How to Lower Your Winter Heating Bill in Ontario
Heating is the biggest chunk of most Ontario energy bills in winter. Here’s a practical, no-nonsense list of ways to bring it down — starting with the free stuff and working up to upgrades that pay for themselves.
Free and cheap first
- Lower the thermostat a few degrees. Every degree back saves energy. A programmable or smart thermostat that dials things down while you sleep or are out can cut a meaningful slice off your bill.
- Change the furnace filter. A clogged filter makes the furnace work harder for less heat. Check it monthly in winter.
- Seal the obvious leaks. Weatherstrip doors, caulk drafty windows, and block gaps where cold air sneaks in. Draft-proofing is cheap and effective.
- Use the sun. Open curtains on south-facing windows during the day, close them at night to keep heat in.
- Reverse ceiling fans. Run them clockwise on low to push warm air back down.
Upgrades that pay off
- Add insulation. Attic and wall insulation is one of the highest-return efficiency upgrades — and it’s rebate-eligible.
- Upgrade an old furnace. Going from a 70–80% AFUE furnace to a modern 95%+ condensing model means more of every dollar of gas becomes heat.
- Consider a heat pump. A cold-climate heat pump can heat efficiently for much of the Ontario winter — see our heat pump guide.
Let rebates do some of the lifting
Here’s the part that changes the math: insulation, high-efficiency furnaces, and heat pumps are all rebate-eligible in Ontario. The incentives can offset a real chunk of the upgrade cost — see our rebates guide for what’s available and how to claim it.
