How to Choose a Generator for Reliable Power During Ontario’s Winter Storms

Ferguson Electrical Solutions • December 9, 2025

Ontario winters are legendary for their intensity, with icy winds, heavy snowfall, and sudden storms that can leave countless homes and businesses without power. For residents of Cambridge, Waterloo, Kitchener, Guelph, Brantford and surrounding Ontario communities, a reliable generator isn’t just a luxury—it's an essential tool for safety, comfort, and peace of mind.


But with so many generator options available, how do you choose the right model to weather the next winter storm? At Ferguson Electrical Solutions, we help families and businesses make the best investment for their needs. Here’s what local homeowners and business owners should consider when selecting a generator in time for the harshest months of the year.


Why Do I Need a Generator in Ontario’s Winter?


Ontario’s winter storms can cause power outages that may last for hours—or even days. Losing power in the dead of winter can lead to:


- Heat loss (a dangerous situation in sub-zero temperatures)

- Frozen pipes and water damage

- Food spoilage

- Interrupted business operations

- Inability to charge essential devices or medical equipment


A backup generator ensures you keep the lights on, your family warm, your sump pump running, and your business protected, no matter how severe the weather.


What Size Generator Do I Need for My Ontario Home?


One of the most common questions we hear is: “What size generator do I need for my house during a power outage?” The answer depends on your unique needs, home size, and key appliances. Here’s a simplified guide:


- Essential Circuits Only: A portable generator (5,000–7,500 watts) typically powers essentials like your furnace, fridge, sump pump, and a few lights.

- Whole Home Option: A standby generator (often 14,000–22,000 watts) can seamlessly power your entire home, including electric ranges, multiple HVAC systems, and the whole lighting circuit.

- Business Needs: Industrial-grade generators may be necessary for commercial buildings, warehouses, or manufacturing plants—ask our Cambridge team for a custom assessment.


Fuel Types: Diesel, Natural Gas, or Propane?


Choosing the right fuel source is crucial for efficiency and reliability, especially during prolonged outages. In Ontario, the most common types are:


- Diesel: Known for durability and fuel efficiency; suitable for extended use but needs regular maintenance.

- Natural Gas: Clean-burning, continuous fuel supply if you’re connected to municipal lines; lower emissions.

- Propane: Long shelf life and reliable even if natural gas isn’t available; stores well on your property.


Local tip: Natural gas generators are popular in Cambridge and the Kitchener-Waterloo region due to access to utility lines and low operating costs.


Key Features to Look For


When selecting your winter-ready generator, consider these must-have features:


- Automatic Transfer Switch: Seamlessly switches power supply during an outage, so you never have to step outside in bad weather.

- Weatherproof Housing: Protects against snow and ice for long-lasting performance.

- Remote Monitoring: Allows you to check your generator’s status from your phone—a great option for cottage owners or anyone often away from home.

- Routine Maintenance Alerts: Advanced models notify you when it's time for service, ensuring reliability when you need it most.


Installation and Code Compliance in Ontario


Generator installation is not a DIY job, especially for whole-home or commercial solutions. Ontario’s electrical codes require professional installation to ensure safety, GFCI protection, and proper load management.
