Costco generator in Canada (2026): every model, prices, and running one safely

A Costco generator in Canada is usually a Champion portable at $999.99, or $799.99 when its $200 saving comes back, which it did four times in 2026. Costco also carries Firman and A-iPower inverters, a Honeywell home standby unit and EcoFlow battery power stations from $249.99. Below is every model the Costco West and Costco East fan blogs photographed in Canadian warehouses from October 2024 to October 2026, when they went on sale, and how to run one without putting anyone at risk.

Which generators does Costco Canada sell?

From fan blog photos of Canadian warehouses, West and East, with prices as posted:

We found no Honda, Generac, Westinghouse or Yamaha generators in Canadian warehouse posts over these two years. Costco's Champion listings don't name a model number, so check the box for running watts and for a carbon monoxide shutoff, which Champion calls CO Shield on the models that have it.

Which power stations does Costco sell?

From EcoFlow Canada: the Delta 3 stores 1,024 Wh and puts out 1,800 W, switches over in under 10 milliseconds if you use it as backup for a computer or modem, and charges from empty in about 56 minutes (EcoFlow). The River 3 Plus stores 286 Wh and puts out 600 W (EcoFlow).

When do Costco generators go on sale?

• Mid-September to October: the fall storm-prep push, with $200 off the big Champion.
• November and December: holiday savings on EcoFlow power stations and the Champion.
• Late January to February: new models arrive at regular prices.
• Late February to mid-April: the spring sale, $200 off the Champions and $700 off the Honeywell standby in 2025.
• May to July: inverter and power station savings for camping and summer storms.
• Late July to October: clearance at prices ending in .97.

Generator or power station: which do you need?

• A short outage, an apartment or a quiet campsite: a power station. It makes no exhaust, so it's the only kind you can run inside; the Delta 3 can keep a fridge, modem and lights going for a while, depending on what they draw.
• A long outage, a sump pump or a furnace fan: a gas or dual fuel generator, like the Champion. Dual fuel lets you run it on a propane tank, which stores longer than gasoline.
• The whole house, automatically: a standby unit like the Honeywell, installed by licensed trades.

Add up the watts of what you need to run at once, and check the generator's running watts, not just the bigger starting figure on the box.

How do you run a generator safely?

Health Canada says to never run a generator indoors, or in a garage or shed, to run it at least 6 metres (20 feet) from buildings, and to point the exhaust away from open windows and doors. A generator that shuts off on its own when carbon monoxide builds up doesn't replace carbon monoxide alarms in your home (Health Canada).

Don't plug a generator into your home's wiring yourself. Ontario's Electrical Safety Authority says a generator should be connected by a licensed electrical contractor, and a permanent connection needs an ESA permit (ESA); Hydro-Québec says a permanent system needs a compliant transfer switch installed by a master electrician, because feeding power back into the lines can put utility crews at risk (Hydro-Québec).

How do you get a generator home and set up?

A portable generator comes in a heavy box, and a gas model needs oil before the first start, as its manual explains. An independent local helper can pick it up from the warehouse and bring it home (Costco pickup and delivery). For the connection to your house, or a standby unit, see generator installation and service: delivery and setup are general work, but the transfer switch needs a licensed electrician, and a natural gas line a licensed gas technician.

Can you return a generator to Costco?

Generators and power stations aren't named on Costco's 90-day list, which covers TVs, major appliances, computers and the other electronics Costco lists, so the general satisfaction guarantee should apply. If you're unsure about a particular model, ask at the membership counter before the 90 days pass; the rules are in the Costco return policy.
