If you’ve opened your hydro bill lately and felt a knot in your stomach, you’re not alone. The average Ontario household now pays between $1,200 and $1,500 per year in electricity costs — and for many families, it’s climbing even higher. With Ontario’s time-of-use pricing structure, global adjustment charges, and the ongoing pressure of inflation, that number can feel completely out of your control.
But here’s the thing: it doesn’t have to be.
After years of covering frugal living strategies for Canadians, I’ve tested and researched exactly what moves the needle on a hydro bill — and what’s mostly marketing fluff. In this guide, I’m giving you 15 proven strategies that real Ontario households use to cut their electricity costs, some by 20–40% annually. We’ll cover quick wins you can implement today, smart upgrades that pay for themselves, and the often-overlooked billing tricks that your utility company doesn’t advertise.
Whether you’re renting a downtown Toronto condo or heating a farmhouse in Simcoe County, at least a dozen of these tips will apply directly to your situation. Let’s get into it.
Understanding Your Ontario Hydro Bill First
Before you can lower your hydro bill in Ontario, you need to understand what you’re actually paying for. Most people are shocked to learn that the electricity you actually use — the “energy” charge — represents only about 30–35% of your total bill. [Source: Ontario Energy Board — oeb.ca]
The rest breaks down roughly like this: delivery charges (~30%), regulatory charges (~5%), the Global Adjustment (~20%), and HST on top of everything. The Global Adjustment, in particular, is a fee that covers the cost of maintaining Ontario’s power infrastructure and contract premiums for generators — and it fluctuates monthly.
What this means practically is that even if you cut your electricity consumption in half, you’d only reduce your total bill by about 15–17%. That’s still meaningful, but it’s why a holistic approach — combining consumption reduction with rate optimization and program participation — is so much more powerful.
Time-of-Use Pricing: The Single Biggest Lever You Have
Ontario’s Time-of-Use (TOU) pricing system — or its newer cousin, Ultra-Low Overnight (ULO) — is the most powerful free tool available to cut your hydro bill. Under TOU, the price you pay per kilowatt-hour (kWh) changes based on when you use electricity throughout the day.
Here are Ontario’s current TOU tiers for 2026, based on Ontario Energy Board rates [Source: OEB Rate Notices — oeb.ca/rates-and-your-bill/electricity-rates]:
Period | Time | Rate (¢/kWh) | Best Strategy |
Off-Peak | Weekdays: 7pm–7am Weekends & Holidays: All day | 7.4¢ | Run laundry, dishwasher, EV charging |
Mid-Peak | Weekdays: 11am–5pm | 10.2¢ | Reduce usage if possible |
On-Peak | Weekdays: 7am–11am & 5pm–7pm | 15.1¢ | Avoid major appliances — highest cost |
The math here is stark: using a major appliance during on-peak hours costs you more than twice what it would during off-peak. A simple shift in behaviour — running your dishwasher at 8pm instead of 6pm — literally costs you nothing and saves real dollars every month.
Tip 1: Shift Laundry and Dishes to Off-Peak Hours
This is the most commonly recommended tip for a reason: it works. Clothes washers, dryers, and dishwashers are among your highest-draw appliances. Running them after 7pm on weekdays or anytime on weekends drops your rate from 15.1¢/kWh to 7.4¢ — a 51% reduction in energy cost for those loads. Set a reminder, or better yet, use the delay-start feature most modern appliances include.
Tip 2: Consider Switching to Ultra-Low Overnight (ULO) Pricing
If your household includes an electric vehicle, an electric water heater, or anyone who works from home and can be flexible, ULO pricing may be a game-changer. The overnight rate under ULO drops to around 2.8¢/kWh — a fraction of on-peak rates. Ask your utility provider if this option is available to you. [Source: Hydro One ULO information — hydroone.com]
Quick Wins: No-Cost Changes That Add Up
Tip 3: Unplug Vampire Electronics
‘Phantom load’ or standby power drain is one of those invisible costs that adds up embarrassingly fast. The average Canadian home loses $100–$150 per year to devices that are off but still plugged in — TVs, gaming consoles, phone chargers, cable boxes, and especially old power bars.
The fix is simple: use smart power bars with remote switches, unplug devices you rarely use (that second TV in the guest room), and put your entertainment centre on a single switched bar. Natural Resources Canada has documented that standby power can account for 5–10% of a home’s total electricity use. [Source: NRCan — nrcan.gc.ca/energy-efficiency]
Tip 4: Switch to LED Lighting Everywhere
If you haven’t already made the full switch to LED lighting, this is genuinely one of the best ROI moves in home energy efficiency. LED bulbs use 75–80% less electricity than incandescent bulbs and last 15–25 times longer. A single incandescent bulb running 4 hours per day costs roughly $7–8 per year; an LED doing the same costs under $2. Multiply that across 20–30 fixtures and you’re looking at meaningful annual savings.
