What you'll actually save each month
Windsor's mild winters (see below) help a heat pump's case, but the number that actually decides your monthly bill is the rate you're charged per kWh and per unit of gas, not the weather.
- Electricity, OEB Regulated Price Plan (Nov 2025–Oct 2026): 9.8¢/kWh off-peak, 15.7¢/kWh mid-peak, 20.3¢/kWh on-peak for time-of-use accounts, averaging 12.8¢/kWh; tiered accounts pay 12.0¢/kWh then 14.2¢/kWh past the monthly threshold. EnWin bills you, but the Ontario Energy Board sets this rate the same way for every utility in the province. (OEB price report →)
- Natural gas (Enbridge): Windsor falls in Enbridge's Union South delivery zone, and like the other three zones, its rate resets every quarter, so there's no fixed figure worth printing. (Check this quarter's Enbridge rate →)
What makes the switch pay off is a cold-climate heat pump's coefficient of performance: it moves roughly 2.5 to 3.5 units of heat into your home per unit of electricity used, well ahead of electric resistance heating's 1-to-1 ratio. Against gas, the comparison shifts with this quarter's Union South rate and your home's insulation, so there's no single savings figure that's accurate for every Windsor house.

Common questions
How much is the heat pump rebate in Windsor?
It depends on your current heating fuel. Enbridge Gas customers get up to $2,000 for an air-source heat pump or $3,000 for ground-source. If you heat with electric, oil, propane, or wood, you get up to $7,500 (air-source) or $12,000 (ground-source). This is the same structure across all of Ontario.
Is a heat pump worth it in Windsor's winters?
Yes, and Windsor is about as easy a case as Ontario gets: the 10-year (2015-2024) average January low is just -6.2°C, the mildest in this comparison, and even the coldest night recorded, -28.0°C, stays within reach of a qualified cold-climate model. Cold-weather performance isn't a real concern here.
EnWin, the utility born from combining water and hydro
EnWin Utilities came together in 2002 when the city merged Windsor's hydro and water commissions into one company. So if you've ever had a water bill from the same place as your electricity bill here, that's why. None of that changes your rebate math; the amounts above are set by the province regardless of who bills you. What EnWin does control is your electrical service capacity, so if a panel upgrade comes up mid-quote, they're the call to make. No EnWin-specific heat pump top-up has surfaced beyond the provincial program as of this writing.
Windsor is about as mild as Ontario heat pump weather gets
Windsor sits at Ontario's southern tip, and it shows in the numbers: a 10-year (2015-2024) average January low of just -6.2°C, the mildest of any Ontario city in this comparison. Even the coldest night on record in that decade, -28.0°C, stayed within what a cold-climate heat pump handles without breaking a sweat. If cold-weather performance is what's holding you back from switching, Windsor is close to the best-case scenario in this province.
