Standby vs Portable Generator in Toronto: Cost and Coverage (2026)
Last updated:ByStandby Power Desk
A portable is the cheaper way to keep the lights on: $900 to $2,300 buys a manual transfer switch, an inlet box, a cord and the permit, per Kolji Bros. Electrical and Draper Electric. A 14-18 kW standby costs $9,500 to $13,000 installed, per RenoHouse, but it starts itself and covers the whole house.
Beyond the price gap, Home Generator Index's own dataset lists 56 standby generator installers across the Greater Toronto Area at an average Google rating of 4.74★ over 3,605 reviews (August 2026), so you can move straight from this verdict to a ranked shortlist of pros who do the work.
Home Generator Index reconciles conflicting contractor quotes by widening the range rather than picking a favourite, and reviews every figure before publishing.
Standby generator against Portable generator, line by line
Home Generator Index built this side-by-side from researched GTA pricing data, with every figure traceable to a named Canadian source in the cell that cites it.
| Criterion | Standby generator | Portable generator |
|---|---|---|
| Upfront cost | $6,500–$9,500 at 7.5–11 kW, $9,500–$13,000 at 14–18 kW, $13,000–$16,500 at 20–26 kW, fully installed (RenoHouse) | $900–$2,300 in hookup hardware: manual switch $800–$1,500, inlet box $20–$100, cord $30–$350, permit $50–$350 (Kolji Bros. Electrical; Draper Electric). The generator itself is a separate purchase, and no Ontario source in this dataset publishes a price for one. |
| Starting | Starts and transfers on its own when the utility drops, with nobody home | Someone has to be home to wheel it out, fuel it, start it and switch over |
| Fuel | Natural gas from the utility main. The run from the meter is $1,200–$2,200 at 30–50 ft (RenoHouse) | Gasoline carried and stored in cans, then refilled during the outage |
| Connection to the house | Service-rated 200A automatic transfer switch with load management, $1,400–$1,800 installed (RenoHouse) | Manual transfer switch, or an inlet box and cord. Ontario prohibits connecting to a wall outlet or panel without an approved transfer device (ESA) |
| Coverage | The whole panel, furnace and sump pump included | Only the circuits the switch feeds, or whatever the cords reach |
| Permits and inspection | ESA electrical permit always, plus a TSSA fuel-gas permit on gas or propane. Permits, inspections and commissioning $400–$700 on a 16 kW example (RenoHouse) | ESA permit for the transfer switch itself, $50–$350, pulled by a licensed contractor (Draper Electric) |
| Siting and noise | Outdoor cabinet on a poured pad, $400–$700 for a 4 ft by 5 ft slab, sited away from the house (RenoHouse) | Stored indoors, run outdoors and clear of doors and windows every time it is used |
| Maintenance | Annual service listed at $350 on a 7–22 kW air-cooled unit, $450 on 22–100 kW liquid-cooled (A1 Generator Monitoring) | Owner-run: oil changes, fuel handling and periodic test starts |
| Permanence | Wired and gas-piped into the house, so it stays with the property | Portable by definition, and it leaves with the owner |
Pick a standby generator when
A standby earns its price when nobody can be relied on to start a machine, and when the load is bigger than a few circuits.
- The house is empty during the day, or the outage starts at 3am. A standby on an automatic transfer switch changes over without anyone touching it.
- A sump pump has to keep running. A basement takes on water on the utility's schedule, not yours.
- The load is the whole panel. RenoHouse prices a 200A service-rated switch with load management at $1,400–$1,800 installed, which is what carries a full house.
- The property is on natural gas. The gas run from the meter is $1,200–$2,200 at 30–50 ft (RenoHouse), and after that the fuel supply never needs refilling.
- Budget for the extras up front: a 100A to 200A panel upgrade is $1,400–$1,800 as a standalone item (Kolji Bros. Electrical) and is a common surprise on older Toronto homes.
Pick a portable generator when
A portable is the right call when outages are rare, someone is usually home, and the list of things that must stay on is short.
- Outages are occasional. $900–$2,300 in hookup hardware is a tenth of a standby installation (Kolji Bros. Electrical; Draper Electric).
- Someone is home to run it. A portable does nothing until a person fuels it and starts it.
- The critical list is short: a fridge, a furnace fan, a few lights. A manual transfer switch at $800–$1,500 supplied and installed feeds a chosen set of circuits (Kolji Bros. Electrical).
- The unit needs to travel. The same generator runs a cottage, a trailer or a job site.
- Connect it properly. An inlet box is $20–$100 and a cord $30–$350 (Draper Electric), and Draper advises buying the switch, cord and inlet box together so they match.
What does each cost on a real project?
RenoHouse breaks a 16 kW Toronto installation into parts. Here is that build-up against what it costs to connect a portable legally, using Kolji Bros. Electrical and Draper Electric for the portable side:
- Standby: 16 kW generator cabinet
- $5,200–$5,800
- Standby: 200A automatic transfer switch, installed
- $1,400–$1,800
- Standby: gas line from the meter, 30–50 ft
- $1,200–$2,200
- Standby: electrical tie-in, ESA master electrician
- $1,800–$2,400
- Standby: concrete pad, permits and commissioning
- $800–$1,400
- Standby total, 14–18 kW fully installed
- $9,500–$13,000
- Portable: manual switch, inlet box, cord and permit
- $900–$2,300
Connecting a portable safely costs roughly a tenth of a standby installation, and that is the whole case for it. The generator itself is on top, and no Ontario source in this dataset publishes a purchase price for one. What the gap buys is automation. A standby transfers on its own on a January night with the house empty. A portable does nothing until someone goes outside and starts it. Every figure above excludes 13 percent HST.
Frequently asked questions
Is a standby generator worth it over a portable in Toronto?
- It depends on who is home. Hookup hardware for a portable runs $900 to $2,300 against $9,500 to $13,000 for a fully installed 14-18 kW standby (Kolji Bros. Electrical; Draper Electric; RenoHouse). The standby buys automatic changeover, whole-panel coverage and an unlimited natural gas supply. If outages are rare and someone is usually home, the portable does the job for a fraction of the money.
Can I plug a portable generator into an outlet in my house?
- No. The Electrical Safety Authority prohibits plugging a portable generator into a wall outlet or into the panel without an approved transfer device. Doing it backfeeds power onto the utility line and creates a fire and electrocution risk. A manual transfer switch at $800 to $1,500 supplied and installed is the legal minimum, and a licensed contractor must pull the ESA permit at $50 to $350.
What does a standby generator installation include?
- RenoHouse's Toronto 16 kW example breaks down as the generator cabinet at $5,200 to $5,800, a 200A service-rated automatic transfer switch at $1,400 to $1,800, a 30-50 ft gas line at $1,200 to $2,200, the ESA master electrician tie-in at $1,800 to $2,400, a poured concrete pad at $400 to $700, and permits, inspections and commissioning at $400 to $700.
Does a portable generator need a permit in Ontario?
- The generator itself does not, but connecting it to the house does. Transfer switch work needs an ESA permit at $50 to $350, pulled by a licensed electrical contractor (Draper Electric). Renting a portable or towable unit for temporary power generally needs no ESA permit at all, provided it is not tied into the building's permanent wiring.
Questions to ask your contractor
- What is your ECRA/ESA licence number, so I can check it on esasafe.com?
- How did you size the unit, and can I see the load calculation?
- Who runs the gas line, and are they a TSSA certified gas fitter?
- Does the price include the permit, the inspection and the pad? See what the line items cost
- What does your labour warranty cover, and what is the manufacturer's warranty on the unit?
