Attic and cathedral-ceiling insulation don't need an assessment on their own (up to $1,250 / $750). But if you're already booking one for wall or foundation work, route the attic through that tier instead, it pays $1,500 for attic and $780 for cathedral ceiling.
What's different about doing this in Richmond Hill
Richmond Hill runs on Alectra Utilities for power and Enbridge Gas for heat, and unlike Toronto's HELP loan there's no city-run financing program here yet, Richmond Hill is currently studying a joint retrofit-financing initiative with neighbouring Markham, but nothing has launched as of this writing. That leaves the provincial HRSP numbers below as the actual available stack. Richmond Hill's housing mix skews toward larger detached homes built from the 1980s onward, which typically means the exterior-wall and foundation tier (up to $3,600 and $1,500) covers more square footage than in an older, smaller-lot city.
How to claim it
- Attic/cathedral ceiling: no assessment needed, hire a participating contractor, complete the work, they file the paperwork.
- Wall/foundation/crawlspace: book the pre-retrofit assessment, complete the work, then a follow-up assessment confirms it for the rebate.

Common questions
What insulation rebates are available in Richmond Hill?
Attic and cathedral-ceiling top-ups qualify with no assessment (up to $1,250 / $750). Wall, foundation, crawlspace, and exposed-floor work qualify on the assessment-required tier, up to $3,600 for exterior walls. Richmond Hill doesn't yet have its own program on top of these, the City is studying a joint retrofit-financing initiative with Markham, but nothing has launched.
Do I need an energy audit first in Richmond Hill?
Only for the wall, foundation, and crawlspace tier. Attic and cathedral-ceiling insulation can go through a participating contractor directly, no assessment required.
Alectra's size cuts both ways for Richmond Hill homeowners
Richmond Hill sits inside Alectra Utilities' territory, the product of one of Ontario's largest utility mergers, Alectra now serves roughly a million customers across more than a dozen municipalities north and west of Toronto. That scale means processes tend to be standardized and well-documented, which can make a panel-capacity question or a service-upgrade request move faster than with a smaller commission. It has no bearing on your insulation rebate amount, which is set provincially. We haven't found an Alectra-specific insulation top-up; if an installer references one, ask for the program name and confirm it directly with Alectra before counting on it.
Richmond Hill's winters, and what they cost you through a thin wall
Insulation rebates exist because heat loss is proportional to the temperature gap between your living room and the outside air, the bigger that gap, the more energy a poorly insulated wall or attic hands back to the winter. Over the last 10 years (2015-2024), Richmond Hill's average January low has run -9.1°C, with a recorded extreme of -28.2°C. Every degree below freezing on that chart is a degree your furnace has to fight to replace, which is exactly what closing an insulation gap stops from happening.
