What you'll actually save each month
GrandBridge Energy delivers the power to Cambridge homes, but the price per kilowatt-hour comes from the province, not the local utility — the Ontario Energy Board sets one Regulated Price Plan for the whole province, updated twice a year.
- Electricity (OEB RPP, Nov 2025–Oct 2026): time-of-use pricing is 9.8¢/kWh off-peak, 15.7¢/kWh mid-peak, 20.3¢/kWh on-peak, averaging 12.8¢/kWh across a typical bill; tiered pricing runs 12.0¢/kWh then 14.2¢/kWh past the threshold. (Verify against the OEB's report →)
- Natural gas (Enbridge): Enbridge's rates split across four delivery zones and change every quarter, so quoting one number would be misleading. (Check your zone's current rate →)
Given the cold snaps that hit Waterloo Region harder than the seasonal average suggests, the equipment spec matters as much as the rate math: a cold-climate heat pump keeps moving 2.5–3.5 units of heat per unit of electricity even well below freezing, which is the whole reason the coefficient of performance stays favourable through a real Cambridge winter rather than just on a mild December day.

Common questions
How much is the heat pump rebate in Cambridge?
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 Cambridge's winters?
Yes. Cambridge's 10-year (2015-2024) average January low is -8.6°C, unremarkable for inland southwestern Ontario, but the coldest night on record hit -31.3°C — nearly 23 degrees below average and exactly the kind of outlier a cold-climate model (rated to roughly -25°C or below) is built to handle.
Cambridge's own utility
Cambridge is billed by GrandBridge Energy, formed in 2022 when Energy+ (which served Cambridge and North Dumfries) merged with Brantford Power. It's a different distributor from neighbouring Kitchener and Waterloo, which are served by Enova Power. That distinction doesn't cost you anything on the rebate side, since the heat pump rebate is a fixed provincial amount regardless of biller. Where it can matter: GrandBridge is who to contact about panel-capacity questions or electrical service ahead of your install. No GrandBridge-specific heat pump incentive has turned up beyond the provincial program.
Cambridge's cold snaps run deeper than its average suggests
The 10-year average January low in Cambridge (2015-2024) is -8.6°C, unremarkable for inland southwestern Ontario. What stands out is the gap to the coldest night recorded in that window: -31.3°C, nearly 23 degrees below the average. That's the kind of extreme-cold outlier a cold-climate heat pump (rated to roughly -25°C or below) is specifically built for, and it's a good reminder that the average number alone doesn't tell the whole story.
