Standby Generator Cost in Canada: Installed Prices & Guide

A home standby generator is the most reliable way to keep a Canadian home heated, lit and protected during an ice storm or extended power outage. It runs on natural gas or propane, starts automatically within seconds, and powers either your essential circuits or your whole home.

But the generator is only part of the price. The automatic transfer switch, gas line, concrete pad, electrical work and permits can add up to almost half of the total. This guide breaks down what a standby generator really costs installed in Canada in 2026, by size, province and component.

How Much Does a Standby Generator Cost in Canada?

A home standby generator costs $8,000 to $18,000 installed in Canada in 2026, before tax. Most homeowners pay $11,000 to $14,000 for a typical 20 to 22 kW whole-home system.

The generator unit usually accounts for 50 to 60% of the bill. The rest covers the automatic transfer switch, gas or propane piping, the pad, electrical connection, permits and labour.

Your final price depends on four things: generator capacity (kW), fuel type, distance from the gas meter and electrical panel, and local labour rates and permit fees.

Installed Standby Generator Costs by Size (kW)

Generator capacity, measured in kilowatts (kW), is the biggest single driver of standby generator cost. Each step up in size adds to the unit price and often requires a larger transfer switch, bigger gas line and higher gas meter capacity.

10–14 kW Standby Generators

A 10 to 14 kW standby generator costs about $8,000 to $11,500 installed. It is the most affordable entry point into automatic home backup.

This size powers essential circuits: furnace blower, refrigerator, sump pump, well pump, lights, internet and a few outlets. It pairs with an essential-circuit automatic transfer switch, which keeps installation simpler. Models include the Generac 10 kW and 13 kW Guardian and the Cummins QuietConnect RS13A.

18–20 kW Standby Generators

An 18 to 20 kW standby generator costs about $10,000 to $14,500 installed. It is the most popular size for whole-home backup in Canada.

A 20 kW unit can typically start and run a central air conditioner, electric range and multiple heating zones at once. The Cummins RS20A and Generac 20 kW Guardian are common choices. For homes with high-draw appliances, Smart Management Modules shed large loads automatically to avoid overload.

22–24 kW Standby Generators

A 22 to 24 kW standby generator costs about $11,000 to $16,000 installed, with $13,000 a common midpoint for a 22 kW system.

The Generac 22 kW is the largest air-cooled Guardian model. It suits large homes over 2,500 sq ft with central air, in-floor heating or large water heaters. Expect a 200 A whole-house transfer switch with load management at this size.

26 kW and Larger Standby Generators

Generators of 26 kW and above typically cost $15,000 to $35,000+ installed. These are often liquid-cooled units built for long run times and heavy loads.

This size suits large estates, all-electric homes with electric baseboard heat, farms, and small commercial properties. Installations may require a larger gas meter from your utility, 400 A service and engineered pad designs. For commercial-grade backup, the Cummins RS50 delivers 50 kW.

Installed Standby Generator Costs by Province

Standby generator installation costs vary by province because of labour rates, permit fees, fuel availability and sales tax. Ontario and British Columbia tend to sit at the higher end, while Québec and the Prairies are often slightly lower.

Ranges are typical market estimates for 2026 and vary by home. Get a written quote for your property.

Two regional patterns matter most:

• Rural and Atlantic homes often have no natural gas service, so they run on propane. Add the cost of a propane tank, either rented or bought from your supplier.

• Cold regions like northern Ontario, the Prairies and the North benefit from cold-weather packages such as battery warmers and oil heaters. Cummins extreme cold weather models operate down to -40°C.

What Is Included in a Standby Generator Installation Cost?

A complete standby generator installation includes the generator, an automatic transfer switch, electrical wiring, a fuel line, a pad, permits and labour. On a typical 22 kW system, everything except the generator adds up to about $6,000 to $7,000.

Generator Unit and Automatic Transfer Switch

The generator unit costs $3,000 to $8,000 for most residential sizes. The automatic transfer switch (ATS) adds $1,400 to $3,000 when bought separately.

The ATS is the safety heart of the system. It disconnects your home from the utility grid before the generator feeds it, which prevents dangerous backfeed onto power lines. Every Generac Guardian model includes a transfer switch, while Cummins QuietConnect units pair with RSS or RA series switches.

Electrical Wiring and Panel Connections

Electrical work typically costs $1,800 to $2,400. A licensed electrician runs the cable from the generator to the transfer switch and ties it into your main electrical panel.

Costs rise if your panel needs an upgrade, if you have older 100 A service, or if the generator sits far from the panel. A sub-panel for essential circuits also adds labour.

