The question relates to what's called PACE, property assessed clean energy, financing. That's a mechanism whereby municipalities can finance energy retrofits in homes or other buildings and have homeowners repay that over a long period of time through the property tax system. We've seen it succeed in some markets in Canada. It has widespread use in the United States as well. I think it makes home retrofits more achievable for many people.
There are still challenges. For example, many PACE programs require homeowners to get the consent of their primary mortgage holder, and most banks will not approve that for people on the middle- to lower-income spectrum. Unless programs are enhanced for them, they won't necessarily make it accessible for lower-income households, though that's a challenge that could be managed in different ways, such as loan guarantees or loan loss reserves that would offset the risk for banks.
It is a good mechanism, though. It's been used in many markets. We have it here in Toronto, and hundreds of homeowners have taken part already. It's a promising mechanism, and it's good as a complement to things like the greener homes grant program. You have that small rebate to get homeowners interested in putting in a heat pump or insulating their home, and then you have a municipal financing PACE program to help them recover the residual costs. I think it works quite well with that kind of program.