The Ontario government and many local utilities (including Hydro One and Toronto Hydro) have periodically offered rebate programs for LED retrofits — always worth checking before purchasing. [Source: Save on Energy — saveonenergy.ca]
Tip 5: Adjust Your Thermostat Strategically
Electric heating and cooling is among the biggest drivers of hydro usage in Ontario homes. Even without a smart thermostat, you can reduce electricity use significantly by setting your thermostat 2–3 degrees lower at night and when you’re out of the house. The rule of thumb is roughly a 3% savings in heating costs for every 1°C reduction.
If you heat with gas, this tip applies more to your gas bill — but summer cooling on electricity is still meaningfully impacted by thermostat discipline.
Smart Upgrades That Pay for Themselves
Tip 6: Install a Smart Thermostat
Ecobee and Nest thermostats are the two dominant options in the Canadian market, and both have proven track records of reducing heating and cooling costs by 10–23%. More importantly, some Ontario utilities — including Enbridge and several local distribution companies — offer rebates of $75–$100 on qualified smart thermostat purchases.
An Ecobee unit typically costs $200–$250, and with a $100 rebate plus 15% annual savings on your heating/cooling bill, payback periods of 12–18 months are common. [Source: Check eligibility at saveonenergy.ca or your local LDC’s rebate page]
Tip 7: Upgrade to an ENERGY STAR Refrigerator
Refrigerators run 24 hours a day, 7 days a week. An old fridge (pre-2010) can use 800–1,200 kWh per year, while a modern ENERGY STAR model uses 300–450 kWh. That difference — 400–700 kWh/year — translates to $30–$52 in annual savings at off-peak rates, or considerably more if you’re running it during on-peak hours.
Ontario’s Home Efficiency Rebate Plus (HER+) program has historically included rebates on major appliances. Always verify current availability before purchasing. [Source: Canada Greener Homes — canada.ca/en/natural-resources-canada/news/2021/05/canada-greener-homes-grant]
Tip 8: Add Insulation and Seal Air Leaks
This one isn’t purely an electricity tip — but for homes with electric baseboard heating or heat pumps, improving your building envelope has a direct impact on your hydro bill. Air sealing alone (caulking around windows, weatherstripping doors, sealing around electrical outlets) can reduce heating and cooling loads by 10–20%.
The Canada Greener Homes Grant program has offered up to $5,600 in rebates for eligible home upgrades including insulation. While program details change year to year, the fundamental principle — that better-insulated homes use less energy — is permanent.
Tip 9: Consider a Heat Pump
Heat pumps are having a major moment in Ontario, and for good reason. A cold-climate heat pump can deliver 2–3 units of heat for every 1 unit of electricity it consumes — making it dramatically more efficient than electric baseboard heating or even a gas furnace in certain conditions.
The upfront cost is substantial ($4,000–$10,000+ installed), but between federal and provincial incentives, the net cost can be significantly reduced. If you’re already on electric heat, this upgrade often delivers 30–50% reductions in heating costs. [Source: NRCan Heat Pump Guide — nrcan.gc.ca]
Behavioural Changes That Make a Real Difference
Tip 10: Use Cold Water for Laundry
About 90% of the energy used by a washing machine goes toward heating water. Switching to cold water washing eliminates that cost almost entirely. Modern cold-water detergents (Tide Coldwater, for example) are formulated to work just as effectively as warm-water washing for everyday loads. If your household does 5–7 loads per week, this single change can save $50–$80 per year.
Tip 11: Run Full Loads Only
Dishwashers and washing machines use roughly the same amount of electricity whether they’re half-full or completely full. Waiting until you have a full load before running either appliance cuts the number of cycles in half — and cuts that portion of your bill accordingly.
Tip 12: Air-Dry Dishes and Clothes When Possible
Disabling the heated drying cycle on your dishwasher and air-drying dishes instead can reduce the appliance’s electricity consumption by 15–50%. Similarly, line drying clothes (even indoors on a rack during Ontario winters) eliminates dryer costs entirely for those loads. A clothes dryer running once per day costs roughly $11–15 per month at off-peak rates — so even partial substitution adds up.
Tip 13: Take Shorter, Cooler Showers (If You Have Electric Hot Water)
If your water heater runs on electricity, your shower habits have a direct line to your hydro bill. Electric water heaters are often the second-largest electricity user in a home after HVAC. Reducing average shower time from 10 minutes to 6 minutes — across a household of four people — can save tens of kilowatt-hours per month. Installing a low-flow showerhead (which reduces water volume without sacrificing pressure) amplifies the effect.
Program Participation: Money You’re Leaving on the Table
Tip 14: Enroll in Ontario’s Ontario Electricity Rebate (OER) and Other Programs
The Ontario Electricity Rebate (OER) provides an 11.7% reduction on eligible electricity costs for residential customers — but you need to apply for it through your local distribution company. Most people are automatically enrolled, but if you moved recently, are renting, or changed utility accounts, it’s worth confirming you’re receiving this credit.