Natural Gas or Propane Line Installation

A gas line typically costs $1,200 to $2,200 for a 30 to 50 ft run, installed by a licensed gas fitter. Each extra foot of pipe adds cost.

Larger generators may need a bigger gas meter or regulator from your utility, such as Enbridge Gas, Énergir or FortisBC. Propane installations need a correctly sized tank, which your propane supplier usually rents or sells separately.

Generator Pad and Site Preparation

A generator pad and site prep cost $400 to $700. Most units sit on a composite or concrete pad over compacted gravel, raised above grade.

Placement must respect manufacturer clearances from windows, doors and vents, often 5 ft for Generac units. In snowy regions, keep the generator out from under roof eaves to prevent snow and ice buildup.

Permits, Inspections, and Installation Labour

Permits, inspection and commissioning typically cost $400 to $700, on top of installation labour built into each trade's price.

Two trades usually sign off: a licensed electrician for the electrical work and a licensed gas fitter for the fuel connection. The installer then commissions the generator, tests the transfer and sets the weekly exercise cycle.

What Factors Affect Standby Generator Installation Costs in Canada?

The biggest cost factors are generator size, fuel type and installation distance. Two homes buying the same 22 kW generator can receive quotes thousands of dollars apart.

• Generator capacity (kW): larger units cost more and need bigger transfer switches, gas lines and wiring.

• Brand and engine type: air-cooled engines cost less; liquid-cooled engines cost more but suit longer run times and larger loads.

• Fuel type: natural gas needs a meter connection; propane needs a tank, which adds cost if you don't already have one.

• Distance to the gas meter and panel: every extra metre of gas pipe and electrical cable adds materials and labour.

• Electrical panel condition: older 100 A panels may need an upgrade to 200 A service.

• Transfer switch type: a whole-house 200 A switch with load management costs more than an essential-circuit switch.

• Gas meter capacity: large generators may need a utility meter upgrade.

• Site conditions: slopes, rock, tight lot lines and noise bylaws can complicate placement.

• Province and city: labour rates, permit fees and sales tax differ across Canada.

• Cold-weather options: battery warmers and oil heaters add cost but improve starting in deep cold.

Natural Gas vs. Propane Standby Generators: Cost Differences

Natural gas standby generators are usually cheaper to install and run if your home already has gas service. Propane generators cost more upfront when you need a tank, but they are the only automatic option for many rural Canadian homes.

Propane also delivers slightly more power. For example, the Generac 22 kW produces 22,000 W on propane and 19,500 W on natural gas.

Essential Circuit Backup vs. Whole-Home Generator: Which Costs More?

A whole-home generator costs more, typically $3,000 to $5,000 more than an essential circuit system. The gap comes from a larger generator, a 200 A whole-house transfer switch and more complex electrical work.

Choose essential circuit backup if your budget is tight, your home is heated by gas or propane, and you only need to protect against frozen pipes, spoiled food and flooded basements.

Choose whole-home backup if you have central air, electric heating, a home office, medical equipment, or frequent multi-day outages.

How Much Does It Cost to Run and Maintain a Standby Generator?

A standby generator typically costs $200 to $500 per year to maintain, plus fuel only when it runs during an outage or weekly self-test.

Fuel costs: a 22 kW generator at half load burns about 5 to 6 m³ of natural gas or 8 to 10 L of propane per hour. Multiply by your local rate per cubic metre or per litre. Natural gas is usually the cheaper fuel per hour of runtime.

Weekly exercise cycle: most units run a short self-test every week to keep the engine lubricated and the battery charged. This uses only a small amount of fuel.

Annual maintenance typically includes:

• Oil and oil filter change

• Air filter and spark plug replacement

• Battery test and replacement every 3 to 5 years

• Transfer switch and controller inspection

• Load test to confirm full output

Regular service protects your warranty. Cummins QuietConnect units carry a 5-year or 2,000-hour limited warranty, and Generac Guardian models carry a 5-year limited warranty. Volts offers generator maintenance services with annual service and automatic transfer testing.

Do You Need Permits to Install a Standby Generator in Canada?

Yes. Every permanently connected standby generator in Canada needs electrical permits, and gas or propane connections need fuel permits. Work must follow the Canadian Electrical Code (CSA C22.1) and the CSA B149.1 natural gas and propane installation code.

• Ontario: an ESA notification of work for the electrical connection, and TSSA-regulated gas work by a registered gas contractor.

• Québec: electrical work by a CMEQ-member master electrician and gas work by an RBQ-licensed contractor.

• British Columbia: electrical and gas permits through Technical Safety BC or your municipality.

