What a Oakville winter means for your heat pump
The building code uses −18 °C for Oakville, with 3,760 degree days. That is three degrees milder than Markham or Richmond Hill, so a heat pump can carry more of the winter on its own.
Climate figures: Ontario Building Code, SB-1 (2024).
Power and panels in Oakville
Oakville has its own electricity distributor, Oakville Hydro. If your panel needs an upgrade for a heat pump, that is who your electrician coordinates with. Our electrical guide explains what to look for.
Rebates for Oakville homeowners
A qualifying home may get the federal rebate of $2,000, or up to $10,000 at or below the median income, for installs from November 1, 2026. The Ontario rebate needs pre-approval before work starts. Read the full rebate guide.

Common questions
Is a backup furnace needed in Oakville?
Not always. At −18 °C many cold-climate heat pumps can still do the job on their own, if they are sized for your home’s heat loss. Some homeowners keep the furnace as a backup, and we can look at both.
Are heat pump rebates different in Oakville?
No. The Ontario and federal programs are not set city by city. What changes the amount is your home, your equipment and, for the federal rebate, your household income.
