What you'll actually save each month
Markham runs on the same Alectra Utilities delivery network as most of the GTA now, but the commodity price behind that delivery is province-wide, set once by the Ontario Energy Board and applied to every Ontario city the same way.
- Electricity (OEB RPP, Nov 2025–Oct 2026): 9.8¢/kWh off-peak, 15.7¢/kWh mid-peak, 20.3¢/kWh on-peak on time-of-use billing, averaging 12.8¢/kWh; tiered billing is 12.0¢/kWh then 14.2¢/kWh past the threshold. (Source: OEB price report →)
- Natural gas (Enbridge): no single honest figure, since delivery zones differ and rates reset every quarter. (Check your current zone rate →)
Markham stays close to Toronto's temperatures with a bit more bite in the cold snaps, and that's exactly the range a cold-climate heat pump is built for. It keeps moving 2.5 to 3.5 units of heat per unit of electricity it consumes (its coefficient of performance) well below freezing, not just on the mild GTA days that skew the seasonal average.

Common questions
How much is the heat pump rebate in Markham?
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 Markham's winters?
Yes. Markham's 10-year (2015-2024) average January low is -8.4°C, about a degree colder than Toronto's just to its south, with a coldest night on record of -27.8°C. Both figures stay within a cold-climate heat pump's rated range of roughly -25°C or lower.
Markham runs on the same utility as most of the GTA now
Markham's electricity comes from Alectra Utilities, the company formed in 2017 when PowerStream — which served Markham directly before the merger — combined with Enersource, Horizon Utilities, and Brampton Hydro. Your rebate doesn't move either way; it's a fixed provincial amount. The upside of being on a utility this large is that panel-capacity approvals and similar install-side paperwork tend to follow a more standardized process than a small independent utility runs. No Alectra-specific heat pump incentive beyond the provincial program has come up in our research.
Markham stays close to Toronto's numbers, with a bit more bite
Over 2015-2024, Markham's average January low sat at -8.4°C, roughly a degree colder than Toronto just to its south, a small but consistent gap tied to being further from Lake Ontario's shoreline. The coldest night recorded across that decade was -27.8°C. Both figures stay within the working range of a cold-climate heat pump, which is built to keep pulling heat efficiently down to around -25°C or colder.