Additionally, the First Nations Delivery Credit and the Low-income Energy Assistance Program (LEAP) provide targeted support for eligible households. Energy Affordability Program (EAP) participants can receive free energy efficiency upgrades. [Source: OEB EAP — oeb.ca/rates-and-your-bill/electricity-rates/energy-affordability-program]
Tip 15: Use Your Utility’s In-Home Energy Audit
Hydro One and many local distribution companies offer free or subsidized home energy audits. An energy auditor will walk through your home, identify your biggest electricity drains, and recommend targeted upgrades — some of which may be eligible for on-the-spot rebates or zero-interest financing.
Even if you implement only 30% of the auditor’s recommendations, the average Ontario household that participates in a home energy assessment saves $200–$400 per year. That’s a return worth booking the appointment for. [Source: Hydro One Home Assistance Program — hydroone.com/saving-money-and-energy]
By the Numbers: What’s Actually Using Your Electricity?
Understanding which appliances are your biggest energy hogs helps you prioritize where to focus. The table below shows typical wattage and estimated monthly costs for common Ontario household appliances (calculated at off-peak rates of 7.4¢/kWh):
Appliance | Avg. Wattage | Daily Usage | Monthly Cost (Off-Peak) |
Electric Water Heater | 4,000W | 3 hrs | ~$26.64 |
Clothes Dryer | 5,000W | 1 hr | ~$11.10 |
Refrigerator | 150W | 24 hrs | ~$8.03 |
Dishwasher | 1,800W | 1 hr | ~$4.00 |
Desktop Computer | 200W | 4 hrs | ~$1.78 |
LED TV (55″) | 80W | 4 hrs | ~$0.71 |
A Real-World Example: The Moreau Family in Barrie
To make this concrete, consider a fictional-but-realistic scenario: the Moreau family — two adults, two kids — in a 1,800 sq ft home in Barrie, Ontario. They were paying $185/month on hydro when they started tracking their usage in early 2025.
Over six months, they made the following changes: shifted all laundry and dishwasher use to off-peak hours, replaced 18 incandescent bulbs with LEDs, installed an Ecobee thermostat (with a $75 utility rebate), started air-drying dishes, confirmed their OER enrollment, and got a home energy audit through their LDC.
By the end of those six months, their average monthly bill had dropped to $128 — a reduction of $57/month or roughly 31%. Their one-time cost for the thermostat was offset by the rebate, making the net investment under $150. Total annual savings: ~$684.
Not every household will see these exact results. But the Moreaus’ experience reflects what’s achievable when you combine multiple strategies — and it illustrates why no single tip in isolation is as powerful as a systematic approach.
Common Mistakes That Keep Your Hydro Bill High
Even well-intentioned Ontarians often make a few errors that limit their savings. The biggest one is running large appliances during on-peak hours out of habit — especially loading the dishwasher after dinner at 6pm rather than waiting until 7pm. That one-hour difference halves your electricity cost for that cycle.
Another common mistake is ignoring delivery charges and focusing only on energy consumption. As we covered earlier, delivery charges are fixed regardless of how much you use. Some frugal homeowners become so obsessed with turning off lights that they miss the bigger opportunities: water heaters, HVAC, and appliance timing.
Finally, many renters assume they can’t do anything about their hydro costs. That’s simply not true. TOU shifting, LED swaps, cold-water laundry, air-drying, and unplugging vampires are all renter-accessible strategies that can meaningfully reduce electricity bills regardless of who owns the appliances.
Putting It All Together: Your 30-Day Hydro Savings Plan
Rather than overwhelming yourself trying to implement everything at once, here’s a practical sequencing:
Week 1 — Zero-cost wins: Shift laundry and dishwasher to off-peak, unplug vampire electronics, confirm your OER enrollment, set thermostat back 2°C overnight.
Week 2 — Small investments: Replace remaining incandescent bulbs with LEDs, install a smart power bar on your entertainment centre, switch to cold water washing.
Week 3 — Research and planning: Book a home energy audit, research smart thermostat rebates from your LDC, review your water heater settings (many are factory-set too high at 60°C — 49°C is sufficient for most households).
Week 4 — Evaluation: Compare your electricity usage data in MyHydro or your utility’s app with the previous month. The data will show exactly which changes made the biggest impact in your specific home.
By the end of the month, most households see a measurable reduction without a single major purchase. The bigger upgrades — smart thermostat, efficient appliances, heat pump — compound on top of that baseline.
Conclusion: Lower Hydro Bills in Ontario Are Within Reach
The hydro bill in Ontario can feel like a fixed, unavoidable expense — but as these 15 strategies show, there’s actually significant room to take control. The key insights to take away:
- Time-of-use rate shifting is the most powerful free tool available — use it.
- Your biggest energy users are water heating, HVAC, and large appliances — focus there, not on phone chargers.
- Program participation (OER, home audits, rebates) is money you’ve already earned — claim it.
- A combination of behavioral changes + smart upgrades typically delivers 20–35% annual savings for Ontario households.
- Renters can implement most of these strategies — don’t assume you’re stuck.
The average Ontario household spending $1,400/year on hydro could realistically reduce that to $900–$1,050 with a committed, multi-pronged approach. That’s $350–$500 back in your pocket every year — money better spent on literally anything else.
