Paying more on your hydro bill than you should? You’re not alone. Across Toronto and the Greater Toronto Area (GTA), homeowners are dealing with rising energy costs. But here’s the good news: you can cut your monthly utility bills without compromising comfort, and it starts with smart renovations.
At RM Renovation in GTA, we help Ontario homeowners make energy-saving improvements that reduce waste, increase comfort, and boost resale value. Whether you’re planning a full home renovation or making upgrades one step at a time, this guide will show you exactly how to lower energy bills with targeted renovations.
Why Renovations Help Reduce Energy Costs in Ontario
Ontario’s climate throws us big challenges: cold winters, humid summers, and rising hydro rates. Homes built before 2000 often lack proper insulation, sealed ductwork, or efficient heating systems.
Renovating for energy efficiency allows you to:
- Lower heating and cooling bills
- Qualify for Ontario and Canada-wide rebates
- Improve year-round comfort
- Add value to your home or investment property
If you’re planning a whole home renovation in Toronto, now’s the time to include energy efficiency in your design.
Renovation Strategies That Help Lower Energy Bills in Ontario
Discover proven renovation strategies that Ontario homeowners use to cut energy costs, boost comfort, and qualify for valuable rebate programs year-round.
1. Upgrade Insulation to Reduce Heat Loss Fast
Older Toronto homes lose heat quickly through attics, basements, and exterior walls. Upgrading insulation is one of the most effective ways to lower your energy bills.
We typically focus on attic insulation first, especially in homes built before 1990. Basement walls and ceilings are often neglected, but offer a major opportunity for improvement. For homeowners in Toronto and Mississauga, this upgrade alone can result in hundreds in annual savings.

2. Seal Air Leaks to Stop Wasting Energy
Drafty homes don’t just feel uncomfortable; they burn money. Unsealed gaps around windows, doors, attic hatches, and vents are major energy-wasters.
Smart Fixes:
- Weatherstripping exterior doors
- Caulking window frames and baseboards
- Sealing vents, plumbing holes, and attic entrances
A well-sealed home means your furnace and AC don’t have to work as hard. Pair this with flooring and tiling upgrades to boost thermal comfort room by room.
3. Replace Windows and Doors with Energy-Efficient Options
One of the biggest energy leaks? Old windows and doors. Upgrading to energy-efficient models can dramatically reduce heat transfer in both summer and winter while improving indoor comfort.
According to expert installers from Smart Tech Windows and Doors in Winnipeg, choosing triple-pane windows with low-E glass and argon gas fills can cut heat loss by up to 30%. For homeowners in the GTA, this is one of the most effective upgrades for controlling hydro costs year-round.
What You Should Choose:
- Double or triple-pane glass with thermal breaks
- Energy Star-certified windows designed for Ontario
- Low-E coatings to reduce solar heat gain
- Insulated exterior doors with high R-value cores
We can include window and door upgrades in your full renovation or as a standalone service.
4. Modernize HVAC Systems and Thermostats
An old furnace can waste 30–40% of the energy it uses. Replacing it with a high-efficiency unit is a smart move, especially when paired with modern thermostats and zoning controls.
We Recommend:
- Heat pumps – efficient in all seasons and eligible for rebates
- High-efficiency furnaces (AFUE > 95%) with ECM motors
- Smart thermostats – optimize heating/cooling schedules 24/7
These upgrades fit well into home additions or kitchen renovations and offer fast payback periods in homes across Vaughan, Oakville, and North York.
5. Use Ontario Rebates to Cut Costs
You don’t have to shoulder the full cost of energy upgrades alone. Multiple rebate programs in Ontario help homeowners recover thousands on qualifying renovations and retrofits.
Available Programs:
- Canada Greener Homes Grant – up to $5,000 for key upgrades
- Enbridge Gas Home Efficiency Rebate Plus (HER+)
- City of Toronto Home Energy Loan Program (HELP)
We help homeowners navigate eligibility, energy audits, and applications through our contact form to maximize your savings.
6. Improve Efficiency Through Kitchen and Bathroom Renovations
Renovations aren’t just about walls and roofs. Even bathroom and kitchen updates can lower energy usage with the right materials and fixture choices.
Upgrades You Can Try:
- Low-flow showerheads and faucets to save hot water
- Energy Star-rated dishwashers and induction cooktops
- Exhaust fans with timers to reduce runtime
- LED lighting systems for low-energy, high-output lighting

7. Optimize Lighting and Plug-in Appliances
Switching to LED lighting reduces lighting-related energy use by up to 80%. Add dimmer switches, motion sensors, and smart timers to increase savings across the home.
Other Quick Fixes:
- Insulated window coverings for seasonal temperature control
- Smart power strips to eliminate phantom loads on electronics
- Ceiling fans to reduce AC reliance in spring and summer
If you’re renovating your living room or bedrooms, we can integrate lighting controls and appliance placement into the design.
