Residential Generator Installation

Protect your Ontario home with a whole-home Generac standby generator, professionally installed by ESA-certified technicians.

Power outages across Ontario are becoming more frequent and more severe. Ice storms, heavy winds, and aging infrastructure can leave your family without heat, refrigeration, and essential home systems for hours or even days. A whole-home standby generator from Ontario Generator Systems eliminates that risk entirely.

As an authorized Generac dealer, we install industry-leading standby generators that run on natural gas or propane and activate automatically within seconds of a power failure. Every installation is performed by ESA-certified electricians who follow Ontario Electrical Safety Authority standards, ensuring your system is code-compliant and built to last.

From the initial free site inspection through final commissioning, our team handles every detail — generator sizing, fuel line coordination, municipal permits, concrete pad preparation, and electrical integration. Once installed, your generator is connected to Generac's Mobile Link remote monitoring system so you can check its status from anywhere, anytime.

Frequently Asked Questions

How long does a residential generator installation take?
Most residential installations are completed in one to two days, depending on the complexity of the electrical panel and fuel line routing. Permit timelines vary by municipality but typically add one to two weeks.
What size generator do I need for my home?
Generator sizing depends on your home's square footage, electrical panel capacity, and which appliances you want to power. Our free site inspection includes a detailed load calculation to recommend the ideal size — typically between 10kW and 26kW for most Ontario homes.
Is natural gas or propane better for a home generator?
If your home has a natural gas connection, it's usually the most convenient option since the fuel supply is continuous. Propane is ideal for rural Ontario properties without natural gas access. We help you evaluate both options during the consultation.
Do I need a permit for a generator installation in Ontario?
Yes. Ontario requires electrical permits for generator installations, and many municipalities also require building permits. We handle all permit applications as part of our installation service.
How much does a whole-home generator cost?
Residential generator systems typically range from $5,000 to $15,000 installed, depending on the generator size, fuel type, and installation complexity. Contact us for a free, no-obligation quote specific to your home.