• Alberta: electrical and gas permits under the Safety Codes Act, issued by your municipality or an accredited agency.

• Other provinces: permits through the provincial electrical and fuel safety authority.

Your municipality may also have rules on setbacks, placement and noise. A qualified installer pulls the permits and books inspections as part of the quote.

Standby Generator vs. Portable Generator: Cost Comparison

A portable generator costs far less, about $1,500 to $2,800 installed with a panel interlock kit, compared with $8,000 to $18,000 for a standby generator. The trade-off is convenience, power and safety.

A portable unit suits occasional, short outages and cottages. A standby generator suits homeowners who want hands-free protection during long winter outages, especially when nobody is home. Compare portable options in our Dual Fuel Inverter Generator guide.

How to Choose the Right Standby Generator for Your Home

The right standby generator is sized to your actual electrical loads, not your home's square footage. Oversizing wastes money; undersizing causes overloads and failed starts.

1. List what must run during an outage. Furnace, sump or well pump, fridge, lights, internet, central air, water heater, medical devices.

2. Add running watts and starting watts. Motors like well pumps and AC compressors need two to three times their running power to start. A 1 hp well pump can need 4,000 to 6,000 W at start-up.

3. Pick essential or whole-home coverage. This decides the transfer switch type and generator size.

4. Match the size to your loads.

• Essential circuits: 10–14 kW

• Average Canadian home, full backup: 13–20 kW

• Large home with central air: 20 kW or more

5. Choose the fuel. Natural gas if you have service; propane for rural properties.

6. Check cold-weather ratings. Standard Cummins QuietConnect units run down to -18°C; extreme cold models run to -40°C.

7. Compare warranty, noise and monitoring. Look for a 5-year warranty, a sound level around 65 dB or lower, and app monitoring such as Generac Mobile Link or Cummins Cloud Connect.

8. Get a professional load calculation. Contact Volts for a free sizing recommendation.

Is a Whole-Home Standby Generator Worth the Investment?

A whole-home standby generator is worth it for most Canadian homeowners who face frequent or long outages. It does not pay for itself through energy savings, but it prevents costly damage and keeps life running.

It is worth it if you:

• Live in an area hit by ice storms, freezing rain or high winds

• Rely on a sump pump or well pump

• Work from home or use medical equipment

• Travel often and need automatic protection when away

• Want to avoid frozen pipes, flooded basements and spoiled food

One outage can cost more than you think. A burst pipe, flooded basement or spoiled freezer can run into thousands of dollars, often more than an insurance deductible.

It may not be worth it if outages in your area are rare and short. A portable generator or a home battery system may be a better fit. To spread the upfront cost, Volts offers financing options.

Final Thoughts

A home standby generator in Canada typically costs $8,000 to $18,000 installed, with most whole-home systems landing between $11,000 and $14,000. Your final price depends on generator size, fuel type, the distance to your gas meter and panel, your electrical service, and local permit and labour rates. The most important decision is capacity: the right size covers your critical loads without paying for power you never use.

FAQs

How much does a 22 kW standby generator cost installed in Canada?

A 22 kW standby generator typically costs $11,000 to $16,000 installed, before tax. About $13,000 is a common midpoint. The generator itself is roughly half of that; the rest covers the transfer switch, gas line, pad, wiring and permits.

What size generator do I need for a Canadian home?

Most Canadian homes need 13 to 20 kW for full backup. Essential circuits only need 10 to 14 kW, while large homes with central air need 20 kW or more. A load calculation gives the exact size.

Is a natural gas or propane generator cheaper to run?

Natural gas is usually cheaper to run and never needs refuelling while utility gas flows. Propane costs more per hour but is the best option for rural homes without gas service.

How long does a standby generator last?

A well-maintained air-cooled standby generator typically lasts 10,000 to 20,000 running hours, or about 15 to 25 years for residential use. Liquid-cooled units can last longer.

How long does standby generator installation take?

The installation itself usually takes one to three days. Permits, gas meter upgrades and inspections can extend the full timeline to a few weeks.

Can a standby generator run during a multi-day outage?

Yes. A natural gas generator can run as long as utility gas flows, and a propane unit runs as long as the tank has fuel. Most manufacturers recommend periodic shutdowns for oil checks during very long runs.

Does a standby generator increase home value?

A standby generator can add resale appeal, especially in outage-prone regions. Buyers see it as a ready-to-use safety feature, though the value added varies by market.

Are there rebates for standby generators in Canada?

There are generally no government rebates for fossil-fuel standby generators. Battery backup systems may qualify for provincial incentives, such as Québec's Rénoclimat battery rebate. Financing can help spread the cost of a generator.
