Ottawa homeowners know outages here aren’t just annoying — they can be dangerous in −30 °C winters and disruptive during summer storms. From the 1998 Ice Storm to the 2018 tornadoes and the May 2022 derecho, our city has seen grid damage that left tens of thousands without electricity for days — in some pockets, nearly two weeks. This guide explains your backup power options (portable vs. standby generators) and how GenerLink makes a portable setup safer and simpler, so your home stays warm, lit, and connected when the grid goes down. If you’re planning a project, start with Ottawa Electric’s Generator Installation page for quotes and timelines.

Key Takeaways
- Ottawa has a real outage history:
- 1998: ~69.6 mm of freezing rain in five days; 1,000+ towers and 30,000+ poles down; 230,000+ Ontarians without power.
- 2018: EF-3/EF-2 tornadoes damaged the Merivale station; 171,462 service outages; full restoration in up to four days.
- 2022: Derecho was Hydro Ottawa’s most devastating storm; 400+ poles damaged; ~180,000 customers affected; some out nearly two weeks.
- Portable vs. standby: Portables are lower-cost but manual; standbys cost more up front but start automatically and can run for days on natural gas.
- GenerLink (meter-mounted transfer device) lets a portable safely feed your main panel and prevents backfeed — no extension-cord spaghetti. Use is subject to utility approval.
- Ontario rules: Permanently connected (standby) generators need a transfer device and an ESA notification/permit.
- Safety first: Operate portables outdoors and ≥ 6 m (20 ft) from doors/windows; install CO alarms.
Ottawa’s Biggest Outages (and why preparation matters)
- 1998 Ice Storm: Over Jan 4–9, Ottawa took on ~69.6 mm of freezing rain. The weight of ice toppled 1,000+ towers and 30,000+ poles, and 230,000+ people in Ontario were without power — some for weeks.
- 2018 Tornadoes: EF-3 and EF-2 tornadoes tore through the city and damaged critical infrastructure at Merivale. Hydro Ottawa reported 171,462 service outages; power was fully restored within four days.
- May 2022 Derecho: Winds up to 190 km/h snapped 400+ poles. Hydro Ottawa called it the most devastating event in its history; about ~180,000 customers (over half the city) lost power, with the last pockets waiting close to two weeks.
Portable vs. Standby Generators for Ottawa Homes
| Factor | Portable Generator | Standby (Fixed) Generator |
|---|---|---|
| Typical upfront | Many 2–7 kW units commonly ~$400–$1,500 (Canada examples). | Turnkey projects (unit + install) commonly ~$6,800–$12,000+ in Canada, depending on size/site work. |
| Operation | Manual: wheel out, start, refuel, manage loads; best with a transfer device or GenerLink to power the panel. | Automatic: senses outage, starts, and switches your home in seconds; can power essential or whole-home loads. |
| Fuel & runtime | Gas/propane; limited tank → refuel every few hours. Fuel availability can be a problem in storms. | Natural gas or large propane → multi-day runtime (natural gas effectively continuous). |
| Installation | Minimal for corded use; safer and more convenient with GenerLink or a manual transfer switch. | Professional install: pad, wiring, gas hookup, automatic transfer switch; permits/inspections required. |
| Maintenance | Run/test monthly; change oil; stabilize or rotate fuel. | Annual service; many units self-test weekly; no gasoline storage if on natural gas. |
| Ottawa weather | Must run outdoors & dry; refuelling in snow/ice is unpleasant and risky; CO hazard if misused. | Weather-rated enclosures; hands-off in blizzards/ice storms; better suited for extended outages. |

What is GenerLink — and why Ottawa homeowners like it
GenerLink is a UL-listed, meter-mounted transfer switch (UL1008M) installed behind your hydro meter. During an outage you plug your portable generator into the GenerLink receptacle; it feeds your main panel and isolates your home from the grid to prevent backfeed. That means you can power hard-wired loads (furnace, sump pump) without running extension cords.
Key benefits
- Safer: Built-in isolation prevents backfeeding and protects utility crews/equipment.
- Simpler: No sub-panel required; manage circuits from your existing breakers up to your generator’s capacity.
- Fast to use: Roll out the generator, plug in, start, and flip breakers — everything stays at the panel.
Important local note: In Ontario, use is subject to your Local Distribution Company’s (utility’s) approval and procedures. ESA’s latest Distributor Bulletin states some supply authorities do not permit meter-base plug-in transfer devices, or they may require connection authorization — your Licensed Electrical Contractor will verify acceptance and coordinate a safe meter pull.
Costs at a glance (typical ranges)
- Portable generators: commonly ~$400–$1,500 for 1–7 kW models (unit only).
- Standby systems (unit + installation): often ~$6,800–$12,000+ depending on kW, gas line work, trenching, and site specifics.
- Why ranges vary: Larger kW, longer gas runs, slab work, load-shedding modules, and upgrade needs (panel/service) can move you up the scale.

Safety essentials for portable generators
- Never run indoors or in garages/sheds.
- Place ≥ 6 m (20 ft) from all doors, windows, and vents; point exhaust away from the house.
- Install CO alarms on every floor and test them.
Conclusion
When Ottawa’s weather turns rough, a backup plan shouldn’t be guesswork.

FAQs
What size generator do I need?
For essentials (furnace blower, fridge, sump, lights, Wi-Fi) many detached homes manage with a 5–7 kW portable. For whole-home comfort (multiple circuits, A/C, well pump), homeowners often choose 13–20 kW standby systems. A load assessment will right-size the unit for you.
Can a portable run my gas furnace?
Yes — but not with an extension cord. Furnaces are hard-wired; you’ll need a transfer switch or GenerLink to feed your panel safely (and to prevent backfeed).
Do I need permits in Ottawa?
For standby (permanent) installs: Yes. In Ontario you must file an ESA notification/permit and include a transfer device to protect your home and the utility system. Your Licensed Electrical Contractor handles this.
For meter-mounted devices (e.g., GenerLink): ESA notes some supply authorities do not permit these devices or may require authorization; your contractor will confirm your utility’s position and coordinate any required meter work.
How long can I run a generator?
Portables run as long as you can safely refuel (often 5–10 hours per tank at partial load). Standbys on natural gas can run for days; on propane, runtime depends on tank size.
What about noise?
Portables vary widely (inverter models are quieter but cost more). Standby units are enclosed and often sit in the 65–70 dB range at load — placement matters, so we’ll confirm clearances and best location during the site visit.
Is GenerLink compatible with every portable?
No. Compatibility depends on plug type, wattage, voltage (120/240 V), and sometimes GFCI behaviour. Your contractor will check your model against GenerLink’s guidelines.
