What a Mississauga winter means for your heat pump
The building code uses −18 °C for Mississauga and Port Credit, and −20 °C at Pearson Airport. Degree days run from 3,780 in Port Credit to 3,890 at Pearson, so with everything else equal a home near the airport needs a little more heat than one by the lake.
Climate figures: Ontario Building Code, SB-1 (2024).
Power and panels in Mississauga
Mississauga’s electricity distributor is Alectra Utilities. A heat pump usually needs its own circuit, so the first thing to check is whether your panel has room. Our electrical guide explains what to look for.
Rebates for Mississauga 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
Does a heat pump make sense in Port Credit?
The code’s design temperature there is −18 °C, well within what cold-climate models are built for; many still produce heat at −25 °C. A heat-loss calculation for your home still decides the size.
Are heat pump rebates different in Mississauga?
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.
