GENERATOR RENTAL RATES & COSTS IN CANADA
Generators are priced by power output (kilowatts), and the range runs from small portable units for tools and lighting to large towable diesel gensets powering whole sites or events. Sizing correctly is the key to controlling cost.
Here's how generator rental rates break down in Canada and how to size a genset to your load.
Quick answer
It typically costs $55–$1,950 per day to rent a generator in Canada. Weekly rates run about 3–4× the daily rate and monthly rates about 3–4× the weekly, which lowers the effective day rate for longer projects. Delivery, an operator and insurance are usually quoted separately, and owners set the final price, confirmed when you e-sign your rental contract.

Generator rental costs in Canada scale with output. A small portable generator (up to ~10 kW) typically rents for about $80–$200 per day, a towable mid-size unit (20–100 kW) for about $150–$500 per day, and a large towable or trailer-mounted genset (150 kW and up) for $500–$1,500+ per day. Weekly and monthly rates lower the daily cost — and most temporary-power jobs run for weeks, so ask for the longer-term rate.
What determines the price. Rated output (kW/kVA) is the main driver, followed by fuel type (diesel is standard for larger units), rental length, delivery, and options like a fuel tank, distribution panel, cables and automatic transfer switch.
Size it right. Undersizing a generator risks nuisance trips and damaged equipment; oversizing wastes fuel and money. Add up the running watts of everything you'll power, allow extra headroom for motor-startup surges (compressors, pumps, HVAC), and match a genset comfortably above that total. When in doubt, ask the owner to help size it.
Costs beyond the base rate. Plan for fuel (the biggest variable on long runs), delivery and pickup, cabling and distribution gear, and an optional damage waiver or insurance. For events and standby power, factor in refuelling logistics.
How to keep the cost down. Rent monthly for extended jobs, size the unit to your real load rather than the peak 'just in case,' and keep it fuelled efficiently. On HeavyRentals you compare live rates from local owners before you book.

FREQUENTLY ASKED QUESTIONS
In Canada, a small portable generator typically rents for about $80–$200 per day, a mid-size towable unit $150–$500 per day, and a large genset $500–$1,500+ per day. Weekly and monthly rates cost far less per day.
Add up the running watts of everything you need to power, add headroom for motor start-up surges (pumps, compressors, HVAC), and choose a genset comfortably above that total. Undersizing causes trips and damage; oversizing wastes fuel.
Usually not — fuel is typically your cost and is often the largest variable on long runs. Some rentals come with a fuel tank; confirm the fuel policy and whether refuelling is included before you book.
Yes. A monthly rate is roughly 10–12× the daily rate rather than 30 separate days, so for temporary power that runs for weeks a monthly rental is much cheaper per day.
The base rate covers the generator. Fuel, delivery, cabling, distribution panels, transfer switches and any damage waiver or insurance are billed separately.
