Montreal has more days where heat is a problem (ex: for elderly people), than when cold is a problem. There are a lot of efforts put into reducing heat zones, from too much asphalt, not enough trees, etc. (I once ran for borough council :-) Since 2010, most Quebec building standards have also been updated pretty massively. I don't have references, but where I live, we had 1" insulation in the walls, and now the minimum requirement for new buildings is 1.5". Doors and windows tech have improved a lot too in the past 10-15 years. Overall, as I went through upgrades, our heating bills went down pretty significantly, but AC usage keeps going up.
