horizon, it's important to have your home's electrical panel tested to catch any potential issues before cold weather arrives, helping prevent problems during the winter when repairs might be more difficult.

At BradCon Electrical, our winter inspection includes:

• Testing circuit breakers and panel components for proper operation
• Checking for loose connections that could cause arcing
• Verifying proper grounding throughout your home
• Inspecting GFCI outlets in bathrooms, kitchens, and outdoor areas
• Evaluating surge protection systems

Many Toronto homeowners don't realize that winter places additional strain on electrical systems as heating demands increase. This makes fall the perfect time to address small issues before they become major problems during a January ice storm.

2. Protect and Prepare Outdoor Electrical Components

Toronto's winter brings a challenging mix of snow, ice, and road salt that can damage outdoor electrical components. The road salt used to melt snow and ice is actually a primary culprit in many winter electrical problems, as salt contamination on insulators can lead to hydro pole fires and subsequent power outages.

Take these steps to protect your outdoor electrical systems:

• Clear leaves, debris, and snow away from outdoor electrical boxes
• Ensure weatherproof covers are intact on all outdoor outlets
• Check that exterior lighting is securely fastened to withstand wind
• Trim tree branches that could fall on power lines during ice storms
• Waterproof all outdoor connections and junction boxes

For homeowners with pool equipment, hot tubs, or outdoor kitchens, proper winterization of these specialized electrical systems is essential to prevent costly damage.

3. Assess Your Home's Heating Systems

Your heating system is critical during Toronto winters, and most heating equipment relies heavily on your electrical system. No matter what kind of HVAC system you have, it uses electricity to run, making it important to ensure your heating system has a proper connection to the power grid.

Key heating system preparations include:

• Having your furnace or heat pump professionally serviced
• Testing thermostat operation and replacing batteries if needed
• Checking that heating vents and returns are unblocked
• Verifying that space heaters have appropriate circuits to prevent overloads
• Installing a programmable or smart thermostat to improve efficiency

If you use space heaters in certain rooms, remember that these devices draw significant power. Never use extension cords with space heaters, and ensure they're plugged directly into wall outlets on circuits that can handle their amperage requirements.

4. Prepare for Potential Power Outages

Toronto winters occasionally bring severe weather that can knock out power for hours or even days. In past years, ice storms left more than 400,000 Ontario residents without power, making generator backup systems crucial for maintaining essential services like heating, refrigeration and water during outages.

Be prepared for outages with these measures:

• Install surge protectors on sensitive electronics
• Consider a whole-home surge protection system
• Keep battery-powered emergency lighting accessible
• Develop a power outage plan that all family members understand
• Investigate backup power options like generators or battery systems

For many GTA homeowners, a backup generator provides essential peace of mind. BradCon Electrical specializes in installing manual transfer switches that allow safe connection of portable generators to your home's electrical system during outages.

5. Address Energy Efficiency Concerns

Winter brings higher energy bills, making efficiency improvements particularly valuable. Lighting can account for up to 20% of your home electricity usage, making energy-efficient lighting solutions particularly valuable during the darker winter months.

Improve your winter efficiency with these steps:

• Switch to LED lighting throughout your home
• Install timers or motion sensors on exterior lighting
• Seal electrical boxes and outlets to prevent drafts
• Check that attic ventilation fans are functioning properly
• Consider upgrading to a smart home system for better control

Many Toronto homeowners don't realize that leaky electrical outlets and switches can account for up to 10% of a home's heat loss. Simple foam gaskets installed behind cover plates can make a significant difference in your heating efficiency.

Toronto-Specific Winter Electrical Considerations

Living in the Greater Toronto Area means dealing with specific winter electrical challenges that homeowners in milder climates don't face:

Salt Contamination Protection

The brine solution used by Toronto's Transportation Services to treat roads in winter contains a 23% salt concentration, with crews using an average of 2.3 million liters every winter. This salt often becomes airborne during windy conditions, contaminating electrical equipment and contributing to pole fires and outages.

For homes near heavily-treated roads, additional protection for electrical components may be necessary, including more frequent cleaning of outdoor electrical boxes and special sealants on connections.

Ice Storm Preparation

Toronto's history of severe ice storms makes specific preparation essential. In both 2013 and 2016, Ontario was hit with significant ice storms that left hundreds of thousands of residents without power, as ice accumulation caused trees and power lines to fall.

To prepare for potential ice storms:

• Keep tree branches trimmed away from your service drop (the power line connecting to your home)
• Secure loose exterior electrical components that could be damaged by ice
• Create an emergency plan that includes alternative heating options
• Consider installing a manual transfer switch for generator connection
• Keep emergency contact information for Toronto Hydro easily accessible
